objective to investigate association between nosocomial infection, blood products transfusion and microorganisms responsible in patients who hospitalized at icu (intensive care unit). patients and methods in this prospective study, 217 patients who were admitted to the icu of taleghani hospital between august 2010 and august 2011 were included. nosocomial infections were defined using the conta...

results out of 2229 suspected meningitis cases, 255 (11.4%) were detected as positive culture. most of the isolates were gram-positive cocci, which 116 (45.5%) were staphylococcus epidermidis, and 20 (7.8%) identified as streptococcus spp. among gram-negative isolates, escherichia coli and acinetobacter spp., each with 19 isolates (5.9%), were predominant. overall, the most effective antibiotic...

background: methicillin-resistant (mrsa) staphylococcus aureus ( s. aureus ) are responsible for a vast number of nosocomial infections especially in immunocompromised subjects such as cancer patients. the presence of comorbidities including malignancies has been associated, with s. aureus bacteremia mortality. thus, the detection of mrsa in this patients and the antibiotic susceptibility patte...

the emergence of multidrug resistant strains of escherichia coli has complicated treatment decision and may lead to treatment failures. from april to november 2001 we prospectively evaluated the prevalence of resistance to trimethoprim-sulfamethoxazole (sxt), gentamicin, cephalothin, ciprofloxacin, and nitrofurantoin in 220 escherichia coli isolates from patients with urinary tract infections i...

results significant differences were observed in the results of co-culture of nematodes larva and fungi after seven days. the most effective fungi against the nematodes larvae were cladosporium sp., trichoderma sp., fusarium equisetti, after seven days of incubation. materials and methods sheep feces were employed to provide the required third stage larvae source for the experiments. the nemato...

background multiple sclerosis (ms) is a demyelinating condition affecting the central nervous system. although the cause of this condition is unknown, patients with ms seem to have genetic vulnerability to certain environmental factors such as infection that could trigger this condition. objectives we conducted this study to determine whether ms risk increases following primary infection with e...

results: in total, 8.5% of all subjects were positive (11% of symptomatic and 6% of asymptomatic men). statistical analysis revealed an association between condom usage as a variable and infection in asymptomatic group (p ≤ 0.05). conclusions: findings of this study show that chlamydial infection screening especially in males with urogenital symptoms is necessary (at least in tehran) and we rec...

conclusions mp, flub and rsv are the principal contributors to ari in the hubei area, with mixed infections, typically of mp and flub, being the most common pathogens statistically significant between different age groups. background acute respiratory infection (ari) is one of the primary diseases that cause high morbidity and mortality to children especially in developing countries. ari can co...

background: the role of the hospital environment as a source of dissemination of pathogens is critical. environmental surfaces in the intensive care units (icus) are suitable for the growth of gram-negative bacteria that normally circulate between the environment and patients and can cause outbreaks of nosocomial infections. in this study, the prevalence of gram-negative bacilli in the environm...

background: the risk for transmission of blood-borne viruses (bbvs) such as human immunodeficiency virus (hiv), hepatitis b virus (hbv) and hepatitis c virus (hcv) due to occupational exposure is a major concern in the health care setting. m aterials and methods: this study among 337 health care workers (hcws) accidentally exposed to bbvs was carried out from january 2009 to march 2015. the dat...
