, in this study 77 and 86 bacterial strains were isolated from faeces of healthy and diarrhoeic dogs respectively. all salmonella isolates were confirmed by per method using specific inva genes. antibacterial activity of 8 routine antibiotics including tylosin, gentamycin, kanamycin, neomycin, tetracycline, oxytetracycline, chloramphenicol and sulfadiazine on the isolated bacteria was evaluated...

Kola nut (Cola nitida) is chewed in many West African cultures and it used ceremonially, industrially, medicinally economically. The aim of this study was to assess the phytochemical properties antibacterial activity Cola nitida seeds. seeds were purchased, dried then powdered for screening extraction. Ethanol aqueous (hot water) extracts study. each extract at 30 mg/ml 60 tested on four bacter...

Vi capsular polysaccharide production is encoded by the viaB locus, which has a limited distribution in Salmonella enterica serovars. In S. enterica serovar Typhi, viaB is encoded on a 134-kb pathogenicity island known as SPI-7 that is located between partially duplicated tRNA(pheU) sites. Functional and bioinformatic analysis suggests that SPI-7 has a mosaic structure and may have evolved as a...

BACKGROUND Our present study was conducted to characterize the phytoconstituents present in the aqueous extract of Momordica charantia and evaluate the antimicrobial efficacy of silver-extract nanoparticles (Ag-Extract-NPs). METHODS Silver nanoparticles (AgNPs) were prepared by reducing AgNO3; and NaBH4 served as reducing agent. After screening of phytochemicals; AgNPs and aqueous extract wer...

statement of problem: surface disinfection is an important aspect of infection control in dentistry. a new generation of quaternary ammonium components (qacs) is gaining popularity as high-level disinfectants. two types of qac sprays, uniseptaquick and solarsept, are being widely used by iranian dentists. purpose: the aim of this study was to evaluate the clinical efficiency of unisepta quick a...

Comparison of the rates of motility through a semisolid medium of 16 common Salmonella sp., 14 Escherichia coli serotypes, 4 Arizona strains, 2 Escherichia freundii (Citrobacter) isolates, 2 Proteus sp., and 2 Pseudomonas sp. revealed the following. (i) Very closely related bacteria could demonstrate markedly different rates of progression. (ii) All of the salmonellae tested advanced faster tha...

The antimicrobial effects of extracts of A. sativum and P. emblica, against pathogenic Staphylococcus aureus, Escherichia coli, Pseudomonas sp., Klebsiella sp, Salmonella typhi, Salmonella paratyphi, Salmonella sp., Bacillus subtilis, Bacillus cereus were investigated using the agar well and disc diffusion method. Aqueous extracts of A. sativum and P. emblica were more effective than ethanolic ...

Antimicrobial resistance of bacteria is one the biggest problems worldwide. Calotropis procera has been used in traditional and folk medicine due to presence different active compounds. The present study was conducted determine antimicrobial activity crude aqueous extracts against field isolates some gram negative positive bacteria. extract studied for its Escherichia coli, Staphylococcus aureu...

The occurrence and relative distribution of bacterial flora associated with the gut crab Callinectes amnicola, as well sediment water, from Badagry Epe Lagoons, were investigated. water samples Lagoon had highest total bacteria count 7.5±1.2 x 107 cfug-1, whereas lowest 3.6±0.5 cfug-1. analyzed plate counts C. included heterotrophic bacteria, coliform faecal which greater in than although these...

Current trends have suggested that the continuous use of chemical additives has carcinogenic effects on consumers. This instigated research into more organic ingredients such as plant parts which could serve potential replacement for these in food. study was therefore conducted to compare proximate and mineral compositions powder cinnamon bark clove buds collected from Cape Coast-Ghana, their e...
