Microbiological profile of abscesses of different body sites in a tertiary care hospital – the silent killer

Background: Abscess, an infection with viable infecting organisms and polymorphonuclear cells, contained within a fibrous capsule, limiting the infection, preventing its further spread. It may be monomicrobial or polymicrobial. Aims Objectives: The aims of study were to determine microbiological profile abscesses different body sites associated complications. Materials Methods: An observational was conducted in our department 35 pus samples from between August 2022 December 2022. Gram stain, Z-N fungal aerobic, anaerobic, culture performed. Statistical analysis done by statistical tool R. Results: Out samples-limb, liver,paraspinal, psoas, appendicular, breast, perineal, ear, brain lung 11,4,2,3,1,7,2,2,2,1 respectively. Most common limb,ear,paraspinal breast MRSA (Methicillin resistant Staphylococcal aureus). Also most – Escherichia coli liver abscess, Enterobacteriaceae Pseudomonas aeruginosa psoas appendicular Enterobacter aerogenes Actinomyces species Candida auris abcesses. No growth also found few samples. Their susceptibility testing showed-MRSA strains susceptible both Vancomycin Linezolid, gram negative bacteria Cephalosporins, Piperacillin-tazobactam, Carbapenems, polymixins, etc. C.auris all antifungals. blood collected - ten patients showed fever bacteremia one candidemia . They treated systemic antimicrobials along drainage and/or surgical resection. Conclusion: Abscesses must suspected cases non-resolving with/without septicemia promptly appropriate based on report
