Background: Multi-drug resistant Escherichia coli has become a major threat and cause of many urinary tract infections (UTIs) in Abeokuta, Nigeria. Objectives: This study was carried out to determine the resistant plasmids of multidrug resistant Escherichia coli isolated from (Urinary tract infections)UTIs in Abeokuta. Methods: A total of 120 Escherichia coli isolates were obtained from urine samples collected from patients attending inpatient and outpatient clinics presenting UTI; with their biodata. Antibiotics susceptibility was performed and multi-drug resistant isolates were selected for plasmid profiling. Plasmids were extracted by the alkaline lysis method, electrophoresed on 0.8% agarose gel and profiled using a gel-photo documentation system gel. Results: Escherichia coli isolates obtained shows high resistance to cloxacillin (92.5%), amoxicillin (90.8%), ampicillin (90.8%), erythromycin (75.8%), cotrimoxazole (70.0%), streptomycin (70.0%) and tetracycline (68.3%) while 85.8% and 84.2% were susceptible to gentamycin and ceftazidime respectively. Sixteen Escherichia coli strains were observed to be resistant to more than two classes of antibiotics. The resistant plasmid DNA was detectable in 6(37.5%) of the 16 multidrug resistant Escherichia coli having single sized plasmids of the same weight 854bp and were all resistant to erythromycin, cefuroxime, cloxacillin, amoxicillin, ampicillin and cotrimoxazole. Conclusion: This study has highlighted the emergence of multidrug resistant R-plasmids among Escherichia coli causing urinary tract infections in Abeokuta, Nigeria. There is a high level of resistance to many antimicrobials that are frequently used in Abeokuta, Nigeria.

Background:Neonatal sepsis is a significant cause of neonatal mortality in developing countries. The aetiological agents and their antimicrobial susceptibility patterns are dynamic.Objectives: This study determined clinical features, aetiology, antimicrobial susceptibility and clinical outcome of neonatal sepsis in a Nigerian Tertiary Hospital.Methods: Neonates undergoing sepsis evaluation at a Nigerian Tertiary Hospital were included in the study. Demographic and clinical information were obtained using standard questionnaires. Blood samples were cultured on MacConkey, Blood and Chocolate agar. Isolated bacteria were identified based on morphology, Gram stain appearance and standard commercially prepared biochemical tests. Antimicrobial susceptibility testing was performed on Mueller-Hinton agar using the Kirby-Bauer method.Results: Eighty-five of the 180 neonates admitted during the study period were recruited. Fifty-five neonates presented with early-onset sepsis and 30 with late-onset sepsis. Culture-proven sepsis was detected in 19 (22.4%) neonates. The incidence of culture-proven sepsis in the hospital was 2.8/100 live-births. The most common clinical feature at presentation was respiratory distress. Gram-negative bacteria accounted for 78.9 percent of all isolates and were the only organisms encountered in earlyonset sepsis. Isolated pathogens were predominantly Klebsiella spp (31.6%), Enterobacter spp (21.1%) and coagulase-negative Staphylococci (15.8%). The isolates were most sensitive to ofloxacin. Gram-negative bacteria showed high resistance to cefuroxime and ampicillin. The case-fatality rate was 26%.Conclusion: Gram-negative bacilli, especially Klebsiella spp, was predominant. Neonatal sepsis persists as a cause of mortality in this region. Regular antimicrobial surveillance for empirical treatment remains an important component of neonatal care.

Background: Few studies exist on hospital-based seroprevalence of triple positivity of HIV/HBV/HCV in Nigeria. Objectives: The study aimed at determining the triple positivity of HIV, HBsAg and HCV among HIV-infected individuals in Abeokuta, Nigeria and defining the influence of these triple infections on CD4+ counts of HIV-infected individuals as antiretroviral therapy improves in Nigeria. Conclusion:The study further confirms that triple positivity of HIV/HBV/HCV infection is common in Abeokuta, Nigeria. Testing of these triple infections should be a big concern in the best choice and commencement of ART. Also, the study showed that consistent and prolonged use of HAART had a positive impact on the CD4 count of HIV-infected individuals.

Objective: The aim of this study was to determine the time interval between human immunodeficiency virus (HIV) infection and the first diagnosis among drug-naïve individuals in Badagry, Nigeria. Subjects and Methods: A sample of 213 subjects who tested HIV positive for the first time were enrolled in this study. The HIV diagnosis was performed using Startpak® and Determine® kits, and a CD4 count was carried out using a FACS Count® flow cytometer. The mean CD4 values were determined by gender and age groups. The time interval between initial HIV infection and first testing was calculated based on the average CD4 decay rate per calendar year, and data analysis was performed using SPSS software. Results: At diagnosis, the mean CD4 values showed that females recorded 270 cells/µl and males 244 cells/µl. By age range, individuals <25 years recorded 437 cells/µl, those between 25 and 40 years of age had 237 cells/µl, and those aged ≥41 years had 192 cells/µl. There was a significant difference between CD4 cell categorization and age range (p < 0.001). Subjects aged between 25 and 40 years recorded the highest distribution of all CD4 cell counts. The time interval between infection and testing for females was 8.1 years and for males 6.7 years. Within the age group <25 years the interval was 5.1 years, whilst it was 8.1 years for those aged ≥41 years. Conclusion: Most of the population presented for testing during the advanced stages of infection. We suggest an upscaling of HIV voluntary counseling and testing to encourage early detection and better treatment outcomes.
