Sensitivity patterns of coagulase-negative staphylococci from neonates.

Area of Science:

• Medical Microbiology
• Neonatal Medicine
• Infectious Disease

Background:

• Coagulase-negative staphylococci (CoNS) are significant pathogens in neonatal intensive care units.
• Antibiotic resistance patterns in CoNS can vary geographically and are influenced by local antimicrobial prescribing practices.
• Understanding these patterns is crucial for effective infection control and treatment in special care baby units.

Purpose of the Study:

• To compare the antibiotic sensitivity profiles of coagulase-negative staphylococci isolates from two special care baby units (SCBUs).
• To evaluate the impact of differing antibiotic policies on the antimicrobial resistance of CoNS in neonates.
• To identify the most effective antibiotic classes against CoNS in the studied neonatal populations.

Main Methods:

• Collection of coagulase-negative staphylococci isolates from neonates in two distinct SCBUs.
• Antimicrobial susceptibility testing against 18 different antibiotics.
• Comparison of sensitivity profiles between the two units based on their respective antibiotic policies.

Main Results:

• Significant differences in antibiotic sensitivity profiles were observed between the two SCBUs.
• Netilmicin was identified as the most potent aminoglycoside against the tested CoNS isolates.
• Cefamandole emerged as the most effective cephalosporin in terms of antimicrobial activity.

Conclusions:

• Local antibiotic policies significantly influence the antibiotic sensitivity patterns of coagulase-negative staphylococci in neonatal units.
• Netilmicin and cefamandole represent valuable therapeutic options for treating CoNS infections in neonates within these settings.
• Judicious antibiotic stewardship is essential to mitigate the development of antimicrobial resistance in vulnerable neonatal populations.
