introduction: nosocomial infections (ni) are a frequent and relevant problem, in other hands; those are responsible of mortality especially in pediatric icu( intensive care unit) and nicus (neonatal intensive care unit). healthcare-associated infections are important in wide-ranging concern in the medical field. the most cause of nosocomial infection include: bloodstream infection, urinary trac...

background nosocomial infections are generally occurring 72 hours after admittance and are not present or incubating prior to admittance. the most common nosocomial infection is urinary tract infection (uti). scanty data are available regarding the nosocomial infections in iranian teaching hospitals. the aim of the present study was to determine the frequency of symptomatic nosocomial uti, iden...

background: tourniquets used repeatedly on patients for blood sampling are a potential source of nosocomial infections. they harbor numerous microorganisms, including methicillin‑resistant staphylococcus aureus (mrsa). the aim of this study was to investigate tourniquets for the presence of microorganisms and to ascertain the infection control practices of health care workers. methods: a cross‑...

background: nosocomial rhino sinusitis causes major problems in all intensive care units (icus). objective: to describe incidence, epidemiologic, clinical manifestations, and microbiologic findings in icus admitted cases with nosocomial sinusitis. materials and methods: a prospective, cross sectional study done in pediatric & adult icus in rasoul akram hospital; tehran iran (2007-2008). para-na...

background: bacillus subtilis refers to stretched and sometimes curved, gram-positive, aerobic, and catalase-positive bacilli, which has thermo-resistant endospores. it has been known as a normal flora in the human but can be pathogens in the case of opportunistic. also, it can be the pathogen of nosocomial infections such as wound among hospitalized patients. purpose of this study was to ident...

introduction liver abscess developing during hospital stay in pediatric patients on dialysis for acute kidney injury has been previously unreported. impaired immunity, prolonged use of antibiotics, diabetes and malnutrition predispose to liver abscess in chronic hemodialysis patients. case presentation we reported a case of liver abscess developing in a 6-year-old boy admitted with sepsis and m...

conclusions isaba1 has become an important factor in a. baumannii’s resistance to cefotaxime. results isaba1 located upstream of blaampc was found in 24 (48%) of the a. baumannii isolates. in all of the studied isolates that had isampc, the mic for cefotaxime was 64 - 256 μg/ml. based on the rep-pcr patterns among the resistant isolates, the highest number of isampc positive isolates belonged t...

coagulase-negative staphylococci (cns) are a main cause of nosocomial infection. the main purpose of this study was to determination of frequency of cns isolates in in hospitalized patients and their susceptibility pattern to antimicrobial agents. during 11 month study, 65 cns clinical isolates were recovered from hospitalized patients in different wards of hospital. in vitro susceptibility of ...

results the present study indicates that carbapenems and new cephalosporin antibiotics were practically ineffective against the extensive drug resistance (xdr) strains. colistin was observed to be more effective, although in seven cases resistance to colistin observed. ampc β-lactamase and mbl could be an important contributory factor for imipenem resistance among the isolates in our hospital. ...
