Passive (mechanical) transmission Correct Ans-This method of transmission occurs when the
arthropod Carrie's the pathogen from one host to another; Pathogen "goes along for the ride"
Active (biological) transmission Correct Ans-In this method of transmission, the disease-
causing agent undergoes some change in the body of the arthropod; The pathogen may
multiply or simply develop into an infectious form
4 Ways Pathogens can be passed to humans (by active transmission) Correct Ans-
Inoculation, Regurgitation, Fecal contamination, Crushing the vector
Inoculation Correct Ans-A vector injects the pathogen into the host with its saliva while it
feeds on the host; Mosquitoes transmit malaria by this process
Regurgitation Correct Ans-The vector vomits the pathogen into the host while it feeds on the
host; Fleas transmit bubonic plague by this process
Fecal Contamination Correct Ans-The vector defecates into a wound on the host, which
starts itching, scratching, thus entering the host's body
Crushing the vector Correct Ans-The vector is smashed onto skin of host, pathogen rubbed
into the skin, body louse transmits epidemic typhus in this manner
Mosquitoes Correct Ans-Who are the most significant Artropods?
