Horb K. Dog ctenocephalosis (spreading, diagnostics, and treatment)

New data concerning species composition of ctenocephalosis causative agents parasitizing on dogs in Poltava city were received. It has been determined that species composition of Ctenocephalides genus fleas is represented by two causative agents – Ctenocephalides felis Bouche, 1835 and Ctenocephalides canis Curtis, 1826. New data about the peculiarities of ctenocephalosis development in dog association invasions were obtained. It has been revealed that fleas of Ctenocephalides genus parasitize on dogs, mainly, together with causative agents of nematodoses, cestodoses, protozoases, and myioses (Рrevalence made 31.18 %, and the part of dogs infected with fleas – up to 63.03 %). Seasonal dynamics of dog ctenocephalosis is characterized by the peak of invasion in the summer period, when рrevalence made 63.04 %. It has been detected by the studies that changes in hematological indicators of dogs infected with Ctenocephalides spp. depends on the indices of infection intensity. For the first time in Ukraine, morphometric indices of imago fleas’ males and females of Ct. felis and Ct. canis species, isolated from domestic dogs, have been analyzed, which will allow to increase the effectiveness of species identification of these parasitic insects/ The method of making permanent preparations of Ctenocephalides genus fleas in toto was improved, proposed, and experimentally substantiated. It has been determined that the most effective insecticidal preparations in fighting dog ctenocephalosis, caused by parasitizing fleas of Ct. felis and Ct. canis species, are “Simparica” oral tablets and “Fipren” drops.
