The topic of tick-borne disease is complex, and presentation of information pertaining to it requires the use of technical terms. These terms are depicted in bold type and are explained in a glossary. Ticks are vectors of a wide range of disease agents worldwide, including viruses, bacteria, and protozoa. In North America, the role of ticks as vectors of two bacterial diseases, Lyme disease and Rocky Mountain spotted fever, is well documented. More recently, ticks have been implicated as vectors of additional diseases in North America, including anaplasmosis, babesiosis, and ehrlichiosis.
Ticks also are involved in tick paralysis, a condition caused by a toxin or toxins in the saliva of ticks. Every tick-borne disease is a zoonosis. There currently are no vaccines against disease agents transmitted by ticks available to the public, but early antibiotic therapy is effective against the disease agents transmitted in Indiana.

Bugs of Vietnam. This extraordinary creature was wandering around at night in the trees at Cat Tien. I thought it was a firefly larva, but it's actually the female of a net-winged beetle in the genus Duliticola. They're sometimes called "trilobite larvae" because the plates on their back make them resemble the much larger trilobites found as fossils. You can see a similarly weird but non-glowing Duliticola net-winged beetle larva in Malaysia. Like fireflies they have light emitting organs under the tail - the comma shaped bright area which is clearly visible even in this photo taken using flash. Unlike fireflies, the light which is emitted is constant rather than flashing, and it was this peculiar light which I first noticed, moving in a most unfirefly-like way, because this critter was walking on the trees rather than flying. Maybe I should say that it was dragging itself, because all six of its legs are at the front, and it only has bristle-tipped stumps along the rest of its body.
