increases in body mass index (bmi) are reported to influence asthma response to treatment. the aim of this study was to investigate the relationship between bmi and response to treatment in a group of patients that were referred for asthma control. effectiveness measurements in this analysis included percentage of changes in forced volume in 1 second (fev1), forced volume capacity (fvc), fev1/f...

conclusions our results showed the rate of effects of different risk factors on imipenem resistance. regarding the studied risk factors, appropriate programs must be set in place to control and prevent imipenem resistance in gram-negative bacteria. results of the 374 isolated, 134 were imipenem resistant, and 240 were sensitive to imipenem. the resistance rate was more common in males and in pa...

background metallo-beta-lactamase (mbl) producing pseudomonas aeruginosa in the burn patients is a leading cause of morbidity and mortality and remains a serious health concern among the clinicians. objectives the aim of this study was to detect mbl-producing p. aeruginosa in burn patients and determine multidrug-resistant (mdr) strains, and respective resistance patterns. patients and methods ...

Drug resistance (especially multiple drug resistance) in Mycobacterium tuberculosis makes global concerns in treatment and control of tuberculosis. Rapid diagnosis of drug resistant strains of the bacteria has vital importance in the prognosis of the disease. The aim of this study was to identify the mutations responsible for drug resistance in Mycobacterium tuberculosis strains derived from pa...

background: listeria monocytogenes is one of the most important food-borne bacteria causing septicemia, meningitis and encephalitis in humans. the objective of this study was to evaluate the occurrence and antibiotic resistance of the bacterium in retail minced beef in ahvaz, south-west of iran. methods: in this survey, 150 samples of minced beef were randomly obtained from retail butcheries in...

abstract       background and objective: enterococci are relatively nonvirulent bacteria that rarely cause disease. antimicrobial treatment of enterococci is often challenging due to their antibiotic resistance. this study aimed to investigate the antibacterial activity of aqueous extract of garlic against enterococcal isolates.     methods: in this descriptive study, 120 enterococcus isolates ...

this study was planned to determine hiv seroprevalence among pulmonary tuberculosis patients, to characterize the isolated mycobacteria into typical and atypical strains and to evaluate the drug resistant pattern of mycobacterial isolates. the study aims to correlate multidrug resistance (mdr) and hiv seropositivity status in pulmonary tuberculosis patients. during the year 1994-1997, 750 pulmo...
