Klebsiella pneumoniae

klebsiella pneumoniae on desoxycholate citrate agar.jpg
Large (about 5 mm in diameter), lactose positive colonies of Klebsiella pneumoniae on desoxycholate-citrate agar. Cultivation 37°C, 24 hours.

Klebsiella pneumoniae is a common source of hospital-acquired infections. Some of the strains can carry plasmids that harbour genes conferring resistance to almost all antibiotics. These bacteria are called multiresistant or, informally, superbugs or super bacteria.

Among these bacteria many different Enterobacteriaceae species were identified, including Citrobacter freundii, Enterobacter cloacae, Escherichia coli, Klebsiella oxytoca, Morganella morganii, Proteus spp., Providencia spp.. Most isolates remain susceptible to colistin and tigecycline (natural resistance to colistin in M.morganii, Proteus spp. and Providencia spp. !!).
