Background and Objective: The endophytes are the fungi or bacteria that live within a plant in a symbiotic relationship. This study aimed to investigate the effect of isolated bacterial endophytes from Allium jesdianum on some bacterial pathogens such as Staphylococcus aureus, Escherichia coli as well as pathogenic fungi, including Trichophyton mentagrophytes and Candida albicans. Materials an...

A new series of 2-(5-nitro-2-heteroaryl)-1,3,4-thiadiazole derivatives, including nitro furan, nitro thiophene and nitro imidazole, were synthesized and screened in vitro for their inhibitory activity against eight bacterial strains. The results showed that most of the synthesized compounds were active against Gram-positive bacteria, determined by MIC method. Among them, compounds <str...

a new series of transition metal complexes of co(ii), ni(ii), cu(ii) and zn(ii), has beensynthesized from the knoevenagel condensate schiff base ligand(l) derived from β-ketoanilideand furfural with o-phenylenediamine and diethylmalonate. structural features were determinedby spectral and analytical techniques. square-planar geometry has been adopted by thecomplexes except cobalt complex which ...

conclusions the study results showed that stimulation of the american cockroach’s immunity system lead to production of antibacterial proteins and peptides which had inhibitory effect on the bacteria, depending on the bacterial strains and their sensitivity. likely this feature of insects can be used as therapeutic strategies to produce natural antimicrobial compounds against the pathogenic bac...

infective endocarditis is one of the most severe complications of parenteral drug abuse. the outstanding clinical feature of infective endocarditis in intravenous drug abusers is the high incidence of right-sided valve infection, and the tricuspid valve is involved in 60% to 70% of the cases. we herein report a case of isolated pulmonic valve infective endocarditis with a native pulmonary valve.

background: yogurt is one of the most popular food diets with refreshing taste, nutritional, and health benefits. the objective of this study was to investigate the effect of three herbal essential oils (eos) including peppermint, basil, and zataria on viability of the probiotic bacteria in yogurt samples and to evaluate the antimicrobial activities of the produced probiotic yogurts against esc...

background: multidrug resistant enterobacteriaceae which was confined to the hospital environments is now emerging in the domestic food related environments as well. the main objective of the present study was to investigate the prevalence of antibiotic resistant enterobacteriaceae in the domestic food related environments.  methods: resistance to ampicillin, chloramphenicol, ciprofloxacin, gen...

actinomycetes were isolated from marine sediment samples collected from the east coast of chennai, tamil nadu, india. well diffusion and agar plug methods were used for the evaluation of antibiotic production by these isolates against drug resistant methicillin- resistant staphylococcus aureus (mrsa) and vancomycin resistant enterococci (vre). the potential isolate vitbrk2 was mass cultured for...
