The microbiological diagnosis is carried out via the transfer within respective specimens and the biochemical identification.
Klebsiella are inherently resistant to penicillin G (PENICILLIN G et al) and ampicillin (BINOTAL et al). Cause of natural resistance are beta-lactamases that are largely inhibited by beta-lactamase inhibitors. According to the resistance study the Paul Ehrlich Society for Chemotherapy 5-10% of the strains to fluoroquinolones and 10-15% of strains to cotrimoxazole (BACTRIM et al) are resistant. the spread of ESBL-producing strains is as critical (extended-spectrum beta-lactamases) which bring about resistance to broadly effective cephalosporins [cefotaxime (Claforan et al), ceftazidime (FORTUM et al)], considered. In 2004, the proportion was 7.3% in Klebsiella oxytoca and 12.4% for Klebsiella oxytoca in the middle. In addition, about 20% of the strains of Klebsiella oxytoca against piperacillin (PIPRIL among others) in combination with a beta-lactamase inhibitor are resistant.
