The remaining soil microaggregates (< 0.250 mm) were then mixed with high quality Vachellia karoo leaf litter (C/N = 23.8) and low quality Zea mays stover (C/N = 37.4) and incubated at 23oC for 30 weeks. Jars were arranged as a 7 × 3 factorial laid in completely randomized design (CRD) with three replicates. Data was repeatedly measured at 1, 3, 8, 14, 23 and 30 weeks after incubation: to determine the stabilization of SOM by fractionating the soil particulate organic matter (POM), rate of soil macroaggregate re-formation and influence of litter quality on splash soil erosion along a decomposition continuum. Free light fractions (Free LF), coarse particulate organic matter (CoPOM) and fine particulate organic matter (FiPOM) within macroaggregates (> 250 μm) decreased exponentially from week 1 to 30 and were significantly (p < 0.05) influenced by litter quality × soil horizon × time interactions. A similar trend for FiPOM fractions in macroaggregates was observed in the 53-250 μm microaggregates (p < 0.05). The greatest influence on changes in POM fractions occurred within the first 3 weeks of incorporation. Both V. karroo leaf litter and Z. mays stover significantly stabilized the macroaggregates within the first 3 weeks after incubation. Cumulative macroaggregates yields, mean weight diameter (MWD), percentage water stable aggregates (%WSA) and whole soil stability index (WSSI) in litter amended soils increased up to week 8 of incubation and thereafter gradually declined in all soils. An increase in macroaggregation resulted in increased MWD, WSSI values and large and small aggregates distribution. Aggregation was significantly higher in soils with higher clay content than sand content, suggesting that soil texture was highly influential in litter decomposition. Rate of litter decomposition was influenced by soil type × time interactions which determined extent and macroaggregation dynamics along a decomposition continuum. The amount of splashed sediments was determined from each soil horizon at 360 mm h-1 simulated rainfall intensity applied as either single 8minute rainstorm (SR) or 4 × 2minute intermittent rainstorms (IR) separated by a 72 h drying period. Results showed a reduction in splashed sediments under IR and SR storms in litter-amended soils during the first 8 weeks of incubation with gradual increase thereafter. More sediments were splashed under IR than SR and litter quality had no influence on splashed sediments per soil horizon. Soil horizons profile with more clay than sand particles enhanced the litter effects on the soil resistance against detachment. The amount of SOC loss was influenced by primary particle size distribution and initial SOC content of the soil. Rainfall pattern and the initial SOC content were the main factors by which different soils influenced SOC loss. More rainstorm patterns should be investigated on these soils.]]> Wed 12 May 2021 16:05:04 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39080 Wed 12 May 2021 15:55:18 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40110 Wed 12 May 2021 15:04:41 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40152 Wed 12 May 2021 15:01:44 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40406 Wed 12 May 2021 14:50:52 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40607 0.05) and values of >0.20 were recorded in 40 percent (108/277) of all the isolates. The resistant genes ampC, blaOXA, tetA, tetM, dfr1, sul1, sul2, ermB, nptII and strA were detected in two or more Vibrio isolates while the SXT intergrase was detected only in one isolate. Seven of the 18 extreme drug resistant isolates possessed 1–3 plasmids of 1.5–10 kb range. A total of 321 presumptive Staphylococcus aureus isolates were recovered by culture out of which 202 (62.9 percent ) were identified as S. aureus by PCR. Of these, 33 (16.3 percent ) strains were mecA positive while the rest, 169 (83.7 percent ) were mecA negative. The sensitivity and specificity of MRSA detection by use of cefoxitin disc (30 μg) test was 93.9 percent and 91.7 percent , that for oxacillin screen agar test (6 μg/mL) was 81.8 percent and 92.3 percent while that of BrillianceTM MRSATM 2 agar was 87.9 percent and 94.1 percent respectively. Staphylococcal enterotoxin SEE was detected in 12.1 percent (4/33) of total strains followed by SEA 3.0 percent (1/33), and SEC 3.0 percent (1/33). SEB and SED were absent. Six of the isolates had the PVL gene, giving a prevalence of 18.2 percent . The most frequently detected SCCmec type was SCCmec type III (17/33; 51.5 percent ), closely followed by SCCmec subtype IVc (10/33; 30.3 percent ) and the least were SCCmec types I and II with only 3.0 percent (1/33) each. The rest four (4/33; 12.1 percent ) did not belong to any of the above types and were therefore considered to belong to other subtypes of SCCmec type IV not tested in the study. For antibiogram patterns, 12 (36.4 percent ) strains were resistant to doxycyline, 10 (30.3 percent ) to trimethroprim-sulfamethoxazole, 9 (27.3 percent ) to tetracycline and only 1 (3.0 percent ) strain was resistant to ciprofloxacin. Nineteen (57.6 percent ) of the MRSA strains had vancomycin MIC of ≤ 2 μg/mL, 4 (12.1 percent ) with MIC range of 4-8 μg/mL, and 10 (30.3 percent ) with values ≥ 16 μg/mL. Overall, 27 (91.percent) isolates showed simultaneous resistance to 3 or more antibiotics. The resistant genes tetM, tetA, ermB, BlaZ femA were detected in two or more strains resistant to various antimicrobials. Resistance to rifampicin was not caused by mutations in the rpoB gene. Conclusions: To the best of our knowledge, this study is the first study reporting a broad, and diverse bacteria flora of skin, gill, and gut of the South African dusky kob as well as the first study on human pathogenic vibrios, and MRSA from marine finfish especially those from recirculatory aquaculture systems. Also, our study revealed that Vibrio species with pathogenic potential are present in marine dusky kob and its environs. Dusky kob is contaminated with CA- MRSA and HA- MRSA that may cause difficult to treat infections with regular antibiotics. Some of the MRSA strains contained toxins that can cause food-borne gastroeneteritis. The present study revealed that MRSA and Vibrio species are potential reservoirs for antibiotic resistant genes, which could be disseminated to other bacterial species probably through plasmids, a public health risk.]]> Wed 12 May 2021 14:37:33 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40606 Wed 12 May 2021 14:20:28 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:40514 Wed 12 May 2021 14:11:23 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:41374 Wed 12 May 2021 13:47:51 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:27540 Tue 07 May 2024 11:36:29 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:31345 Thu 13 May 2021 17:02:06 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:35249 0.05).

Furthermore sex of animal influenced significantly (P < 0.05) the DM, ADF, NSC and NDF digestibilities. Lablab and Cowpea did not influence (P > 0.05) individual VFA molar concentrations in both sexes. However, animals fed Lablab had significantly higher butyrate concentrations (P < 0.05). Lablab and Cowpea forages significantly lowered (P > 0.05) enteric methane production in goats compared to a concentrate diet, and this was related to animal activity. Animals produced significantly more (P < 0.05) methane gas when ruminating than feeding or just standing. The average methane produced each year was lower but not significant (P > 0.05) for animals fed Cowpea than Lablab (4.602kg CH4, vs. 4.719kg CH4) when expressed per year.

Virulence factors are important for the pathogenesis of H. pylori. All the 48 clinical isolates were glmM (140 bp) positive and cagA was detected in 97.9 percent of the test isolates. The vacA gene was detected in all isolates but with different subtypes. The vacA allelic combination s1m1 was detected in 75 percent of the test isolates and s1m2 allelic combination was detected in 16.7 percent of the test isolates while the combination s2m2 was detected in 8.3 percent of the test isolates. None of the test isolates possessed the allelic combination s2m1. When H. pylori multiplication was monitored under acidic conditions in the presence of anti-urease active compounds, it was revealed that anti-urease active compounds in honey are capable of inhibiting the normal multiplication of H. pylori strains that are cagA positive, vacA positive and drug resistant. The GC-MS analysis showed that Fleures honey (urease I percent = 67.8 – 68.5 percent) and Gold Crest honey (urease I percent = 50.9 percent – 53.3 percent), all petroleum ether extracts had 27 and 26 volatile compounds. The hexane extract of Manuka honey (urease I percent = 50.0 – 53.2) had 43 compounds detected. The chloroform extract of Q Bee (urease I percent = 64.2 – 66.2 percent) had 13 volatile compounds detected. All the volatile compounds considered as representative samples of GC-MS analysis had a spectral matching ≥ 90 percent with the NIST11 library. However, the majority of compounds that were detected by LC-MS in representative honey extracts include vardenafil, urapidil, hydrocortisone, e.t.c which are drugs commonly used in the treatment of different ailments or infections that affect human beings. In addition, two xi drugs, sulfaquinoxaline and hydroxyquinoline which are used in veterinary medicine and antiseptic, disinfectant and pesticide applications in agricultural activities were detected in Little Bee honey. We therefore conclude that inhibition of urease has a bactericidal effect on drug resistant, cagA positive and vacA positive H. pylori strains growing under acidic environment.]]> Thu 13 May 2021 05:55:10 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:32562 Thu 13 May 2021 05:43:41 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29671 Thu 13 May 2021 05:30:42 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:37199 Thu 13 May 2021 05:26:56 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28088 Thu 13 May 2021 05:24:05 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29178 Thu 13 May 2021 05:06:43 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39464 Thu 13 May 2021 04:49:56 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:31624 Thu 13 May 2021 04:33:23 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:33423 Thu 13 May 2021 04:20:57 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:34353 Thu 13 May 2021 03:53:44 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28507 Thu 13 May 2021 03:52:09 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:34306 Thu 13 May 2021 03:42:08 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:33091 Thu 13 May 2021 03:27:58 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28534 Thu 13 May 2021 02:40:53 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:33400 1 mg/ml.

Based on the Bastos criterion of toxicity indices of the lethality test, all the plant fractions demonstrated cytotoxicity effect, although the degree of their toxicity varied among the plants used. Standard spectrophotometry assays were used to quantify the phytochemical contents and to determine the antioxidant potentials of the cultivated and wild A. amatymbica. The results revealed different levels of phytochemicals with corresponding antioxidant activities. The wild extracts had higher phytochemical contents in most of the assays than cultivated extracts. Total phenol in the wild extracts ranged from 32.30±3.43 to 117.8±8.45 mg GAE/g with the acetone extracts having the highest content while the water extracts was the least. The range in the total phenol of the cultivated species was 66.46±5.29 to 98.44±6.08 mg GAE/g with the methanol extracts having the highest content while water extracts was the least. The flavonoids content ranged from 55.01±6.51 to 99.09±7.20 mg QE/mg and from 48.65±7.74 to 67.32±4.1 mg QE/mg for the wild and cultivated plants, respectively. The alkaloids contents ranged from 14.70±0.04 to 17.80±0.015 percent in the wild species while it ranged from 11.98±0.14 to 13.21±0.06 percent in the cultivated species. The wild species also showed higher antioxidant activities in most of the assays evaluated. The study revealed successful cultivation of the wild species of Alepidea amatymbica using fragments from the rhizome. The micromorphological study of both the wild and cultivated species showed minimal differences in the helical thickening of the walls in the xylem vessels and starch grain accumulation pattern. Although herbal medicine practitioners believe that cultivated species are not potent, however this study revealed some levels of phytochemicals contents and antioxidant activities which are comparable to the wild species. Cultivation is a major strategy in conserving nature and their resources. Hence, the successful domestication of A. amatymbica would help in reducing the pressure on the wild species while also meeting their medicinal demands purposes, utilisation and conserving for future generations.]]> Thu 13 May 2021 02:38:40 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:34307 0.05) effect on biomarkers of liver and renal damage.

Enzyme based in-vitro antiobesity evaluation of the aqueous and ethanolic extracts of K. africana, V. mespilifolia and their combination revealed that the ethanol extracts of both plants and their combination exhibited moderate inhibitory activities against α-amylase, α- glucosidase and pancreatic lipase. However, the standards used for the various inhibition assays exhibited much higher inhibitory actions when compared to any of the extracts. This suggests that the mechanism by which these two plants and their combination exert anti-obesity effects are probably not by inhibition of key enzymes of carbohydrate and fat metabolism.]]> Thu 13 May 2021 02:36:17 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:35015 Thu 13 May 2021 02:09:16 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:30769 Thu 13 May 2021 01:55:45 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28487 Thu 13 May 2021 01:54:36 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28344 Thu 13 May 2021 01:31:32 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:32743 Thu 13 May 2021 01:21:17 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:33431 Thu 13 May 2021 01:20:00 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29373 Thu 13 May 2021 01:12:50 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29593 Thu 13 May 2021 01:07:24 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39799 Thu 13 May 2021 01:07:05 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29180 Thu 13 May 2021 01:05:55 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:33250 Thu 13 May 2021 00:51:21 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:29092 Thu 13 May 2021 00:48:02 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28879 Thu 13 May 2021 00:48:00 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:33166 Thu 13 May 2021 00:20:06 SAST ]]> https://commons.ufh.ac.za/vital/access/manager/Repository/vital:28138 Thu 13 May 2021 00:04:32 SAST ]]>
