background: this study was done to detect multidrug resistant (mdr) and extremely drug resistant (xdr) of pseudomonas aeruginosa among strains isolated from patients in tehran, iran, due to importance of these phenotypes in treatment of human infections. methods: eighty eightp. aeruginosa were isolated from patients in tehran, iran, and identified by routine methods and pcr for oprl gene. their...

PURPOSE The goal of this study was to characterize the patterns of antimicrobial resistance and virulence genes in samples of Staphylococcus aureus (S. aureus) isolated from periodontitis patients. METHODS From July 2015 to August 2015, oral saliva was collected from a total of 112 patients diagnosed with periodontitis, including 80 outpatients in dental hospitals and 32 patients in dental cl...

backgrounds: different susceptibility rates of pathogenic bacteria to antimicrobial agents are considered major factors in the choice of drugs and the success of treatments. concerns have been raised regarding the emergence of antimicrobial resistance among pathogenic bacteria that may result in unpredictable antimicrobial susceptibilities and therapy failure. objectives: the purpose of this in...

OBJECTIVE To determine the antimicrobial susceptibility, phage type and plasmid profile pattern of Salmonella enterica serotype paratyphi A strains isolated in Kuwait. MATERIAL AND METHODS From January 1995 to December 1999, 106 strains of S. enterica serotype paratyphi A isolated from an equal number of cases of enteric fever, attending the Infectious Disease and Mubarak Al-Kabeer Hospitals ...

BACKGROUND AND PURPOSE Diarrheal diseases are an important cause of morbidity and mortality in children in developing countries. Of the bacterial causes of dysentery, Shigella are the major enteropathogens with outbreak potential and common development of antimicrobial resistance. This study determined the prevalence and antimicrobial susceptibility patterns of different spp. of Shigella in Asm...

Bacterial pathogens are becoming more and more resistant to antibiotics used commonly by healthcare practitioners. Despite introduction of new antibiotics, empiric treatment of patients with bloodstream infections (BSIs) became a major challenge for practicing physicians.1,2 To depict the susceptibility patterns of BSI pathogens endemic in a referral pediatric hospital, Children’s Medical Cente...

INTRODUCTION Bloodstream infections are associated with significant patient morbidity and mortality. Antimicrobial susceptibility patterns should guide the choice of empiric antimicrobial regimens for patients with bacteremia. METHODS Blood sample received from the patient attending Nepal Medical College and Teaching Hospital from March, 2012 - August, 2012 were subjected to culture. Isolate ...

An increase in the occurrence of potentially pathogenic Vibrio species is expected for waters in Northern Europe as a consequence of global warming. In this context, a higher incidence of Vibrio infections is predicted for the future and forecasts suggest that people visiting and living at the Baltic Sea are at particular risk. This study aimed to investigate antimicrobial resistance patterns a...

BACKGROUNDS: Different susceptibility rates of pathogenic bacteria to antimicrobial agents are considered major factors in the choice of drugs and the success of treatments. Concerns have been raised regarding the emergence of antimicrobial resistance among pathogenic bacteria that may result in unpredictable antimicrobial susceptibilities and therapy failure. OBJECTIVES: The purpose of this in...

Salmonellosis is a very important disease of avian species because of its huge economic impact, worldwide distribution and difficulty posed in its control. Fowl typhoid and pullorum disease, is caused by Salmonella enterica subsp enterica serovar Gallinarum biovar Gallinarum and Pullorum. The purpose of this study was to investigate the biochemical characteristics and antimicrobial susceptibili...
