| A topographical and histological study of the male genital accessory gland complex of Boophilus microplus was undertaken. Ten lobes were found, the most prominent of which is the single dorso-median lobe, subdivided into antero-dorsal and postero-dorsal lobes. The other lobes are: a pair of postero-ventral lobes, a pair of lateral lobes (subdivided into dorso-lateral and postero-lateral lobes), a pair of antero-ventral lobes, a single medio-ventral lobe and a pair of latero-ventral lobes. These lobes were observed to present individual topographical and histological characteristics, with independent openings, hence the conclusion is that they form a gland complex. The secretory nature of the dorso-median lobe duct was also analysed. |

| The structural analysis of oviducts in Boophilus microplus (Canestrini, 1887) in different stages of ingurgitation has indicated that they are constituted primarily of an internal cylinder and an external cylinder with different cell types being found between them. Copulated females in active ingurgitation process show typical variations along the internal cylinder, and three regions can be defined: anterior, ring-like and transitional. Based on such regionalization, hypotheses were raised about where and how fertilization takes place, a process yet to be clarified for the acari. |

| Abstract Borreliosis caused by Borrelia burgdorferi sensu lato is a cosmopolitan zoonosis studied worldwide; it is called Lyme disease in many countries of the Northern Hemisphere and Lyme-like or Baggio-Yoshinari Syndrome in Brazil. However, despite the increasing number of suspect cases, this disease is still neglected in Brazil by the medical and veterinary communities. Brazilian Lyme-like borreliosis likely involves capybaras as reservoirs and Amblyomma and Rhipicephalus ticks as vectors. Thus, domestic animals can serve as key carriers in pathogen dissemination. This zoonosis has been little studied in horses in Brazil. The first survey was performed in the state of Rio de Janeiro, and this Brazilian Borreliosis exhibits many differences from the... |

| Ehrlichiosis is a worldwide distributed disease caused by different bacteria of the Ehrlichia genus that are transmitted by arthropod vectors. Its occurrence in dogs is considered endemic in several regions of Brazil. Regarding cats, however, few studies have been done and, consequently, there is not enough data available. In order to detect Ehrlichia spp. in cats from the central-western region of Brazil, blood and serum samples were collected from a regional population of 212 individuals originated from the cities of Cuiabá and Várzea Grande. These animals were tested by the Immunofluorescence Assay (IFA) and the Polymerase Chain Reaction (PCR) designed to amplify a 409 bp fragment of the dsb gene. The results obtained show that 88 (41.5%) cats were... |

| The aim of this study was to investigate the presence of DNA of Borrelia burgdorferi sensu lato (s.l.) in ticks that feed on horses used for animal traction in rural Jataizinho, Parana, Brazil. Between February and June 2008, a total of 224 ticks was collected of which 75% were identified as Dermacentor nitens and 25% as Amblyomma cajenense. To amplify B. burgdorferi s.l. DNA, the intergenic space region (ISR) between the 5S (rrf) 23S (rrl) rRNA genes was used as targets for nested-PCR. Two ticks of the D. nitens species were positive for B. burgdorferi s.l. Both species showed a fragment of 184 bp, but the sequencing revealed 99.9% homology with the B. burgdorferi sensu stricto (s.s.) strain B31. These results showed, for the first time, the presence of... |

| ABSTRACT: From May to September 2011, a total of 138 wild rodents of the Cricetidae family were collected in the cities of Anhembi, Bofete and Torre de Pedra, in São Paulo State. All animals were examined for the presence of ticks, which were collected and identified at species level in the laboratory by morphological examination (for adults, nymphs and larvae) and molecular biology, by sequencing of a fragment of the 16S mitochondrial rDNA (for larvae). A total of 47 ticks (21 larvae and 26 nymphs) were collected from rodents, identified as 21 larvae and 23 nymphs of Amblyomma ovale (collected on Oligoryzomys nigripes , Oligoryzomys flavescens , Sooretamys agouya and Nectomys squamipes ), two nymphs of Ixodes schulzei (O. nigripes and O. flavescens ) and... |

| ABSTRACT: Ticks are arthropods that are highly competent in transmitting pathogens to animals and humans. Among these, the genus Amblyomma is the most representative within the Neotropics. Amblyomma longirostre ticks are naturally distributed in countries of South, Central and North America. Their immature stages preferentially parasitize birds (Passeriformes), while adult stages are usually found on rodents. Therefore, reports of this tick species on wild hosts is epidemiologically relevant, especially because of these ticks' potential for transmitting pathogens to other wild and domestic animals, and also to humans. Thus, the aim of this study was to report infestation by Amblyomma longirostre on Cyanocompsa brissonii in southern Brazil. |

| ABSTRACT: The aim of this study was to investigate exposure of Baixadeiro horses to Rickettsia spp. and to ticks infected by Rickettsia in the Baixada Maranhense (lowlands) micro-region, state of Maranhão. A total of 258 horses were tested for Rickettsia rickettsii, Rickettsia amblyommatis and Rickettsia bellii using the immunofluorescence assay (IFA). Overall, 58.91% (152/258) of the horses were seroreactive for at least one Rickettsia species, and 85.27% of the horses were infested with one or more species of tick, which were identified as Dermacentor nitens (93.63%), Amblyomma cajennense sensu stricto (4.55%) and Rhipicephalus (Boophilus) microplus (1.82%). These ticks were subjected to DNA extraction and were tested using the polymerase chain reaction... |

| Nos últimos anos, a Embrapa Gado de Corte tem recebido inúmeras indagações por carta, telefone, em palestras etc. sobre a utilização do alho, em especial, no controle da mosca-dos- chifres (Haematobia irritans irritans) em bovinos. O principal objetivo do experimento foi verificar a eficácia do alho em pó, adicionado ao sal mineral, no controle de mosca-dos-chifres, carrapatos (Boophilus microplus) e helmintos de bovinos. Foram utilizados 42 novilhos cruzados, distribuídos em dois grupos de 21 animais, levando-se em consideração a raça, o peso, ovos por grama de fezes (OPH), numero de moscas, idade e o numero de carrapatos. Durante todo o período experimental, os grupos ficaram em piquetes separados com pastagens de Brachiaria decumbens. Um grupo de... |

| Os carrapatos são artrópodes hematófagos que parasitam muitas espécies de hospedeiros, desde mamíferos até anfíbios, e podem ser encontrados em vários ambientes nas diversas regiões do planeta. O tema ?Carrapatos no Brasil? tem importância, tanto na saúde animal quanto ao aspecto econômico. Os prejuízos, apenas no que tange a cadeia produtiva de bovinos no país, são estimados em 3,2 bilhões de dólares ao ano. Com respeito à saúde pública a bactéria Rickettsia rickettsii, agente da febre maculosa brasileira (FMB), tem os carrapatos por vetores. Contudo, os prejuízos relativos à manutenção da saúde pública não foram ainda estimados, e são incalculáveis quando se trata de perdas de vidas humanas. O Museu do Carrapato tem por objetivo apresentar, de forma... |

| 0 controle efetivo da dermatobiose pode ser feito por meio de dois tipos de tratamentos: estratégico e tático. Como foi visto, dois fatores são considerados importantes na exacerbação da D. hominis \te seus veiculadores, a temperatura e a umidade. Em nossa região, a temperatura inicia o seu limiar favorável a biologia dos insetos logo após o inverno, quando começa a se elevar. Na mesma época, reiniciam-se as precipitações pluviais, condicionando a atmosfera com alto teor de umidade. É fim de setembro e inicio da primavera, período em que acontece a eclosão dos insetos. Nessa época, como os dados experimentalmente obtidos indicam, acontecem as maiores infestações de berne (setembro e outubro). Devido a tal condição, sugere-se o tratamento estratégico de... |
