Multiresistance and virulence factors of Staphylococcus aureus isolated from pigs

ABSTRACT The emergence of livestock-associated methicillin-resistant Staphylococcus aureus strains (LA-MRSA) and the potential role pigs in evolution these has led to increased interest research microorganisms. However, this contributed a lack isolation characterization methicillin-susceptible S. (MSSA). In study, prevalence nursery finishing stages were analyzed. susceptibility profiles antibiotics, tolerance heavy metals, biofilm production isolates evaluated using phenotypic genotypic techniques. A total 1,250 colonies suggestive spp. isolated from 128 pigs, which 63.6% (n = 795) belonged microbial genus. Sixty-seven 34 animals (26.5%) confirmed as (8.4%). No resistant copper, zinc, or methicillin detected; however, all presented resistance profile at least three different classes antimicrobials 21 produced biofilms. These data are concern, they indicate need for surveillance use well reinforce importance studies on MSSA strains.
