background escherichia coli o157:h7, vibrio cholerae, and salmonella typhimurium are pathogenic bacteria found in contaminated water and food. no assay method is currently available on simultaneous detection or identification of all the three pathogens. our aim was to develop a rapid and reliable method for this purpose. materials and methods a protocol for sample collection, and a pcr procedur...
Background and Aims: Influenza vaccination is one of the best way to prevent and control influenza worldwide. It is manufactured by WHO-licensed companies based on the WHO expertise committee annually. The aim of this study was partial quality control of the commercial human influenza vaccine 2008-9 and its matching with the circulating strains. Materials and Methods: The trivalent imported vac...
We evaluated the use of the molecular bacterial load (MBL) assay, for measuring viable Mycobacterium tuberculosis in sputum, in comparison with solid agar and liquid culture. The MBL assay provides early information on the rate of decline in bacterial load and has technical advantages over culture in either form.
GSQ1530 is a compound derived from a newly identified class of antibiotics referred to as heteroaromatic polycyclic (HARP) antibiotics. The aim of this study was to assess the in vitro antimicrobial activity of GSQ1530. By using an NCCLS broth microdilution assay, the activities of GSQ1530 and other antibiotics were coevaluated against 215 clinical isolates. The MICs at which 90% of isolates ar...
Objective(s): Pseudomonas aeruginosais a Gram-negative and aerobic rod bacterium that displays mucoid and non-mucoid phenotype. Mucoid strains secrete alginate, which is the main agent of biofilms in chronic P. aeruginosa infections, show high resistance to antibiotics; consequently, the biological disruption of mucoid P. aeruginosa biofilms is an attractive area of study for researchers. Algin...
The antibacterial activities of eight snake crude venom (Macrovipera lebetina obtusa, Pseudocerastes persicus, Pseudocerastes urarachnoides, Echis carinatus sochureki, Gloydius halys caucasicus, Naja (naja) oxiana, and two species of true sea snakes Enhydrina schistose and Hydrophis cyanocinctus) were assessed against five important standard pathogenic bacterial strains (Escherichia coli, ...
The aim of the present study was to develop a broad-range PCR based on bacterial 16S rDNA for use in the routine diagnostic clinical microbiology service. The optimization and validation of the assay for use on clinical specimens from normally sterile sites is described, and preliminary results are reported on the use of the assay in the clinical diagnosis of bacterial infection in 382 paediatr...
The chemical compound temephos (0,0,0',0'-tetrametyl-0,0'-thiodi-p-phenylene phosphorothioate) is an organophosphorous pesticide that has been used in Brazil since 1967 in control campaigns against the mosquito Aedes aegypti, the vector of dengue and yellow fever. We used single cell gel electrophoresis (SCGE), SOS/umu and Ames/Salmonella assays to test the toxicity and mutagenicity of temephos...
Biofilm formation is a process of bacterial attachment whereby they fasten irreversibly to biomaterial surface and lead unwanted phenotypic changes. The chief concern its prevent the harmful changes that follow accumulation bacteria on implants, so scientific community has made efforts. In this study, we attempted fabricate novel tissue engineering candidate biofilm desired by ideal biomaterial...
BACKGROUND Reliably distinguishing bacterial from viral infections is often challenging, leading to antibiotic misuse. A novel assay that integrates measurements of blood-borne host-proteins (tumor necrosis factor-related apoptosis-inducing ligand, interferon γ-induced protein-10, and C-reactive protein [CRP]) was developed to assist in differentiation between bacterial and viral disease. MET...
