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...

ABSTRACT: The municipality of Ji-Paraná, Rondônia, is one of the major dairy production areas in the north region of Brazil. Thus, it is important to evaluate infectious agents that have the potential to negatively affect productivity in the industry. The objective of this study was to investigate the prevalence of ' Candidatus Mycoplasma haemobos' by using a PCR-based detection method and correlate this with dairy herd variables (abortion frequency, weak calf birth rate, total cattle number, &gt;24-month-old cow number, farm size, and production system) in family farms of the Ji-Paraná municipality, north region, Brazil. Blood samples were collected from 320 dairy cows located across 64 farms (i.e., five animals per farm) from September 2012 to November...
