Incidence of septicemia. Etiology and antimicrobial susceptibility testing among patients admitted to tertiary care hospital
Introduction: Septicemia is considered as an important cause of life-threating infections. The study was aimed at determining the incidence of septicemia considering different age groups and gender among suspected patients admitted to a tertiary care hospital in Iraq.
Methodology: A total of 168 blood samples were collected and cultured using BacT/Alert 3D automated system. The isolated pathogens were identified and subjected to antimicrobial susceptibility testing using automated Vitek 2 Compact system.
Results: Out of 168 blood samples, 53 (31.5%) gave positive microbial growth. Thirty-three samples (62.3%) came from male patients and 20 (37.7%) from female ones, both gender and microbial growth were significantly related (P < 0.05). Age group (21 year - 30 year) was found to have the highest percentage of positive growth (26.4%) while age group (51 year - 60 year) the lowest percentage (5.7%) of positive growth. Both microbial growth and age group were found to be associated to a significant level (P < 0.05). 36 isolates (67.9%) were Gram negative, 15 isolates (28.3%) were Gram-positive and 2 isolates (3.8%) were fungi. Salmonella typhi (41.7%) represented the most common pathogen isolated followed by Acinetobacter baumannii (22.2%). An isolate of Pseudomonas aeruginosa showed resistance to all antibiotics used.
Conclusion: Community-acquired septicemia occurred mainly in male than female. Salmonella typhi and Acinetobacter baumannii represented the most frequent causative agents of community-acquired septicemia. Antimicrobial susceptibility testing should be performed to detect the antibiotic of choice for each pathogen causing community-acquired septicemia.
