Klebsiella pneumoniae is an opportunistic bacteria that causesNosocomial infections (contracted in a hospital environment) such as cystitis, pneumonia and septicemia.

Klebsiella pneumoniae and its resistance to antibiotics

Klebsiella pneumoniae is naturally resistant to penicillins thanks to a uncomfortable chromosome. In addition, multiresistance has been observed among its strains. Some bacilli produce ESBL (beta-lactamases to spectrum extended), conferring resistance to beta-lactams.

In Europe, the frequency of bacteria Klesiella pneumoniae resistant to fluoroquinolones, to the cephalosporins third generation and aminoglycosides increased.

To treat infections involving multi-resistant bacteria, carbapenems may be used as a last resort. Cases of bacteria K. pneumoniae resistant to carbapenems have also been noted.
