List selective media for stool culture?
MacConkey agar: Selective for Gram-negative bacteria, inhibits the growth of Gram-positive bacteria. Hektoen enteric agar: Selective for Gram-negative enteric pathogens, such as Salmonella and Shigella species. Thiosulfate-citrate-bile salts-sucrose (TCBS) agar: Selective for Vibrio species, especially Vibrio cholerae. Cefsulodin-irgasan-novobiocin (CIN) agar: Selective for Yersinia species.
What is Salmonella shigella yersinia and serratia?

Biochemical test used in identification of salmonella typhi?
The biochemical test commonly used to identify Salmonella typhi is the Widal test. This test detects antibodies produced in response to a Salmonella typhi infection by measuring agglutination (clumping) reactions between the bacteria and specific antibodies in the patient's serum. Other tests like blood culture and polymerase chain reaction (PCR) can also be used for confirmation.
How does salmonella appear in agar?
Salmonella appears as colorless to slightly transparent colonies on agar plates like MacConkey agar or XLD agar. These colonies often have a pink or red center surrounded by a white or transparent outer edge. Additional biochemical tests are typically needed to confirm the presence of Salmonella species.
Biochemical tests for Salmonella and Shigella?
urease - negative ONPG - positive Lysine - positive
What are some names of bad microbes?
