Question

4
phage typing is useful in identifying ______.
multiple choice
salmonella
treponema pallidum
clostridium
mycobacterium leprae
streptococcus

Explanation:

Phage typing is a method used to identify bacterial strains, especially Salmonella. Among the options, Salmonella is commonly identified via phage typing. Treponema pallidum (causes syphilis, identified by other methods), Clostridium (identified by culture/biochemical tests), Mycobacterium leprae (leprosy, identified by microscopy/culture), and Streptococcus (identified by Gram - staining/culture) are less associated with phage typing for identification compared to Salmonella.

Answer:

The correct option is the one with "Salmonella" (the first option with the blue - filled circle).
