The presence of tetracycline resistance genes in Acinetobacter species justifies the observed phenotypic resistance to oxytetracycline and intermediate resistance to minocycline. High phenotypic resistance and the presence of some resistance genes in Staphylococcus species is a possible threat to public health and suggests animals to be important reservoirs of antibiotic resistance determinants in the environment. Indiscriminate use of antibiotics induces this kind of antibiotic resistance and should be discouraged. Personal hygiene is encouraged as it reduces the load of Acinetobacter species contacted from the environment that may be difficult to control. Commensal Stenotrophomonas maltophilia are as important as their clinical counterparts due to their roles in opportunistic infection, antibiotic resistance and their associated genes, especially sul gene.

Average log reductions in viable cell counts for all the extracts ranged between 0.1 Log10 and 7.5 Log10 cfu/ml after 12 h interaction at 1 × MIC and 2 × MIC. Most of the extracts were rapidly bactericidal at 2 × MIC achieving a complete elimination of most of the test organisms within 12 h exposure time. The effect of combinations of the crude extracts of H. pedunculatum leaves and eight antibiotics was investigated by means of checkerboard and time-kill methods. In the checkerboard method, synergies of between 45.83-56.81 percent were observed and this is independent of Gram reaction, with combinations in the aqueous extract yielding largely antagonistic interactions (18.75 percent). The time kill assay also detected synergy that is independent of Gram reaction with a ≥ 3Log10 potentiation of the bactericidal activity of the test antibiotics. We conclude that the crude leaf extracts of H. pedunculatum could be potential source of broad spectrum antibiotics resistance modulating compounds. The interactions between crude extracts of H. longifolium in combination with six first-line antibiotics using both the time-kill and the checkerboard methods were carried out. The time-kill method revealed the highest bactericidal activity exemplified by a 6.7 Log10 reduction in cell density against Salmonella sp. when the extract and Penicillin G are combined at ½ × MIC. Synergistic response constituted about 65 percent, while indifference and antagonism constituted about 28.33 percent and 6.67 percent in the time kill assay, respectively. The checkerboard method also revealed that the extracts improved bactericidal effects of the antibiotics. About 61.67 percent of all the interactions were synergistic, while indifference interactions constituted about 26.67 percent and antagonistic interactions was observed in approximately 11.66 percent. The in vitro antioxidant property and phytochemical constituents of the aqueous crude leaf extracts of H. longifolium and H. pedunculatum was investigated. The scavenging activity on superoxide anions, DPPH, H2O2, NO and ABTS; and the reducing power were determined, as well as the flavonoid, proanthocyanidin and phenolic contents of the extracts. The extracts exhibited scavenging activity in all radicals tested due to the presence of relatively high total phenol and flavonoids contents in the extracts. Our findings suggest that H. longifolium and H. pedunculatum are endowed with antioxidant phytochemicals and could serve as a base for future drugs. Bioactivity-guided fractionation of the leaves of H. longifolium and H. pedunculatum yielded two known compounds. From the n-hexane fraction of H. longifolium a compound was isolated (Stigmasterol) and from the ethyl acetate fraction of H. pedunculatum another compound (β-sitosterol) was isolated. The compounds were isolated and identified using various techniques. The antimicrobial, anti-inflammatory, antioxidant, analgesic and anti-pyretic activities of these compounds have been reported in literatures. In general, the experiments and tests conducted in this study appear to have justified the folkloric medicinal uses of H. longifolium and H. pedunculatum for the treatment of stress related ailments and wound infections and make a substantial contribution to the knowledge base of the use of herbal medicine for the treatment of the microbial infections.]]> Wed 12 May 2021 19:21:16 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:16168 Wed 12 May 2021 19:16:25 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:18138 Wed 12 May 2021 19:05:46 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29315 Wed 12 May 2021 19:05:10 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:18161 Wed 12 May 2021 19:02:18 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11721 Wed 12 May 2021 18:23:13 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:18137 Wed 12 May 2021 18:22:23 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11302 Wed 12 May 2021 18:20:05 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:34283 Wed 12 May 2021 17:58:29 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11644 Wed 12 May 2021 17:56:43 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:35651 Wed 12 May 2021 17:36:05 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:17324 Wed 12 May 2021 17:24:31 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:18180 Wed 12 May 2021 16:52:37 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29413 Wed 12 May 2021 16:52:31 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11263 Wed 12 May 2021 16:31:22 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:17342 Wed 12 May 2021 16:19:31 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:34180 Wed 12 May 2021 15:50:59 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40090 .05). The model chi-square value of 43.47 (approximately 44% ) was significant. Thus, the indication is that the model has a good fit in predicting the possibility of a fuel retail outlet being located in the core or peripheral zone of the metropolis as determined by the explanatory variables (the independent variables accounted for about 44% of possible factors which determined whether a fuel retail outlets is located either within the core or peripheral zones of the metropolis. The remaining 56% are factors not considered in the study). The result gotten from the in depth interview sessions corroborated the findings from the tested hypothesis. The third objective was to examine the effects which the supply chain technique employed (either vertically integrated model or third-party arrangement) has on the achievement of efficient and effective distribution of the products. In order to achieve this objective, all the 389 registered members of Petroleum Tanker Drivers (PTD) association who are members of the PTD in the metropolis were sampled, 265 (around 70%) of the distributed questionnaires were retrieved and used for the analysis. In depth interview sessions were also conducted with three different managers of the three major conglomerates in the downstream sector of the Nigerian petroleum sector. The result of one-way between subjects (ANOVA) which was conducted to compare differences in the management and performances of haulage services outsourced to the 3PLS and those run under VIM showed that there was a significant effect of ownership type on management performance (F (2,262) = 60.26, p<.05). The null hypothesis was therefore rejected while the alternate hypothesis was accepted. The findings from the interview sessions posted similar results. The fourth and final objective was to analyze the effect that the socio-economic attributes of the participants (haulers and managers of retail outlets) involved in the distribution of xxvi petroleum products has on the safe, efficient and cost-effective distribution of product and this was done through the use of descriptive statistics, inferential statistics and incisive analysis of the interview sessions. A total number of 265 (70%) out of the 389 registered members of Petroleum Tanker Driver Association (PTDA) participated in the study. Multiple regression analysis (MRA) was used to test this hypothesis. The result from the statistical analysis show that the use of stimulant, work condition, marital status and educational attainment/literacy level have joint influence on compliance (R2 = 0.31, F (4,260) = 29.72, p<.05). On the basis of the foregoing, the hypothesis is thus accepted. The result from the interview sessions confirmed the existence of strong relationship between the explanatory variables and the hypothetical dependant variable. The study recommended a review of the planning processes guiding the establishment of fuel retail outlets. The study also advocated that retailers should endeavour to have stronger control over the supply chain of their products this could done by investing more in VIM rather than outsourcing such functions to 3PLs. This will help in better business performances. Government agencies in charge of monitoring drug abuse among haulers are advised to be more proactive by the duo of prevention and punishment strategies. This should include advocacy campaign against drug abuse. Different ranges of punishments should also be meted out for individual haulers found culpable.]]> Wed 12 May 2021 15:06:55 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:41994 Wed 12 May 2021 14:35:26 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40183 Wed 12 May 2021 14:32:23 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40704 Wed 12 May 2021 14:29:14 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:41363 Wed 12 May 2021 14:25:59 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40969 Wed 12 May 2021 14:23:05 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40411 Wed 12 May 2021 14:06:40 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:43250 Tue 28 Sep 2021 15:37:01 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:63573 Tue 18 Apr 2023 16:29:51 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:43197 10 mg mL-1.
