Item Bacteriology of Some Liquid Herbal Products Sold in Ilorin - Kwara State Nigeria(Journal of Science and Practice of Pharmacy., 2019-12) Bello, R H; David, M.S; Olutayo, A. O; Abdulrazaaq, K.O; Aliyu, A; Olufadi – Ahmed, H. Y; Salami, O.T; Lawal, B. A; Akerele, J. OPurpose: This study aims to establish the safety and/or potential public health dangers associated with the consumption of liquid herbal preparations (LHP) sold in Ilorin-Kwara State. Methods: Ten LHPs were randomly collected from three locations, kept under cold chain and transported to the Laboratory. All samples were evaluated for bacterial load using aerobic plate count method and bacterial isolates were presumptively identified using standard microbiological methods. Furthermore, Gram negative bacteria were identified using 12A Microbact ® Identification kits. Results: Sixty percent (60%) were fresh and faint, 4 (40%) were stale and putrid in smell as well as free of foreign matter. pH and bacterial load of samples ranged from 3.60 to 9.75 and 2.5 x 102 to 4.4 x 106 CFU/ mL respectively. Five (5) genera of bacteria, namely; Klebsiella species 10 (29.41%), Bacillus subtilis 8 (23.53%), Enterobcter spps. 7 (20.59%), Staphylococcus aureus 6 (17.65%) and Serretia marcescens 3(8.82%) were isolated from these LHPs. All isolates were resistant (100%) to Sulphamethoxazole trimethoprim combination. Amoxocillin clavulanate was active against 62.50% of K. pneumonia and S. marcescens isolates. Also 50% of K. oxytoca and E. gergoviae were susceptible to Amoxocillin clavulanate combination. Approximately, 8 (80%) of LHPs had bacterial load of 2.5 x 102 to 4.4 x 106 CFU/ mL and 2 (20%) yielded no growth. In addition, 40% of LHPs had bacterial load of 106 CFU/mL beyond the 104 CFU/mL permissible limit stated by European Pharmacopoeia. Conclusion: The observed high bacterial load and the presence of S. aureus as well as enteric bacteria of public health importance in these LHPs underscore the potential risk inherent in the consumption of these preparations. Therefore, public health awareness campaign on the dangers of unapproved LHPs consumption should be instituted.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 & Practice, 2018-12) Aliyu, A; Bello, R. H; David, M. S; Olufadi-Ahmed, H. Y; Salami, O. T; Itodo, P. E; Kola-Mustapha, A. TA 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.
