The results showed that 20% of Salmonella typhi bacteria were found, 7% of other bacteria and 73% of bacteria did not grow on the media. The macroscopic characteristics of salmonella bacteria found were round colonies, clear in color, convex surface, flat colony edges, semi mucoid consistency, no reduction of tellurit. The microscopic characteristics are rod-shaped, spread arrangement, red in color and are Gram negative.
