Resumo: Infectious laryngotracheitis (ILT), caused by an Alphaherpesvirus (Gallid herpesvirus-1; GaHV-1), has been noticed in the region of the Terras Altas da Mantiqueira, Minas Gerais. From 2010 to 2018, the "Serviço Veterinário Oficial" (SVO) of the "Instituto Mineiro Agropecuário" (IMA), implemented measures to prevent spread of the virus to other regions and control the disease in the area. Due to the close proximity and consequent epidemiological link among farms, the region was considered a unique epidemiological unit. To check the efficiency of the ILT control measures, we carried out: (1) a seroepidemiological survey, (2) questionnaires for evaluating biosecurity measures; and (3) an evaluation of the influence of farm population density on the occurrence of ILT. In 2016, 2017, and 2018, ILT was investigated using epidemiological and clinicopathological methods, along with GaHV-1 molecular detection. Serological survey was carried out on 24 farms in the quarantined region and on 13 farms from other regions of the state. In 2010 and 2018, questionnaires were applied to collect data and determine indicators of biosecurity practices in all farms of the quarantined area. The differences were then assessed (Wilcoxon's p<0.05). The results indicated positive serology throughout the region, although only on four farms (16.6%) the chickens have clinical signs, macroscopic and histological lesions of ILT. The prevalence of viral infection increased from 2016 (27%) to 2017 (50%) and was higher in farms with a high stock density (p=0.033). No disease, virus or antibodies were detected in the farms outside of the quarantined area. Although the biosecurity indicators had improved on all farms in the quarantined area (p<0.05), the virus was active and circulating in the region. The contingency measures have contained the outbreak, but biosecurity practices are paramount in the control of new outbreaks. Official control will be maintained in the region, including surveillance of new cases and biosecurity procedures to mitigate the risk of the virus reaching other regions.(AU)

Laringotraqueíte infecciosa (LTI), causada por um alfaherpesvírus (herpesvírus Gallid-1; GaHV-1), foi observada na região das Terras Altas da Mantiqueira, Minas Gerais. De 2010 a 2018, o Serviço Veterinário Oficial (SVO) do Instituto Mineiro Agropecuário (IMA) implementou medidas para impedir a disseminação do vírus para outras regiões do estado e controlar a doença na região interditada. Devido à proximidade e consequente vínculo epidemiológico entre as granjas, a região foi considerada uma unidade epidemiológica única. Para verificar a eficiência das medidas de controle de LTI, foram realizados: (1) pesquisa soroepidemiológica, (2) questionários para avaliar medidas de biosseguridade; e (3) avaliação da influência da densidade populacional da granja na ocorrência de LTI. Em 2016, 2017 e 2018, a LTI foi investigada usando métodos epidemiológicos e clínico-patológicos, com a detecção molecular de GaHV-1. O levantamento sorológico foi realizado em 24 granjas da região interditada e em 13 granjas de outras regiões do estado. Em 2010 e 2018, foram aplicados questionários para coletar dados e determinar indicadores de medidas de biosseguridade em todas as granjas da área interditada. As diferenças foram avaliadas (p<0,05 de Wilcoxon). Os resultados indicaram sorologia positiva em toda a região, embora apenas em quatro granjas (16,6%) as galinhas apresentaram sinais clínicos, lesões macroscópicas e histológicas da LTI. A prevalência de infecção viral aumentou de 2016 (27%) para 2017 (50%) e foi maior em fazendas com alta densidade de alojamento (p=0,033). Presença da doença, vírus ou anticorpos foram detectados nas granjas fora da área interditada. Embora os indicadores de biosseguridade tenham melhorado em todas as fazendas da área interditada (p<0,05), o vírus está ativo e circulava na região. As medidas de contingência contiveram o surto, mas as práticas de biosseguridade são fundamentais para o controle de novos surtos. O controle oficial será mantido na região, incluindo a vigilância de novos casos e procedimentos de biosseguridade para mitigar o risco de transmissão do vírus para outras regiões.(AU)

Idioma: en.
Resumo: Avian colibacillosis is an acute and globally occurring infectious disease of domestic and wild birds caused by Escherichia coli, and it is associated with considerable economic losses mainly due to the morbidity and mortality associated. The present study aimed to describe the pathological, bacteriological and immunohistochemical aspects of avian colibacillosis in broiler chickens of Mozambique. Forty-nine broiler chicken presented anorexia, decreased weight gain, ataxia, diarrhea, dyspnea, and death in a clinical course of 3-5 days. The birds were raised in five farms (small, medium and large farms) with manual and automatic breeding system, with flocks ranging from 100 to 20,000 birds. At the necropsy, all birds had poor body condition, and the pericardium and the Glisson's capsule of all avian exhibited different degrees of adherence often associated with severe fibrin deposition. The thoracic and abdominal air sacs were thickened and adhered to the costal wall. Mild, moderate or marked hepatomegaly associated with white pinpoint multifocal areas (100%, 49/49) and mild to moderate splenomegaly in 75.5% (37/49) with a mottled surface were observed. The lungs and kidney were enlarged and reddish. Histologically, a multiorgan fibrinoheterophilic polyserositis was observed in 75.5% of the cases (37/49), which were characterized by inflammatory infiltrates composed mainly of degenerative heterophils, macrophages and plasma cells, associated with fibrin deposits and intermixed by coccobacillary bacterial basophilic aggregates. These affected mainly the pericardium (28.6%, 14/49), the pleura (18.4%, 9/49), the Glisson's capsule (10.2%, 5/49), the ventriculus (10.2, 5/33), and the proventriculus (8.2%, 4/49) serosa. Multifocal to coalescing areas of coagulative necrosis associated with similar inflammatory cells were observed mainly in the spleen (28.6%, 14/49), liver (24.5%, 12/49), and intestines (22.4%, 11/49). A similar infiltrate was also observed affecting the the lungs (16.3%, 8/49), the kidney (16.3%, 8/49) and the myocardium (14.3%, 7/49). Isolation and identification of E. coli was obtained in 12 cases through bacterial culture. Some organs (2 cases of each farms) were selected and submitted to immunohistochemistry anti-E. coli, and a positive stain was observed in all tested cases in liver (3/3), heart (4/4), spleen (1/1), lungs (4/4), intestines (4/4), bursa of Fabricius (1/1), ventriculus (1/1), and proventriculus (1/1) tissue sections. These results demonstrate that E. coli was the cause of mortality in these birds. Therefore, biosecurity and management measures should be employed to prevent and control the disease occurrence in Mozambique's poultry farming.(AU)

A colibacilose aviária é uma doença aguda de ocorrência mundial que acomete aves domésticas e silvestres, causada por Escherichia coli e resulta em perdas econômicas consideráveis devido à elevada morbidade e mortalidade das aves. O presente estudo teve o objetivo de descrever os aspectos patológicos, bacteriológicos e imuno-histoquímicos de colibacilose aviária em frangos de corte de Moçambique. Um total de 49 frangos de corte apresentaram anorexia, baixo ganho de peso, ataxia, diarreia, dispneia e morte em um curso clínico de 3 a 5 dias. As aves eram provenientes de 5 granjas (pequenas, média e grandes), com sistema de criação manual e automático, com rebanhos que variavam de 100 a 20.000 aves. À necropsia, todas as aves exibiam condição corporal ruim a caquética, além de pericárdio e cápsula de Glisson de todas aves (100%; n=49) com diferentes graus de aderência e deposição de fibrina de forma difusa acentuada. Os sacos aéreos torácicos e abdominais estavam espessados e aderidos à parede costal. Foi observado ainda hepatomegalia discreta, moderada a severa frequentemente associada com áreas multifocais puntiformes brancacentas (100%; 49/49), e esplenomegalia discreta a moderada, associado a áreas multifocais moteadas (75,5%; 37/49). Os pulmões e rins estavam aumentados e com coloração avermelhada. Histologicamente, observou-se majoritariamente serosite fibrinoheterofílica em 75,5% dos casos (37/49), caracterizadas por infiltrado inflamatório composto por heterófilos degenerados, macrófagos, linfócitos e plasmócitos, com deposição de fibrina entremeada por uma miríade de estruturas bacterianas cocobacilares. Esta lesão foi observada principalmente em pericárdio (28,6%; 14/49), pleura (18,4%; 9/49), cápsula de Glisson (10,2%; 5/49), ventrículo (10,2; 5/33) e em proventrículo (8,2%; 4/49). Áreas multifocais a coalescentes de necrose de coagulação associada a infiltrado inflamatório semelhante ao descrito foi observado principalmente no baço (28,6%; 14/49), fígado (24.5%; 12/49), e intestinos (8,2%; 4/49). Um infiltrado inflamatório semelhante também foi visualizado em pulmões (16,3%; 8/49), rins (16,3%; 8/49) e miocárdio (14,3%; 7/49), Colônias puras de E. coli foram identificadas e isoladas em 12 casos. Alguns órgãos (2 de cada granja) foram submetidos ao exame imuno-histoquímico anti-E. coli e marcação positiva foi visualizada em todos casos testados, como em fígado (3/3), coração (4/4), baço (1/1), pulmão (4/4), intestinos (4/4), bursa de Fabricius (1/1), rim (1/1), ventrículo (1/1) e proventrículo (1/1). Estes resultados demonstram que E. coli foi a causa de morte destas aves. Sendo assim, a adoção de boas medidas de biosseguridade e de manejo são indispensáveis para a prevenção e controle da ocorrência da doença nas granjas de frango de corte de Moçambique.(AU)

Idioma: es.
Resumo: Resumen Introducción: Los alimentos de origen animal frecuentemente están implicados en brotes de salmonelosis. Objetivo: Evaluar la frecuencia de Salmonella enterica en carnes molidas de pollo, res y cerdo (un total de 2.592 muestras) obtenidas de mercados sobre ruedas y supermercados de la Delegación Iztapalapa en la Ciudad de México, determinar la susceptibilidad antimicrobiana y efectuar ensayos de adherencia en las cepas aisladas. Métodos: El aislamiento de S. enterica se hizo de acuerdo a la BAM-FDA, la susceptibilidad antimicrobiana de acuerdo con CLSI y el ensayo de adherencia en células HEp-2 conforme a Baffone y cols., 2001. Resultados: Salmonella enterica fue aislada en 511 del total de muestras analizadas (19,7%), de las cuales 244 (47,7%), 152 (29,7%) y 115 (22,5%) correspondieron a carne molida de pollo, res y cerdo, respectivamente. La mayor frecuencia de resistencia de S. enterica a antimicrobianos fue a ampicilina y cloranfenicol en pollo, perfloxacina y ampicilina en res y carbenicilina, ampicilina, cloranfenicol, cefotaxima y perfloxacina en cerdo. Noventa por ciento de las cepas mostraron un patrón de adherencia agregativo. Conclusión: La frecuencia de S. enterica en productos cárnicos es alta, por lo que es importante la adecuada cocción de la carne para disminuir el riesgo de una salmonelosis.

Background: Food of animal origin is often involved in salmonellosis outbreaks. Aim: To evaluate the frequency of Salmonella enterica in chicken, beef and pork ground meat (a total of 2,592 samples) obtained from travelling markets and supermarkets at the Iztapalapa area of Mexico City, in order to determine the antimicrobial susceptibility and adherence capacity of isolated strains. Methods: Isolation of S. enterica was carried out according to the BAM-FDA, the microbial susceptibility according with CLSI and adherence assay on HEp-2 cell line according with Baffone et al., 2001. Results: S. enterica was isolated from 511 of all the analyzed samples (19.7%), from which 244 (47.7%), 152 (29.7%) and 115 (22.5%) corresponded to chicken, beef and pork ground meat, respectively. The highest frequency of resistance of S. enterica to antimicrobials was to ampicillin and chloramphenicol in chicken, perfloxacin and ampicillin in beef and carbenicillin, ampicillin, chloramphenicol, cefotaxime and perfloxacin in pork. Ninety percent of the strains showed an aggregative adherence pattern on HEp-2 cells. Conclusion: The frequency of S. enterica on meat products is high, which is the reason why a proper cooking of these ground meats is important in order to reduce the risk of acquiring salmonellosis.

Resumo: Avian pathogenic Escherichia coli (APEC) isolated from avian cellulitis lesions produces a toxin, named Escherichia coli vacuolating factor (ECVF), that causes cell vacuolization and induces inflammatory response in broiler chicken. Methods We investigated the intracellular activities of ECVF in avian fibroblasts using fluorescence staining, electron microscopy, MTT and LDH measurements. As ECVF act specifically in avian cells, we performed blotting assay followed by mass spectrometry to better understand its initial intracellular protein recognition. Results ECVF induced actin contraction, mitochondrial damage and membrane permeability alterations. Ultrastructural analysis showed intracellular alterations, as nuclear lobulation and the presence of degraded structures inside the vacuoles. Moreover, ECVF induced cell death in fibroblasts. ECVF-biotin associates to at least two proteins only in avian cell lysates: alpha-actinin 4 and vinculin, both involved in cytoskeleton structure. Conclusion These findings demonstrated that ECVF plays an important role in avian cellulitis, markedly in initial steps of infection. Taken together, the results place this toxin as a target for drug and/or vaccine development, instead of the use of large amounts antibiotics.(AU)

Resumo: BACKGROUND: Cocaine- and amphetamine-regulated transcript (CART), discovered initially by via differential display RT-PCR analysis of brains of rats administered cocaine, is expressed mainly in central nervous system or neuronal origin cells, and is involved in a wide range of behaviors, such as regulation of food intake, energy homeostasis, and reproduction. The hens egg-laying rate mainly depends on the developmental status of follicles, expression of CART have not been identified from hen follicles, the regulatory mechanisms of CART biological activities are still unknown. The objective of this study was to characterize the mRNA expression of CART in hen follicular granulosa cells and determine CART peptide localization and regulatory role during follicular development. METHODS: Small white follicles (1-2 mm in diameter) were treated for RNA isolation; Small white follicles (1-2 mm in diameter) and large white follicles (4-6 mm in diameter) were treated for immunohistochemical localization and large white follicles (4-6 mm in diameter), small yellow follicles (6-8 mm in diameter), large yellow follicles (9-12 mm in diameter), mature follicles (F5, F4, F3, F2, F1, >12 mm in diameter) were treated for RNA isolation and Real time PCR. RESULTS: The results showed that full length of the CDS of hen CART was 336 bp encoding a 111 amino acid polypeptide. In the hen ovary, CART peptide was primarily localized to the theca layer, but not all, the oocyte and granulosa layer, with diffused, weaker staining than relative to the theca cell layer. Further, amount of CART mRNA was more (P < 0.05) in granulosa cells of 6-8 mm follicles compared with that in granulosa cells of other follicles. However, CART mRNA amount was greater in theca cells of 4-6 mm follicles relative to follicles of other sizes (P < 0.05). CONCLUSIONS: Results suggest that CART could play a potential role in developmental regulation of chicken follicles.

Título: Infection rate by TOXOPLASMA GONDII in free-range and broiler chickens in the states of Rio Grande do Norte and Paraíba, Brazil
Fonte: Rev. patol. trop;50(2):1-15, jun. 2021. ilus.
Idioma: en.
Resumo: Toxoplasmosis is a zoonosis caused by Toxoplasma gondii, a protozoan that has a cosmopolitan geographic distribution and low specificity for intermediate hosts. Domestic chickens are among the most important hosts in toxoplasmosis epidemiology, since they are potential sources of infection for humans, in addition to indicating environmental contamination by protozoa. In this work, we studied the prevalence of T. gondii infection in chickens in different breeding systems from distinct mesoregions of Rio Grande do Norte and Paraiba States: broiler chickens from commercial farms and free-range chickens from small farms. Indirect fluorescent antibody test (IFAT) and ELISA techniques were used for detecting specific antibodies in blood samples from the birds. There were no seropositive samples among the broilers tested, indicating that intensive management limited the chances of infection for these animals. Among the free-range chickens, the frequency of IgG anti-T. gondii detected by IFAT and ELISA were 37.9% and 40.4% respectively. Among the seropositive samples by IFAT, 33 (27.1%) were positive at a dilution of 1:16; in 1:32, 31 (25.4%); in 1:64, 24 (19.7%); 15 (12.3%) in 1:128, and 19 presented titers greater than or equal to 1:256 (15.6%). The substantial concordance observed between IFAT and ELISA signifies these methods are effective methodologies for the diagnosis of avian toxoplasmosis. The high prevalence of specific antibodies among poultry in the studied region highlights the potential risk of T. gondii transmission to humans through consumption of infected meat.

Título: Celecoxib decreases growth and angiogenesis and promotes apoptosis in a tumor cell line resistant to chemotherapy
Fonte: Biol. Res;47:1-9, 2014. ilus, graf.
Idioma: en.
Projeto: Fondo Nacional de Desarrollo Científico y Tecnológico, Chile.
Resumo: BACKGROUND: During the last few years it has been shown in several laboratories that Celecoxib (Cx), a non-steroidal anti-inflammatory agent (NSAID) normally used for pain and arthritis, mediates antitumor and antiangiogenic effects. However, the effects of this drug on a tumor cell line resistant to chemotherapeutical drugs used in cancer have not been described. Herein we evaluate the angiogenic and antitumor effects of Cx in the development of a drug-resistant mammary adenocarcinoma tumor (TA3-MTXR). RESULTS: Cx reduces angiogenesis in the chick embryonic chorioallantoic membrane assay (CAM), inhibits the growth and microvascular density of the murine TA3-MTXR tumor, reduces microvascular density of tumor metastases, promotes apoptosis and reduces vascular endothelial growth factor (VEGF) production and cell proliferation in the tumor. CONCLUSION: The antiangiogenic and antitumor Cx effects correlate with its activity on other tumor cell lines, suggesting that Prostaglandins (PGs) and VEGF production are involved. These results open the possibility of using Celecoxib combined with other experimental therapies, ideally aiming to get synergic effects.

Resumo: Se caracterizaron morfométrica, faneróptica y morfológicamente a gallinas y gallos de cuello desnudo (324 hembras, 60 machos) en los cuatro municipios de la región ch'ortí de Chiquimula. Las variables evaluadas fueron 18 cuantitativas para la hembra y 16 para el macho, nueve cualitativas y ocho índices zoométricos. El análisis de las variables zoométricas se realizó a través del procedimiento análisis univariado, con medidas de tendencia central y medidas de dispersión, y para analizar la proporcionalidad y armonía entre las diversas regiones corporales mediante la correlación de Pearson. Los resultados principales son: peso de 1.84 kg/hembra y 2.29 kg/macho; alzada 27.84 cm/hembra y 32.51 cm/macho; metatarso 10.25 cm/hembra y 11.76 cm/macho; ambos tienen más alzada que longitud, inclinados hacia adelante; en cuanto a sus perímetros, el abdominal es el mayor y curvado característica de las gallinas ponedoras y una grupa alargada con dorso plano. Sus índices corporales son aves alargadas, con capacidad reproductiva (índice pélvico 71.82%) y poca formación de músculo para la producción de carne (índice compacidad 6.80%/hembra y 7.03%/macho), cabeza alargada, tórax elíptico y miembros fuertes y altos. Las características morfológicas y fanerópticas describen un ave de piel blanca, metatarso amarillo, plumas en garganta, cresta simple con barbilla y orejuelas, los colores de pluma son la combinación de marrón, negro, gris y blanco, el color de la cáscara varia del blanco al marrón claro y con una armonización corporal hasta del 61% lo que le da una homogeneidad medianamente aceptable a la morfoestructura de la gallina.

Hens and roosters naked neck (324 females and 60 males) were characterized morphological and phenotypically in four villages of the ch'ortí area in the province of Chiquimula. Variables evaluated were 18 quantitative for females and 16 for males, nine qualitative and eight zoometrics ranges. The zoometric variables analyzed were made according to the univariate analysis procedure with measurements of central tendency and dispersion measurements to analyze the proportion and harmony between the different corporeal areas we used the Pearson correlation. In the results weight of 1.84 kg/female and 2.29 kg/male; raised 27.84 cm/female and 32.51cm/male; metatarsal 10.25 cm/female and 11.76 cm/male; the hen has more height than length, raised in the front, concerning to the perimeters, the abdominal is the biggest and curved, which is characteristic in lay eggs hens with flat dorsal. Corporeal indices, they are elongated birds, reproductive capability (pelvic index 71.82%) and less muscles developed to produce meat as food for humans (compactness index 6.80% female and 7.03% male), elongated head, elliptical thorax and long and strong extremities. Phenotypically and morphologically characteristics describe a bird with white skin, yellow metatarsus, feathering on the throat, simple crest, chin and earlobes, the feathering colors are a combination of brown, black, grey, and white, and the colors of the egg shell are from white to light brown, and also has a good corporal harmony up to 61%, which brings an acceptable mild homogeneity comparable to the structure of a hen.

Resumo: BACKGROUND: The study was conducted to evaluate the in vitro antimicrobial activity, cytotoxic, and membrane stabilization activities, and in vivo antiemetic and antipyretic potentials of ethanolic extract, n-hexane and ethyl acetate soluble fractions of Spilanthes paniculata leaves for the first time widely used in the traditional treatments in Bangladesh. RESULTS: In antipyretic activity assay, a significant reduction (P < 0.05) was observed in the temperature in the mice tested. At dose 400 mg/kg-body weight, the n-hexane soluble fraction showed the effect (36.7 ± 0.63°C ) as like as the standard (dose 150 mg/kg-body weight) after 5 h of administration. Extracts showed significant (P < 0.001) potential when tested for the antiemetic activity compared to the standard, metoclopramide. At dose 50 mg/kg-body weight, the standard showed 67.23% inhibition, whereas n-hexane and ethyl acetate soluble fractions showed 37.53% and 24.93% inhibition of emesis respectively at dose 400 mg/kg-body weight. In antimicrobial activity assay, the n-hexane soluble fraction (400 µg/disc) showed salient activity against the tested organisms. It exerts highest activity against Salmonella typhi (16.9 mm zone of inhibition); besides, crude, and ethyl acetate extracts showed resistance to Bacillus cereus and Bacillus subtilis, and Vibrio cholera respectively. All the extracts were tested for lysis of the erythrocytes. At the concentration of 1mg/ml, ethanol extract, and n-hexane and ethyl acetate soluble fractions significantly inhibited hypotonic solution induced lysis of the human red blood cell (HRBC) (27.406 ± 3.57, 46.034 ± 3.251, and 30.72 ± 5.679% respectively); where standard drug acetylsalicylic acid (concentration 0.1 mg/ml) showed 77.276 ± 0.321% inhibition. In case of heat induced HRBC hemolysis, the plant extracts also showed significant activity (34.21 ± 4.72, 21.81 ± 3.08, and 27.62 ± 8.79% inhibition respectively). In the brine shrimp lethality bioassay, the n-hexane fraction showed potent (LC50 value 48.978 µg/ml) activity, whereas ethyl acetate fraction showed mild (LC50 value 216.77 µg/ml) cytotoxic activity. CONCLUSIONS: Our results showed that the n-hexane extract has better effects than the other in all trials. In the context, it can be said that the leaves of S. paniculata possess remarkable pharmacological effects, and justify its folkloric use as antimicrobial, antipyretic, anti-inflammatory, and antiemetic agent. Therefore, further research may be suggested to find possible mode of action of the plant part.

Resumo: Abstract INTRODUCTION The occurrence of Triatoma sordida in the Brazilian Western Amazon is reported for the first time. METHODS Triatoma sordida specimens were collected from a Gallus gallus nest in a peridomiciliary area of Senador Guiomard municipality in the state of Acre. RESULTS The number of triatomine species in Acre increased from six to seven with this first report of T. sordida in the Brazilian Western Amazon. CONCLUSIONS The occurrence of T. sordida in Acre is of concern since it is among the most captured triatomines in peridomiciliary environments in Brazil, and carries a high potential for vector transmission.
