A comparative study on detecting bacterial flora of the nasal cavity in normal healthy workers that work in cement factory and the healthy Students in Koya University

Abstract

In this study, a total of 45 samples were collected from the nasal cavity of biology healthy students that taking education in the 2012-2013 in Koya University, Faculty of Science and health, and 35 healthy workers that work in Mas cement factory were attending in this study. From this 45 healthy students seventeen (37.77%) of them had no growth isolated, sixteen of them (35.55%) were found out that they had Streptococcus spp. While nine (20%) students had Staphylococcus spp. two (4.44%) of the isolates were E. coli and two (4.44%) of the isolates overall these 45 students were Klebsiella spp. From 35 healthy workers were attending in this study, two (5.71%) of the workers were found that they had no growth isolated, while eighteen (51.42%) of the workers were found out that they had Moraxella catarrhalis, thirteen (37.14%) of the workers had Candida albicans, five of them (14.28%) had streptococcus faecalis, three (8.57%) of them had E.coli, two (5.71%) of them had Klebsiella spp., and one (2.85%) of the growth found Citrobacter freundii. The nasal Streptococcus spp. Isolates were found out significantly that were higher than other isolates. The nasal Moraxella catarrhalis Isolates were found out significantly higher than other isolates among the workers that have contact with cement.
