Tick-borne pathogens in Thailand can cause diseases that result in productivity and
economic losses in the livestock sector as well as cause debilitating illnesses in humans and
their companion animals. With the advent of molecular techniques, accurate identification of
tick-borne pathogens and precise diagnosis of disease is now available. This literature review
summarizes the various tick-borne pathogens that have been isolated from ticks and their
vertebrate hosts in Thailand, covering those protozoa, rickettsiae, bacteria and viruses most
responsible for human and veterinary disease with particular emphasis on those that have
been characterized molecularly.
