The resistance patterns and serotypes of Pseudomonas aeruginosa strains isolated from children

Abstract

Among 916 Psedomfmonas aeruginosa strains isolated from children in a Warsaw hospital during the period 1985–1988 the most frequently encountercd serotypes were O6.O11, O12, and O16. The majority of isolates resistant to aminoglycosides were characterized by simultaneous registance to gentamicin and tobramycin and belonged to serotype O11. Among isolates resistant to β-lactam antibiotics the most frequently encountered serotype was O6, followed by serotyp O3 and O11. Most strains of serotype O12 were resistant to aminoglycosidcs and β-lactam antibiotics as has been reported from other countries.
