Abstract
Bovine Tuberculosis Slaughter Surveillance in Albania, Importance of Its Traceback Investigation Based on Singel Cervical Comparative Skin Test
Highlights
Bovine tuberculosis due by Mycobacterium bovis (M. bovis) is a zoonotic disease, spread worldwide, affects the widest range of mammals, including humans [1,2,3]
M. bovis is slow growing bacteria, able to survive in the environment conditions, which interfere with pathogen isolation and in other hand contaminated environment, including manure may serve as source of infection [5]
We present results from a pilot study on usefulness of surveillance of Bovine tuberculosis (bTB) based on single intradermal comparative cervical tuberculin test (SICCT) by tracing back the farm origin of a calf infected by bTB
Summary
Bovine tuberculosis (bTB) due by Mycobacterium bovis (M. bovis) is a zoonotic disease, spread worldwide, affects the widest range of mammals, including humans [1,2,3]. M. bovis transmission occur in direct and indirect routes, and it is present in aerosol of infected animals, sputum, excretions, secretions and tissues. The inhalation is most common and efficient method of infection, where the infected dose ranges from 1-10 bacteria [5,6] Ingestion is another important method for transmission from infected animal to susceptible animal, but the infected doses is very high compare to the inhalation route. In pulmonary form, which is typically for relatively old animals infected by inhalation, while the extrapulmonary form is related with digestive route of infection and mesenterial lymph nodes often are involve. Transmission of disease between herds is most likely to occur by introducing infected animals to the free herds, while contaminated vehicles, visitors etc play role in speeding of bTB to the new herds. Applying strict animal movement control and biosecurity measures play important role in reducing the
