Abstract
Aim: The aim of this study was to study the interaction of intracellular pathogens of tick-borne encephalitis (TBE) and salmonella in Hyalomma asiaticum tick body during the bloodsucking of imago and nymphs on laboratory animals with viremia and bacteremia. With a simultaneous infection from H. asiaticum ticks by two intracellular pathogens (CE and salmonella virus), the virus titer decreases after 30–40 days, and then, the ticks die. Materials and Methods: The study was conducted on the ticks of a laboratory line, free from pathogenic flora. Tick encephalitis virus was used to infect ticks with the “Sofin” strain and the bacterial culture Salmonella typhimurium LT-2. Results:During an infection of nymphs, H. asiaticum virus persisted in their body for the entire observed period, both at the infection of nymphs with a mixed infection and at the infection with TBE virus. Salmonella persisted in the body of sexually mature H. asiaticum ticks with a mixed infection up to 12 days. Conclusions: With a mixed infection of ticks by two infection pathogens at the same time (TBE and salmonella virus), the inhibition of both TBE and salmonella virus growth and development takes place.
