  • Antibiotic Resistance and Molecular Typing of Pseudomonas Aeruginosa: Focus on Imipenem
    BJID 2002; 6 (February) 1 Antibiotic Resistance and Molecular Typing of Pseudomonas aeruginosa: Focus on Imipenem Ana Lúcia Peixoto de Freitas and Afonso Luis Barth Federal University of Rio Grande do Sul, Pharmacy School, Clinical Hospital of Porto Alegre, Cardiology Institute, Porto Alegre, RS; Catholic University of Pelotas, Pharmacy School, Pelotas, RS, Brazil Susceptibility tests by disk diffusion and by E-test and molecular typing by macrorestriction analysis were performed to determine the relatedness of Pseudomonas aeruginosa isolates from three distinct hospitals. The resistance profile of 124 isolates to 8 antimicrobial agents was determined in three different hospitals, in Porto Alegre, Brazil. Frequencies of susceptibility ranged from 43.9% for carbenicillin to 87.7% for ceftazidime. Cross-resistance data of imipenem-resistant isolates indicated that most (70%) were also resistant to carbenicillin, although 30% remained susceptible to ceftazidime and cefepime. In general, susceptibility profiles were not able to determine relatedness among isolates of P. aeruginosa. On the other hand, molecular typing by macrorestriction analysis demonstrated high discriminatory power and identified 66 strains among 72 isolates of P. aeruginosa. Imipenem-susceptible isolates were all different. However, identical clones of imipenem-resistant isolates were found in two of the hospitals, despite variable response to other antibiotics. No clustering of infection among the different medical centers was observed. In conclusion, clones of P. aeruginosa did not spread among the different hospitals in our city even though related isolates of imipenem- resistant P. aeruginosa were found. Key Words: Pseudomonas aeruginosa, antibiotic resistance, imipenem. Despite improvements in antibiotic therapy, However, nosocomial isolates may easily develop Pseudomonas aeruginosa remains as one of the most resistance to carbapenens due to reduced uptake of prominent Gram-negative bacteria causing hospital- the drug, which leads to outbreaks of multiresistant/ associated infections.

  • Mechanisms of Resistance to P-Lactam Antibiotics Amongst 1993
    J. Med. Microbiol. - Vol. 43 (1999, 30G309 0 1995 The Pathological Society of Great Britain and Ireland ANTI MICROBIAL AGENTS Mechanisms of resistance to p-lactam antibiotics amongst Pseudomonas aeruginosa isolates collected in the UK in 1993 H. Y. CHEN, ME1 YUAN and D. M. LIVERMORE Department of Medical Microbiology, The London Hospital Medical College, Turner Street, London El 2AD Summary. Antimicrobial resistance among 199 1 Pseudomonas aeruginosa isolates collected at 24 UK hospitals during late 1993 was surveyed. Three-hundred and seventy-two of the isolates were resistant, or had reduced susceptibility, to some or all of azlocillin, carbenicillin, ceftazidime, imipenem and meropenem, and the mechanisms underlying their behaviour were examined. Only 13 isolates produced secondary p-lactamases : six possessed PSE- 1 or PSE-4 enzymes and seven had novel OXA enzyme types. Those with PSE types were highly resistant to azlocillin and carbenicillin whereas those with OXA enzymes were less resistant to these penicillins. Chromosomal p-lactamase derepression was demonstrated in 54 isolates, most of which were resistant to ceftazidime and azlocillin although susceptible to carbenicillin and carbapenems. p-Lactamase-independent “ intrinsic” resistance occurred in 277 isolates and is believed to reflect some combination of impermeability and efflux. Two forms were seen : the classical type, present in 195 isolates, gave carbenicillin resistance (MIC > 128 mg/L) and reduced susceptibility to ciprofloxacin and to all p-lactam agents except imipenem; a novel variant, seen in 82 isolates, affected only azlocillin, ceftazidime and, to a small extent, meropenem. Resistance to imipenem was largely dissociated from that to other p-lactam agents, and probably reflected loss of D2 porin, whereas resistance to meropenem was mostly associated with intrinsic resistance to penicillins and cephalosporins.
