| Abstract: | The aim of performed examinations was to isolate, identify and determine a drug susceptibility of fungi cultured from faecal specimens submitted for detection of Clostridium difficile in cases of antibiotic-associated diarrhoea (AAD). One hundred samples of diarrhoeic faeces were examined using routine bacteriological methods (isolation and identification of C. difficile), serological test (detection of C. difficile toxins A/B) and mycological methods (isolation, identification and drug susceptibility testing of fungi). Out of twenty seven specimens of diarrhoeic faeces fungal strains were isolated, in 20 samples C. difficile strain and/or C. difficile toxins A/B were detected, in 23 specimens fungal strains, C. difficile strains and/or toxins A/B of this species were present. The most active in vitro agent against cultured fungal strains was nystatin. In conclusion it can be stated, that fungal strains are responsible for some cases of antibiotic-associated diarrhoea. So, mycological diagnostics of faecal samples from patients with diarrhoea after antibiotic therapy is necessary. Cases of diarrhoea with mixed bacterial and fungal aetiology (C. difficile + yeast-like fungus) were observed. |
