A laboratory received a sample of water used in drug production for sanitary and viral analysis. What group of viruses will indicate fecal contamination of water and thus the need for its additional purification?
Correct answer
A
Rationale
The correct answer is A: Picornaviridae. Picornaviruses, such as enteroviruses, are commonly found in the feces of infected individuals. Therefore, their presence in water indicates fecal contamination and the need for additional purification.
B: Herpesviridae are not typically associated with fecal contamination.
C: Flaviviridae are mainly transmitted through arthropods like mosquitoes, not fecal contamination.
D: Retroviridae, including HIV, are not typically excreted in high levels in feces and are not indicators of fecal contamination.
