2024
Seyidov, M.
Listeriosis is a dangerous disease. Ixodid ticks are natural carriers of listeria. The aim of the work is to study listeriosis in sheep in the Nakhchivan Autonomous Republic and the role of ixodid ticks in their spread. In 2022, studies were conducted in the Sharur, Babek, and Julfa districts. Ticks were 2collected twice a year: in spring (April-May) and autumn (September-October). The pathogen can be transmitted from generation to generation through transovarial and metamorphic pathways. The causative agent of listeria is H. anatolicumand H. asiaticum and can persist in the body of ticks for up to 18 months, and female ticks are able to transmit listeria transovarially from one stage of development to another during their development. It has been established that young sheep aged 8-14 months are more susceptible to infection with listeriosis.
