Holothyridae
The Holothyrida are a small order of mites in the superorder Parasitiformes. No fossils are known. With body lengths of more than they are relatively large mites, with a heavily sclerotized body. It is divided into three families, Allothyridae, Holothyridae, and Neothyridae. In a 1998 experimental study, members of the family Allothyridae were found to ignore living animals but readily fed on the body fluids of death arthropods. The order has a distribution largely confined to former Gondwanan landmasses. They are the sister group to Ixodida (ticks).Dobson & Barker 1999 Systematics Allothyridae Allothyridae van der Hammen, 1972 — Australia, New Zealand * '' Allothyrus'' van der Hammen, 1961 :* '' Allothyrus australasiae'' (Womersley, 1935) :* '' Allothyrus constrictus'' (Domrow, 1955) * '' Australothyrus'' van der Hammen, 1983 :* '' Australothyrus ocellatus'' van der Hammen, 1983 Holothyridae Holothyridae Thorell, 1882 Sri Lanka, Indian Ocean islands, New Guinea, New Ca ...

Parasitiformes
Parasitiformes are a superorder of Arachnids, constituting one of the two major groups of mites, alongside Acariformes. Parasitiformes has, at times, been classified at the rank of order or suborder. It is uncertain whether Parasitiformes and Acariformes are closely related, and in many analyses they are recovered more closely related to other arachnids. Amongst the best known members of the group are the ticks, though the Mesostigmata is by far the most diverse group with over 8,000 described species, including economically important species such as the varroa mite. Description Taxonomy * Holothyrida - small group of scavenging mites native to former Gondwana landmasses * Ixodida – ticks * Mesostigmata – a large order of predatory and parasitic mites * Opilioacarida – a small group of large, long-legged segmented mites. Many species are parasitic (most famous of which are ticks), but not all. For example, about half of the 10,000 known species in the suborder Mesos ...

Sclerosis (medicine)
Sclerosis (from Greek σκληρός ''sklērós'', "hard") is the stiffening of a tissue or anatomical feature, usually caused by a replacement of the normal organ-specific tissue with connective tissue. The structure may be said to have undergone sclerotic changes or display sclerotic lesions, which refers to the process of sclerosis. Common medical conditions whose pathology involves sclerosis include: * Amyotrophic lateral sclerosis—also known as Lou Gehrig's disease or motor neurone disease—a progressive, incurable, usually fatal disease of motor neurons. * Atherosclerosis, a deposit of fatty materials, such as cholesterol, in the arteries which causes hardening. * Focal segmental glomerulosclerosis is a disease that attacks the kidney's filtering system ( glomeruli) causing serious scarring and thus a cause of nephrotic syndrome in children and adolescents, as well as an important cause of kidney failure in adults. * Hippocampal sclerosis, a brain damage often seen ...

Mauritius
Mauritius ( ; french: Maurice, link=no ; mfe, label=Mauritian Creole, Moris ), officially the Republic of Mauritius, is an island nation in the Indian Ocean about off the southeast coast of the African continent, east of Madagascar. It includes the main island (also called Mauritius), as well as Rodrigues, Agaléga and St. Brandon. The islands of Mauritius and Rodrigues, along with nearby Réunion (a French overseas department), are part of the Mascarene Islands. The main island of Mauritius, where most of the population is concentrated, hosts the capital and largest city, Port Louis. The country spans and has an exclusive economic zone covering . Arab sailors were the first to discover the uninhabited island, around 975, and they called it ''Dina Arobi''. The earliest discovery was in 1507 by Portuguese sailors, who otherwise took little interest in the islands. The Dutch took possession in 1598, establishing a succession of short-lived settlements over a period of about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mites
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are predators or parasites. This last type includes the commercially destructive '' Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two distinct groups of ara ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
