Abstract

Background and Aim: Nosocomial Infections have always been one of the major health problems, and it is becoming increasingly important and a challenge to the health system of different countries. In this study, the contamination was studied in the environment and medical equipment in two teaching hospitals of Mashhad University of Medical Sciences. Materials and Methods: This cross-sectional study was performed in two teaching hospitals. A convenience sampling method was used based on the policies of the infection control committee of each hospital. Environmental samples were collected from sink, patient bed, and incubators. Samples were cultured in bacterial culture media and phenotypically identified. Results: Out of 323 samples, 272 (84. 2%) were from Qaem Hospital and 51 (15. 8%) from Imam Reza Hospital. Overall, 47. 1% of samples from Ghaem hospital (128 samples) and 33. 3% of samples from Imam Reza hospital (17 samples) were positive (p = 0. 071). Overall, the most prevalent organisms were Bacillus (54 samples, 16. 7%), followed by Staphylococcus epidermidis (22 samples, 6. 8%), and Staphylococcus saprophyticus (16 samples, 0. 5%). Others consisted of Acinetobacter, Enterobacter, and Pseudomonas spp. Conclusion: Bacillus species have high persistence in the environment due to sporulationand their removal will be an indicator of proper environmental health. The presence of potentially pathogenic bacteria in the hospital environment reveals the importance of environmental health control and monitoring programs.
