To make this website work, we log user data and share it with processors. 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.

Fiebre Porcina Clásica

Only a few animals in the herd may show signs of illness and these signs can resemble other swine diseases. Similar re-introductions of the disease have ocurred in the United Kingdomand other European countries Aerosol spread can occur in confined spaces; however aijeszky virus does not travel long distances in the air. This is a less common route of transmission as is transfer by insect vectors.

Reproductive symptoms may also be seen with any level of virulence. Al secado A la luz ultravioleta pH menor a 3 o mayor a 11 Inactivado a altas temperaturas oF durante 30 minutos; oF durante 1 minuto CSFV is moderately fragile in the environment.

Some visitors are essential to the continued operation of the farm. 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. Since the CSFV is stable in the tissues of infected animals, feeding these materials may transfer the virus to susceptible swine.


Transfer of the virus can also occur through direct contact of pigs with infected animals; wn can occur through the mucous membranes, conjunctiva, and skin abrasions. They should be cleaned after each use. Subacute disease usually has lower case-fatality rates compared to acute cases; mild cases of illness have lower mortality rates.

Los botones se encuentran debajo. 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. Confirmed cases and in-contact animals should be slaughtered, and measures taken to protect other pigs in the area.

The green areas indicate areas where CSF has never been reported. Only one CSFV serotype has been fond, but there is minor antigenic variability between strains.

We will also talk about the economic impact the disease has had in the past and could have in the future. 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.

Additionally, boots should be disinfected and clean clothing should always be worn when coming in contact with pigs. The mucosa is reddened and contains multiple discrete “button” ulcers surrounded by zones of hemorrhage. Official herd quarantines may be imposed in efforts to control the spread of the disease. With acute infection, the most common lesion is hemorrhage, often seen on serosal and mucosal surfaces particularly the kidney, urinary bladder, epicardium, larynx, intestines, spleen and lungs.

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. 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.


The cortex contains multiple petechiae and pale infarcts surrounded by hemorrhage. Sobre el proyecto SlidePlayer Condiciones de uso. Other previously described clinical signs may be noted.

CSF surveillance most commonly uses rRT-PCR real time reverse transcriptase polymerase chain reaction testing on tonsils and nasal swabs.

The age and immune status of the animals also affects the disease outcome. History of the pigs or traffic onto the farm is also important. Hemorrhages can also occur in the skin.

Some infections of CSF can by asymptomatic; these animals may serve as carriers for further dissemination of the disease. The virus is stable at pH Sodium hypochlorite and phenolic compounds are effective disinfectants. The virus can range from high to low virulence, resulting in acute, subacute, chronic and persistent forms of the disease in infected swine.

As an example, inan outbreak of CSF in the Netherlands spread to more than herds in the country. Clinical signs of CSF resemble other common swine diseases and are clinically indistinguishable from those of African swine fever. Chronic infections are almost always fatal. The figure shows a fast replicating, highly virulent oval and large plaque virus, and a slow replicating, lower enfermevad small and round plaques virus replicating on a cell plaque.
