60 water samples were collected from 3 sources (Mahmoudia Canal, 20; Ground Water, 20; and Mariout Lake, 20) and examined for detection of Camoylobacter jejuni and faecai Coliform organisms using membrane filter technique and most probable number (MPM). The incidence of Campylobacter jejuni in Mahmoudia canal, ground water and Mariout lake were 13.3, 3.3; and 6.7% respectively. The most probable number of Campylobacter jejuni in Mahmoudia canal, ground water and Mariout lake were 49.1+3.4; 18.5+6.7 and 24.8+4.7 organisms/100 ml of water while for faecal Coliform were 1153.8+ 29.9, 816.5+589.9 and 185.0+417.1
organisms/ 100 ml of water.
Membrane filter technique was found to be efficient in the isolation of Campylobacter from different sources. Moreover, a positive correlation between Campylobacter jejuni and faecal Coliform bacteria (r= 0.53) was revealed,
