Implication

Microbiological analysis reveals predominant Gram-negative bacilli and high methicillin resistance in pyogenic wound infections, highlighting the need for targeted antibiotic therapy.

Key Points

To isolate aerobic bacterial pathogens from clinical pus samples and determine their antibiotic susceptibility patterns to guide empirical treatment.
Analyzed N=370 pus samples obtained via sterile aspiration or swabs using standard microbiological microscopy and aerobic culture for 48 hours at 37°C.
Identified isolates and evaluated antibiotic susceptibility using Kirby-Bauer disc diffusion on Mueller-Hinton agar interpreted by 2021 CLSI guidelines.
Of 370 pus specimens, 71.35% (n=264) were culture positive, whereas 28.65% (n=106) yielded no aerobic bacterial growth.
Gram-negative bacilli represented 60.98% (161/264) of isolates, predominantly Escherichia coli (38.5%) and Pseudomonas aeruginosa (28.84%).
Gram-positive cocci constituted 39.02% (103/264) of isolates, led by methicillin-sensitive Staphylococcus aureus (33.98%) and methicillin-resistant Staphylococcus aureus (31%).
