BACKGROUND Isolated pulmonic valve endocarditis is a rare condition. The clinical and laboratory finding are not specific and experiences about that are limited. Most cases of that occur in children with congenital heart disease or in intravenous drug abusers and the main predisposing factor in adults is intravenous drug abuse. The most common pathogens are staphylococcus aurous and coagulase n...

background: lack of sanitation during storage, transmission, processing and consuming the food can cause early corruption and create economical losses and cause infectious diseases in consumers. in this study, available fruit juices in ilam shopping centres were investigated in 1389 to identify the presence of escherichia coli and the coliform number, aerobic bacteria, staphylococcus aurous, mo...

Background and Objectives: Nosocomial infections are one of the most important worldwide health and increased patients hospital stay, therapeutic problem and mortality rate. This study was designed to determine the frequency of microorganisms isolated from tracheal tube in patients admitted to ICU Shaheed Mostafa Khomeini Hospital Tehran, Iran, from 2001-2005. Patients and Methods: In this cros...

A series of interesting sulfonamides containing hydroxyl group were synthesized under solvent-free conditions. The synthetic route involves the selective reaction of amino alcohol and sulfonating agents. The sulfonamides were obtained by simple procedure after an easy work-up in high yield and purity, and characterized by IR, 1H NMR and 13C NMR analysis. These compounds were tested for antibact...

Objectives: Dental impressions are among the potentially infectious items in dentistry. Dental impressions are invariably contaminated with saliva or blood. Such fluids may contain viral or bacterial pathogens including Bacteroides, Fusobacterium, Porphyromonas and Prevotella. The aim of this study was to assess the effects of three different types of disinfectants on alginate impression materi...

Infection control was examined for 8 examples in which MRSA (Methycilin-Resistant Staphylococcus Aurous) from squint was detected in a neurosurgical ward. The stamp method was utilized for this MRSA infection research and analysis. Samples were gathered from a ward, patient environment and medical stafL uniforms. After those samples were collected, they were cultivated and identified. In additi...

The potential ability of a new yeast strain, Pichia kudriavzevii, in the synthesis of zinc oxide nanoparticles (ZnO-NPs) through a green method was explored in this study. The effect of reaction time (12, 24 and 36 h) on the structure of the resulting ZnO nanoparticles was investigated. From the XRD and TEM results, the ZnO-NPs with a hexagonal wurtzite structure and a particle crystal size of ...

Crude extracts from olive leaves and arugula seeds were screened for its in vitro antibacterial activity. Antibacterial activity was determined by using disc diffusion method against three bacteria (, Staphylococcus aurous and Bacillus cereus). Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) have been determined. Gallic acid was used as a standard drug for th...

The primary objective of this study was to determine the aetiology of bovine mastitis in ten herds of Holstein Friesian cow in Jordan, the prevalence of mastitis pathogens in dairy cows and their resistance to selected antimicrobial agents. Milk samples were collected from 220 lactating cows to determine the clinical and subclinical mastitis by white side test and confirmed by cultural tests. I...
