STUDY OF THE MICROBIOLOGICAL CONTAMINATION OF THE AIR FROM A FAMILY MEDICAL OFFICE

Indoor air of a family medical office was analyzed in order to investigate the level of the microbial contamination, because a series of diseases and infections can be transmitted to patients through the air. The determinations were made from October 2018 until May 2019, considering the consulting room, the treatment room, respectively the waiting room. For the enumeration of the total germs number and the streptococcal and fungal populations of the air, the Koch sedimentation technique was used. The microbiological contamination of the air within this study shows the surpassof the suggested standard for the air bacterial load from a medical building. The results highlight a high degree of air pollution in the medical unit, especially in the winter months, when the traffic is more intense and the ventilation is deficient. The aeromicroflora in the treatment room has the highest number of germs, respectively hemolytic streptococci and fungi. The microorganisms isolated in this study from the microscopic examination includes: Penicillium sp., Bacillus sp., Streptococcus sp., Tetrads. Thus, it is necessary to permanently monitor the quality of the air inside the medical office, by applying appropriate cleaning and disinfection methods and by the control of the environmental factors that favor the growth and propagation of microbes.
