Ticks are The vector of bacteria that Causes relapsing fever
GENERAL CHARACTERISTICS OF BORRELIA DUOTTONI,
B. RECURRENTIS :- The tick’s form consists of a capitulum (head) and a flattened, oval-shaped body called the idiosoma. Like spiders and other arachnids, adult ticks and nymphs have eight legs, though larvae emerge from the egg with only six. Hard ticks, like the ones found in Maine, have a hardened plate on the dorsal surface called a scutum. On females, this scutum takes up approximately 1/3 of the dorsal surface and can be useful in differentiating tick species. On males, the scutum covers the entire dorsal surface and limits their feeding ability. The tick’s mouthparts are located on the capitulum and are made up of the chelicerae and hypostome, which are used to penetrate and secure the tick to its host. During feeding, ticks secrete substances that help anchor it to the host, act as an anesthetic to mask the pain from the bite, and prevent blood from coagulating. Since ticks are efficient feeders and tenacious once attached, there is potential for transmitting disease. Mainers should be in the habit of performing tick checks after frequenting tick habitat.
