Colonization of Pathogenic Microbes on Contaminated Nebulizer Devices for Respiratory Tract Diseases at Emergency Department in Hospitals

Abstract

Poor nebulizer hygiene can result in microbial contamination and risk of infections by pathogens for respiratory tract patients. Swabs were collected from contamination nebulizer cup (n=25) using sterile cotton swabs, percentage of microbial contamination 84( 67.2%) bacteria n=74(59.2%) [gram positive n=21(16.8%), and negative bacteria n=53(42.4%)]. and yeast n=10(8%) (Candida spp.). Frequency of gram negative bacteria higher than the gram positive bacteria and yeast with high significant difference p≤0.05. In this study concluded that the nebulizer devices are contaminated with microbial pathogens and the transmission of these microbes among the respiratory tract patients and this is due to the disinfection of these devices or did not disinfected well to reduce these microbes.
