Abstract

Water could be a crucial transmitter of nosocomial infections in patients who are admitted to hospitals’ Intensive Care Unit (ICU). The present study was undertaken to evaluate the microbiological quality of different water samples from ICU of tertiary care hospitals for measuring their potential of causing nosocomial infections. In this regard, drinking and tap water samples were collected from the ICU of three tertiary care hospitals located in Dhaka, Bangladesh. Total viable bacteria were present in an average of 3 log₁₀ cfu/ml in all the samples. Among the specific bacterial isolates, Pseudomonas spp. and Bacillus spp. were predominant and encountered in all samples. E. coli contamination was observed in almost all water samples collected of the three ICUs. Staphylococcus spp. and Klebsiella spp. were recovered in water samples from ICU-1 and ICU-2. Fecal coliforms and Vibrio spp. were alarmingly found in the tap water samples of ICU-1. A few of the isolates from the water samples of ICUs were able to form biofilm on the Congo red media that accelerate the risk. Moreover, the bacterial isolates were found to be multidrug resistant. Higher resistance was found against Cefixime, Amoxicillin, Nalidixic Acid, Cephradine and Piperacillin. Overall, The findings of the present study reveal that the tested ICU water samples could be a potential source of nosocomial infections by the drug-resistant bacteria.
