Antibiotic resistance of Stenotrophomonas maltophilia strains isolated from captive snakes.

The minimum inhibitory concentrations (MICs) of 24 antibiotics were determined for 45 Stenotrophomonas maltophilia strains by the microdilution method at 37 and 30 degrees C (after 24 h and 48 h of incubation). The isolates were obtained from mouth swabs and pus of 116 captive snakes whereas the identical strains (based on PFGE) of the same origin were discarded. At 37 degrees C, the isolates showed a low frequency of resistance to levofloxacin (0 and 8.

Prevalence of Campylobacter jejuni and its resistance to antibiotics in poultry in the Czech Republic.

Thermotolerant Campylobacter spp., in particular Campylobacter jejuni, are among the most frequently identified pathogens, found to be causing human gastrointestinal infections in Europe, with the Czech Republic being no exception. The presented work aimed at assessing results of the first nationwide monitoring of prevalence and antibiotic resistance of Campylobacter spp.

A case of endocarditis caused by the yeast Pichia fabianii with biofilm production and developed in vitro resistance to azoles in the course of antifungal treatment.

Pichia fabianii, a yeast rarely causing human infections, was isolated from the blood of a patient with aortic valve endocarditis. The isolates were initially identified biochemically as Candida pelliculosa, but based on direct sequencing of the ITS2 region of rRNA, they were subsequently reidentified as P. fabianii.

Prevalence of genes encoding extracellular virulence factors among meticillin-resistant Staphylococcus aureus isolates from the University Hospital, Olomouc, Czech Republic.

A rather fast and complicated progression of an infection caused by some strains of Staphylococcus aureus could be associated with the expression and co-action of virulence factor complexes in these strains. This study screened the antibiotic susceptibility and prevalence of virulence markers in isolates of meticillin-resistant S. aureus (MRSA) obtained from patients hospitalized at the University Hospital in Olomouc, Czech Republic.

Stenotrophomonas maltophilia as a part of normal oral bacterial flora in captive snakes and its susceptibility to antibiotics.

Only little is known about normal oral bacterial flora in captive snakes containing Stenotrophomonas maltophilia. This microbe has been reported as a causative agent of numerous infections in reptiles. Therefore, the goal of the study was to detect its presence in the mouths of a significant number of healthy captive snakes and determining its susceptibility to antibiotics at 30 and 37 degrees C.
