Question

question 13 (1 point)
which of the following statements about biological transmission is false?
the pathogen may require the vector as a host
the pathogen may be injected by the bite of the vector
the pathogen reproduces in the vector
houseflies are an important vector
the pathogen may enter the host in the vectors feces

Explanation:

Biological transmission involves a pathogen requiring the vector as a host (e.g., for development or reproduction), being injected by the vector's bite (like in mosquito - borne diseases), reproducing in the vector (as in some protozoan - vector relationships), and the pathogen can enter the host via vector feces (e.g., in some rickettsial infections). Houseflies are mainly mechanical vectors (they carry pathogens on their body parts without the pathogen undergoing development or reproduction in them), not important biological vectors.

Answer:

Houseflies are an important vector.
