Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates.
Amblyomma americanum, also known as the lone star tick, the northeastern water tick, or the turkey tick, is a type of tick indigenous to much of the eastern United States and Mexico, that bites painlessly and commonly goes unnoticed, remaining attached to its host for as long as seven days until it is fully engorged with blood.
The ticks that transmit Lyme disease are hard ticks. [4] Ticks often have a preferred host, but may still attach to a different host when called for. Their preferred host may change depending on the tick's stage of development (eg larval vs adult) and the host may or may not carry the transmittable pathogen. [3]
Lyme disease, also known as Lyme borreliosis, is a tick-borne disease caused by species of Borrelia bacteria, transmitted by blood-feeding ticks in the genus Ixodes. [4] [9] [10] The most common sign of infection is an expanding red rash, known as erythema migrans (EM), which appears at the site of the tick bite about a week afterwards. [1]
As of 2020 18 tick-borne pathogens have been identified in the United States according to the Centers for Disease Control [10] and at least 27 are known globally. [8] [11] [12] New tick-borne diseases have been discovered in the 21st century, due in part to the use of molecular assays and next-generation sequencing. [13]
The origins of Tick, Tick... Boom! are quite fascinating, but is it based on a true story? Well, the movie is an adaptation of a stage musical of the same name, created by Jonathan Larson
Ixodes scapularis is commonly known as the deer tick or black-legged tick (although some people reserve the latter term for Ixodes pacificus, which is found on the west coast of the US), and in some parts of the US as the bear tick. [2] It was also named Ixodes dammini until it was shown to be the same species in 1993. [3]
