Answer :
Final answer:
The two major groups of diseases transmitted by mites are scrub typhus and rickettsial pox.
Explanation:
Mites act as vectors for these diseases. Scrub typhus, caused by the bacterium Orientia tsutsugamushi, is transmitted by chigger mites. It is characterized by fever, headache, body aches, and sometimes a rash. Rickettsial pox, caused by Rickettsia akari, is transmitted by mouse mites and presents with symptoms similar to those of chickenpox, including a vesicular rash.
The transmission of these diseases is an example of biological transmission, involving the survival and reproduction of pathogens within a parasitized vector. This complicate the biology of the pathogen and its mode of transmission, representing a significant challenge in managing and controlling the spread of diseases caused by mites.
