Identity of Microfilariae Circulating in Dogs from Western and South-Western Romania in the Last Decade

Dirofilaria infections in dogs are recognized as widespread mosquito-borne diseases with zoonotic potential, that are caused by the filarioid nematode (Onchocercidae) species Dirofilaria immitis and Dirofilaria repens. The l...

The long-term survey conducted in western and south-western Romania was undertaken in order to provide valuable data on the occurrence of <i>Dirofilaria</i> infections in dogs. Blood samples from 1088 dogs, originating from 73 localities of 11 western and south-western counties in Romania, were collected and examined using the modified Knott test. Subsequently, all of the microscopically positive samples were subjected to molecular analysis for confirmation. Altogether, the data obtained showed the percentage of dogs with circulating microfilariae to be 21.42% (233/1088) of dogs tested in the investigated region. The identified species, in cases of monoinfections, were <i>D. immitis</i>, <i>D. repens</i>, and <i>Acanthocheilonema reconditum</i> in 106 (9.74%) samples, 102 (9.38%) samples, and 1 (0.09%) sample, respectively. Twenty-four (2.21%) samples were simultaneously positive for <i>D. immitis</i> and <i>D. repens</i>. There was no association (<i>p</i> > 0.05) between infection status and breed; however, sex and lifestyle were positively associated (<i>p</i> < 0.05) with the percentage of dogs with circulating microfilariae and might be regarded as risk factors for infection. The results of the present investigation indicate potential zoonotic risks for humans living in the screened area and support the imperative to increase awareness among both veterinarians and physicians, regarding the continuous spread of these zoonotic filariae.Simona GiubegaMirela ImreMarius Stelian IlieKálmán ImreIasmina LucaTiana FloreaGheorghe DărăbușSorin MorariuMDPI AGarticle<i>Dirofilaria</i><i>Acanthocheilonema</i>dogsdirofilariosisRomaniaMedicineRENPathogens, Vol 10, Iss 1400, p 1400 (2021)
