Antibiotic Sensitivity and Clinico- epidemiological Profile of Staphylococcal Infections

Area of Science:

• Microbiology
• Infectious Diseases
• Pediatrics

Background:

• Staphylococcus aureus (S. aureus) is a common cause of pediatric infections.
• Antibiotic resistance in S. aureus is a growing global health threat.
• Understanding local resistance patterns is crucial for effective treatment.

Purpose of the Study:

• To determine the antibiotic sensitivity profile of S. aureus isolates from admitted children.
• To identify the prevalence of methicillin-resistant S. aureus (MRSA) in this pediatric population.
• To assess resistance rates to clindamycin in both methicillin-sensitive and methicillin-resistant S. aureus strains.

Main Methods:

• A hospital-based study was conducted on 66 S. aureus isolates from pediatric patients (age 0-18 years).
• Isolates were collected from a tertiary hospital in Kolkata, India.
• Antibiotic sensitivity testing was performed, with a focus on methicillin and clindamycin resistance.

Main Results:

• Methicillin-resistant S. aureus (MRSA) accounted for 16.7% (n=11) of all S. aureus isolates.
• High rates of clindamycin resistance were observed: 60% in methicillin-sensitive S. aureus and 82% in MRSA.
• These findings highlight significant clindamycin resistance in pediatric S. aureus infections.

Conclusions:

• Pediatric S. aureus infections in Kolkata show concerning levels of antibiotic resistance.
• Methicillin-resistant S. aureus is prevalent, and clindamycin resistance is particularly high in both sensitive and resistant strains.
• Local antibiotic resistance data is essential for guiding empirical therapy in pediatric infectious diseases.
