Background: Campylobacter jejuni is an important pathogen in developing diarrhea, unfortunately it was not mostly searched in ordinary diagnostic laboratories using selective C. jejuni medium and many diarrhea due to this bacterium remained undiagnosed. The aim of this study was to evaluate frequency of C. jejuni in stool samples of patients with bloody diarrhea.
Materials and methods: This is a descriptive cross-sectional study, in which frequency of C. jejuni was evaluated among 90 patients with diarrhea attending to Azad University hospitals between 2007 and 2008. Stool samples were cultured in skirrow`s medium and incubated in 42ْ C for 24-48 hours and bacterial colonies were assessed biochemically.
Results: Ninety patients with mean age of 13.08 years (range 4-80 years) were studied. 24 (26.7%) were male and 66 (73.3%) female (p<0.05). Of 90 patients, in 7 cases (7.8%) C. jejuni was obtained. Severe abdominal pain in C. jejuni positive cases was higher then C. jejuni negative subjects (28.6% in C. jejuni positive patients versus 7.2% of C. jejuni negative cases, p<0.05).
Conclusion: Because of importance of C. jejuni in bloody diarrhea and bacillary dysenteries, it is recommended the use of campylobacter selective medium such as skirrow`s or campybap in examination of diarrheic stools. |
