Isolation and genetic characterization of from chickens from public markets in Pernambuco State, Brazil.

This study aimed to evaluate the presence and viability of in chickens intended for human consumption in the Pernambuco State, Brazil. Blood and tissue samples were collected from 25 chickens sold in markets in Recife, Pernambuco. Samples were evaluated by indirect immunofluorescence assay (IFA) to detect antibodies to .

An abortion storm in a goat farm in the Northeast Region of Brazil was caused by the atypical genotype #13.

The objective of this study was to characterise a -induced abortion outbreak on a goat farm in the State of Paraíba, Northeast Region of Brazil. From a herd of 10 does, seven experienced abortions and one gave birth to twins (one stillborn and the other weak and underdeveloped). Serum samples from all of the does were analysed by indirect fluorescent antibody test (IFAT).

Genetic diversity of in goats and sheep from the Northeast Region of Brazil destined for human consumption.

This study aimed to genotype isolates of obtained from samples of brain, diaphragm and heart of goats and sheep intended for human consumption in the State of Paraíba, Brazil. Tissue samples from 14 animals, goats ( = 5) and lambs ( = 9), were sourced from public slaughterhouses in seven cities and bio-assayed in mice. The brains of the mice were utilized for DNA extraction.

Genetic characterisation of in dairy cattle and calves during the early stages of a calving season.

is a causative agent of cryptosporidiosis, an infectious gastroenteritis in neonatal ruminants, which can be fatal in severe cases. The aim of this study was to determine the prevalence of infections in dairy cattle/calves during the early stages of a calving season and the species/genotypes of the present. Faecal samples collected from pre- and post-partum dams ( = 224) as well as calves from age ∼1 day onwards ( = 312) were examined.
