Rhabdochlamydia
''Candidatus'' Rhabdochlamydia is a genus of intracellular bacteria and the sole genus in the family ''Candidatus'' Rhabdochlamydiaceae. As a ''Candidatus'' taxon, no-one has yet managed to culture them ''in vitro'' for deposition in a culture collection. Two ''Rhabdochlamydia'' species have been characterized and validly proposed. Their ribosomal RNA genes are 96.3% identical. These gene sequences are 82%–87% identical to those of most Chlamydiales. These data and analysis of ''Rhabdochlamydia'' morphology indicates that these species belong to the bacterial order Chlamydiales. Species The genus consists of the following two valid species: * ''Candidatus'' Rhabdochlamydia crassificans Kostanjšek et al. 2004 – detected in the cockroach ''Blatta orientalis'' * ''Candidatus'' Rhabdochlamydia porcellionis Corsaro et al. 2006 – detected in hepatopancreas of the woodlouse ''Porcellio scaber'' See also * List of bacteria genera This article lists the genera of the bacter ...

Chlamydiales
The bacterial order Chlamydiales includes only obligately intracellular bacteria that have a chlamydia-like developmental cycle of replication and at least 80% 16S rRNA or 23S rRNA gene sequence identity with other members of Chlamydiales. Chlamydiales live in animals, insects, and protozoa. Currently, the order Chlamydiales includes the families Chlamydiaceae, Simkaniaceae, and Waddliaceae, which have Gram-negative extracellular infectious bodies (EBs), and Parachlamydiaceae, which has variable Gram staining of EBs. The family Rhabdochlamydiaceae has been proposed.

Chlamydiota
The Chlamydiota (synonym Chlamydiae) are a bacterial phylum and class whose members are remarkably diverse, including pathogens of humans and animals, symbionts of ubiquitous protozoa, and marine sediment forms not yet well understood. All of the Chlamydiota that humans have known about for many decades are obligate intracellular bacteria; in 2020 many additional Chlamydiota were discovered in ocean-floor environments, and it is not yet known whether they all have hosts. Historically it was believed that all Chlamydiota had a peptidoglycan-free cell wall, but studies in the 2010s demonstrated a detectable presence of peptidoglycan, as well as other important proteins. Among the Chlamydiota, all of the ones long known to science grow only by infecting eukaryotic host cells. They are as small as or smaller than many viruses. They are ovoid in shape and stain Gram-negative. They are dependent on replication inside the host cells; thus, some species are termed obligate intracellula ...

Woodlouse
A woodlouse (plural woodlice) is an isopod crustacean from the polyphyleticThe current consensus is that Oniscidea is actually triphyletic suborder Oniscidea within the order Isopoda. They get their name from often being found in old wood. The first woodlice were marine isopods which are presumed to have colonised land in the Carboniferous, though the oldest known fossils are from the Cretaceous period. They have many common names and although often referred to as terrestrial isopods, some species live semiterrestrially or have recolonised aquatic environments. Woodlice in the families Armadillidae, Armadillidiidae, Eubelidae, Tylidae and some other genera can roll up into a roughly spherical shape ( conglobate) as a defensive mechanism; others have partial rolling ability, but most cannot conglobate at all. Woodlice have a basic morphology of a segmented, dorso-ventrally flattened body with seven pairs of jointed legs, specialised appendages for respiration and like ...

Porcellio Scaber
''Porcellio scaber'' (otherwise known as the common rough woodlouse or simply rough woodlouse), is a species of woodlouse native to Europe but with a cosmopolitan distribution. They are often found in large numbers in most regions, with many species (shrews, centipedes, toads, spiders and even some birds) preying on them. Taxonomy One subspecies, '' Porcellio scaber lusitanus'', is currently recognized. Two other subspecies were historically deemed valid but are no longer recognized. ''P. s. americanus'', described in 1932, was considered endemic the Americas. ''P. s. japonicus'' was described in 1928 and believed to be endemic to Japan. Both subspecies were synonymized with the nominate in 2020. Distribution ''Porcellio scaber'' is found across Central and Western Europe. In the United Kingdom, it is one of the "big five" species of woodlice. It has also colonised North America, South Africa and other regions including the remote sub-Antarctic Marion island, largely th ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Hepatopancreas
The hepatopancreas, digestive gland or midgut gland is an organ of the digestive tract of arthropods and molluscs. It provides the functions which in mammals are provided separately by the liver and pancreas, including the production of digestive enzymes, and absorption of digested food. Arthropods Arthropods, especially detritivores in the Order Isopoda, Suborder Oniscidea (woodlice), have been shown to be able to store heavy metals in their hepatopancreas. This could lead to bioaccumulation through the food chain and implications for food web destruction, if the accumulation gets high enough in polluted areas; for example, high metal concentrations are seen in spiders of the genus ''Dysdera'' which feed on woodlice, including their hepatopancreas, the major metal storage organ of isopods in polluted sites. Molluscs The hepatopancreas is a centre for lipid metabolism and for storage of lipids in gastropods.Böer M., Graeve M. & Kattner G. (2006). "Exceptional long-term s ...

Intracellular Bacteria
Intracellular bacteria are bacteria, which have the capability to enter and survive within the cells of the host organism. Many of them are capable of growth extracellularly, but some of them can grow and reproduce only intracellularly (obligate intracellular parasites). Besides bacteria, there are other kinds of intracellular microorganisms. Examples of non-obligate intracellular bacteria include members of the genera ''Brucella'', ''Legionella'', ''Listeria'', and '' Mycobacterium''. Examples of obligate intracellular bacteria include members of the order Rickettsiales and members of the genus '' Mycoplasma''. See also * Endosymbiont An ''endosymbiont'' or ''endobiont'' is any organism that lives within the body or cells of another organism most often, though not always, in a mutualistic relationship.

Blatta Orientalis
__NOTOC__ The oriental cockroach (''Blatta orientalis''), also known as the waterbug (as they live in damp areas) or black cockroaches (as their bodies are mostly dark), is a large species of cockroach, adult males being and adult females being . It is dark brown or black in color and has a glossy body. The female has a somewhat different appearance from the male, appearing to be wingless at a casual glance, but is brachypterous, having non-functional wings just below her head. She has a wider body than the male. The male has long wings, which cover three quarters of the abdomen and are brown in color, and has a narrower body. Both of them are flightless. The female oriental cockroach looks somewhat similar to the Florida woods cockroach and may be mistaken for it. Originally endemic to the Crimean Peninsula and the region around the Black Sea and the Caspian Sea, its distribution is now cosmopolitan. Habitat Oriental cockroaches tend to travel somewhat more slowly than other s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
