Increased incidence of drug resistant uropathogens is attributed majorly to asymptomatic bacteriuria infections. This study was designed to determine the prevalence and antibiogram of bacteriological agents on asympotmatic bacteriuria among University students. Early morning midstream urine samples were collected from 218 student participants comprising of 110 (51%) and 108 (49%) females and males respectively. Isolates were cultured on MacConkey and Mannitol salt agar, characterized and identified using Gram stain, morphological and biochemical tests. Organisms isolated were Staphylococcus aureus, Escherichia coli and Staphylococcus saprophytic. Significant bacteriuria was observed in 8 out of the 48 (22%) bacteriuria positive, while 170 (72%) showed no growth of the test organisms. Staphylococcus aureus had the highest prevalence of 48% followed by Escherichia coli (26%) and Staphylococcus saprophytic (26%). All the bacterial isolates showed high susceptibility to Gentamicin. Staphylococcus isolates (Staph. aureus and Staph. saprophytic), showed very high resistance to the Beta lactam antibiotics used in the study, Escherichia coli was moderately resistant to the Beta lactams. The prevalence of asymptomatic bacteriuria among the University students is 4%. Staphylococcus aureus was the most frequently occurring organisms amongst those with significant bacteriuria. This study showed high rate of antibiotic resistant uropathogenic bacteria associated to asymptomatic bacteriuria treatment.
