A coliform bacterium that likely contaminates dairy products is ___________.
a. Bartonella
b. Serratia
c. Enterobacter
d. Proteus
Guida verificata passo dopo passo1
Understand that coliform bacteria are a group of Gram-negative, rod-shaped bacteria that ferment lactose with gas and acid production within 48 hours at 35-37°C. They are commonly used as indicators of sanitary quality of foods and water.
Recall that coliforms belong mainly to the family Enterobacteriaceae, which includes genera such as Escherichia, Enterobacter, Klebsiella, and Citrobacter.
Review the options given: Bartonella, Serratia, Enterobacter, and Proteus. Identify which of these are members of the Enterobacteriaceae family and are known coliforms.
Note that Enterobacter is a well-known coliform bacterium often associated with contamination in dairy products due to its ability to ferment lactose and survive in such environments.
Conclude that among the options, Enterobacter is the most likely coliform bacterium contaminating dairy products based on its classification and characteristics.

Coliform Bacteria
Coliform bacteria are a group of Gram-negative, rod-shaped bacteria commonly found in the environment, including soil and water, and are used as indicators of sanitary quality. They ferment lactose with gas production within 48 hours at 35-37°C, which helps identify potential contamination in food and water.
