Individual scientists and groups of researchers perform experiments to test hypotheses about biological phenomena. After experiments are completed and duplicated, researchers attempt to persuade others to accept or reject their hypotheses by presenting the data and their interpretations. The report or the scientific paper is the vehicle of persuasion; when it is published, it is available to other scientists for review. This model of technical report in biology therefore looks into the right way in putting the reports together in a way that is acceptable to other researchers and readers. Description: Technical report writing in biology discusses biological research involving laboratory work and biological terms. 2016-06-15T00:00:00Z ir.bowen.edu.ng:8181/jspui/handle/123456789/2036 Title: Multidrug resistance profile and extended-spectrum beta-lactamase production in faecal escherichia coli isolated from hiv and tb patients in Ekiti-State, Nigeria Authors: Aina, O. O.; Ajayi-Odoko, O. A. Abstract: With the increasing use of antibiotics and widespread of antibiotics resistance which has been amplified by the production of ESBLs in clinical isolates; the study was to determine the multidrug resistance Profile and Extended-spectrum Beta-lactamase production in faecal Escherichia coli isolated from HIV and TB Patients in Ekiti-State, Nigeria. Three hundred isolates of E. coli were obtained from the stool samples of HIV/AIDS patients, TB patients and apparently healthy individuals. The sample was cultured on Eosin-Methylene Blue (EMB) agar plate and incubated at 37ºC for 24 hours. The colony showing greenish metallic sheen was identified using the conventional biochemical. Antimicrobial susceptibility testing was performed by Kirby-Bauer disc diffusion technique. Bacteria showing resistance to at least three different classes of antibiotics were considered multidrug resistant (MDR). Extended spectrum beta-lactamase production was detected by combined disc method using ceftriaxone/cefotaxime and Amoxicillin/clavulanic acid discs.A total of 141(47%) males and 159(53%) female patients were involved in the study. Based on the age distribution, age group 30-39(n=80) has the highest percentage while age group 60 and above (29) has the lowest participation among the age groups. E. coli isolated from HIV/TB co-infected reveals 40(80%), 26(52%), 21(42%) and 37(82%) resistant to SXT, AMC, SAM and AZM respectively while 24(48%), 36(72%), 23(46%) and 26(52%) of E. coli isolated from HIV patients on treatment were resistant to SXT, AMC, SAM and AZM. Tuberculosis patients on anti- TB treatment had 45(90%), 34(68%), 36(72%) and 44(88%) of the isolates resistant to SXT, AMC, SAM and AZM respectively while E. coli isolated from newly diagnosed HIV patients were 31(62%), 29(58%), 15(30%) and 27(54%) of the E. coli were resistant to SXT, AMC, SAM and AZM. Similarly, 33(66%), 36(72%), 15(30%) and 39(78%) of the isolated E. coli from newly diagnosed TB patients showed resistance to SXT, AMC, SAM and AZM respectively. Among the 148 multiple antibiotic resistant E. coli isolates 38 (23.75%) were found to be Extended β-lactamase (EBLS) positive with majority of the positive EBSL E. coli isolate from TB and TB associated patients. The increase in the prevalence of ESBL among faecal E. coli, an indicator organism for enteric pathogens, however, express the urgent need for serious antibiotics stewardship and control among clinicians and other health personnel especially in developing and under developed countries for proper management of the immune impaired individuals. 2019-01-01T00:00:00Z ir.bowen.edu.ng:8181/jspui/handle/123456789/1443 Title: Effect of garlic (Allium sativum) extract on fungal spoilage and preservation of onion (Allium cepa) bulbs Authors: Oluranti, O. O.; Sangoyomi, T. E. Abstract: The study investigated the occurrence and virulence of some fungal pathogens causing rot of onions. Antifungal potentials of garlic extract against these fungi and its effects on shelf life were also studied. Ten percent aqueous garlic extract was used in fungal growth inhibition of artificially inoculated onion bulbs as well as used in fungal growth inhibition of artificially inoculated onion bulbs as well as whole bulb preservation experiments and sterile distilled water served as control in both experiments. Results showed that Aspergillus niger, A. niger, Penicillium and Rhizopus sp occurred in rotting onion bulbs and Aspergillus niger was found to be the most virulent, having a mean rot diameter of 1.94mm, followed by A. flavus (0.42mm), Rhizopus sp (0.15 mm), while Penicillium sp was the least virulent in causing rot in the bulbs, with 0.12 mm. Onion bulbs inoculated with blank agar disc showed no rot symptoms. There were significant differences between the control and treated samples at p<0.05.Garlic extract was effective in inhibiting mycelial growth of all fungal pathogens in the pretreated onion bulbs (Aspergillus niger (2.84 mm),Aspergillus flavus (1.61 mm), Penicillium (0.48 mm) and Rhizopus spp ( 0.54 mm)and were significantly lower than control at p<0.05. Whole onion bulbs (treated and control) remained healthy without any sign of rot until 4 weeks after storage however,mean rot reduction of 58% was observed in onion bulbs treated with 10% garlic extract at 9 weeks after storage. The untreated (control) samples developed rot symptoms after four weeks of storage. Garlic extract could be used to elongate shelf life of onions due to its antifungal and preservative potentials. 2022-01-01T00:00:00Z ir.bowen.edu.ng:8181/jspui/handle/123456789/1442 Title: Studies on immunomodulatory and prophylactic properties of some wild Nigerian mushrooms Authors: Jonathan, S. G.; Olawuyi, O. J.; Oluranti, O. O. Abstract: The prophylactic potentials of five Nigerian higher fungi – Pleurotus tuber-regium, Pleurotus pulmonarius, Termitomyces robustus, Fomes lignosus, Lentinus subnudus and their combination in equal proportion (mixture extract) were investigated. The ethanolic fungi extracts were tested on sets of albino rats (Rattus norvegicus) infected with selected bacteria (Escherichia coli, Staphylococcus aureus, Salmonela typhi, Pseudomonas aeruginosa, Streptococcus feacalis and Bacillus subtilis. Extracts were orally administered at 1.0ml concentration against 0.1ml/cfu microbial suspension intraperitoneally . Survival rates of the experimental rats were monitored. Mixture of these extracts exhibited significant level of prophylactic effect against all the bacteria in the host organisms. 2012-01-01T00:00:00Z
