Antibiotic resistant bacteria isolated from Agulu lake in Anambra State of Nigeria West Africa

This research investigated the antibiotic resistant bacteria isolated from Agulu Lake in Anambra state of Nigeria. Water experiment was carried out on four (4) water samples aseptically collected from different points in the Agulu Lake. The samples were analyzed for physicochemical features, Most Probable Number (MPN), Gram stain, microscopy, motility, biochemical traits and antibiotic susceptibility tests using standard microbiological instrumentation. The results were analyzed through inferential statistics. The bacterial isolates were characterized based on their Gram stain, microscopy, motility and biochemical properties. The degree of susceptibility of the isolates against conventional antibiotics was determined using antibiotics’ impregnated discs assay. The physicochemical characteristics revealed the following average results: acidic pH of 6.0, temperature of 34 0C and turbid. The highest MPN value was recorded by water sample collected from site D while the lowest MPN value was found at site B of the stream. The results of Gram stain, microscopy, motility and biochemical characterization inferred the presence of Pseudomonas species and Escherichia coli in the water samples. The study confirmed that Agulu Lake in Anambra state of Nigeria contains bacteria that are resistant to most conventional antibiotics. So, there is a call for massive information dissemination to all for caution towards health promotion.
