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. Personal hygiene is hereby advocated especially when in contact with soil, plants and plants’ rhizospheric soil.]]> Tue 07 May 2024 08:48:34 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11395 Thu 13 May 2021 09:14:05 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11240 0.05); and efficient bactericidal activity (100% bacterial cells killed) at 1/2MIC and 4xMIC over different time intervals, 36-72hrs and 18-72hrs respectively. The appearance of bands on the thin layer chromatography (TLC) chromatogram spotted with the chloroform extracts of PH and CRT; and developed with hexane: ethyl acetate: acetic acid (HEA) and methanol: acetic acid: water (MAAW) solvent systems indicated the presence of compounds. Purification of the compounds contained in these extracts over silica gel column yielded numerous fractions which were evaluated for antibacterial activity and purity. PHF5 was the most active fraction with a mean MIC50 value of 1.25mg/mL. Volatile compounds belonging to different known chemical families in honey were identified in all the active fractions obtained from PH. Conversely, only four compounds were identified in the active fractions obtained from CRT hence the non volatile constituents could be of prime relevance with respect to antibacterial activity of this honey. Of novelty was the presence of thiophene and N-methyl-D3-azirdine compounds, essential precursors used for the synthesis of natural products and pharmaceuticals with vital biomedical properties. Linalool demonstrated potent inhibitory (MIC95, 0.002- 0.0313mg/mL) and bactericidal activity (0.0039-0.313mg/mL) against the test isolates. On the other hand, a significant difference was recorded (P < 0.05) in comparing the activity of linalool compound to the fractions. PH could serve as a good economic source of bioactive compounds which could be employed as template for the synthesis of novel anti-H. pylori drugs. However, further studies are needed to determine the non volatile active ingredients in PH and CRT as well as toxicological testing]]> Thu 13 May 2021 05:55:33 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11689 Thu 13 May 2021 05:21:37 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11149 Thu 13 May 2021 05:07:39 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11427 Thu 13 May 2021 03:41:16 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11536 Thu 13 May 2021 03:30:16 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:16186 Thu 13 May 2021 02:57:25 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11840 Thu 13 May 2021 02:26:31 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11306 Thu 13 May 2021 02:20:16 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11820 0.05) on the weights of the heart, liver, spleen, or the gizzard, although the bursa for T2 birds was the lightest (P < 0.05); while gizzard erosion score was highest in T2 birds. All of the nutrients measured, except for fat, had negative intercepts that were significantly different (P < 0.05) from zero, indicating the presence of endogenous fecal losses. Tibiae length (TL) was highest in T2. The dried defatted weight (DW) was heaviest (P < 0.05) for T3 (11.20 ± 0.347) and T5 (11.08 ± 0.328). A positive correlation (r = 0.667; P < 0.01) between TW and DW was observed. There were no dietary effects on bone breaking strength (BBS), but T1 tibiae had highest resistance to breaking force (T1 > T4 > T3 > T2 > T5). Calcium was highest (P < 0.05) in T1; and lowest inT2 and T5. Phosphorus levels were lowest (P < 0.05) in T1; and highest (P < 0.05) in T5 compared. The highest Ca: P ratio was obtained in T4 (P < 0.05); while the ash percent was highest (P < 0.05) in T1. Drip loss increased as L* values increased; and a negative correlation was observed between L* and pH. On D1, C18: 0 and C22 in T2, while C15:0 was highest in T4. On D1, C20:2, C20:3n6 and C22:6n3 were highest in T2 (P < 0.05); T4 had the highest C18:3n6 (P < 0.05), while C20:2 was highest in T5 (P < 0.05). The P/S ratio on D1 was highest in T4; while n-6/n-3 was highest in T1; and n-3 was highest in T3. On D8, the n-3 was highest in T1 (P < 0.05). Results of the current study show that supplementation of M. oleifera leaf at additive levels of up to 5 percent of the bird’s DMI does have the potential to influence the bird performance without any detrimental effects on nutrient utilization, bird health, bone strength and/or meat quality, which can be concluded that MOLM enhanced the bird’s genetic potential for optimal productivity.]]> Thu 13 May 2021 01:45:03 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11890 Thu 13 May 2021 01:29:36 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11120 Thu 13 May 2021 01:05:45 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11678 Thu 13 May 2021 00:57:08 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:11368 Thu 13 May 2021 00:30:28 SAST ]]>
