The true story of Dirofilaria in the Czech Republic

Original language description

The first autochthonous infection of Dirofilaria repens and Dirofilaria immitis in the Czech Republic were reported in 2006 [1] using several diagnostic methods for detections of these parasites. Since then, Dirofilaria infection was repeatedly reported in dogs [2] and, recently, D. repens was detected also in mosquitoes [3] and in humans [4]. The presence of D. immitis in the Czech Republic was established only on detection of antigen using the commercially available test. In past 10 years, detection of D. immitis microfilariae, PCR detection or clinical case of canine dirofilariosis caused by D. immitis were not reported from the Czech Republic. The aim of presented survey was to confirm or exclude the autochthonous infection of D. immitis in dogs from the Czech Republic and to determine the extent of endemic distribution of D. repens within the Czech Republic. A total number of 392 blood samples from dogs were examined using the modified Knott test, IDEXX SNAP? 4Dx? test and PCR amplifying the fragment of COI gene of filarial nematodes [5]. Only D. repens was detected by Knott test and /or by PCR with prevalence 6.4% (25/392). Six out of 25 positively diagnosed dogs had no travel history outside the Czech Republic, so the autochthonous infection was proven in 3.4% animals. Almost all positive dogs had originated from Southern Moravia region except a single one, which was from Zlín region, 100 km north of other positive localities. D. repens prevalence demonstrated in our sample set is lower than previously published (9? 24%), however, distribution of positive animals corresponds well with published presence of D. repens positive mosquitoes and with occurrence of cases of autochthonous human dirofilariosis from the same region. Our study confirmed the endemic occurrence of D. repens in the region of Southern Moravia in the Czech Republic. Importantly, no D. immitis was detected.
