Item Antibiotic Susceptibility Profile of Uropathogens Isolated from Pregnant Women in Selected Hospitals in Ilorin(Nigerian Journal of Pharmaceutical Research., 2019-06) Olufadi- Ahmed, Haishat; Aliyu, Abdulmalik; David, Susan; Kola- Mustapha, Adeola; Diyaolu, AyobamiBackground: Urinary tract infection (UTI) is one of the most common infections among pregnant women and if untreated could lead to serious complications. Objective: This work was carried out to determine the prevalence rate of Enterobacteriaceae uropathogens and their antibiotics susceptibility profile among pregnant women attending two ante-natal clinics in Ilorin, Nigeria. Materials and Methods: A total of 111 pregnant women between the ages of 18-50 attending ante-natal clinic at University of Ilorin Teaching Hospital and Civil Service Hospital, Ilorin participated in the study. Mid-stream urine samples were collected and cultured on Cysteine-Lactose-Electrolyte Deficient agar. Presence of significant bacteriuria (> 105 cfu/mL) was determined using the plate count method. Antibiotic susceptibility testing was done using Kirby-Bauer disk diffusion technique. Results: Of the 111 urine samples collected, 27.9% of them were found positive on culture. Among the isolated organisms, Klebsiella oxytoca (25.7%) followed by Klebsiella pneumonia (22.9%), were the most prevalent. Isolated bacteria were resistant to at least one antibiotic with the highest resistance seen with amoxicillin (94.3%), streptomycin (77.1%) and nitrofurantoin (54. 3%). Amoxicillin-clavulanic acid (51.4%), ceftriaxone (51.4%), ceftazidime (34.3%), cotrimoxazole (51.4%), imipenem (2.9%), ciprofloxacin (14.3%) and gentamicin (25.7%) have the lowest rate of bacteria resistance. Of the isolates, 82.9% showed Multi-Antibiotic Resistance Index (MARI) ≥ 0.3. Conclusion: High prevalence of bacteriuria in both symptomatic and asymptomatic pregnant women was observed in the study areas. The alarming rate of multi-antibiotic resistance strain is therefore an indicator of a serious clinical problem in the community.Item Biofilm Detection and Antibacterial Susceptibility Pattern of Isolates from In-patients with Urinary Tract Infection in a Tertiary Hospital(Journal of Pharmaceutical Research, Development and Practice., 2018-12) Aliyu, Abdulmalik; Bello, Ronke; David, Susan; Olufadi-Ahmed, Haishat; Salami, Omatseye; Itodo, Ene; Kola- Mustapha, AdeolaA survey for the detection of biofilms amongst uropathogens was conducted in a Medical ward of a Tertiary hospital in Ilorin, Kwara State. This was done to determine the prevalence of biofilm producing uropathogens among patients with CA-UTI (Catheter-Associated Urinary Tract Infection) using MTP (microtitre plate) method. Effect of media variations in the production of biofilms and the antibiogram pattern of the isolates were also determined. Out of the 50 urine samples collected and analyzed, 27 (54.0 %) yielded growth and 28 isolates were identified. Klebsiella pneumoniae was the most prevalent (42.9 %), followed by Staphylococcus aureus (35.7 %) and Pseudomonas aeruginosa was the least (21.4 %). A total of 59. 3 % of the isolates were resistant to various antibiotics used and 39.3 % of the isolates were found to be multiple antibiotic resistant. Of the 28 uropathogens isolated, 21 (75.0 %) were biofilm formers comprising of 17.9 % high biofilm formers and 57.1 % of moderate biofilm formers while 25.0 % did not form biofilm in BHIsuc. High biofilm formation was observed in Staphylococcus aureus. There was variation in biofilm formation with different media as more isolates (75. 0 %) produced biofilm in BHIsuc than in TSBglu (67.9 %). Clinical isolates of Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas aeruginosa have potential of biofilm production which could lead to relapse of disease condition and eventually treatment failure in CA-UTI.
