Lake Manzala in Egypt have shown great changes in water properties including pH (7.4 to 8.4), total suspended solids (19 to 350 mg/l), total dissolved salts (1578 to 33480 mg/l), dissolved oxygen (2.25 to 8.45 mg/l), ammonia (0.00 to 44.8 mg/l) and nitrate (0.00 to 8.96 mg/l). In addition there has been quite high bacterial density in water and fish of the lake, including total viable bacterial counts and indicator organisms such as total coliforms, faecal coliforms and some other organisms

Our results herein showed that Lake Manzala is highly contaminated. Statistical analysis Correlation analysis (Fowler and Cohen 1996) was used to test the significance of relationships between the bacterial count and water characteristics of Bacterial pollution in lake manzala Arab Univ. J. Agric. Sci., 14(1), 2006 107 Lake Manzala. The correlation coefficient (r) and the probability (P) were used. RESULTS Physical and chemical parameters of Lake Manzala Water
