Abstract Staphylococcus spp. play an important role in the etiology of bovine mastitis. Staphylococcus aureus is considered the most relevant species due to the production of virulence factors such as slime, which is required for biofilm formation. This study aimed to evaluate biofilm production and its ...
ABSTRACT Most Escherichia coli strains live harmlessly in the intestines and rarely cause disease in healthy individuals. Nonetheless, a number of pathogenic strains can cause diarrhea or extraintestinal diseases both in healthy and immunocompromised individuals. Diarrheal illnesses are a severe public h...
ABSTRACT The spread of pandemic Staphylococcus aureus clones, mainly methicillin-resistant S. aureus (MRSA), must be kept under surveillance to assemble an accurate, local epidemiological analysis. In Ecuador, the prevalence of the USA300 Latin American variant clone (USA300-LV) is well known; however, t...
Abstract Objectives To evaluate the prevalence of some virulence genes among 510 clinical Enterococcus spp. isolates and to assess the association of those genes with the species, infection site, and patient group (inpatients/outpatients). Methods Adhesins genes (aggregation substances agg and asa1 of ...
Determinadas linhagens de Escherichia coli comportam-se como patógenos em gatos, causando doenças gastrointestinais e extraintestinais. Neste estudo, foram utilizadas 205 cepas de E. coli isoladas de amostras de fezes provenientes de 19 gatos diarreicos e de 21 gatos não diarreicos, e três amostras d...
