Ixodes siamensis is an ixodid tick (hard tick) that is parasitic on mammals in Thailand. [1] [2]
Ticks are parasitic arachnids that are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, species, and "fullness". 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.
Maclear's rat is an extinct large rat endemic to Christmas Island in the Indian Ocean. It was one of two species of rat native to Christmas Island, alongside the bulldog rat. Abundant, unfamiliar with and seemingly unafraid of humans, large numbers of the creatures emerged and foraged in all directions at night. Making querulous squeaks, the rats entered the Challenger Expedition's tents and shelters in 1886, ran over sleepers, and upset everything in the search and fight for food. Maclear's rat might have been responsible for keeping the population of the Christmas Island red crab in check, as recent numbers of the crab are greater than in the past. It is thought that black rats inadvertently introduced by the expedition infected the Maclear's rats with a disease, which in turn could have contributed to the species' decline. The last recorded sighting was in 1903, although it is possible that Maclear's rats hybridized with black rats. A hard tick, described as an ectoparasite of Maclear's rat, is also thought to be extinct.
"Candidatus Midichloria" is a candidatus genus of Gram-negative, non-endospore-forming bacteria, with a bacillus shape around 0.45 µm in diameter and 1.2 µm in length. First described in 2004 with the temporary name IricES1, "Candidatus Midichloria" species are symbionts of several species of hard ticks. They live in the cells of the ovary of the females of this tick species. These bacteria have been observed in the mitochondria of the host cells, a trait that has never been described in any other symbiont of animals.
Powassan virus (POWV) is a Flavivirus transmitted by ticks, found in North America and in the Russian Far East. It is named after the town of Powassan, Ontario, where it was identified in a young boy who eventually died from it. It can cause encephalitis, an infection of the brain. No approved vaccine or antiviral drug exists. Prevention of tick bites is the best precaution.
Ixodes is a genus of hard-bodied ticks. It includes important disease vectors of animals and humans, and some species inject toxins that can cause paralysis. Some ticks in this genus may transmit the pathogenic bacterium Borrelia burgdorferi responsible for causing Lyme disease. Additional organisms that may be transmitted by Ixodes are parasites from the genus Babesia, which cause babesiosis, and bacteria from the related genus Anaplasma, which cause anaplasmosis.
Ixodes scapularis is commonly known as the deer tick or black-legged tick, and in some parts of the US as the bear tick. It was also named Ixodes dammini until it was shown to be the same species in 1993. It is a hard-bodied tick found in the eastern and northern Midwest of the United States as well as in southeastern Canada. It is a vector for several diseases of animals, including humans and is known as the deer tick owing to its habit of parasitizing the white-tailed deer. It is also known to parasitize mice, lizards, migratory birds, etc. especially while the tick is in the larval or nymphal stage.
Ixodes ricinus, the castor bean tick, is a chiefly European species of hard-bodied tick. It may reach a length of 11 mm (0.43 in) when engorged with a blood meal, and can transmit both bacterial and viral pathogens such as the causative agents of Lyme disease and tick-borne encephalitis.
Mus mayori is a species of rodent in the genus Mus, the mice. Its common names include Mayor's mouse, highland rat, and spiny mouse. It is endemic to Sri Lanka.
The northern white-breasted hedgehog is a species of hedgehog.
Rhipicephalus is a genus of ticks in the family Ixodidae, the hard ticks, consisting of about 74 or 75 species. Most are native to tropical Africa.
Ixodes pacificus, the western black-legged tick, is a species of parasitic tick found on the western coast of North America. I. pacificus is a member of the Ixodidae (hard-bodied) family. It is the principal vector of Lyme disease in that region. I. pacificus typically feeds on lizards and small mammals therefore its rate of transmission of Lyme disease to humans is around 1% of adults. It is an ectoparasite that attaches itself to the outside of its host and feeds on the host's blood. It can have a heteroxenous lifestyle or monoxenous life cycle depending on how many hosts it feeds on in each cycle. I. pacificus has a four stage life cycle that takes around 3 years to complete. These stages include egg, larva, nymph, and adult. They prefer dense woodland habitats or areas of brush and tall grass.
Ornithodoros is a genus in the soft-bodied tick family, Argasidae.
Ixodes uriae, also known as the seabird tick, is a species of parasitic tick known to infest marine birds. It is native to many high latitude areas in the northern and southern hemispheres including Alaska, Canada, Faroe Islands, Iceland, Greenland, England, Scotland, Norway, Finland, the Kola Peninsula, Russia, Patagonia, South Africa and Australia.
Ixodes hexagonus, also known by the common name hedgehog tick, is a tick species in the genus Ixodes. It is a parasite of the European hedgehog.
Alpha-gal allergy — or mammalian meat allergy (MMA) — is a type of meat allergy characterized by a delayed onset of symptoms after ingesting mammalian meat and resulting from past exposure to tick bites. It was first reported in 2002. Symptoms of the allergy include rash, hives, nausea or vomiting, difficulty breathing, drop in blood pressure, dizziness or faintness and severe stomach pain.
Amblyomma testudinarium is a hard-bodied tick of the genus Amblyomma. It is found in Indonesia, India, Japan, Thailand, Sri Lanka and Vietnam. Adults parasitize various larger mammals such as buffalo and cattle, whereas nymphs and larvae use mostly larger and medium mammals.
Ornithodoros sawaii is a species of argasid tick that is parasitic on streaked shearwater and Swinhoe's storm petrel seabirds in Japan and Korea. The species name honors Hirofumi Sawa of Hokkaido University in Sapporo, Japan.
Paul Schulze was "the most important German tick taxonomist of the early 20th century." Between 1929 and 1937, he described 19 genera, 17 subgenera, 150 species and 150 subspecies of ixodid ticks. He was essentially an amateur taxonomist, working alone for most of his career, not consulting the major tick collections or collaborating with other tick taxonomists.
Natalia Aleksandrovna Filippova was a world authority on the taxonomy of mites and especially ticks. Her monographs on the identification, morphology, development, distribution and behaviour of the family Argasidae and the sub-families of Ixodinae and Amblyomminae are standard works on these important vectors of disease.
Ixodes anatis, also called the kiwi tick, is a species of tick in the arthropod family Ixodidae. It is endemic to New Zealand and mainly parasitizes kiwi.
