Bacteriological Analysis of Water Samples from Ebonyi State University, Abakaliki, Nigeria
The bacteriological examination of water samples from Ebonyi State University Abakaliki was investigated using standard microbiology procedures. Water samples were collected from the hostels, laboratories, the office complex, and lecture rooms. The samples were analysed using the multiple tube fermentation method also called the most probable number method. The isolated microorganism was characterized and identified based on morphological, biochemical, and sugar fermentation tests and the result of isolation revealed that Pseudomonas aeruginosa is the contaminating microorganism. The identified bacteria isolate was tested against some commercially available antibiotics using disc diffusion techniques. The result of the Antimicrobial sensitivity study showed that Pseudomonas aeruginosa was resistant to most of the antibiotics (amikacin, sulphamethoxazole, chloramphenicol, ceftriaxone, clindamycin, amoxicillin, cefoxitin, and ceftazidime) except (gentamicin, and ciprofloxacin). The reason for the high resistance of Pseudomonas aeruginosa to antibiotics was not identified by this study, but it is rather an area the researcher will hope to explore in further research to support the discovery of more effective and efficient antibiotics. The result of this study further highlights the significant challenges facing Nigeria in its bid to meet the UN Sustainable Development Goal target 6.1 which calls for universal and equitable access to safe and affordable drinking water. Therefore, quality control treatment is recommended for all sources of water to ensure it meets the UN, WHO, and NAFDAC’s approved standards before its consumption and usage to avoid an outbreak of water-borne diseases among the staff, and students.
