PQ i state Flashcards
Rabid animal
Means an animal in which unquestionable laboratory tests have confirmed rabies
CSF - 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 is subject of authorisation by the veterinary authory
CSF - Repopulation of a holding affected by the disease
Minimum 30 days after the completion of the cleaning and disinfection operations
Open-air holdings: full repopulation may take place only if none of the sentinel pigs has developed antibodies against the virus
ASF - Surveillance zone (restricted zone II)
A radius of at least 10 km
Lifting restrictions: serological survey
Min 30 days
ASF - 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 to be 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It has been possible to show that the persistence of the vector no longer represents a significant risk of African swine fever being transmitted
Aujesky - contorll of free status: regular tests
Large scale holding
All boars: every 6 months
Sows: 20-50% every 6 months
Representative sample of fattening pigs
Tescho - 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, feedstuff
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
FMD - 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 - 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
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 “+”
