PastQ Flashcards
Rabid animal
Means an animal in which unquestionable laboratory tests have confirmed rabies
CLASSICAL SWINE FEVER
Surveillance zone
- A radius of at least 10 km
- Census of all holdings
- Prohibition of any movement or transport of pigs
- Cleaning and disinfection
- Removal of pigs from a holding situated in a surveillance or protection zone must be authorized by the veterinary authory
CLASSICAL SWINE FEVER
Repopulation of a holding affected by the disease
- Minimum 30 days after cleaning and disinfection
- Open-air holdings: full repopulation may take place only if no sentinel pigs has developed antibodies against the virus
AFRICAN SWINE FEVER Surveillance zone (restricted zone II)
- A radius of at least 10 km
- Lifting restrictions: serological survey
- Min 30 days
AFRICAN SWINE FEVER
Restocking
• In the case of holdings where the occurrence of disease has been linked to vectors, restocking shall not take place for at least 6 years unless:
- Specific operations to eliminate the vector from the premises and places where the pigs are kept or can come into contact with the vector have been successfully carried out under official supervision,
OR - It has been possible to show that
the presens of the vector no longer represents a significant risk of African swine fever being transmitted
AUJESZKY DISEASE
Control of free status: regular tests
• Large scale holding
o All boars: every 6 months
o Sows:20-50%every6months
o Representative sample of fattening pigs
TESCHOVIRUS
Large scale holding
- All diseased and suspected of being diseased pig: killed on the spot
- Suspected of being contaminated: observation for 40 days, if slaughtered: heat treatment
ANTHRAX
Infected areas
- Pasture or other area where anthrax was confirmed or which was the origin of infection (eg. water, feedstuff source)
- Village, farm, holding where anthrax was confirmed
- Burying ground or pound
• Measures:
- Fence
- No grazing, feed stuff production in the area
- Only vaccinated animals may be kept there
- For minimum 25 years!!
ANTHRAX
Public measures
- Notification to state medical service
- Informing the keeper, owner
- Personal disinfection
- Protective gloves, gloves and footwear
- Keeping the floor wet, prevention of dust
FOOT AND MOUTH DISEASE
Sampling
- The preferred tissue for diagnosis is epithelium from an unruptured or freshly ruptured vesicle
- Where this is not possible, saliva and blood and/or esophageal-pharyngeal fluid samples taken by probang cup in ruminants or throat swabs from swine provide an alternative source of virus
- Myocardial tissue or blood can be submitted from fatal cases, but vesicles are again preferable if present
- It is vital that samples from suspected cases are transported under secure special conditions and according to the international regulations. They should only be dispatched to authorized laboratories
BOVINE BRUCELLOSIS
Public health measures
- Notification to state medical service
- Informing the keeper, owner (pregnancy!)
- Personal disinfection
- Protective clothes, gloves and footwear
- Control of products
CONTAGIOUS BOVINE PLEUROPNEUMONIA (CBPP)
Country free from infection without intermediate steps
• Continuously free from CBPP for at least 10 years
• No vaccination for at least 10 years
• No clinical or pathological evidence for at least 10 years
• Adequate disease surveillance and reporting system
• Use of diagnostic procedures capable of differentiating Mycoplasma mycoides from
other bovine Mycoplasma infections
CONTAGIOUS BOVINE PLEUROPNEUMONIA (CBPP)
Re-establishing infection free status
• 2 years from the date of the last case
• Demonstration that the outbreak did not represent endemic infection and that the
disease has been eradicated by the actions taken
BLUETONGUE
Measures in the protection zone
- The identification of all holdings with animals inside the zone
- The implementation by the competent authority of an epidemio-surveillance programme based on the monitoring of sentinel groups of bovine animals (or, in their absence, of other species of ruminant) and vector populations
- A ban on animals leaving the zone. However, exemptions from the exit ban may be decided on in particular for animals situated in part of the zone where there is a proven absence of viral circulation or of vectors
- Vaccination of animals bluetongue and their identification in the protection zone may be decided
GLANDERS
Definition of diseased animals
- Typical clinical signs
- Non-typical clinical signs but immunodiagnostic test “+”
- No clinical signs but repeated immunodiagnostic test “+”
GLANDERS
Public health measures
- Notification to the public health service
- Informing the keepers
- Protective cloth, personal disinfection
- No treatment of infected animals
- SD: treatment only by veterinarian
AFRICAN HORSE SICKNESS
Protection zone

- A minimum radios of 100 km
- Taking into account of epidemiological, geographical, climatic conditions
- Informing the public about restrictions
- Disinfection
- Visit of all holding keeping equidae, samples
- Movement of horses: only for emergency slaughter
