Circoviridae is a family of DNA viruses. Birds and mammals serve as natural hosts. There are 101 species in this family,assigned to 2 genera. Diseases associated with this family include:PCV-2:postweaning multisystemic wasting syndrome;CAV:chicken infectious anemia.
Porcine circoviral disease (PCVD),also known as porcine circovirus associated disease (PCVAD),is a disease seen in domestic pigs. This disease causes illness in piglets,with clinical signs including progressive loss of body condition,visibly enlarged lymph nodes,difficulty in breathing,and sometimes diarrhea,pale skin,and jaundice. PCVD is very damaging to the pig-producing industry and has been reported worldwide. PCVD is caused by Porcine circovirus 2 (PCV-2).
Betaarterivirus suid 1,commonly Porcine reproductive and respiratory syndrome virus (PRRSV),is a virus that causes a disease of pigs,called porcine reproductive and respiratory syndrome (PRRS),also known as blue-ear pig disease. This economically important,panzootic disease causes reproductive failure in breeding stock and respiratory tract illness in young pigs.
Porcine circovirus (PCV) is a group of four single-stranded DNA viruses that are non-enveloped with an unsegmented circular genome. They are members of the genus Circovirus that can infect pigs. The viral capsid is icosahedral and approximately 17 nm in diameter.
Porcine parvovirus (PPV),a virus in the species Ungulate protoparvovirus 1 of genus Protoparvovirus in the virus family Parvoviridae,causes reproductive failure of swine characterized by embryonic and fetal infection and death,usually in the absence of outward maternal clinical signs. The disease develops mainly when seronegative dams are exposed oronasally to the virus anytime during about the first half of gestation,and conceptuses are subsequently infected transplacentally before they become immunocompetent. There is no definitive evidence that infection of swine other than during gestation is of any clinical or economic significance. The virus is ubiquitous among swine throughout the world and is enzootic in most herds that have been tested. Diagnostic surveys have indicated that PPV is the major infectious cause of embryonic and fetal death. In addition to its direct causal role in reproductive failure,PPV can potentiate the effects of porcine circovirus type II (PCV2) infection in the clinical course of postweaning multisystemic wasting syndrome (PMWS).
Psittacine beak and feather disease (PBFD) is a viral disease affecting all Old World and New World parrots. The causative virus—beak and feather disease virus (BFDV)—belongs to the taxonomic genus Circovirus,family Circoviridae. It attacks the feather follicles and the beak and claw matrices of the bird,causing progressive feather,claw and beak malformation and necrosis. In later stages of the disease,feather shaft constriction occurs,hampering development until eventually all feather growth stops. It occurs in an acutely fatal form and a chronic form.
Viremia is a medical condition where viruses enter the bloodstream and hence have access to the rest of the body. It is similar to bacteremia,a condition where bacteria enter the bloodstream. The name comes from combining the word "virus" with the Greek word for "blood" (haima). It usually lasts for 4 to 5 days in the primary condition.
David Mathayo David is a Tanzanian CCM politician and Member of Parliament for Same West constituency since 2005. He is the current Minister of Livestock and Fisheries Development.
Veterinary virology is the study of viruses in non-human animals. It is an important branch of veterinary medicine.
Sokoine University of Agriculture (SUA) is a public university in Morogoro,Tanzania,specializing in agriculture. The university is named after the country's second prime minister Edward Sokoine.
ATCvet code QI09Immunologicals for Suidae is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System for veterinary medicinal products,a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products for veterinary use. Subgroup QI09 is part of the anatomical group QI Immunologicals.
Porcine adenovirus is a virus in the family Adenoviridae. It causes mild gastrointestinal diseases in pigs and is thought to contribute to multifactorial porcine respiratory diseases complexes. Several strains of the virus can be found worldwide,and transmission occurs horizontally by the fecal-oral route.
Blue eye disease is caused by La Piedad Michoacán Mexico virus (LPMV),the only member virus of the species Porcine orthorubulavirus in the Paramyxoviridae family. Synonyms for the disease include "Blue Eye Syndrome" and "Porcine Paramyxovirus Blue Eye Disease",and "La Piedad Michoacán Paramyxovirus Infection".
Circovirus is a genus of viruses,in the family Circoviridae. Birds and pigs serve as natural hosts,though dogs have been shown to be infected as well. It is a single stranded DNA virus (ssDNA). There are 49 species in this genus. Some members of this genus cause disease:PCV-1 is non pathogenic,while PCV-2 causes postweaning multisystemic wasting syndrome (PMWS).
James E. Collins is an American veterinary physician and academic. He is the professor of medicine at the University of Minnesota and its Director of the veterinary diagnostic laboratory.
Betaarterivirus suid 2 is a species of enveloped,positive-strand RNA viruses which infect domestic pigs. Members of the species are also known as porcine reproductive and respiratory syndrome virus 2. Member viruses are a type of the porcine reproductive and respiratory syndrome viruses (PRRSV). The two types of PRRSV are distinguished by which genomic cluster they are associated with. Type 1 is associated with a LV cluster. Type 2 is associated with a VR2332 cluster.
Noble Banadda was a Ugandan biosystems engineer,researcher and academic,who was a professor of biosystems engineering at Makerere University,Uganda's largest and oldest public university. He was appointed a full professor in 2012 at age 37,one of the youngest persons in the history of the university to attain full professorship.
Xiang-Jin Meng,also known as X.J. Meng,is a Chinese-born American virologist. He is a university distinguished professor at Virginia Tech. He studies emerging,re-emerging and zoonotic viruses of veterinary and human public health significance. He was elected a member of the National Academy of Sciences in 2016,a Fellow of the National Academy of Inventors in 2014,a Fellow of the American Academy of Microbiology in 2012,and a Fellow of the American Association for the Advancement of Science.
The history of coronaviruses is an account of the discovery of the diseases caused by coronaviruses and the diseases they cause. It starts with the first report of a new type of upper-respiratory tract disease among chickens in North Dakota,U.S.,in 1931. The causative agent was identified as a virus in 1933. By 1936,the disease and the virus were recognised as unique from other viral disease. They became known as infectious bronchitis virus (IBV),but later officially renamed as Avian coronavirus.
