The lack of antibiotics with a novel mode of action associated with the spread of drug resistant bacteria make the fight against infectious diseases particularly challenging. A quinoline core is found in several anti-infectious drugs, such as mefloquine and bedaquiline. Two main objectives were set in this work. Firstly, we evaluated the anti-mycobacterial properties of the previous quinolines 3, which have been identified as good candidates against ESKAPEE (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter spp. and Escherichia coli) bacteria. Secondly, a new series 4 was designed and assessed against the same bacteria strains, taking the pair of enantiomers 3m/3n as the lead. More than twenty compounds 4 were prepared through a five-step asymmetric synthesis with good enantiomeric excesses (>90%). Interestingly, all compounds of series 3 were efficient on M. avium with MIC = 2–16 µg/mL, while series 4 was less active. Both series 3 and 4 were generally more active than mefloquine against the ESKAPEE bacteria. The quinolines 4 were either active against Gram-positive bacteria (MIC ≤ 4 µg/mL for 4c–4h and 4k/4l) or E. coli (MIC = 32–64 µg/mL for 4q–4v) according to the global lipophilicity of these compounds.

An exploratory study based on laboratory experiment was carried out to determine the antibacterial effect of Dimethyl sulfoxide (DMSO) extract of Aloe vera leaf gel (DAE) against standard strains of Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumoniae in the Department of Pharmacology & Therapeutics in collaboration with the Department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh. DMSO extract was used in five different concentrations (100, 200, 300, 400 and 500 μg/ml). Dose dependent inhibitory effect was seen against the test organisms using disc diffusion method. Zone of inhibition (ZOI) were 8 mm, 13 mm, 15 mm, 16 mm and 21 mm against S. aureus; 0 mm, 8 mm, 13 mm, 15 mm and 18 mm against P. aeruginosa; 8 mm, 11 mm, 13 mm, 16 mm and 20 mm against E. coli; 0 mm, 9 mm, 12 mm, 14 mm and 18 mm against K. pneumoniae at 100, 200, 300, 400 and 500 μg/ml respectively. The minimum inhibitory concentration (MIC) was assessed by broth dilution technique. The MICs of DAE for S. aureus, P. aeruginosa, E. coli and K. pneumoniae were 300 μg/ml, 400 μg/ml, 400 μg/ml and 450 μg/ml respectively. From the study it was observed that DMSO extract of Aloe vera leaf gel possesses antibacterial effect against the test pathogens. The findings highlight the need for further extensive study to detect and isolate the biologically active ingredients present in the Aloe vera leaves which are responsible for antibacterial effect. Hopefully, that would lead to the discovery of new and more potent antimicrobial agents originated from Aloe vera. Mediscope Vol. 7, No. 2: July 2020, Page 67-74

Background: Using smoke from burning donkey dung has been popular in the treatment of many diseases in Iran. Objective: This study aimed to investigating the antimicrobial properties of donkey dung smoke on multi-drug resistant (MDR) bacteria isolated from urinary infection. Materials and Methods: First, 300 and 200 urine samples were collected from pregnant and non-pregnant women in Isfahan, Iran. Then in each group, 100 bacterial isolates including Escherichia coli, Klebsiella pneumonia, Proteus vulgaris, Staphylococcus epidermidis, Staphylococcus aureus, Pseudomonas aeruginosa, and Staphylococcus saprophyticus were isolated. Antibiotic resistant protocol was determined by antibiogram test. Donkey dung was sterilized, disintegrated, and heated. The smokes were concentrated in n-hexane solvent (65%) and were collected after evaporation of the solvent. Finally, the antibacterial activities of the concentrations of 0.25, 0.5 and 1 mg/mL of the smokes were detected using disk diffusion and macrodilution methods. Results: The most abundant MDR isolates causing urinary infections in pregnant and non-pregnant women was Escherichia coli. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of donkey dung smoke on MDR isolates from pregnant women were 0.25 mg/mL and 0.5 mg/mL, respectively. In the case of MDR isolates in non-pregnant women, the MIC of the smoke on Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus was 0.25 mg/mL, and the MBC on these isolates was 0.5 mg/mL. Conclusion: The smokes from donkey dung investigated in the present study have suitable potentials for controlling the infections after In vivo analysis.

Introduction: The bacteria colonising the oral cavity and the dentures acquire drug resistance due to frequent usage of antibiotics systemically and application of mouth rinses and denture disinfectants locally. These multidrug resistant bacteria pose potential threat to the health of the patient as infections caused by them do not respond to conventional antibiotics. Aim: The present study aims at detecting the drug resistant bacteria in patients who wear complete dentures. Materials and Methods: The study is a descriptive study and follows laboratory invitro study design involving 30 complete denture patients. Swabs were collected from their oral cavity as well as complete denture surfaces. Antibiotic sensitivity tests were performed for the following bacteriae namely Viridans streptococci species, Staphylococcus aureus, Klebsiella pneumoniae and E.coli. Isolation of the bacteria were done by means of selective media and subjected to biochemical tests. The 16S rRNA sequencing was done to ascertain the microorganisms by which 20 isolates of each of the selective bacteria were obtained. The bacteria were classified as sensitive, intermediate sensitive and resistant based on antibiotic sensitivity tests. Those isolates which exhibited Multi-Drug Resistance (MDR) were visualised using SEM. Results:Viridans streptococci spp. (40%) and Staphylococcus aureus (25%) isolates were resistant to Amoxiclavulinic acid and Methicilin, whereas Klebsiella pneumoniae (30%) and (30%) E.coli isolates were most resistant to Cefotaxime and Doxicilin. Conclusion: Drug resistant bacteria have been identified from complete dentures and oral cavity in the present study. Antibiotic sensitivity tests, 16S rRNA sequencing and SEM are vital investigative tools to detect and to visualise drug resistant bacteria. Cell density, Extracellular Polymeric Substances (EPS) and capsule could be important factors for providing drug resistance.

ABSTRACT Endophytic fungi are fungi that live in plant tissues and do not harm these plants. Endophytic fungi can produce compounds that have the potential as antibacterial. This study aimed to examine the antibacterial effects of endophytic fungi isolated from the lemongrass (Cymbopogon citratus) against Staphylococcus aureus and Escherichia coli bacteria. Lemongrass is used to inhibit or kill pathogenic bacteria because it contains essential oils that function as an antifungal and antibacterial against several pathogenic bacteria such as Staphylococcus aureus and Escherichia coli. The laboratory experiment method tested the antibacterial activity of endophytic fungi isolates obtained from lemongrass (Cymbopogon citratus) against Staphylococcus aureus and Escherichia coli using hole / well method. From the results of the study, four endophytic fungi were isolated from the roots and leaves of lemongrass (Cymbopogon citratus). Antibacterial results showed that endophytic fungi extract isolated from lemongrass plants was more effective in inhibiting Staphylococcus aureus compared to Escherichia coli bacteria. In Staphylococcus aureus bacteria the average inhibitory value is 5-9 mm while in Escherichia coli bacteria the average inhibitory value is only 3 mm. Endophytic fungi from lemongrass roots have a better antibacterial effect compared to endophytic fungi from lemongrass leaves. Conclusion, endophytic fungi isolated from the roots and leaves of lemongrass (Cymbopogon citratus) have an antibacterial effect on the growth of S. aureus bacteria and are not effective against E. coli bacteria. This endophytic fungus isolate is more active against Gram positive (+) bacteria and less active against Gram negative (-) bacteria. Keywords: Lemongrass plants, Endophytic Fungi, Antibacterial Activity, Staphylococcus aureus,  Escherichia coli. ABSTRAK Jamur endofit ialah jamur yang hidup di dalam jaringan tumbuhan dan tidak membahayakan tumbuhan tersebut.

Extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL), a family of bacteria that includes Escherichia coli, have emerged as a global health threat. This study examined risks associated with carriage of third-generation cephalosporin-resistant (3GC-R) E. coli, including ESBL-producing, multidrug-resistant, and extensively drug-resistant (XDR) strains in children living in semirural parishes of Quito, Ecuador. We conducted a longitudinal study with two cycles of sampling (N = 374, N = 366) that included an analysis of child fecal samples and survey questions relating to water, sanitation, and hygiene, socioeconomic status, household crowding, and animal ownership. We used multivariate regression models to assess risk factors associated with a child being colonized. Across the two cycles, 18.4% (n = 516) of the 3GC-R isolates were ESBL-producing E. coli, and 40.3% (n = 516) were XDR E. coli. Children living in households that owned between 11 and 20 backyard animals had an increased odds of being colonized with XDR E. coli (odds ratio [OR] = 1.94, 95% confidence interval [CI]: 1.05–3.60) compared with those with no animals. Households that reported smelling odors from commercial poultry had increased odds of having a child positive for XDR E. coli (OR = 1.72, 95% CI: 1.11–2.66). Our results suggest that colonization of children with antimicrobial-resistant E. coli is influenced by exposure to backyard and commercial livestock and poultry. Future studies should consider community-level risk factors because child exposures to drug-resistant bacteria are likely influenced by neighborhood and regional risk factors.

A resistência bacteriana a antibióticos tornou-se mundialmente um sério problema de Saúde Pública atingindo milhares de pessoas. Assim, vê-se a necessidade de buscar formas alternativas no combate das mesmas.  Portanto, essa pesquisa objetivou verificar o efeito antimicrobiano do extrato da Annona muricata L. frente a cepas ATCC de Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa e Staphylococcus aureus. Realizou-se a coleta do material e a obtenção dos extratos, posteriormente houve a preparação das cepas bacterianas para os testes de suscetibilidade. Os testes prosseguiram em três etapas: extratos brutos, extratos fracionados quimicamente e testes com diluições seriadas.  Verificou-se atividade antibacteriana da graviola frente a todas as cepas testas sendo o resultado mais significante referente ao extrato bruto do fruto frente a cepa da E. coli com halo igual a 22mm. Em relação aos testes com os extratos já purificados, as frações provenientes do fruto tiverem ação mais relevantes. A fração de Hexano correspondeu em resultados mais expressivos obtendo halos igual a 28mm, 26mm e 37mm frente as cepas de E. coli, K. pneumoniae, e S. aureus respectivamente. Quanto aos testes relacionados as diluições seriadas observamos que a partir da diluição de 1/10 os extratos já não possuíram nenhuma atividade inibitória sobre as bactérias em estudo. Contudo, esses resultados demonstram o potencial do extrato da graviola, em especial do fruto, como fonte de compostos antibacterianos. No entanto, é válido continuar pesquisas mais avançadas com a Annona muricata.
