Opis:
Background: 3T3-L1 preadipocyte is the most commonly used cell line in in vivo studies of obesity. One of the main concerns in 3T3-L1 preadipocyte culture is microorganism contaminations. The objective of this study was to determine the appropriate antibiotics to prevent contaminations in 3T3-L1 cultures. Method: This study used descriptive analysis. Frozen 3T3-L1 preadipocytes were thawed and cultured in DMEM-10% FBS-1% penicillin-streptomycin, DMEM-10% FBS-1% penicillin-streptomycin-fungiezone, or DMEM-10% FBS-0.2% ciprofloxacin 200 mg/100 ml. After 24-hour incubation, the cells were observed under the microscope for any change in the medium colour, presence of abnormal structures, and abnormality in cell morphology. Results: The usage of 1% penicillin-streptomycin, 1% penicillin-streptomycin-fungiezone, or 0.2% ciprofloxacin 200 mg/100 ml maintained the clean medium and conserved normal fibroblast-like morphology of the cells. Conclusion: This study suggested that 1% penicillin-streptomycin, 1% penicillin-streptomycin-fungiezone, or 0.2% ciprofloxacin 200 mg/100 ml can be utilized in 3T3-L1 preadipocyte cultures to prevent contaminations.

Opis:
Urinary tract infection (UTI) is one of the most common diseases encountered worldwide. In this study, urine samples were collected from thirty women of child bearing age (18-25 years) to determine the prevalence of bacteriuria, as well as the presence of pus cells and white blood cells which are signs of infection. The urine microscopy result revealed that 7 (23.3%) of the sample had greater than 10 leucocytes per high power field. Only four of the samples had a significant number of pus cells. The bacteria count recorded ranged from 25 cfu/0.001 ml to 276 cfu/0.001 ml. Of the samples, 13 were positive for bacteriuria having bacterial count greater than 100 cfu/0.001 ml. The bacteria isolates include Klebsiella spp. (3.8%), Streptococcus spp. (2.5%). Escherichia coli (62.5%) and Staphylococcus spp. (21.2%). Of these, Klebsiella spp. was the least prevalent and Escherichia coli had the highest number of occurrence. These organisms were very sensitive to Ciprofloxacin, Pefloxacin, Zinnacef and Gentamycin according to the antimicrobial susceptibility test carried out. Ciprofloxacin was found to be the most effective antibiotics against all the bacterial isolates. Here, zones of inhibition ranged from 15 mm (Streptococcus spp.) to 20 mm (Escherichia coli). All the bacterial isolates were resistant to Amoxicillin, with zones of inhibition between 11 (Klebsiella spp., Escherichia coli, Staphylococcus spp.) and 13 mm (Streptococcus spp.). Since the prevalence of asymptomatic bacteriuria is high, early diagnosis and proper treatment is necessary in order to prevent it from becoming symptomatic.

Opis:
The antibacterial activity of a PVP-ZrO2 nanocomposite was investigated against pathogenic bacteria S. aureus and K. pneumoniae after antibacterial sensitivity was determined and one isolate was chosen that showed more antibiotic resistance. Herein, the Co-culture technique was used to calculate percent reduction of bacteria. The results that were obtained in this method show that ZrO2 nanoparticles have inhibitory effect against pathogenic bacteria gram negative bacteria and gram positive bacteria - with reduction of growth reaching 100% to both S. aureus and K. pnumoniae at 5, 10, 15, 20 and 25% ZrO2, compared with control. The resistance patterns of S. aureus and K.pnuemonia isolates show the Moxifloxacin (MXF) is the best antibiotic for both bacteria - with sensitivity at 100%, while resistance to Ceftriaxone (CRO) is at 90% S. aureus, and at 80% K. pnumoniae. The polymer-nanocomposite was prepared by weight percentage wt. % of (PVP) being dissolved in (10) ml of distilled water, with weight percentages 5%, 10%, 15%, 20% and 25% of ZrO2 nanoparticles added.

Opis:
This study was conducted to investigate the occurrence of antibiotic resistance, including β-lactamase and extended spectrum β-lactamase production among enteric bacteria isolated from hospital wastewater from selected hospital within Ibadan. Physico-chemical analysis of hospital wastewater samples was done, enteric bacteria were isolated and identified using convectional biochemical tests while the selection of potential ESBL-producing bacteria was carried out using disc diffusion method and ESBL detection using double synergy test. The turbidity of the wastewater samples ranged between 4.45-6.5 NTU and total suspended solids ranged between 3.4- 45.5 mg/L. While electrical conductivity was between114.25-214 µs/m, the biological oxygen demand was between 25.8-31.25 mg/L and chemical oxygen demand ranged between 41.25-45.38 mg/L. Of the 200 bacteria isolated 35(17.5%) produced ESBL; 14(40%) from the tertiary hospital and 21(60%) from private hospital out of which 85.7%, 80% and 65.7% showed resistance to sulphamethxazole/Trimetoprim, streptomycin and tetracycline respectively, while resistance to meropenem (8.6%) was low. Among the ESBL-producing isolates, K. pneumonia had the highest (15(42.8%) rate of occurrence. This study revealed a need for hospital wastewater to be properly treated before discharged into water bodies and the environment to forestall the indiscriminate discharge of wastewater harbouring ESBL-producing bacteria.

Opis:
The prevalence of antimicrobial resistance among food pathogens has increased during recent decades. In this work, pathogenic bacteria such as Staphylococcus aureus, Salmonella spp., Shigella spp., and E. coli were isolated following standard methods. The bacterial isolates were then tested for their sensitivity to common antibiotics using the disc diffusion method on Mueller-Hinton Agar. All of the pathogenic bacteria were found to be resistant to erythromycin and almost all were sensitive to penicillin.
