In countries where classical swine fever is endemic, vaccines may be used to protect animals. Serum porxinos has declined dramatically as the focus has shifted to testing tissue samples e. In a protein-rich environment, the virus is quite stable and can survive in refrigerated meat for months and frozen meat for years.

Some visitors are essential to the continued operation of the farm. 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. Hemorrhages can also occur in the skin. Cuarentena Sacrificio While CSF has been eradicated from many countries, re-introduction is always a possibility.

Actions needed will be directed by these animal health authorities. 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.

Fiebre Porcina Clásica

Additional differentials include African swine fever, hemolytic disease of the newborn, thrombocytopenic purpura, anticoagulant e.

This may entail complete herd slaughter combined with area restrictions on pig movements, or vaccination depending enfermexad local disease control regulations. Chronic disease symptoms include fever, anorexia, stunted growth, and alopecia; these symptoms may wax and wane for months.

Similar re-introductions of the disease have ocurred in the United Kingdomand other European countries Clinical signs of CSF resemble other common swine diseases and are clinically indistinguishable from those of African swine fever. The disease has been reported in parts of Mexico. Hemorrhages in the skin.

Additionally, we will talk about how it is transmitted, the species it affects, the clinical signs and necropsy findings, as well as the diagnosis and treatment of the disease. Necrotic foci are common in the tonsils, sometimes with pustules and severe congestion. Chronic infections are almost always fatal.

The incubation period ranges from 2 to 14 days. Sobre el proyecto SlidePlayer Condiciones de uso. Aerosol spread can occur in confined spaces; however the virus does not travel long distances in the air. Several days after the first symptoms appear, the abdomen, inner thighs and ears may become cyanotic purplish discoloration.

Sources of virus include blood and all tissues, secretions and excretion saliva, urine, feces, semen of sick and dead animals. Congenital infections with the pestiviruses that cause bovine virus diarrhea or border disease can resemble classical swine fever. Farm personnel should be familiar with signs to look for and who to contact when signs are noted.

Younger animals often have higher mortality rates than adult pigs. The clinical signs of CSF vary with the strain of the virus and the susceptibility of the pigs. Transmission primarily occurs from ingestion of the virus. Aujfszky mucosa porcinod reddened and contains multiple discrete “button” ulcers surrounded by zones of hemorrhage.

In congenitally infected piglets, common lesions include cerebellar hypoplasia, thymic atrophy, ascites, and deformities of the head and legs. As an example, inan outbreak of CSF in the Netherlands spread to more than herds in the country.

Humans are not susceptible to CSF infection. CSF can be distinguished by detecting the virus or its antigens in whole blood or tissue samples. CSF surveillance most commonly uses rRT-PCR real time reverse transcriptase polymerase chain reaction testing on tonsils and nasal swabs.

Porcine reproductive and respiratory syndrome and porcine circovirus associated diseases especially porcine dermatitis nephritis syndrome should also be considered. Passive reporting is conducted by private practitioners or producers, diagnosticians, slaughter plant inspectors of suspicious cases with clinical signs similar to a foreign animal disease such as CSF.

Producers will only receive indemnity for animals destroyed under the order of animal health officials. 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. No treatment should be attempted for pigs suspected with CSF. 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.

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 herd level. 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. There are numerous disseminated cortical petechiae “turkey egg kidney”.

The December CSF surveillance plan provides the rationale for this transition. Infected pigs are the only reservoir of virus. It is rapidly inactivated by pH 3 or less or pH greater than The definitive test for differentiation is the comparative neutralization test. The age and immune status of the animals also affects the disease outcome. Los productores de cerdos y el personal de campo deben conocer los peligros de la PPA y ser capaces de detectar la enfermedad Contar con puntos.
