Phenotypic and genotypic characterization of Staphylococcus aureus isolated from pork sausage

The objective of this study was to characterize the genotype and phenotype S. aureus isolates from pork sausages. Fifty samples sausages were collected, counts coagulase-positive Staphylococcus made obtained identify species. In isolates, presence genes sea, seb, sec, sed surveyed, methicillin-resistance assessed production biofilm in Congo red agar, stainless steel, polyethylene, glass, casing tested. capacity formation after exposure sublethal stress. Of tested, 12% had superior what is permitted by legislation. isolated 44% samples. these, 54% only gene 32% sec sed, 73% classified as methicillin-resistant (MRSA). MRSA 62% 35% both found study. Regarding 68% considered formers. After undergoing stress, most former proceeded form non-biofilm responded a distinct manner. condition which stress greatly induced cold. Biofilm observed steel 71% 57% respectively. Thus, we importance implementing good manufacturing practices within industry control microbial contamination formation.
