Multi-drugresistant organisms refer tomicrobes that areresistant to the effects of antimicrobial drugs to which they were previously susceptible at therapeutic range. Objectives: This study investigates the combined effects of Alchornea cordifolia and Pterocarpus santalinoides leaves extracts against selected multi-drug resistant diarrhoegenic bacteria. Methods: Fresh plant seeds were collected from the plants, shade-dried, pulverized and extracted with methanol in a Soxhlet apparatus. Antibacterial activities of these plants were investigated using agarwell diffusion assay. The MIC and FIC of the extracts against test isolates were determined using agar well diffusion method and checkerboard assay respectively. The bactericidal effects of the extracts against the isolates were evaluated using Time-Kill Assay. Results: MIC values of methanolic extracts against drug resistant strains of Salmonella typhi , Shigella dysenteriae , Escherichia coli and Staphylococcus aureusranges from 6.25 µg/mL to 12.5 µg/mL. The combination of Alchornea cordifolia and Pterocarpus santalinoides extracts showed synergy at 8:2 and 4:6 combinations against S. aureus, Salmonella typhi and E. coli; at 7:3 combinations against E. coli ; at 6:4 and 3:7 combinations against S. aureus, Salmonella typhi , S. dysenteriae ; at 5:5 combinations against all the test isolates; at 2:8 combinations against S. aureus , S. dysenteriae and E. coli but additive against Salmonella organisms; at 1:9 combinations against S. aureus and Salmonella organism. Conclusion: The methanol extracts of the plants at combinations 5:5 is synergistic against all the tested multi-drug resistant diarrhoegenic bacteria. Combination of Salmonellaand A. cordifolia showed potentials of synergism against the test isolates. The detection of synergy suggests presence of antibiotic resistance modifying compounds in those extracts.","PeriodicalId":8517,"journal":{"name":"Asian Journal of Biomedical and Pharmaceutical Sciences","volume":"13 1","pages":"10-18"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72928520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results, derived from this methodology, show that this ointment is homogeneous, weakly aromatic and acidic (pH : 5,6), rich in dissolved and mineral substances, no lethality was observed up to the dose of 3200 mg/kg in acute. Also, the aqueous extract of this plant has an abundance of Flavonoids. In addition, the healing effect of Ageratum conyzoides L. ointment was evaluated on deep wounds in Wistar rats. The planimetry results and measurements made over twentysix (26) days proved that the ointment at 4 and 8 g/rat weight; Madecassol® at 400 mg/kg (reference product) significantly reduced the mean area of the deep wounds in Wistar rats compared to the negative controls. In addition, the aqueous extract of Ageratum conyzoides L. at the dose of 5,5 ml/kg administered in vitro on cell model wounds created by scraping the cell web, significantly reduces the wound in 24 hours. In addition, at the dose of 11 ml/kg this scarring is complete, there is no visible wound trace. This reflects the presence of a cell thrust at the level of the scratch compared to the control lot, whose wound remained almost gaping.

The morbidity and mortality rate of bacteremia due to Providencia species could be high, especially among the elderly and those with pre-existing medical conditions. This study was aimed at determining the occurrence of multidrug resistance phenotypes in clinical isolates of Providencia rettgeri using both phenotypic and genotypic techniques. Methods: Clinical isolates were identified to be isolates of P. rettgeri using standard microbiological and biochemical techniques; and these were characterized with respect to antibiotic resistant patterns. Overall, 143 clinical isolates of non-duplicate P. rettgeri isolates were bacteriologically recovered from the clinical specimens which included blood/wound swab samples (n=108) and swabs from surgical instruments and suction devices (n=35). Antimicrobial susceptibility test (AST) was done using the modified Kirby-Bauer disk diffusion techniques as per the Clinical Laboratory Standard Institute (CLSI) criteria. The isolates were tested phenotypically for ESBL production by the double disk synergy test (DDST) method and the β-lactamase genes were identified using polymerase chain reaction. The strains were sequenced with ABI3500XL analyzer with a 50 cm array, using POP7. Sequences data generated were analyzed with Geneious version 9. 0. 5. Results: The result of AST showed that Providencia rettgeri isolates were resistant to ceftazidime, cefotaxime, ampicillin and tetracycline. Based on the DDST method, some of the Providencia rettgeri isolates were phenotypically confirmed to be ESBL positive (11%) and MBL positive (6%). The results of the molecular analysis showed that the P. rettgeri isolates harbored SHV genes (n=6; 12. 5%) which mediates ESBL production. However, none of the isolates harboured the CTX-M or TEM gene. Conclusion: Our study shows that the P. rettgeri isolates analyzed were multidrug resistant, and they also harbour some important phenotypes and/or genotypes that mediate the production of ESBL (extended spectrum beta-lactamase). This is the first report of ESBL detection in clinical isolates of P. rettgeri in Imo state, southeast Nigeria.","PeriodicalId":8517,"journal":{"name":"Asian Journal of Biomedical and Pharmaceutical Sciences","volume":"38 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90458048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
