ABSTRACT
In this retrospective study, we determined the incidence, serovars, and antibiogram of Vibrio cholerae isolated from 102 clinical stool samples collected from rice water diarrheic patients during an outbreak (May - July 2017) in Ilorin metropolis, Nigeria. The culture positive rate of the V. cholerae isolates was 41.2%, with 41 and 1 isolates from O1 (Inaba) and non-O1/O139 serogroups, respectively. The isolates were the most susceptible to ciprofloxacin (76.2%) followed by amoxicillin-clavulanate (71.4%). However, all isolates were resistant to ampicillin and tetracycline. In conclusion, V. cholerae O1 was the predominant circulating serogroup exhibiting multi-drug resistance during the outbreak.

ABSTRACT
Purpose: To determine the association between isolates in the middle ear (ME) and nasopharynx of patients with chronic otitis media in Ilorin, north-central Nigeria. Methods: An ethically approved case control study was carried out in the Ear, Nose, and Throat clinic amongst consenting cases using normal subjects as controls. A microbiology investigation form giving the results for otoscopy, aspirate and swabs was filled out for both the ME and nasopharynx. The experimental procedure was carried out and bacteria were identified according to colony characteristics, morphological appearance, Gram-staining, and standard biochemical testing. Data obtained were analysed with SPSS version 16.0 and Epi Info 3.5.1 using the mean, standard deviation and chi-square results. Results: A total of 140 cases and 70 controls, were recruited. The Gram stain reaction of the ME aspirates were positive in 28.6% and negative in 71.4% of cases. Nasopharyngeal swabs revealed 64.3% Gram positive and 35.7% negative organisms. Overall, there was no relationship between the ME and nasopharyngeal isolates amongst cases, with a P value of 0.000. However, there was a relationship amongst the isolate from the nasopharynx of cases and controls, with the exception of Klebsiella pneumoniae, at P < 0.009. Conclusion: There was no relationship amongst the bacterial isolate from the ME and nasopharyngeal specimen of patients with otitis media.
ABSTRACT
To determine the prevalence of asymptomatic bacteriuria, bacteriology and sensitivity pattern in Ilorin using the gold standard of urine culture. A prospective study was carried out from 1st July to 31st October 2007, at the University of Ilorin Teaching Hospital [UITH] on 125 consenting asymptomatic pregnant women, A structured proforma was used to collect information from the women and a midstream urine specimen collected for bacteriological culture, Of the 125 pregnant women, 50 had bacteriuria on urine culture giving a prevalence of 40%. The mean age of the women was 28.5 years with a standard deviation of 4.95. The age ranged between 14 and 40 years. Staphylococcus aureus was the commonest pathogen isolated [72%], followed by Proteus spp [14%]. Most of the organisms showed good sensitivity to Nitrofurantoin and gentamicin. The prevalence of asymptomatic bacteriuria in Ilorin is high and routine urine culture is advocated for all pregnant women at booking
