Dakhno Y. Dirofilariasis of dogs (spreading, diagnostics, treatment).

The author summarizes findings of spreading, diagnostics, treatment of dirofilariasis in dogs in central and northern parts of Ukraine. The results of the studies found seasonal and age dynamics dirofilariasis dogs depending on sex, breed and household goods. Hematological study (morphological and biochemical) parameters in infested with dirofilaria dogs. In laboratory diagnostics microfilariae wich were painted with gentian violet, became pink. This prolongs the duration of staining microscopic studies up to 10 days. A method for the study of mosquitoes, which included their catching and storage in oxypropionic acid (75% lactic acid) for 24 hours, enabling the study of dirofilaria larvae under a microscope. Found that dirofilaria larvae in Poltava and Sumy regions affected with two mosquito species – Aedes and Culex. The high sensitivity of enzyme-linked immunosorbent assay fractionated somatic antigen of mature D. repens. The sensitivity of the test was 76,5 % and specificity – 80,6 %. Study of helminthologycal autopsy of dogs, extensivity of invasion was 61,9%. Found that D. repens male’s left spicules ends with kope like formation. This can be used as diagnostic features to consider when determining the worms to species. The effect of anthelmintic drugs brovermectin-granulate for the treatment, prevention and chemistryprevention dirofilariasis in dogs was studied.
