Abstract

Introduction: Hard ticks are hematophagous ectoparasites, vectors of emerging zoonotic pathogens. Until 2011, there was evidence of infection/exposure to Borrelia burgdorferi in humans in Cuba, but the circulation of other agents is unknown. Aim: implement new diagnostic tools, explore infection/exposure of humans to tick-borne pathogens, their presence in vectors and level of knowledge in medical personnel.
Methods: Multiplex PCR to detect B. burgdorferi-Anaplasma spp.- Babesia spp., PCR for Borrelia spp., and artificial infection of ticks were implemented. Positivity to infection by B. burgdorferi (2011-2018) was described. Presence of antibodies against borrelias in blood donors from a low-exposure region, antibodies against other zoonotic agents in a population at risk, presence of these agents in ticks, as well as the level of knowledge about Lyme disease in doctors were explored.
Results: IPK capabilities for molecular detection of tick-borne pathogens were strengthened. New serological evidence of B. burgdorferi infection was found in patients with suspicion of Lyme disease. Absence of specific antibodies against B. burgdorferi was demonstrated in blood donors. Evidence of antibodies to Anaplasma phagocytophilum, Ehrlichia chaffeensis and Babesia microti were found. The presence of Anaplasma spp., Babesia spp., Rickettsia amblyommii and Coxiella burnetii was demonstrated in ticks. Insufficient knowledge about Lyme disease was found in medical personnel. Conclusions: these results alert the national public health authorities and medical personnel about the risk of infection in individuals exposed to tick bites.
