Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arachnid
Arachnida () is a class of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons. Almost all adult arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word (''aráchnē'', 'spider'), from the myth of the hubristic human weaver Arachne, who was turned into a spider. Almost all extant arachnids are terrestrial, living mainly on land. However, some inhabit freshwater environments and, with the exception of the pelagic zone, marine environments as well. They comprise over 100,000 named species, of which 47,000 are species of spiders. Morphology Almost all adult arachnids have eight legs, unlike adult inse ...

Acari
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 arachni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesostigmata
Mesostigmata is an order of mites belonging to the Parasitiformes. They are by far the largest group of Parasitiformes, with over 8,000 species in 130 families. Mesostigmata includes parasitic as well as free-living and predatory forms. They can be recognized by the single pair of spiracles positioned laterally on the body. The family with the most described species is Phytoseiidae. Other families of note are Diplogyniidae, Macrochelidae, Pachylaelapidae, Uropodidae and Veigaiidae. Amongst the best known species are ''Varroa destructor'', an economically important parasite of honey bees, as well as the red mite (''Dermanyssus gallinae'') a parasite of poultry, most commonly chickens. Description Mesostigmata are mites ranging from 0.12-4 mm long (0.2-4 mm according to another source). They have a pair of stigmatal openings above legs III-IV usually associated with a peritrematal groove. The gnathosoma has a sclerotised ring around the bases of the chelicerae (basis capitul ...

House Mouse
The house mouse (''Mus musculus'') is a small mammal of the order Rodentia, characteristically having a pointed snout, large rounded ears, and a long and almost hairless tail. It is one of the most abundant species of the genus '' Mus''. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point that truly wild populations are significantly less common than the semi-tame populations near human activity. The house mouse has been domesticated as the pet or fancy mouse, and as the laboratory mouse, which is one of the most important model organisms in biology and medicine. The complete mouse reference genome was sequenced in 2002. Characteristics House mice have an adult body length (nose to base of tail) of and a tail length of . The weight is typically . In the wild they vary in color from grey and light brown to black (individual hairs are actually agouti coloured), but domesticated fancy mice and laboratory mice ar ...

Rodent Mite Dermatitis
Rodent mite dermatitis (also known as rat mite dermatitis) is an often unrecognized ectoparasitosis occurring after human contact with haematophagous mesostigmatid mites that infest rodents, such as house mice, rats and hamsters. The condition is associated with the tropical rat mite (''Ornithonyssus bacoti''), spiny rat mite (''Laelaps echidnina'') and house mouse mite (''Liponyssoides sanguineus'') which opportunistically feed on humans. Rodent mites are capable of surviving for long periods without feeding and travelling long distances when seeking hosts. Cases have been reported in homes, libraries, hospitals and care homes. A similar condition, known as gamasoidosis, is caused by avian mites. Symptoms and signs Rodent mite bites leave multiple groups or individual small itchy papules (around 1–2 mm in diameter) on the skin (papular urticaria). These are found mostly "on the upper extremities, neck, upper trunk and face". Diagnosis Diagnosis requires species iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rickettsia Akari
''Rickettsia akari'' is a species of ''Rickettsia'' which causes rickettsialpox. After a 1946 outbreak of a rickettsial-type disease at an apartment complex in Kew Gardens, Queens, an investigation was performed to identify the source of the infections. The incinerators in the buildings were not operated on a daily basis, leading to a buildup in food waste and attracting mice that were rampant throughout the building. The ''Mus musculus'' mice were found to be carrying mites, identified as the house mouse mite, ''Allodermanyssus sanguineus''. Self-trained entomologist Charles Pomerantz asked permission to search the site and found the mites at various sites throughout the building, with blood-engorged mites found near chutes leading to the incinerator. The mites were collected and brought to a laboratory of the United States Public Health Service, which found in the mites an organism that had also been isolated from the mice, and from the blood of individuals infected with the dis ...

Rickettsialpox
Rickettsialpox is a mite-borne infectious illness caused by bacteria of the genus ''Rickettsia'' (''Rickettsia akari''). Physician Robert Huebner and self-trained entomologist Charles Pomerantz played major roles in identifying the cause of the disease after an outbreak in 1946 in a New York City apartment complex, documented in "The Alerting of Mr. Pomerantz," an article by medical writer Berton Roueché. Although it is not transmitted by a tick (a characteristic of spotted fever), the bacterium is a part of the spotted fever group of ''Rickettsia'', and so this condition is often classified with that group. Signs and symptoms The first symptom is a bump formed by the bite, eventually resulting in a black, crusty scab. Many of the symptoms are flu-like including fever, chills, weakness and achy muscles but the most distinctive symptom is the rash that breaks out, spanning the infected person's entire body. Transmission The bacteria are originally found in mice and cause mites ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
