background and aims:nosocomial infections cause considerable morbidity and mortality and pose high financial burden on healthcare systems. although surface contact, surgical incisions, wounds and catheters are responsible for a high percentage of nosocomial infections, bacterial and fungal air contaminations in hospitals have an important role in development of hospital infections. the purpose ...
conclusions the world health organization (who) has suggested relatively relaxed limits of 100 cfu/m3 for bacteria and 50 cfu/m3 for fungi in the hospital air. therefore, quantitative and qualitative outcomes of this study demonstrate that contamination level and bacterial variety in surgery rooms and emergency departments is high and effective measures must be taken to control the possible hea...
background: bio-aerosols in the air of hospital wards have an important role in the development of infections. it is important to make quantitative and qualitative estimations of microorganisms in the air of these wards as an index for environmental hygiene applicable to different hospital wards. the aim of the study was to investigate degrees of diversity and density of bio-aerosols in the edu...
background some human diseases such as tuberculosis, legionnaires' disease and different forms of bacterial pneumonia, coccidioidomycosis, influenza, measles, and gastrointestinal illnesses are the result of exposure to bioaerosols. in addition, they are associated with some noninfectious airway diseases, such as allergies and asthma. objectives in the education hospitals of hamedan university ...
background and objective: bioaerosols are particles of microbes, viruses and derivatives; they exist in a wide variety of shapes and sizes and can be measured with different air samplers. the purpose of this study is the determination of bacterial aerosol in the air of hospitals and the determination of contaminated areas for disinfection proceedings by hospital health care teams, by selecting ...

Although surface contact, surgical incisions, wounds and catheters are responsible for a high percentage of nosocomial infections, bacterial and fungal air contaminations in hospitals have an important role in development of hospital infections. The p...
a novel chemical detergent/disinfectant formulated based on persulfate salts, germicide p , is available for disinfection of surfaces and medical devices at the room temperature. because of the resistance of hospital-resident microorganisms, the antimicrobial activity of this compound is evaluated in the present study. the tests conducted with this disinfectant included bactericidal tests again...
background and objective: implementation of standard methods for accurate detection of bacteria, correct antibiotic susceptibility testing and effective treatment of bacterial infections play important roles in development of public health and prevention of drug resistance. this study aimed to detect bacteria using standard methods and compare the results with the results obtained in teaching h...
background and objectives: hospital surfaces can serve as reservoirs of potential pathogenic bacteria.staff hands are the main source of bacterial transmission in hospital. the prevalence of bacteria harboring β– lactamase enzyme in staff hands and hospital surfaces, leads to spread of β–lactamase producing bacteria and ultimate increase of antibiotic resistance nosocomial infections. the aim o...
Antimicrobial activity of tigecycline against nosocomial pathogens in Pakistan: a multicenter study.
OBJECTIVE To measure the in-vitro activity of various antibiotics including tigecycline against Gram negative and positive nosocomial aerobic isolates. METHODS A total of 430 clinical isolates of both Gram positive (143) and negative (287) aerobic bacteria were used from 3 centres during the year 2006 and 2007. Minimum inhibitory concentration (MIC) was determined using broth micro dilution p...
