Identified in Fecal and Avian Pathogenic (APEC) From Brazil.

Colisitin-associated resistance in bacteria of food producing animals has gained significant attention with the gene being linked with resistance. Recently, newer variants of have emerged with more than nine variants currently recognized. Reports of associated resistance in of poultry appear to be relatively limited, but its prevalence requires assessment since poultry is one of the most important and cheapest sources of the world's protein and the emergence of resistance could limit our ability to treat disease outbreaks.

Accuracy of PCR universal primer for methicillin-resistant Staphylococcus and comparison of different phenotypic screening assays.

Characterization of methicillin-resistant Staphylococcus (MRS) is a continuous challenge at diagnostic laboratories. The phenotypic methods present heterogeneous results and the occurrence of variants of mecA gene turned this goal even more challenging to achieve. The present study provided an accurate and highly discriminatory screening tool for MRS, improving its detection.

Impairments of mecA gene detection in bovine Staphylococcus spp.

Staphylococcus aureus antimicrobial resistance, especially to beta-lactams, favors treatment failures and its persistence in herd environment. This work aimed to develop a more specific primer for mecA gene detection based on the comparison of the conserved regions from distinct host origins and also investigated the presence of homologue mecA(LGA251) in bovine strains. A total of 43 Staphylococcus spp.
