the antimicrobial activity of thirty six novel dihydropyrimidine derivatives was evaluated against common pathogenic bacteria. significant antimicrobial activity (mic=32, 64 µg/ml) was observed. escherichia coli and pseudomonas aeruginosa as gram-negative bacteria and staphylococcus aureus as gram-positive bacteria were determined to be the most susceptible pathogens in this study. the highest ...

The study was undertaken to determine bacterial contamination of warm-water fish ponds and silver carps harvested from those ponds in Guilan province, Iran. In this respect, water samples were taken from 7 ponds and investigated by testing total bacteria, coliforms, and Escherichia coli. In addition, skin swab samples of silver carps caught from each pond were studied for enumeration of the sam...

Streptococcal bacteria are among dangerous human pathogens with major prevalence worldwide. A good vaccine against streptococcal bacteria should have epitopes that confer protection from infection by different streptococcal bacteria types. we aimed was to recognize the most immunogenic and conserved epitopes of streptococcal bacteria, which could be a potential candidate for vaccine development...

That some strains of the coliform group of bacteria exert inhibitory effects on other microorganisms, when grown in association in liquid media, was reported first by Nissle in 1916. Because of the multiplicity of factors involved when organisms are growing in heterogeneous mixtures in liquid media, the nature of the inhibiting agent is difficult to ascertain. Gratia of Belgium (1925) observed ...

Background and Objectives: This study was designed as a retrospective study on urine samples during three years in Shaheed Mostafa Khomeini Hospital to determine demographic characteristics of patients with urinary tract infection (UTI), microbial etiology, and susceptibility of isolated bacteria to anti...

Mobile phones and stethoscopes used in neonatology units could be colonized by potentiel bacteria pathogens. It can be a vector of severe nosocomial infections and multi-drug-resistant pathogens. The aim of this study is to evaluate the microbial contamination of mobile phones and stethoscopes, used by medical and paramedical staff. The study was conducted in neonatal intensive care unit (NICU)...

Backgrounds: Neutropenia can be associated with life-threatening infections. Gram negative and staphylococcal infections are the most common pathogens. The spectrum of bacterial isolates has changed considerably over the past four decades. The objective of the present study was to evaluate the pattern of bacterial and fungal infections in neutropenic pediatric patients. Methods: A non-randomize...
