Microbiological Air Contamination in Hospital

Predrag Ilić, Jelena Božić, Svetlana Ilić

Abstract


The aim of this study was to assess the microbiological contamination levels of indoor pollution in General hospital in Doboj-Department of Microbiology and Patoanatomy and Department of Microbiology with Parasitology of the Republic of Srpska (Bosnia and Herzegovina). Concentration of bacteria and fungi was determined in order to evaluate the microbiological quality of the air in the subject Hospital. Furthermore, correlation of airborne bacteria and fungi with environmental parameters (temperature, relative humidity) was investigated. Air samples were collected during the winter season (February, 2017) at nine different locations. Variation of microorganism in air samples was discussed, through experimental measuring. The paper presents the average values of bacteria and fungi (in CFU/m3). Maximum, minimum and other statistical values are in correlation with microclimatic parameters. Variations are directly connected to relative humidity. The results of this study show the high level of microbiological contamination of the air. Increased ventilation, alongside with HVAC system and other hygiene measures in the subject hospital would significantly contribute to the improvement microbiological quality of the indoor air.
