چکیده

Staphylococcus hyicus isolates (n=207), including 150 exfolitative toxigenic and 57 non-toxigenic strains, were examined for their susceptibility to 13 antimicrobial agents by using the dehydrated 96-well MIC panel system. The frequency of their resistance to penicillin and ampicillin was 76.8% (159/207), followed by erythromycin (56%, 116/207), trimethoprim-sulfamethoxazole (28.5%, 59/207), chloramphenicol (24.2%, 50/207), kanamycin (19.8%, 41/207), and doxycycline (1.4%, 3/207). Resistance to chloramphenicol and trimethoprim-sulfamethoxazole was significantly higher in toxigenic strains than non-toxigenic strains (p<0.01), whereas kanamycin and erythromycin resistance was significantly higher in non-toxigenic strains (p<0.01 and <0.05, respectively). Resistance to two or more antimicrobials was observed in 85.5% (177/207) of total strains, with a significantly higher occurrence in toxigenic strains (89.3%, 134/150 vs. 75.4%, 43/57; p<0.05).

Development and evaluation of an indirect ELISA for detection of exfoliative toxin ExhA, ExhB or ExhC produced by Staphylococcus hyicus.

Immunoblot analysis and enzyme-linked immunosorbent assay (ELISA) confirmed previous reports that the Staphylococcus hyicus exfoliative toxins ExhA and ExhB are metalloproteins, and further indicated that ExhC is also a metalloprotein. An indirect ELISA was developed for the detection of toxigenic strains as an alternative method to the use of phage typing for selection of S. hyicus isolates to...

Production of exfoliative toxin by isolates of Staphylococcus hyicus from different countries.

A total of 218 isolates of Staphylococcus hyicus from pigs in eight countries (Belgium, Croatia, Germany, Japan, Korea, Slovenia, the uk and the usa) and 44 isolates from other animals in Belgium, India, Japan and the usa were examined for the genes encoding the exfoliative toxins ExhA, ExhB, ExhC and ExhD by multiplex pcr. The expression of the toxins was confirmed by immunoblot analysis, usin...

Distribution of the putative virulence factor encoding gene sheta in Staphylococcus hyicus strains of various origins

In the present study, Staphylococcus (S.) hyicus strains isolated in Russia (n = 23) and Germany (n = 17) were investigated for the prevalence of the previously described genes sheta and shetb. Sheta was detected in 16 S. hyicus strains. Sheta-positive strains were mainly found among strains isolated from exudative epidermitis, and frequently together with the exfoliative toxin-encoding genes e...

Antimicrobial susceptibilities of Clostridium difficile.

The antimicrobial susceptibilities of 78 strains of Clostridium difficile isolated from patients with and without gastrointestinal symptoms were determined and compared. Strains from patients with symptoms were more likely to show resistance to antibiotics. The antimicrobial susceptibilities of toxigenic and non-toxigenic strains were found to be similar.

Exudative epidermitis in pigs caused by toxigenic Staphylococcus chromogenes.

Staphylococcus chromogenes is closely related to Staphylococcus hyicus, which is recognised as the causative agent of exudative epidermitis (EE) in pigs. S. chromogenes is part of the normal skin flora of pigs, cattle and poultry and has so far been considered non-pathogenic to pigs. A strain of S. chromogenes producing exfoliative toxin type B, ExhB, was identified by the use of a multiplex PC...
