rinderpest is caused by
Rinderpest, once a common affliction, was caused by a specific virus that produced high fever and diarrhea; the disease was declared eradicated in 2011. In regions that depend on cattle for meat, dairy products, and animal traction, rinderpest has caused widespread food problems and serious economic and political damage. A murrain was any disease noted in cattle and rinderpest was known as steppe murrain since it wasthought of in Europe as a disease from the steppes between Europe and Asia. This is the question we will focus on first. [21] It is considered feasible to eradicate ovine rinderpest in 15 years.[8]. Mainly cattle and buffaloes, but also reported in sheep,goat and pigs . Indirect transmission is unlikely due to the thermolability of the virus. The outbreak in Burkina Faso in 1999 was caused by the lineage I group. The bloody diarrhea observed in the last stages of rinderpest is caused by replication of the virus in the gut mucosa. Due to efforts of the Global Rinderpest Eradication Program, the disease is believed to be nearly eradicated. Further disease control worldwide contributed to the green revolution in agricultural production. Rinderpest is an acute, contagious disease that causes high morbidity and mortality in cattle, buffalo, yak and other wildlife species.

[4], In 2017, the disease was reported to be affecting saiga in Mongolia, causing near-catastrophic herd depletion for the endangered species. [8] Incubation period is 3-5 days.[9]. They also vary according to the breed of sheep. The virus was transmitted by close direct or indirect contact. Photo It is spread by direct contact and commonly causes death in infected animals. The infection was probably introduced from Arabia or India. Photograph: Don Hammond/Rex Features Ian Sample , science correspondent Ovine rinderpest, also commonly known as peste des petits ruminants, is a contagious disease primarily affecting goats and sheep; however, camels and wild small ruminants can also be affected. These symptoms were followed within a few more days by discharges from the eyes … Rinderpest was a viral disease of cattle and other ruminants (domestic and wild) characterized by fever, erosive stomatitis, diarrhea, and high morbidity and mortality. Examination of the mouth shows ulceration of the buccal mucosae, especially on the inner face of the lips, and neighboring gum. Classification: OIE List A disease : Susceptible species: Cattle and buffaloes are highly susceptible. Lineage IV was long known as the Asian lineage, but has now spread to the African continent and become the most prevalent lineage of all. Four genotypes (lineages) of the virus are described. Dislike Bookmark. The long-distance spread is by sick animals. This virus has caused hundreds of millions of livestock deaths over hundreds of years. [12] A global eradication programme has been developed by the Food and Agriculture Organization of the United Nations and the World Organisation for Animal Health. The disease is highly contagious, and can have an 80–100% mortality rate in acute cases in an epizootic setting. The virus The virus that caused rinderpest was a member of the genus Morbillivirus, which also includes the measles and canine distemper viruses. One candidate they considered was disease. In acute cases, animals are recumbent, sometimes in self-auscultation position. Many students have ideas and questions but need time to formulate their idea or question into words. However, clinical signs vary in severity depending on the strain of rinderpest virus as It can cause illness in cloven-hooved (two-toed) animals, particularly cattle and buffalo. As of 2017, the disease is present in West Africa, part of Central Africa (Gabon, Central African Republic), East Africa (north of the Equator), the Middle East and the Indian subcontinent including Nepal and Myanmar. This disease is caused by the rinderpest virus (RPV) which is very similar to canine distemper virus and human measles virus, two very contagious diseases. Official agencies such as the FAO and OIE use the French name "peste des petits ruminants" with several spelling variants. Lineage III is generally found in East Africa. I… Rinderpest (RV) was an acute to subacute contagious viral disease of ruminants and pigs that could cause morbidity and mortality rates in excess of ninety per cent. Epidemic rinderpest, at its worst thefeared cattle plague, occurs when virus from an endemic or sporadically infected area is introducedto a population of cattle or other species that have little innate resilience to the clinical disease andwhich have low or non-existent herd immunity. Rinderpest was the first animal disease to be globally eradicated. Rinderpest was caused by a paramyxovirus (genus Morbillivirus) closely related to those that cause measles in humans and viral distemper in dogs. [12] Movement restrictions and slaughter of affected flocks may be required in an attempt to eradicate the disease.
