Molecular detection of Brucella abortus in wild and captive felids.

Purpose: Brucellosis is a zoonotic disease of great public health importance. In wild animals, Brucella abortus is one of the most diagnosed species, mainly in enzootic environments where domestic animals share the same environment. B.

Quantitative qPCR Analysis of Ruminal Microorganisms in Beef Cattle Grazing in Pastures in the Rainy Season and Supplemented with Different Protein Levels.

We tested the hypothesis that supplementation with three protein levels improves fermentation parameters without changing the rumen microbial population of grazing beef cattle in the rainy season. Four rumen-cannulated Nellore bulls (432 ± 21 kg of body weight) were used in a 4 × 4 Latin square design with four supplements and four experimental periods of 21 days each. The treatments were mineral supplement (ad libitum) and supplements with low, medium (MPS), and high protein supplement (HPS), supplying 106, 408, and 601 g/day of CP, respectively.

Occurrence of toxin genes in Staphylococcus pseudintermedius from diseased dogs and other domestic and wild species.

Introduction: Staphylococcus pseudintermedius is coagulase-positive species of the Staphylococcus intermedius group. It is an opportunistic pathogen that can cause infection in various parts of the body and has a zoonotic potential. Although studies on the pathogenicity and epidemiology of S.

Presence of Ureaplasma diversum in the genital tracts of female dairy cattle in Mato Grosso State, Brazil.

Ureaplasma diversum infection in bovine females may result in various reproductive problems, including granular vulvovaginitis, abortion, weak calves, salpingitis, and spontaneous abortion. The presence of U. diversum in a dairy bovine population from midwestern Brazil has not been established.

Molecular assessment of the transplacental transmission of Toxoplasma gondii, Neospora caninum, Brucella canis and Ehrlichia canis in dogs.

Given the fact that numerous microbial species can be detected in pregnant female dogs, the objective of this study was to assess the transplacental transmission of Brucella canis, Ehrlichia canis, Neospora caninum and Toxoplasma gondii in stillborn puppies. This study involved 41 stillborn puppies, 78.6% of which were positive for T.
