How is hog cholera treated?
The disease has been eradicated from the United States. In countries in which control has been established, the disease must be reported, infected animals are compulsorily slaughtered, and the premises of sick animals are quarantined. Control is mainly by vaccination.
How long does hog cholera last?
Pigs develop protective immunity one week to ten days after vaccination and the immunity lasts two to three years (i.e. the lifetime of many sows and boars). Piglets which are suckled by vaccinated sows receive colostral protection which lasts about 6-8 weeks.
How did the US eradicate hog cholera?
The 1961 decision to eradicate hog cholera came during large-scale field tests conducted by ARS in Florida, Iowa, and Georgia. The ARS Hog Cholera Research Station at Live Oak, Fla., tested modified live-virus vaccines and anti-hog-cholera serum on about 60,000 swine on 1,500 Florida farms.
Is hog cholera a blood disease?
Classical swine fever, also known as hog cholera, is a highly contagious viral disease of pigs. The disease is spread by direct or indirect contact through blood, secretions and excretions.
What causes hog-cholera in pigs?
Classical swine fever (CSF), also known as hog cholera, is a contagious viral disease of domestic and wild swine. It is caused by a virus of the genus Pestivirus of the family Flaviviridae, which is closely related to the viruses that cause bovine viral diarrhoea in cattle and border disease in sheep.
Can swine fever be cured?
No treatment or effective vaccine exists for African swine fever. It has proven difficult to control transmission of the disease. Often, movement restriction and herd depopulation are necessary control measures because of how quickly and easily the virus spreads.
What causes hog cholera in pigs?
How can cholera be prevented in hogs?
Hog cholera can be successfully prevented by the use of anti-hog-cholera serum. It should ·be used as a preventive and not as a cure, although its curative properties should not be entirely overlooked.
What is hog cholera vaccine?
Live freeze-dried vaccine, THIVERVAL strain Active immunization of pigs against Classical Swine Fever (Hog Cholera) COGLAPEST® is the unique attenuated live vaccine containing the Thiverval strain. The protection is at the same time fast, strong and long lasting.
Is there a vaccine for hog cholera?
Long-term protection against hog cholera can be conferred by living vaccines. Some modified living vaccines can be either given alone or with serum. Active immunity of this type is of two years or more duration. The inactivated or killed virus vaccines are also used to produce active immunity.
Do pigs spread cholera?
Classical swine fever (CSF) or hog cholera (also sometimes called pig plague based on the German word Schweinepest) is a highly contagious disease of swine (Old World and New World pigs)….Classical swine fever.

Is hog cholera a virus disease?
But when Dr. Dorset tested a serum from that bacterium during an 1897 outbreak in Iowa, injected hogs still died of cholera. He therefore questioned prevailing scientific opinion, and about 6 years later proved that hog cholera is a virus disease.
Is anti-hog cholera serum a reliable preventive agent?
“The Bureau of Animal Industry for many years has made a study of the disease [hog cholera] and finally evolved the ‘anti-hog-cholera serum,’ which ca be regarded as the only known reliable preventive agent. It is the only agent which has been proved to have curative properties.
How long does immunity to cholera last in hogs?
Dr. Dorset, Dr. McBryde, and W.B. Niles found that serum from the blood of immune hogs conferred immunity lasting only a few weeks to other hogs. But injection of the BAI hyperimmune serum plus injection of virus gave lifelong protection against hog cholera to most hogs.
What research discovery led to the eradication of hog cholera?
A key research discovery leading to control and eventual eradication of hog cholera was made in l903. Marion Dorset of USDA’s Bureau of Animal Industry (BAI) demonstrated that hog cholera is caused by an ultramicroscopic virus, and hogs recovered from the disease are immune for life. Almost 20 years earlier,…
