Microbiological researches of the virulent species of Staphylococcus aureus in pathological abcesses at swines

Abstract

Current researches are important due to the frequency of cases caused by some pathologies of abscesses recorded at pigs slaughtered in slaughterhouse conditions. In this context, samples from various internal abscesses of slaughtered pigs and the assessment of virulence and incidence of identified bacterial microflora species were studied. Microbiological researches on abscesses of different origins at slaughtered pigs has demonstrated the presence of the important bacterial microflora consisting of species of Staphylococcus aureus in all cases of microbiological laboratory investigation. S.aureus strains isolated from various sources of pathological abscesses at slaughtered pigs in slaughterhouse conditions expressed a higher proportion of quantitative bacterioscopic and bacteriological microbiological values in heart abscesses, followed by samples invaded with staphylococci in the chest, leg, jaw and so on. The Staphylococcus aureus strain expressed high virulence factors sampled by a phenotypic mechanism, and it was found that this strain showed the gene encoding the collagen binding protein and at the same time mediates the binding of Staphylococcus aureus to fibrinogen.
