Bertiella Mucronata
''Bertiella mucronata'' is a species of '' Bertiella'', a type of cestode tapeworms known to cause Bertielliasis. It belongs to the genus ''Bertiella'', family Anoplocephalidae. This is one of two species of ''Bertiella'' that can cause the condition in humans (the other being ''Bertiella studeri ''Bertiella studeri'' is a species of '' Bertiellia'', a type of cestodes (tapeworms). It is a parasite of primates which was first described in the rhesus macaque (''Macaca mulatta'') in 1940. The intermediate host are oribatid mites, which ing ...''). Epidemiology The genus Bertiella has 29 cestode species that infect primarily non-human primates. B. studeri and B. mucronata can cause the condition in humans. It usually occurs in children with close contact to non-human primates. This is known to occur in Africa, Asia, Oceania, South America and Cuba. Life cycle/reproduction The life cycle of Bertiella species has a two-host life cycle. An arthropod (such as a mite) serves a ...

Bertiella (flatworm)
''Bertiella'' is a genus of cestode tapeworm parasites that primarily infects nonhuman primates, rodents and Australian marsupials. Infections by ''Bertiella'' are known as bertielliasis. Occasional human infections have been documented by one of two species: ''Bertiella studeri'', or ''Bertiella mucronata''. ''Bertiella'' transmission is through oribatid mites that are present in the soil of problem areas, and can be easily prevented by avoiding contact with nonhuman primates, rodents and soil in these areas. Pathology Of 29 different ''Bertiella'' species, only two can infect humans: ''Bertiella studeri'' (majority of human cases), and ''Bertiella mucronata''. Infected patients are usually asymptomatic. Often individuals will have no fever and show no signs of internal organ damage or distress. Although symptoms are unique to each individual, an infected human may suffer from gastrointestinal irritation, diarrhea, abdominal pain, anorexia, weight loss, vomit and/or consti ...

Cestode
Cestoda is a Class (biology), class of parasitic worms in the flatworm phylum (Platyhelminthes). Most of the species—and the best-known—are those in the subclass Eucestoda; they are ribbon-like worms as adults, known as tapeworms. Their bodies consist of many similar units known as proglottids—essentially packages of eggs which are regularly shed into the environment to infect other organisms. Species of the other subclass, Cestodaria, are mainly fish infecting parasites. All cestodes are parasitism, parasitic; many have complex Life history theory, life histories, including a stage in a Host (biology)#Definitive and secondary hosts, definitive (main) host in which the adults grow and reproduce, often for years, and one or two intermediate stages in which the larvae develop in other hosts. Typically the adults live in the digestive tracts of vertebrates, while the larvae often live in the bodies of other animals, either vertebrates or invertebrates. For example, ''Diphyllob ...

Bertielliasis
Bertielliasis is the infection of '' Bertiella'', a cestode tapeworm parasite that primarily infects nonhuman primates, rodents and Australian marsupials. Occasionally, human infections have been documented by one of two species: ''Bertiella studeri'', or '' Bertiella mucronata''. Of 29 different ''Bertiella'' species, only these two can infect humans. These infections present with symptoms similar to most tapeworm cases, and are frequently misdiagnosed. ''Bertiella'' transmission is through oribatid mites that are often present in the soil of problem areas, and can be easily prevented by avoiding contact with nonhuman primates, rodents and soil in these areas. Signs and symptoms Bertielliasis can be asymptomatic, or present with symptoms similar to many other tapeworms. These can include epigastric pain after meals accompanied by nausea, diarrhea, anorexia, loss of weight and, generally, a tender abdomen. Fever is not typically a symptom, but there are also reported cases o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bertiella Studeri
''Bertiella studeri'' is a species of '' Bertiellia'', a type of cestodes (tapeworms). It is a parasite of primates which was first described in the rhesus macaque (''Macaca mulatta'') in 1940. The intermediate host are oribatid mites, which ingest the eggs, and are themselves ingested by the vertebrate host. Oribatid mites infected with Bertiella transfer the developmental cysticercoid stage to a human host through tissue feeding. This is one of two species of ''Bertiella'' that cause Bertielliasis in humans (the other being '' Bertiella mucronata''). The majority of human cases occur in individuals who have some level of contact with non-humanprimates. Geographic distribution of cases demonstrate ''Bertiellia'' infection within countries from Asia, Africa, and the Americas. Morphology An adult ''B. studeri'' tapeworm measures 10–30 cm long, and is 1 cm wide. The adult develops in the small intestine of the primate host. Once the adult develops in the small inte ...
