CHARACTERIZATION OF MULTI-DRUG RESISTANCE LIVESTOCK ACQUIRED METHICILLIN RESISTANT STAPHYLOCOCCUS AUREUS (LA-MRSA) ISOLATES FROM DIFFERENT SWINE FARMS IN ENUGU METROPOLIS, NIGERIA

Aim and Objective: Globally, livestock animals, particularly swine, calves and poultry are colonized by Livestock acquired methicillin resistant Staphylococcus aureus (S. aureus) (LA-MRSA). This study was aimed at screening for multi-drug resistant in LA-MRSA strains isolated from swine from selected swine farm within Enugu metropolis. Methods: A total of 307 pig nasal swabs samples were collected, from farm A (76), farm B (116) and from C (108) in Enugu metropolis. Then within 1 hour of collection, samples were transferred to the Caritas University Microbiology Laboratory unit for bacteriological analysis using a standard microbiological isolation and identification protocol. Isolated S. aureus and LA-MRSA strain were phenol-typing screened and identified for MRSA using Kirby-Bauer disc diffusion method with 1 μg oxacillin/30μg cefoxitin antibiotic Disc and Tetracycline Disk Test respectively. Antibiogram studies of LA-MRSA against several antibiotic discs and multiple antibiotic resistance indexes were determined. Results: Results showed overall isolation rate of 76.2 % S. aureus comprising of 90.5 %, 80.3 % and 62.9 % in Farm B, Farm A and Farm C respectively, total MRSA detection rate of 125 (40.7%) comprising Farm A 50.0 %, Farm B 46.6 %, Farm C 30.6 %.  LA-MRSA were identified in 84(27.4%) of swine with high proportion of 29(38.2 %) in Farm A followed by Farm C30(27.8%) and Farm B 25(21.6 %). LA-MRSA from Farm A Nursery: 27.3%, Weaning 0.0 %, Grower 77.0 % while Farm B Nursery 24.1 %, Weaning 0.0 %, Grower 7.3 %, finisher 100 % and Farm C Nursery 28.0 %, Grower 34.5 % and finisher 53.3 %. LA-MRSA isolates exhibited a significantly (p≤0.05) high % resistance within the range of 50-100 % against tetracycline, erythromycin, cefotaxime, clindamycin, Trimethoprim-Sulfamethoxazole and exhibit MDR with MARI value ≥0.3 but were susceptible to ciprofloxacin 77.8 %, amikacin 100 % and imipenem 100 %. Conclusion: LA-MRSA strains increased levels of MDR phenotype suggest that the emergence of LA-MRSA in swine up keeping could be promoted through veterinary antibiotics. Thus, to prevent antimicrobial resistance in both animals and humans, joint cross-examination of multi-resistant livestock acquired S. aureus, with an incorporated ‘One Health’ advancement are needed for effective curbing and control measures for LA-MRSA infections.                           Peer Review History: Received: 1 September 2022; Revised: 12 October; Accepted: 4 November, Available online: 15 November 2022 Academic Editor: Prof. Dr. Gorkem Dulger, Duzce University, Turkey, [email protected] Received file:                             Reviewer's Comments: Average Peer review marks at initial stage: 5.5/10 Average Peer review marks at publication stage: 7.0/10 Reviewers: Dr. U.

PHYTOCHEMICAL SCREENING AND ANTIDIABETIC ACTIVITY OF METHANOLIC EXTRACT OF CAYLUSEA ABYSSINICA LEAVES

Introduction:  Controlling type 2 diabetes with a treatment having no side effects remains a challenge for researchers even if the side effects are reduced and there may be a chance for reduced adverse reactions or severe side effects due to drug interaction. These interactions could result from concurrent use of dietary supplements or pharmacological therapy in addition to the medications. The current reading's objective was to assess the qualitative and quantitative phytochemical analyses, and antidiabetic potentials of methanol leaf extract of Caylusea abyssinica (C. abyssinica) in diabetic rats. Methods:  The qualitative and quantitative phytochemical analyses of total alkaloids phenol, and flavonoids were determined using the well-known test procedure outlined in the literature. The obtained C. abyssinica methanol leaf extract was used to examine in vitro anti-diabetic activity (α-Amylase inhibition), oral acute toxicity, and in vivo anti-diabetic activity against streptozotocin-induced diabetes rat model. Alkaloids, carbohydrates, reducing sugars, saponins, phenolic compounds, glycosides, tannins, and flavonoids were all established in the samples after phytochemical examination. Results: The amount of phenolics in the methanol leaf extract was (295.50 mg/g), with flavonoids coming in second (136.66 mg/g) and alkaloids coming in third (11.23 mg/g). The extract's ability to inhibit α-amylase was investigated. The study's findings show that the chosen plants had significant in vitro anti-diabetic effect. Up to 2000 mg/kg given over 14 days, the methanol extract's acute toxicity trials did not reveal any harmful effects. Rats were given streptozotocin (60 mg/kg; i.p.) to induce diabetes, and glibenclamide (500 mcg/kg body weight) was utilized as the usual medication. Body weight, HDL, total protein, SGOT, SGPT, cholesterol, blood sugar levels, and triglycerides were all assessed in this study. Comparing diabetic rats to normal (control) rats, blood sugar and total protein, SGOT, SGPT, cholesterol levels, and triglyceride concentrations were all considerably (p<  0.001) reduced after oral administration of methanol extract of C. abyssinica at doses of 100 and 200 mg/kg and increased the level of HDL and body weight. Conclusion: As a result of the aforementioned findings, it can be said that C. abyssinica methanol leaf extract significantly reduces blood sugar levels in streptozotocin-induced diabetic rats.                       Peer Review History: Received: 5 November 2022; Revised: 11 December; Accepted: 8 January 2023, Available online: 15 January 2023 Academic Editor: Dr. Tamer Elhabibi, Suez Canal University, Egypt, [email protected] Received file:                             Reviewer's Comments: Average Peer review marks at initial stage: 5.0/10 Average Peer review marks at publication stage: 7.0/10 Reviewers: Dr. Sangeetha Arullappan, Universiti Tunku Abdul Rahman, Malaysia, [email protected] Prof. Hüsniye Kayalar, Ege University, Turkey, [email protected] Similar Articles: EFFECT OF THE AQUEOUS EXTRACT OF CLERODENDRUM THOMSONIAE LINN (VERBENACEAE) LEAVES ON TYPE 2 DIABETIC WISTAR RATS INDUCED BY THE MACAPOS1 TYPE DIET AND DEXAMETHASONE ANTIDIABETIC AND ANTIHYPERLIPIDEMIC ACTIVITY OF DRACAENA CINNABARI BALF.
