Our study revealed presence that had not been previously described region, including lihan tick virus (Phenuiviridae family) wuhan 2 (Chuviridae family), expands...
SUMMARY The order Chiroptera is considered the second largest group of mammals in world, hosting important zoonotic virus and bacteria. Bartonella hemotropic mycoplasmas are bacteria that parasite different mammals’ species, including humans, causing clinical manifestations. present work aimed investigating occurrence assessing phylogenetic positioning spp. Mycoplasma neotropical bats sampled from Brazil. Between December 2015 April 2016, 325 blood and/or tissues samples were collected 162...
Neospora caninum is a protozoan parasite that presents worldwide distribution and mainly implicated as responsible for bovine abortion. Although the presence of birds in cattle-raising properties positively correlated to higher infection rates, very little has been described about role these animals parasite's life cycle. In sense, this work aimed investigate serological histological positivity different avian species sampled its natural habitat or captivity. No was observed 294 tested serum...
SUMMARY Neospora caninum causes economical impact in cattle-raising farms since it is implicated as the major cause of bovine abortions. Although infection by parasite has been widely described mammals, role birds its life-cycle still obscure. Therefore, this work aimed to evaluate N. different chicken models. Experimental infections were conducted 7-day-old chicks, laying hens and embryonated eggs, where samples analysed for burden, IgG antibodies lesions promoted. Chickens demonstrated an...
The rock pigeon (Columba livia) may serve as a reservoir for several pathogenic agents that can be transmitted to poultry, wildlife, domesticated pets, and/or humans via excreta, secretions, or dust from feathers. In addition, ingestion of infected pigeons by wild and domestic animals also transmit these agents. health status 126 free-living in an urban area was evaluated microbiologic culture Salmonella serologic testing the presence antibodies Toxoplasma gondii Newcastle disease virus...
Parvoviruses (family Parvoviridae) are small, single-stranded DNA viruses. Many parvoviral pathogens of medical, veterinary and ecological importance have been identified. In this study, we used high-throughput sequencing (HTS) to investigate the diversity parvoviruses infecting wild domestic animals in Brazil. We identified 21 parvovirus sequences (including twelve nearly complete genomes nine partial genomes) samples derived from rodents, bats, opossums, birds cattle Pernambuco, São Paulo,...
