Analytical Study of Bacterial Flora Isolated from Data on Mid Stream Urine [MSU] Samples were Sent for Examination & there Antibiotic Sensitivities & Resistance front August - October 2008 At Labasa Hospital

The thorough 3 month Retrospective analytical Study (August - October 2008) on MSU samples sent to the Microbiology Laboratory depicted an average of 257 MSU samples processed for each month with a cumulative total of 772. The rate of positive identification of bacteria in the MSU samples sent was 41/month which computed to be approximately 16% successful
identification rate. For the 1 year Retrospective analysis (August 2008 - August 2009) a total number of 4347 MSU samples were sent for analysis which computed to an average of334 MSU
samples for every month. Out of 4347 MSU samples sent, 832 (approximately 19%) tested positive for pathogens including bacteria and fimgi. An average of 64 samples (approximately 19%) tested positive for bacteria/fimgi each month. According to the analysis more females had MSU Positive samples growmg bacteria as compared to males and the most number of positive samples were collected for the 14-30 year
age group and the second largest cohort was for the 45-60 year group. Most samples tested positive for Gram Negative Bacilli (GNB) bacteria namely Escherichia coli and Klebsiella pneumoniae and rarely for Trichomonas vagina/is. Gram Positive Cocci (GPC -Clusters) were the second most common bacteria isolated from the positively identified samples mainly of the Staphylococcus species. Candida fungi was the third and Pseudomonas species was the fourth most common organism isolated. The antibiotic most effective against the organisms isolated was Nitrofurantoin with Nalidixic Acid, Cefaclor and Gentamicin included in the top 4 most effective antibiotics. The most resistance was documented to the antibiotic Ampicillin with Trimethoprim, Cefaclor and Gentamicin being the 2nd, 3rd and 4th most resistant response respectively. The outcome of Urine Pregnancy tests sent to the Microbiology lab for verification showed out of the total number of tests ordered which was 385 some 129 tested positive (33.5%).
