Leptotrombidium
''Leptotrombidium'' () is a genus of mites in the family Trombiculidae, that are able to infect humans with scrub typhus (''Orientia tsutsugamushi'' infection) through their bite. The larval form (called chiggers) feeds on rodents, but also occasionally humans and other large mammals. They are related to the harvest mites of the North America and Europe. Originally, rodents were thought to be the main reservoir for ''O. tsutsugamushi'' and the mites were merely vectors of infection: that is, the mites only transferred the contagion from the rodents to humans. However, the mites are now known to only feed once in their lifetimes, which means that transmission from rodent to human via the mites is impossible (for it to have been possible, the mite would have to feed at least twice, once on the infected rodent and again on the human who would then be infected). Instead, the bacterium persists in the mites through transovarial transmission Transovarial or transovarian trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orientia Tsutsugamushi
''Orientia tsutsugamushi'' (from Japanese ''tsutsuga'' meaning "illness", and ''mushi'' meaning "insect") is a mite-borne bacterium belonging to the family Rickettsiaceae and is responsible for a disease called scrub typhus in humans. It is a natural and an obligate intracellular parasite of mites belonging to the family Trombiculidae. With a genome of only 2.0–2.7 Mb, it has the most repeated DNA sequences among bacterial genomes sequenced so far. The disease, scrub typhus, occurs when infected mite larvae accidentally bite humans. Primarily indicated by undifferentiated febrile illnesses, the infection can be complicated and often fatal. ''Orientia tsutsugamushi'' infection was first reported in Japan by Hakuju Hashimoto in 1810, and to the Western world by Theobald Adrian Palm in 1878. Naosuke Hayashi first described it in 1920, giving the name ''Theileria tsutsugamushi''. Owing to its unique properties, it was renamed ''Orientia tsutsugamushi'' in 1995. Unlike other ...

Trombiculidae
Trombiculidae (); commonly referred to in North America as chiggers and in Britain as harvest mites, but also known as berry bugs, bush-mites, red bugs or scrub-itch mites, are a family of mites. Chiggers are often confused with Tunga penetrans, jiggers – a type of flea. Several species of Trombiculidae in their larva stage bite their animal or human host and by embedding their mouthparts into the skin cause "intense irritation" or "a wheal response, wheal, usually with severe itching and dermatitis". Trombiculidae live in forests and grasslands and are also found in the vegetation of low, damp areas such as woodlands, berry bushes, orchards, along lakes and streams, and even in drier places where vegetation is low, such as lawns, golf courses, and parks. They are most numerous in early summer when grass, weeds, and other vegetation are heaviest. In their larval stage, they attach to various animals, including humans, and feed on skin, often causing itching. These relatives of ...

Parasitic Arthropods Of Humans
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted paras ...

Northern Territory, Australia
The Northern Territory (commonly abbreviated as NT; formally the Northern Territory of Australia) is an Australian territory in the central and central northern regions of Australia. The Northern Territory shares its borders with Western Australia to the west (129th meridian east), South Australia to the south (26th parallel south), and Queensland to the east (138th meridian east). To the north, the territory looks out to the Timor Sea, the Arafura Sea and the Gulf of Carpentaria, including Western New Guinea and other islands of the Indonesian archipelago. The NT covers , making it the third-largest Australian federal division, and the 11th-largest country subdivision in the world. It is sparsely populated, with a population of only 249,000 – fewer than half as many people as in Tasmania. The largest population center is the capital city of Darwin. The archaeological history of the Northern Territory may have begun more than 60,000 years ago when humans first settled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Litchfield National Park
Litchfield National Park, covering approximately 1500 km2, is near the township of Batchelor, 100 km south-west of Darwin, in the Northern Territory of Australia. Each year the park attracts over 260,000 visitors. Proclaimed a national park in 1986, it is named after Frederick Henry Litchfield, a Territory pioneer, who explored areas of the Northern Territory from Escape Cliffs in Van Diemen Gulf to the Daly River in 1864. History Early history Aboriginal people have lived throughout the area for thousands of years. It is important to the Kungarakan and Marranunggu peoples for whom their ancestral spirits, still considered actively present in the landscape, played a seminal role in forming the landscape, plants and animals of this area. Recent history The park was named after Frederick Henry Litchfield, a member of the Finniss Expedition that travelled from South Australia in 1864. This was the first European expedition to visit the Top End of Australia by lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
