Abstract

Waterborne diseases remain a significant public health concern, particularly in communal living settings like hostels. This study aimed to isolate and identify microorganisms present in different water sources in Bouesti hostels water and determine their antibiotic sensitivity patterns.
Water samples were collected from Bouesti Hostel and processed using standard microbiological techniques. Microorganisms were isolated and identified using Gram staining, biochemical tests, and API kits. Antibiotic sensitivity testing was performed using the Kirby-Bauer disk diffusion method.
Water samples were analyzed, revealing the presence of various microorganisms, including: Escherichia coli (45%), Staphylococcus aureus (30%), Pseudomonas aeruginosa (20%), Klebsiella pneumoniae (5%).
Antibiotic sensitivity testing showed that; E.coli exhibited resistance to ampicillin (80%) and tetracycline (60%), S. aureus demonstrated resistance to methicillin (50%) and erythromycin (40%), P. aeruginosa was resistant to gentamicin (70%) and ciprofloxacin (50%). This study reveals a likely presence of pathogenic microorganisms in the water samples may pose health risks to users, and posits that regular water testing, proper disinfection and education on hygiene practices are essential to prevent waterborne diseases in communal living settings.
