Resumo: During an ecological study, carried out between 1994 and 1996 with Streptoprocne biscutata (Sclater) (Apodiformes: Apodidae) birds, that inhabit caves in the Quatro Barras County, State of Paraná, Southern Brazil, a new tick species of the subgenus Multidentatus was observed. The female, male, nymph, and larva of Ixodes (Multidentatus) paranaensis n. sp., are described. Of the 12 known species of the subgenus Multidentatus, only I. (M.) auritulus Neumann, 1904 and I. (M.) murreleti Cooley and Kohls, 1945 occur in the Neartic region and only I. (M.) auritulus occurs in the Neotropical region. As such, I. (M.) paranaensis n. sp. increases the number of species and the distribution area of the subgenus Multidentatus in the Americas

Título: Ixodes (Haemixodes) longiscutatum Boero (new status) and I. (H.) uruguayensis Kohls & Clifford, a new synonym of I. (H.) longiscutatum (Acari: Ixodidae)
Fonte: Mem. Inst. Oswaldo Cruz;96(8):1121-1122, Nov. 2001.
Idioma: en.
Resumo: Females of Ixodes (Haemixodes) uruguayensis Kohls & Clifford, 1967, a species whose adults were unknown until the present, were obtained in the laboratory from engorged nymphs collected on rodents (Scapteromys tumidus and Oxymycterus nasutus) in the counties of Maldonado and San José, Uruguay. Morphological characters of these females were identical to those given in the description of the female of Ixodes longiscutatum Boero, 1944. I. uruguayensis is, thus, relegated to a junior subjective synonym of I. longiscutatum. However, because of the unique morphological characters of the immature stages, the validity of the subgenus Haemixodes Kohls & Clifford, 1967 is not questioned. Therefore, the new status of Ixodes (Haemixodes) uruguayensis Kohls & Clifford, 1967 is Ixodes (Haemixodes) longiscutatum Boero, 1944

Título: Oviposition and eclosion periods of Ixodes didelphidis Fonseca and Aragäo, 1951 (Acari: Ixodidae) under laboratory conditions
Fonte: Mem. Inst. Oswaldo Cruz;95(6):905-8, Nov.-Dec. 2000. tab.
Idioma: en.
Resumo: Oviposition and eclosion periods for Ixodes didelphidis were observed under two temperatures (25o.C and 27o.C) and 90-95 percent humidity. Although there was a significant increase in the eclosion period (p<0.05) and a tendency to increase the oviposition period at 25o.C, there was neither significant differences in the interval (days), until maximum peak of eclosion nor in the number of emerging larvae during the peak nor the total number of emerged larvae. These temperature values are not critical for embryological development of the species. Because at 27o.C and under high humidity the oviposition and eclosion periods are shorter, and the percentage of emerged larvae is higher, we consider this to be the ideal temperature for laboratory studies

Título: Detection of a Rickettsia genotype related to the old world infecting Amblyomma sculptum tick in an endemic area of brazilian spotted fever
Fonte: Rev. patol. trop;48(3):161-169, 2019. tab.
Idioma: en.
Resumo: Brazilian Spotted Fever is an important tick-borne disease caused by Rickettsia rickettsii and transmitted mainly by the human-biting tick Amblyomma sculptum. During an epidemiological surveillance in Pedro Leopoldo, an endemic area of Minas Gerais State, southeastern Brazil, ectoparasites were collected from vertebrate hosts and from the environment. Rickettsial genes were obtained from a male A. sculptum and the resulting phylogenetic tree grouped this bacterium with Rickettsia sp. isolate Pampulha, a strain closely related to the pathogenic species Rickettsia tamurae and Rickettsia monacensis. This is the first report of sequences phylogenetically related to R. tamurae and R. monacensis infecting A. sculptum in Brazil.

Idioma: en.
Resumo: Equine granulocytic anaplasmosis is caused by Anaplasma phagocytophilum, a gram negative, obligatory intracellular bacterium, member of Anaplasmataceae family, included in the Rickettsiales order. Little is known about the disease, transmission dynamics, genetic diversity and prevalence in Minas Gerais state, Brazil. This work aimed to do a serosurvey using indirect immunofluorescent assay (IFA) test and evaluation of buffy coat smears, and nested polymerase chain reaction (PCR) as diagnostic methods, to determine the disease situation in horses from two manga-larga marchador breeding farms located in the municipalities of Ataléia e São Vicente de Minas, in Minas Gerais state. It was found that 76% (131/172) of the animals were considered reactive for IFA test, and the total of 12.8% was positive at buffy coat smears analysis. At PCR analysis, it was found 1.94% of the samples positive to the infection. Those samples were sequenced and showed 96% of similarity to A. phagocytophilum from a Ixodes ricinus tick. There is a high frequency of animals with the evidence of contact to A. phagocytophilum on the two evaluated properties in this study, which was proved by positiveness in PCR analysis. New researches must be carried out to better understand the epidemiologic and clinical dynamic of the disease in the state of Minas Gerais.(AU)

A anaplasmose granulocítica equina é causada por uma bactéria gram-negativa, intracelular obrigatória, membro da família Anaplasmataceae, incluída na ordem Rickettsiales e denominada de Anaplasma phagocytophilum. Pouco se sabe sobre a doença, sua dinâmica de transmissão, diversidade genética e prevalência em Minas Gerais, Brasil. Este trabalho teve por objetivo realizar o levantamento sorológico utilizando a reação de imunofluorescência indireta, avaliação direta de capa leucocitária e nested reação em cadeia da polimerase (PCR) como métodos diagnósticos, a fim de avaliar a situação da doença em dois haras de criação de cavalos manga-larga marchador localizados nas cidades de Ataléia e São Vicente de Minas, no estado de Minas Gerais. Foi encontrada prevalência de 76% (131/172) de animais reativos para a reação de imunofluorescência indireta, quando todos os animais das duas propriedades e das duas coletas foram agrupados, e 12,8% dos animais foram positivos na avaliação da capa leucocitária. A reação de imunofluorescência indireta detectou 1,94% das amostras como positivas para o agente. Essas amostras foram submetidas ao sequenciamento de nucleotídeos, e foi observada similaridade de 96% com A. phagocytophilum proveniente de carrapatos Ixodes ricinus. Existe alta prevalência de animais positivos para a infecção por A. phagocytophilum, o que foi provado pela positividade dos animais à PCR. Novas pesquisas devem ser conduzidas a fim de entender a dinâmica epidemiológica e clínica da doença no estado de Minas Gerais.(AU)

Título: Especies de garrapatas duras en un área urbana protegida de la Ciudad Autónoma de Buenos Aires / Hard Tick Species in a Protected Urban Area of Buenos Aires City
Fonte: Rev. argent. salud publica;8(32):7-12, Sept. 2017. graf.
Idioma: es.
Resumo: INTRODUCCIÓN: Las garrapatas (Acari, Ixodida) son artrópodos vectores de gran diversidad de patógenos virales, bacterianos y protozoarios, muchos de los cuales son zoonóticos y emergentes. En Argentina se encuentran numerosas especies de garrapatas duras (familia Ixodidae) que también parasitan al hombre. Las áreas urbanas protegidas son ecosistemas naturales que están dentro de grandes urbes o limitan con ellas. En la Reserva Ecológica Costanera Sur (RECS) de la Ciudad Autónoma de Buenos Aires (CABA) circulan especies silvestres que no tienen presencia en otras áreas de la ciudad, con potenciales hospedadores y vectores. OBJETIVOS: Determinar las especies de garrapatas presentes en la RECS (CABA). MÉTODOS: Se realizó un estudio cuantitativo descriptivo transversal mediante muestreos para colectar garrapatas de vegetación y de hospedadores como perros y distintas especies de roedores. RESULTADOS: En total se recolectaron 1090 garrapatas de la vegetación (454 de la especie Amblyomma aureolatum, 635 Ixodes auritulus y 1 Amblyomma triste) y 67 de los perros (64 A. aureolatum, 2 Rhipicephalus sanguineus sensu lato y 1 A. triste). No se detectaron garrapatas en 200 roedores revisados. CONCLUSIONES: Las especies de garrapatas detectadas en este estudio tienen importancia en salud pública, tanto porque parasitan a humanos (A. aureolatum, A. triste y R. sanguineus s. l.) como porque participan en el ciclo y transmisión de distintos patógenos zoonóticos en distintas regiones del mundo, incluso Argentina.

INTRODUCTION: Ticks (Acari, Ixodida) are arthropod vectors of great diversity of viral, bacterial and protozoan pathogens, many of which are zoonotic and emerging. In Argentina, there are numerous hard tick species (Ixodidae family) which also parasitize humans. Protected urban areas are natural ecosystems located within or near large urban centers. The Costanera Sur Ecological Reserve (RECS) of Buenos Aires city shows a circulation of wild species that have no presence in other areas of the city. There are potential hosts and vectors. OBJECTIVES: A quantitative cross sectional study was carried to detect the species of ticks present in the RECS of Buenos Aires city. METHODS: A quantitative cross - sectional study was carried out by sampling to collect ticks from vegetation and hosts (rodents and dogs). RESULTS: In total, 1090 ticks were collected from the vegetation (454 of the species Amblyomma aureolatum, 635 Ixodes auritulus and 1 Amblyomma triste) and 67 from dogs (64 A. aureolatum, 2 Rhipicephalus sanguineus sensu lato and 1 A. triste). No ticks were detected in 200 examined rodents. CONCLUSIONS: Ticks species detected in this study are important for public health, because they are parasites of humans (A. aureolatum, A. triste and R. sanguineus s. l.) and participate in the cycle and transmission of different zoonotic pathogens in different regions of the world, including Argentina.

Título: Seroprevalence of Borrelia burgdorferi in occupationally exposed persons in the Belgrade area, Serbia
Fonte: Braz. j. microbiol;46(3):807-814, July-Sept. 2015. tab, ilus.
Idioma: en.
Resumo:

Lyme disease (LD) is a natural focal zoonotic disease caused by Borrelia burgdorferi, which is mainly transmitted through infected Ixodes ricinus tick bites. The presence and abundance of ticks in various habitats, the infectivity rate, as well as prolonged human exposure to ticks are factors that may affect the infection risk as well as the incidence of LD. In recent years, 20% to 25% of ticks infected with different borrelial species, as well as about 5,300 citizens with LD, have been registered in the Belgrade area. Many of the patients reported tick bites in city’s grassy areas. The aim of this study was to assess the seroprevalence of B. burgdorferi in high-risk groups (forestry workers and soldiers) in the Belgrade area, and to compare the results with healthy blood donors. A two-step algorithm consisting of ELISA and Western blot tests was used in the study. Immunoreactivity profiles were also compared between the groups. The results obtained showed the seroprevalence to be 11.76% in the group of forestry workers, 17.14% in the group of soldiers infected by tick bites and 8.57% in the population of healthy blood donors. The highest IgM reactivity was detected against the OspC protein, while IgG antibodies showed high reactivity against VlsE, p19, p41, OspC, OspA and p17. Further investigations in this field are necessary in humans and animals in order to improve protective and preventive measures against LD.

Idioma: es.
Resumo: Objetivo: teniendo en cuenta el riesgo potencial que para Cuba constituye la presencia del agente trasmisor, los autores consideran importante la revisión del tema con vistas a una actualización de los especialistas y demás entidades del sistema de salud que puedan intervenir en la vigilancia y control epidemiológico de esta enfermedad. Desarrollo: se comenta la historia de la enfermedad, la microbiología, la epizootiología y la epidemiología, así como las manifestaciones clínicas en los principales animales domésticos. Conclusiones: la borreliosis de Lyme es una nueva enfermedad infecciosa; comparte como otras borrelias y espiroquetas su afinidad por el sistema nervioso central y el sistema nervioso periférico, y se convierte en un diagnóstico de exclusión optimista en Neurología. Conocer sus vectores, su distribución geográfica y algunas de las características biológicas específicas de esta nueva especie de borrelia es de suma importancia para el médico práctico de este nuevo siglo, donde la inmunología y la biología molecular iluminan el oscuro camino de viejas y nuevas interrogantes

Objective: bearing in mind the risk posed by the presence of the vector of Lyme disease in Cuba, the authors have considered it necessary to carry out a review of the disease with the purpose of contributing updated information to specialists and health institutions involved in its surveillance and epidemiological control. Content: a discussion is presented of the history, microbiology, epizootiology and epidemiology of Lyme disease, as well as its clinical manifestations in the main domestic animal hosts. Conclusions: Lyme borreliosis is a new infectious disease. Like other borrelias and spirochetes, it has an affinity for the central nervous system and the peripheral nervous system, thus becoming a diagnosis of optimistic exclusion in neurology. Knowledge about the vectors, geographic distribution and some specific biological characteristics of this new borrelia species is crucial for practitioners of the 21st century, a time when immunology and molecular biology shed new light on old and new questions alike
