1-10 Flashcards
- definition of animals suspected of being infected with anthrax
in contact within 20 days to an animal that died of, diseased in or suspicious to anthrax, before the confirmation
ate the same feed and water as an confirmed, diseased or suspicious animal
grazed on a pasture infected with anthrax without vaccination (min 2 weeks and max 6 months before)
- Definition of animals diseased with anthrax
Typical clinical signs
characteristic lesions in the organs
laboratory findings
- Official measures in case of animals diseased with anthrax
Separation of:
- diseased animals and those suspected of being diseases
- animals suspected of bein infected
- other susceptible animals
Diseased and suspected diseased animals
- immediate obligatory treatment
- change of feedstuffs, drinking water, no grazing
- Official measures in case of animals suspected of being infected with anthrax
vaccination, 14 days observation period
- cattle + horse: taking te temperature regularly
- sheep + gat + pig: daily observation
- in case of fever or clinical signs: treatment
- rules of taking samples in case of FMD suspicion
1 gr of tissue taken from a vesicle or freshly erupted vesicle
- epithelium samples are placed in a transport medium wit 7.2-7.4 in pH
- sample kept at 4 degrees
- Probang cup is needed for taking oesophageal-pharyngeal fluid
- Use of vaccination in case of confirmation of FMD
- trade of vaccinated animals is prohibited
- vaccinated animals from tested herds may be moved within member state
- system of traceability excludes them from community trade
Emergency vaccination
- classification of herds
- animals are clearly identified and registered, must not be moved
- specific measures in the vaccination zone on movement of other products and animals
- clinical and serological survey
Protective vaccination
- regionalization of the vaccination zone
- second surveillance zone: 10km
Suppressive vaccination
- immediate stamping out strategy
- ensure minimum spread of the virus during disposal of infected animals
carried out only within the protection zone and on clearly identified holdings
- Rules of recovery of FMD disease free status if no vaccination has been used
The control and eradication measures laid down for the protection and surveillance zones have been effective and may be lifted and
at least 3 months have elapsed after the last recorded outbreak
- Definition of officially brucellosis free bovine herd
no clinical signs - for min 12 months
no vaccination - for min 3 years
all animals over 12 months: two serological tests on 6-12 months interval
animals introduced are from officially free herds or are tested within 30 days
regular testing (every year)
general masures
- isolation of the holding
- record of comp. laboratory examinaitons
- separate calving
- control of movement of visitiors, vehicles, control of dogs and cats of the holding
- definition of positive single intradermal tuberculin test
Positive reaction:
if clinical signs are observed or there is an increase of 4 mm or more in the thickness of the fold of skin at the injection site
- definition of negative single intradermal tuberculin test
Negative reaction:
if only limited swelling is observed, with an increase of not more than 2 mm in the thickness of the fold of skin without clinical signs such as diffuse or extensive oedema, exudation, necrosis, pain or inflammation of the lymphatic ducts in that region or of the lymph nodes.
