Rezultati nadzora na bolest nodularni dermatitis koji se sprovodio u Republici Srbiji u 2020. godini i dalji planovi za 2021. godinu

Abstract

During 2020, a surveillance program for Nodular dermatitis (hereinafter: LSD) was implemented in the Republic of Serbia, the aim of which was to periodically visit randomly selected facilities where cattle are kept, conduct clinical surveillance and sampling for serological and virological tests of non-immune cattle. The purpose of the Program was to conduct surveillance to prove the absence of disease in previously affected areas and surveillance for early detection of ND disease (recurrence or reintroduction). A program has been established to detect any clinical cases of ND and to test samples with antigen or antibody detection tests and a system of passive clinical surveillance and early detection. The target population for active clinical and passive surveillance was the entire cattle population of the Republic of Serbia. Passive surveillance existed on the entire territory of the Republic of Serbia throughout the year, and in accordance with this plan, active surveillance was established through clinical and epidemiological investigation of each suspicious case. All suspected cases were substantiated by appropriate serological and virological laboratory tests and appropriate epizootiological research to confirm or rule out LSD disease. The target population for active serological surveillance was cattle that were not vaccinated against LSD, and in the case of calves from vaccinated cows, samples were taken only from calves older than 6 months. Active clinical and serological surveillance of ND was conducted in the risk period from August to November 2020. Active clinical and serological surveillance was conducted throughout the country where the whole country is divided into two zones: high risk zone, zone 1 where Belgrade districts, Borski, Branicevski, Jablanicki, Kolubara, Macvanski, Moravicki, Nisavski, Pirotski, Podunavski, Pomoravski, Pcinjski, Rasinski, Raski, Toplicki, Zajecarski, Zlatiborski and Sumadijski. These are regions that have previously been declared infected or where there was a risk of introducing ND from neighboring countries or where there was an increased risk of recurrence of infection; Low risk zone - zone 2: Južno-Banatski, Južno-Bački, Severno-Banatski, Severno-Bački, Srednje-Banatski, Sremski and Zapadno-Bački where risk was observed as a consequence of animal movement. No positive ND cases were reported during the implementation of this program.
