Fiebre Porcina Clásica

The definitive test for differentiation is the comparative neutralization test. The virus can range from high to low virulence, resulting in acute, subacute, chronic and persistent forms of the disease in infected swine. Several days after the first symptoms appear, the abdomen, inner thighs and ears may become cyanotic purplish discoloration.

Transfer of the virus can also occur through direct contact of pigs with infected animals; this can occur through the mucous membranes, conjunctiva, and skin abrasions.

Only a few animals in the herd may show signs of illness and these signs can resemble other swine diseases. For these individuals, they should check-in with farm personnel upon arrival and follow biosecurity measures while on the farm e.

Aerosol spread can occur in confined spaces; however the virus does not travel long distances in the air. Congenital infections with the pestiviruses that cause bovine virus diarrhea or border disease can resemble classical swine fever.

La mayor parte de Europa Occidental y Central Classical swine fever CSF was first confirmed in the UK inand spread rapidly until when steps were taken to control the disease. Younger animals often have higher mortality rates than adult pigs. Additional differentials include African swine fever, hemolytic disease of the newborn, thrombocytopenic purpura, anticoagulant e. Chronic infections are almost always fatal. The December CSF surveillance plan provides the rationale for this transition.

This can occur following feeding of contaminated garbage or meat products. Sources of virus include blood and all tissues, secretions and excretion saliva, urine, feces, semen of sick and dead animals. Finally, we will provide prevention and control measures for the disease and actions to take if CSF is suspected. In countries free of CSF, periodic surveillance is necessary to confirm freedom from infection.

In countries where classical swine fever is endemic, vaccines may be used to protect animals.

CSF was eradicated from Great Britain in Constant progress toward eradication has been made in Eastern Europe, stemming from guidelines developed for CSF control in individual states of Eastern Europe in InCSF was recognized in 36 countries, and was suspected of being present in two additional countries. Vehicles and equipment can serve as fomites for the spread of the virus.

Additionally, because pigs can be asymptomatic or can shed the virus before clinical signs are seen, newly purchased or returning animals should be quarantined a minimum of 30 days prior to introduction into the herd.

The disease has been reported in parts of Mexico. The figure shows a fast replicating, highly virulent oval and large plaque virus, and a slow replicating, lower virulence small and round plaques virus replicating on a cell plaque. Samples should only be sent under secure conditions and to authorized laboratories to prevent the spread of the disease.

Keeping health records on every animal is equally as important as it will help in the history and possible trace back if needed for the animals in the herd. On the farm, control will require quarantine and slaughter of affected and exposed swine. Thanawongnuwech, Veterinary Pathology-Chulalongkorn University with permission.

Cells infected with CSFV replicating on a cell culture monolayer. We will also talk about the economic impact the disease has had in the past and could have in the future.

Porcine reproductive and respiratory syndrome and porcine circovirus associated diseases especially porcine dermatitis nephritis syndrome should also be considered. The virus is sensitive to drying and ultraviolet light.

The cortex contains multiple petechiae and pale infarcts surrounded by hemorrhage. This is a less common route of transmission as is transfer by insect vectors. This may entail complete herd slaughter combined with area restrictions on pig movements, or vaccination depending on local disease control regulations.

The virus can be destroyed by cooking at temperatures of Hemorrhages can also occur in the skin. To make this website work, we log user data and share it with processors. The clinical signs of CSF vary with the strain of the virus and the susceptibility of the pigs.

Cuarentena Sacrificio While CSF has been eradicated from many countries, re-introduction is always a possibility. CSF can be distinguished by detecting the virus or its antigens in whole blood or tissue samples. They should be cleaned after each use. The mucosa is reddened and contains multiple discrete “button” ulcers surrounded by zones of hemorrhage.

Similar re-introductions of the disease have ocurred in the United Kingdomand other European countries No treatment should be attempted for pigs suspected with CSF. Passive reporting is conducted by private practitioners or producers, diagnosticians, slaughter plant inspectors of suspicious enfernedad with clinical signs similar to a foreign animal disease such as CSF.

Necrotic foci are common in the tonsils, sometimes with pustules and severe congestion. The incubation period ranges from 2 to 14 days.

Chronic disease symptoms include fever, anorexia, stunted growth, and alopecia; these symptoms may wax and wane for months. CSF can have a major impact on production, resulting in excessive morbidity and possibly mortality, as we al infertility and other deleterious health effects at the porcjnos level.

In a protein-rich environment, the virus is quite stable and can survive in refrigerated meat for months and frozen meat for years.

Confirmed cases can lead to a ban on the import and export of pigs and pork products to many different countries. The green areas indicate areas where CSF has never been reported.

This is especially important for those who have traveled internationally within the last 5 days. Transmission primarily occurs from ingestion of the virus. Photo courtesy of Dr. Serum testing has declined dramatically as the focus has shifted to testing tissue samples e.
