Título: Inactivation of phoPQ genes attenuates Salmonella Gallinarum biovar Gallinarum to susceptible chickens

Resumo: Abstract Salmonella Gallinarum is a host-restrict pathogen that causes fowl typhoid, a severe systemic disease that is one of the major concerns to the poultry industry worldwide. When infecting the bird, SG makes use of evasion mechanisms to survive and to replicate within macrophages. In this context, phoPQ genes encode a two-component regulatory system (PhoPQ) that regulates virulence genes responsible for adaptation of Salmonella spp. to antimicrobial factors such as low pH, antimicrobial peptides and deprivation of bivalent cations. The role of the mentioned genes to SG remains to be investigated. In the present study a phoPQ-depleted SG strain (SG ΔphoPQ) was constructed and its virulence assessed in twenty-day-old laying hens susceptible to fowl typhoid. SG ΔphoPQ did cause neither clinical signs nor mortality in birds orally challenged, being non-pathogenic. Furthermore, this strain was not recovered from livers or spleens. On the other hand, chickens challenged subcutaneously with the mutant strain had discreet to moderate pathological changes and also low bacterial counts in liver and spleen tissues. These findings show that SG ΔphoPQ is attenuated to susceptible chickens and suggest that these genes are important during chicken infection by SG.

Título: Campylobacter in broiler slaughter samples assessed by direct count on mCCDA and Campy-Cefex agar
Fonte: Braz. j. microbiol;47(3):764-769, July-Sept. 2016. tab.
Idioma: en.
Resumo: ABSTRACT Campylobacter spp. cause foodborne illnesses in humans primarily through the consumption of contaminated chicken. The aim of this study was to evaluate the United States Department of Agriculture's (USDA) recommended methodology, protocol MLG 41.02, for the isolation, identification and direct plate counting of Campylobacter jejuni and C. coli samples from the broiler slaughtering process. A plating method using both mCCDA and Campy-Cefex agars is recommended to recover Campylobacter cells. It is also possible to use this method in different matrices (cloacal swabs and water samples). Cloacal swabs, samples from pre-chiller and post-chiller carcasses and samples of pre-chiller, chiller and direct supply water were collected each week for four weeks from the same flock at a slaughterhouse located in an abattoir in southern Brazil. Samples were analyzed to directly count Campylobacter spp., and the results showed a high frequency of Campylobacter spp. on Campy-Cefex agar. For the isolated species, 72% were identified as Campylobacter jejuni and 38% as Campylobacter coli. It was possible to count Campylobacter jejuni and Campylobacter coli from different samples, including the water supply samples, using the two-agar method. These results suggest that slaughterhouses can use direct counting methods with both agars and different matrices as a monitoring tool to assess the presence of Campylobacter bacteria in their products.

Título: Occurrence and characteristics of extended spectrum beta-lactamases-producing Enterobacteriaceae from foods of animal origin
Fonte: Braz. j. microbiol;47(2):444-451, Apr.-June 2016. tab.
Idioma: en.
Resumo: Abstract Presence of extended spectrum beta-lactamases (ESBL) in bacteria is a growing health concern of global significance. The local, regional, national, and international epidemiological studies for extended spectrum beta-lactamases-producing Enterobacteriaceae and their encoding genes in foods are still incomplete. The objective of this study was to determine the occurrence of extended spectrum beta-lactamases-producing Enterobacteriaceae and the characteristics of their encoding genes from a total of 250 samples of various foods of animal-origin (100 raw chicken meat, 100 raw cow milk, and 50 raw cow milk cheese) sold in Turkey. Overall, 55 isolates were positive as extended spectrum beta-lactamases-producing Enterobacteriaceae. The most prevalent extended spectrum beta-lactamases-producing strain were identified as Escherichia coli (80%), followed by Enterobacter cloacae (9.1%), Citrobacter braakii (5.5%), Klebsiella pneumoniae (3.6%), and Citrobacter werkmanii (1.8%) by Vitek® MS. The simultaneous production of extended spectrum beta-lactamases and AmpC was detected in five isolates (9.1%) in E. coli (80%) and E. cloacae (20%). The frequency rates of blaTEM, blaCTX-M, and blaSHV were 96.4%, 53.7%, and 34.5%, respectively. The co-existence of bla -genes was observed in 82% of extended spectrum beta-lactamases producers with a distribution of blaTEM & blaCTX-M (52.7%), blaTEM & blaSHV (20%), blaTEM & blaCTX-M & blaSHV (12.7%), and blaSHV & blaCTX-M (1.8%). The most prevalent variant of blaCTX-M clusters was defined as blaCTX-M-1 (97.2%), followed by blaCTX-M-8 (2.8%). In summary, the analysed foods were found to be posing a health risk for Turkish consumers due to contamination by Enterobacteriaceae with a diversity of extended spectrum beta-lactamases encoding genes.

Título: Purified glycerin in balanced diets for chicken broilers from 8 to 21 days old / Glicerina purificada em dietas balanceadas para frangos de corte dos 8 aos 21 dias de idade
Fonte: Biosci. j. (Online);35(5):1515-1524, sept./oct. 2019. tab.
Idioma: en.
Resumo: This paper aimed to evaluate the metabolizability, performance and economic viability of purified glycerin inclusion in balanced diets fed to chicken broilers from 8 to 21 days old. Two experiments were conducted. In the first experiment, 100 broilers (14 days old) were distributed in a completely randomized design into two treatments, with five replications of 10 broilers. Treatments consisted of a control diet and a test diet, in which purified glycerin replaced 10% of the control diet. In the second experiment, 200 broilers (8 days old) were distributed in a completely randomized design into four treatments (0, 2, 4 and 6% of purified glycerin inclusion), with five replications of 10 broilers. The weight gain, feed intake, feed conversion, final weight, apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), metabolizability coefficients of dry matter (DMMC), crude protein (CPMC) and gross energy (GEMC), and the cost of feed per kg of broiler produced were evaluated. The AME, AMEn, DMMC, CPMC and GEMC from the purified glycerin were 3790 and 3560 kcal/kg, and 83.72, 71.52 and 86.27%, respectively. The glycerin levels did not affect (p>0.05) any of the performance characteristics (weight gain, feed intake, feed conversion and final weight). The lowest feeding cost and the highest gross margin were obtained for broilers fed with 6% purified glycerin. The inclusion of 6% purified glycerin in balanced diets for broilers from 8 to 21 days old was technically and economically feasible.

Objetivou-se neste trabalho avaliar a metabolizabilidade, o desempenho zootécnico e a viabilidade econômica da inclusão de glicerina purificada, em dietas balanceadas para frangos de corte dos 8 aos 21 dias de idade. Foram realizados dois experimentos, sendo que, no primeiro experimento, foram utilizados 100 pintos de 14 dias de idade, distribuídos em delineamento inteiramente casualizado (DIC), com dois tratamentos, cinco repetições de 10 aves. Os tratamentos consistiram de uma dieta referência e uma dieta teste, na qual a glicerina purificada substituiu 10% da dieta referência. No segundo experimento, foram utilizados 200 pintos de 8 dias de idade, distribuídos em delineamento experimental inteiramente casualizado (DIC), com quatro tratamentos (0, 2, 4 e 6% de inclusão de glicerina purificada) e cinco repetições de 10 aves. Foram determinados o ganho de peso, consumo de ração, conversão alimentar, peso final, energia metabolizável aparente (EMA), energia metabolizável aparente corrigida pelo balanço de nitrogênio (EMAn), os coeficientes de metabolizabilidade da matéria seca (CMMS), proteína bruta (CMPB), energia bruta (CMEB) e o custo da alimentação por kg de frango produzido. A EMA, EMAn e os CMMS, CMPB, CMEB da glicerina purificada obtida foram de 3790, 3560 Kcal/kg e 83,72, 71,52, 86,27%, respectivamente. Observou-se que a inclusão de glicerina purificada não afetou (p>0,05) o desempenho (ganho de peso, consumo de ração, conversão alimentar e peso final). O menor custo com a alimentação e a maior margem bruta foi obtido com os frangos alimentados com 6% de inclusão de glicerina purificada. A inclusão de 6% de glicerina purificada em dietas balanceadas para frangos de corte dos 8 aos 21 dias de idade, mostrou-se técnica e economicamente viável.

Resumo: En el presente estudio evaluamos indicadores entomológicos (índices de infección, colonización e infección natural) de ejemplares de Triatoma sordida capturados en el intra y peridomicilio de viviendas del Chaco Paraguayo en el período 2014 al 2016. El objetivo fue comparar con los hallazgos previamente reportados en el periodo 2010 al 2013 en la misma región. Además se ha incorporado la detección de fuente de alimentación como complemento para definir el riesgo de domiciliación de este vector secundario. Se aplicaron técnicas moleculares asociados a indicadores entomológicos y epidemiológicos a 220 ejemplares de T. sordida capturados en 67 viviendas de 24 localidades del Chaco. Se detectó infestación y colonización por T. sordida en el intradomicilio 13/67 (19%) y 5/13 (38%) y en el peridomicilio 54/67 (81%) y 43/54 (80%), respectivamente. Se detectó infección con T. cruzi en un 17,3% de los ejemplares analizados. La fuente de alimentación pudo detectarse en tan solo 13 de 220 ejemplares (6%), todos resultaron positivos para sangre de gallina y correspondían a captura en el peridomicilio. El índice de infestación intradomiciliar fue del 19%, superior al de años anteriores y similar a las zonas históricamente endémicas de la Región Occidental (18%-20%). El riesgo de transmisión intradomiciliar sigue siendo elevado porque en 3 de 5 viviendas con ninfas de T. sordida, los ejemplares estaban infectados con T. cruzi. Los indicadores entomológicos obtenidos en el presente estudio concuerdan con resultados previos de nuestro equipo, y confirman la capacidad vectorial de este triatomino secundario en la transmisión de la enfermedad de Chagas(AU)

Resumo: Specific microbiological parameters and the presence of Salmonella spp. were investigated in 72 chicken meat samples (36 wings and 36 drumsticks) collected from markets and butcher shops. The specific microbiological parameters were determined using a conventional cultural method and the presence of Salmonella spp. in chicken samples was determined using conventional and immunomagnetic separation (IMS)-polymerase chain reaction (PCR) methods. In addition, antimicrobial susceptibility of the isolates was revealed using the Kirby-Bauer disc diffusion method. The results indicated that 30 of the 72 samples were positive for Salmonella spp. by the conventional method, and 42 of the 72 were positive by the IMS-PCR method. However, 30 of the 72 samples were positive for Salmonella spp. by both methods. The Salmonella spp. isolates were confirmed by the VITEK2 Compact System and PCR. The susceptibilities of the isolates against 10 antibiotics were determined. The results indicated that isolates (27/30) showed the highest susceptibility to gentamycin (90.00%), while the highest resistance was to nalidixic acid and tetracycline at the 100 and 93.34% levels, respectively. These results indicate a high prevalence of Salmonella spp. in poultry meat from Erzurum city, Turkey, and the antimicrobial resistance profile of these isolates should be considered for public health. The results also show that the IMS-PCR technique was superior to the conventional method for detecting Salmonella in poultry meat.KEYWORDS:Chicken meat. Salmonella. IMS. PCR. Antimicrobial. INTRODUCTION Chicken is one of the most popular food products worldwide, because of nutritional, sensorial and economic factors. Chicken is widely consumed in homes and fast-food establishments, but can become contaminated during processing. The contamination of poultry products with Salmonella and other microorganismsis due to unhygienic conditions during the production, processing, distribution, marketing and preparationstages (DOOKERAN et al., 2012). The genus Salmonella includes short rod-shaped, facultative anaerobe, Gram-negative bacteria. Warm-blooded animals and humans are natural hosts for Salmonella spp. Detecting Salmonella spp. during production and before consumption is important to prevent food-borne salmonellosis. A Salmonella infection in humans is usually caused by consuming undercooked meat or other cross-contaminated foods, such as vegetables,milk and eggs (HASSANEIN et al., 2011). According to a report published by the Centres for Disease Control and Prevention (CDC), it is estimated that about 1.2 million people in the US have been exposed to Salmonella infections, and that an average of 23.000 hospitalisations and 450 deaths occur from these infections. The prevalence rates of Salmonella spp. in chicken meat sold in Turkey are 34-68.75%. Not only in Turkey, but in most developing countries, the absence of an epidemiological surveillance system for salmonellosis cases makes it difficult to effectively assess prevalence (KÄFERSTEIN, 2003). However, Received: 09/05/18 Accepted: 05/12/18

Parâmetros microbiológicos específicos e a presença de Salmonella spp. foram investigados em 72 amostras de carne de frango (36 asas e 36 baquetas) coletadas em mercados e açougues. Os parâmetros microbiológicos específicos foram determinados utilizando um método cultural convencional e a presença de Salmonella spp. em amostras de frango foi determinada utilizando métodos de reação em cadeia da polimerase (PCR) por separação convencional e imunomagnética (IMS). Além disso, a suscetibilidade antimicrobiana dos isolados foi revelada pelo método de difusão do disco de Kirby-Bauer. Os resultadosindicaram que 30 das 72 amostras foram positivas para Salmonella spp. pelo método convencional, e 42 das 72 foram positivas pelo método IMS-PCR. No entanto, 30 das 72 amostras foram positivas para Salmonella spp. por ambos os métodos. Os isolados de Salmonella spp. foram confirmados pelo sistema VITEK2 Compact e PCR. As susceptibilidades dos isolados a 10 antibióticos foram determinadas. Os resultados indicaram que os isolados (27/30) apresentaram maior suscetibilidade à gentamicina (90,00%), enquanto a maior resistência foi ao ácido nalidíxico e à tetraciclina nos níveis de 100 e 93,34%, respectivamente. Estes resultados indicam uma alta prevalência de Salmonella spp. em carne de frango da cidade de Erzurum, Turquia, e o perfil de resistência antimicrobiana desses isolados deve ser considerado para a saúde pública. Os resultados também demonstram que a técnica de IMS-PCR foi superior ao método convencional para detecção de Salmonella em carne de frango.

Resumo: In this work, the morphological features of liver in Chinese Taihe black-bone silky Fowl (BSF) were analyzed by light microscope and transmission electron microscopy. The results showed that two kinds of hepatocytes were present in Taihe BSF liver, i.e., the dark and the light hepatocyte. The dark hepatocyte was electron-dense and lager, with many organelles, mitochondria especially. The light hepatocytes were smaller than the dark. They had electron-lucent cytoplasm with a small number of organelles. Furthermore, there were lipolysosomes in the light hepatocyte. The numerous long and serried finger-like microvilli spread into bile canaliculus lumen. The glycogen granules intensely stained, spread in some hepatocytes. Numerous glycogen granules scattered in cytoplasm especially near bile canaliculi. However, lipid droplets were not observed in any hepatocytes. The natural apoptotic hepatocytes were observed in Taihe BSF liver. The hepatocytes which contain abundant uesicae-like endoplasmic reticulum closed the apoptotic hepatocytes and spread the process to approach the cell residual bodies. Besides, there was a macrophage with several phagosomes. In conclusion, the dark and the light hepatocyte were present in Chinese Taihe BSF liver. They were different from electron-dense and organelles. The hepatocytes of Taihe BSF could undergo natural apoptosis, regeneration and renew ability.

Fueron analizadas las características morfológicas ultraestructurales de hígado en la gallina sedosa china de hueso negro por microscopía óptica y microscopía electrónica de transmisión. Los resultados mostraron que se encontraron hepatocitos claros y oscuros en el hígado de la gallina china Taihe. El hepatocito oscuro era denso y de mayor tamaño. Tenía numerosos organelos, especialmente mitocondrias. Los hepatocitos claros eran más pequeños que los oscuros. El citoplasma presentó un pequeño número de organelos. Además, había lipolisosomas en los hepatocitos claros. Numerosas microvellosidades se extendían hacia los canalículos biliares. En algunos hepatocitos se observó una tinción marcada en los gránulos de glucógeno. Sin embargo, no se observaron gotas de lípidos en los hepatocitos. Se observaron los hepatocitos apoptóticos naturales en el hígado de la gallina Silky Taihe. Aquellos hepatocitos que contenían abundante retículo endoplásmico, cerraban los hepatocitos apoptóticos y extendían el proceso de acercamiento a cuerpos residuales celulares. También hubo un macrófago con varios fagosomas. En conclusión, los hepatocitos claros y oscuros estaban presentes en el hígado de la gallina Taihe china. Estos diferían de electrones de alta densidad y organelos. Los hepatocitos de la gallina Taihe presentaron una apoptosis natural y capacidad de regeneración.

Resumo: ABSTRACT Nowadays consumers are more concerned about food quality as well as how food is produced. Moreover, consumer demand for more natural, nutritious, safer to eat, and environmentally sustainable food has drawn attention to alternative breeding systems, such as a free-range system. Hens' eggs represent a rich source of important nutrients, including lipids and carotenoids. A detailed characterization of the nutritional and lipid profile of free-range chicken eggs from family farms was carried out. The chemical composition of the free-range egg yolks confirmed the advantages of this farming system, as a relevant source of unsaturated fatty acids and carotenoids, functional compounds in the human diet. These findings can help improve income generation, food supplementation, and consolidation of the family farming system.

Resumo: The poultry farm of posture is an economic activity of great relevance to Brazil. Health aspects of flocks of laying chickens, such as the occurrence of infestations by parasites and poultry pests, influence significantly the productivity indicators. In this context, the control of synanthropic diptera is one of the challenges of the poultry farmers and professionals of this area. In Brazil, the control of flies in poultry environments is based mainly on the use of pesticides, while other alternatives are less frequent. Among the flies' species most regularly found in poultry farms are the Musca domestica, Chrysomya spp., Fannia spp., and others. This review aims at compiling the literature on the occurrence, impact on poultry systems, biology, epidemiology and control of the species of synanthropic flies considered important for the Brazilian poultry industry.(AU)

A avicultura de postura é uma atividade econômica de grande relevância para o Brasil. Aspectos sanitários dos plantéis de galinhas poedeiras, tais como infestações por parasitos e pragas avícolas, influenciam significativamente os indicadores de produtividade desse setor. Nesse contexto, o controle de dípteros sinantrópicos constitui um dos desafios de avicultores e profissionais da área. No Brasil, o controle de moscas em ambientes avícolas é baseado, sobretudo, no uso de pesticidas, ao passo que o uso de outras alternativas é menos recorrente. Entre as espécies de moscas mais frequentes em granjas avícolas de postura, destacam-se Musca domestica, Chrysomya spp., Fannia spp., entre outras. O objetivo desta revisão é realizar a compilação da literatura existente sobre a ocorrência, o impacto nos sistemas avícolas, a biologia, a epidemiologia e o controle das espécies de dípteros sinantrópicos consideradas importantes para a avicultura de postura brasileira.(AU)
