Visna virus of sheep and arthritis-encephalitis virus of goats are serologically related but genetically distinct retroviruses which cause slowly progressive diseases in their natural hosts. To localize homologous regions of the DNAs of these two viruses, we constructed a physical map of caprine arthritis-encephalitis virus DNA and aligned it with the viral RNA. Cloned probes of visna virus DNA were then used to localize regions of homology with the caprine arthritis-encephalitis virus DNA. These studies showed homology in the 5 region of the genome encompassing U5 and the gag and pol genes and also in a small region in the env gene. These findings correlate with biological data suggesting that the regions of the DNA which are homologous may be responsible for virus group characteristics such as the closely related virus core antigens. Regions which did not show homology such as large sections in the env gene may represent unique sequences which control highly strain-specific characteristics ...
The aim of the present transversal descriptive study was to determine the exposure and risk factors associated with caprine arthritis-encephalitis virus (CAEV) in southern Spain. A total of 3,312 serum samples were collected from goat belonging to three different breeds coming from 48 flocks located in different geographic areas from southern Spain. In addition, health and productive parameters were surveyed during the visit to the herds. Serum samples were analysed by INgezim Maedi Screening (Ingenasa®) ELISA kit. The total percentage of herds exposed to CAEV was 87.71% (CI95 78.42-97.00). A total of 733 goats were seropositive with overall seroprevalence of 23.22% (CI95 21.78-24.65). The intraherd seroprevalence was 20.82%±24.07. Multivariate logistic regression showed significant association between CAEV and the next variables: (i) herd size (P,0.0001; OR: 2.07; CI95: 1.73-2.50), (ii) kidding area (P,0.0020; OR: 1.38; CI95: 1.13-1.69), (iii) cleaning and disinfection program (P,0.0067; OR: ...

CAPRINE arthritis-encephalitis (CAE) is an important infectious disease that contributes to low productivity of goat herds in developing countries. Many factors, such as breed and production system, have been reported to interfere in its occurrence. Nevertheless, the effect of farmer association (cooperatives) in its control has never been investigated. Therefore, the goal of this study was to report a difference of caprine arthritis-encephalitis virus (CAEV) seroreactivity by agar gel immunodiffusion test (AGID) in associated versus non-associated farmers in the same region in Rio de Janeiro State, Brazil. A total of 562 blood samples were sampled from 28 goat herds. Animals were randomly selected from each herd. A total 79 of 562 (14.0 per cent) serum samples were reactive for CAEV. According to the serology, 80 per cent of the herds belonging to independent farmers presented at least one seroreactive animal, with a herd level average among those of 25.7 per cent (11.1 to 62.5 per cent; median ...

Caprine arthritis encephalitis virus (CAEV) and Visna-Maedi virus (MVV) are lentivirus that cross the species barriers between goats and sheep and are therefore referred to as small ruminant lentiviruses (SRLV). In our laboratory we study different aspects of these fascinating viruses in various projects. ...
A retrospective study of brain lesions in goats was conducted to identify the range of lesions and diseases recognized and to make recommendations regarding the best tissues to examine and tests to conduct in order to maximize the likelihood of making a definitive diagnosis in goats that may have had clinical signs referable to the brain. One hundred thirty-nine goats with a brain lesion were identified. The most common lesion, in 52.5% of the goats, was suppurative inflammation. Approximately two-thirds of these goats had encephalitic listeriosis. Other goats were found to have suppurative inflammation in association with septicemia, pituitary abscesses, dehorning injury, and otitis. Thirty goats (21.6%) were diagnosed with polioencephalomalacia. Twenty-one goats (15.1%) were diagnosed with nonsuppurative inflammation. In more than half of these goats, no definitive diagnosis was made, while 8 were infected with Caprine arthritis encephalitis virus and 1 with Rabies virus. However, few goats ...

Samir "Sam" Chachoua is an Australian alternative medicine practitioner, trained as a medical doctor. He is not actively licensed to practice medicine in Australia or the United States. Chachoua offers treatments in Mexico that he claims to be effective alternative medicine vaccine therapies for cancer and HIV, among other diseases. His claims lack scientific support, and are disputed by medical doctors. Chachouas treatments depend on theories he has named, including "Induced Remission Therapy" and "The Nemesis Theory", i.e. "for every disease there is an anti-disease organism capable of destroying it and restoring health". For treatment of HIV, Chachoua vaccinates patients with Caprine arthritis encephalitis virus, which is known to cross-react immunologically with HIV. He claims to have eradicated HIV from the nation of Comoros in 2006. This claim has been refuted by Savlator Niyonzima, the UNAIDS country director of Madagascar, Comoros, Mauritius, and Seychelles. As of 2012, the adult HIV ...
But what if he could, tho?. What would this super awesome therapy THE MAN doesnt want you to know about look like? How would it work?. That would be a fun and educational game to play!. Okay, to play this game you first have to understand what CAEV is. Caprine arthritis-encephalitis virus is a retrovirus that infects goats. It is like HIV in the sense that they are both lentiviruses, that is, more complex (more genes) retroviruses. They both share the standard gag, pol, and env genes all retroviruses have, plus a few accessory genes: rev, tat, and vif. HIV also has a few more.. But while there are similarities, CAEV and HIV are not the same any more than you and blue whales are the same (I tried to align an amino acid sequence of a CAEV Env with an HIV-1 Env, and the program was like Nuh uh. Dees dont go together.). So: How could CAEV be used to cure HIV?. 1- Anti-CAEV antibodies from goats could stop HIV!. Dr. Whatever said, specifically, that he looked for the absence of disease. ...
Caprine arthritis encephalitis (CAE) virus is a member of the small ruminant lentiviruses (also includes ovine progressive pneumonia, or OPP, of sheep), which may lead to chronic disease of the joints, and on rare occasions, encephalitis in goat kids less than six months of age. The CAE virus is intimately associated with white blood cells; therefore, any body secretions that contain blood cells are potential sources of virus to other goats in the herd. Since not all goats that become infected with CAE virus develop clinical disease, it is important to test goats routinely for infection by means of a serologic test that detects viral antibodies in the serum.

The cost and effort involved in ridding a goat herd of the Caprine Arthritis and Encephalitis (CAE) Virus are well worth the investment according to a new animal disease model that puts real costs on the financial impact the disease can have. CAE is a production limiting disease that infects cells of the lung, central nervous system, joints and mammary glands.. A low impact outbreak of CAE in a 100 head goat breeding and meat herd could cost the operation up to $710 and a high impact outbreak up to $28,900. Those figures were generated by the model based on 2010 cost and revenue data provided by real Ontario producers.. Click here to access the On-Farm Cost of Disease Calculator. Producers must input a series of data in the spreadsheet, such as feed costs, average daily gain, mortality rates and others depending on the particular commodity, in order for the model to generate results.. Funding was provided in part through Growing Forward, a federal-provincial-territorial initiative. The ...

What producers can do to prevent introduction and reduce transmission. Slowly progressive illnesses like Caprine Arthritis-Encephalitis (CAE) in goats are major production limiting diseases that can be a source of significant stress and economic loss for farmers.. Once an animal has the CAE virus, it results in a persistent, lifelong infection. Most goats dont show any symptoms but can be carriers, which means they can transmit the disease to other animals in the herd. There is currently no treatment or vaccine, and the prevalence across Ontario is unknown.. Thats why Ontario Goat has recently partially funded two research projects at the University of Guelph focused on learning more about the disease, its prevalence and how it behaves on Ontario goat farms.. Determining CAE prevalence. A preliminary study of 45 randomly selected Ontario goat herds - 30 dairy goat breeders and 15 meat goat operations - was carried out in 2012 to determine how widespread the CAE virus infection is in the ...

This case report describes a Yersinia pseudotuberculosis infection in an adult, female single pet goat kept on a dairy cattle farm. The doe showed the habitus of a chronically ill animal, with poor body condition and chronic diarrhoea, when presented at the clinic. The animal displayed a grave manifestation of the disease with severe enteritis and typhlocolitis, lymphadenitis and some up to 10 cm in diameter pyogranulomatous inflammation in the liver, spleen, pancreas, omasum and the intestinal lymph nodes. All other causative agents that might explain the described signs were ruled out (Corynebacterium pseudotuberculosis, Mycobacterium avium subspecies paratuberculosis, tuberculosis, tumorous alterations, foreign bodies, caprine arthritis encephalitis). Goats seem to be vulnerable for yersiniosis, but in contrast to this case report, in most cases, Yersinia enterocolitica, and not Y. pseudotuberculosis, can be proved as infectious cause of yersiniosis. ...

Maedi visna virus (MVV) vertical transmission in sheep via infected colostrums is a very important route of infection in lambs. To verify colostral transmission and to study early viral entry in lambs, colostrum samples, and small intestine and mesenteric lymph nodes of lambs born from experimentally infected ewes were examined by histopathology, immunohistochemistry (IHC) and in situ hybridisation (ISH) studies. In particular, newborn lambs were naturally fed maternal colostrum and humanely killed at 10, 24, 48, 72, 96 h and 7 and 10 days after birth; two caesarian-derived lambs served as uninfected controls. No lesions suggestive of MVVinfection were found, but marked immunoreactions for MVV capsid antigen (CA, p28) were detected in lambs fed maternal colostrum and in macrophages cultured from colostrum. IHC results in lambs suggest a initial viral absorption by intestinal epithelial cells at the tip of the villi, passage to mononuclear cells in the lamina propria and involvement of ileum ...
Maedi visna virus (MVV) is a retrovirus that is member of the Lentivirus genus. MVV infects sheep and goats and causes progressive pneumonia or paralysis, leading to death. Since the discovery of the receptor for Human immunodeficiency virus (HIV), Simian immunodeficiency virus (SIV) and Feline immunodeficiency virus (FIV) all include the chemokine receptor CXCR4, it has been postulated that all members of the Lentivirus share a common mechanism of entry that involves the use of CXCR4. With the use of syncytia assays, infection-, inhibition- and enhancement studies, it was shown that CXCR4 is not a common lentivirus receptor. U87 and HOS cells, both celllines lacking CXCR4, were susceptible to infection. However, cells transfected with CD4 and CXCR4 showed an increased syncytia formation and the presence of CD¤ and CXCR4 augments virus-induced cell fusion. The nature of MVV receptor is still not known, but our data suggest the use of CD4 and/or CXCR4 as accessory molecules or as part of a ...
Cell Membrane Cell membrane integrity  vital for proper cell functioning. Most cells can only withstand transient ruptures of the cell membrane. If the cell membrane suffers massive breaches -loses the ability to accumulate and contain vital components and will be subject to outside toxins. There is a term for cells that suffer massive cell membrane trauma - Dead Cells.
Contributor Comment: This is the respiratory form of small ruminant lentiviruses. This respiratory disease is caused by a group of non-oncogenic exogenous retroviruses of the genus lentivirus that target immune cells, mainly macrophages. The Small Ruminant Lentiviruses are a group of highly related single stranded RNA viruses with high mutational potential that affect mainly sheep but also goats.1 These viruses induce chronic inflammation that usually remains subclinical. When it becomes clinical, the disease can express mainly in four different locations: lung, joints (mainly carpus), central nervous system and mammary gland.3 The expression of each form as well as the gravity of the lesion depends on host immune response and the viral factors. The respiratory form, termed maedi or ovine progressive pneumonia, is the most common presentation of the disease in sheep.1 The process consists of an afebrile chronic progressive pneumonia that leads to weight loss and marked dyspnea. Grossly, the ...

The chlor-alkali membrane process is one of the largest in industrial electrolysis with the production of roughly 40 million metric tons of both chlorine and caustic soda per year. Chlorine is used predominantly for the production of vinyl chloride monomer, which in turn is used for the production of poly vinyl chloride (PVC). Current density in membrane-cell technology has increased dramatically during the last decade as the membranes themselves have improved. This results in lower investment costs for greater production. However, the increase in current density implies an increase in power consumption if nothing is done to dampen the voltage increase. Advances in cell design including increased internal convection, decreased ohmic losses, and better membranes have allowed for large increases in current density with small increases in cell voltage. This example describes the current-density distribution in realistic anode and cathode structures in a membrane cell.. ...
