Abstract：
BACKGROUND: During the last decades, filarial infections caused by Dirofilaria spp. have spread rapidly within dog populations of several European countries. Increasing scientific interest in filariasis, and the availability of new diagnostic tools, has led to improved knowledge of the biology, morphology, and epidemiology of different species of filarial worms. However, data are still scarce for a number of countries, including the Republic of Moldova. Thus, we assessed the epidemiological status of canine filariasis in the Republic of Moldova to address part of this knowledge gap.
METHODS: A total of 120 blood samples were collected between June 2018 and July 2019 from dogs originating from the cities of Cahul and Chişinău. The samples were examined microscopically, and multiplex polymerase chain reaction was performed to evaluate filarioid species diversity.
RESULTS: Microscopic examination revealed that 12 dogs (10.0%) were positive for circulating microfilariae. The molecular test showed that one dog was positive for Acanthocheilonema reconditum (0.8%), one for Dirofilaria immitis (0.8%), six for Dirofilaria repens (5.0%), and four (3.3%) harboured a co-infection with D. immitis and D. repens. Prevalence was significantly higher in dogs aged ≥ 2 years.
CONCLUSIONS: The epidemiological survey presented here for the Republic of Moldova confirmed the presence D. immitis, D. repens and A. reconditum in dogs that had not received any heartworm preventive.
