Question

A microbial agent that can survive processing by water treatment plant is: a. Cryptosporidium parvum b. Vibrio cholerae c. E. coli d. Tetanus e. Dracunculus medinensis

Answer 1

Answer:

a. Cryptosporidium parvum

Explanation:

Cryptosporidium is a protist parasite that has a spore phase. These spores are called oocysts. In this state the parasite can survive for long periods outside the host and can also resist many common disinfectants. Especially chlorine-based disinfectants. Due to this resistance, water treatment to remove Cryptosporidium in general is based on coagulation followed by filtration or boiling.
