Geohelminths eggs contamination of sandpits in Vladivostok, Russia

Objective: To detect nematode eggs in sandpits in urban area in Vladivostok. Methods: Totally 60 samples were collected from five districts. Sand samples were analyzed using combined flotation-sedimentation method. In result, 18 sand samples were positive for at one or two parasites species. Results: Overall, only 3 genera of helminths were recovered. Most samples were positive for Toxocara spp. eggs. Toxocara spp. eggs were found in each district. More samples with Toxocara spp. eggs were found in Pervomaiskii district. Ascaris spp. eggs were also appeared in each district, however Ascaris eggs rate of contamination was less than rate of Toxocara spp. contamination. Toxascaris leonina eggs were the less frequent species in sandpits, it was found only in Sovetskii and Pervomaiskii districts. Ascaris eggs rate of contamination was less than rate of Toxocara spp. contamination. Toxascaris leonina eggs were the less frequent species in sandpits, it was found only in two districts. No correlation between districts and helmiths eggs present in soil samples was found(P>0.05). Conclusions: Considering the high sand contamination with parasite infective elements of both human and animal origin, measures to improve environmental and sanitary conditions are indicated, as well as promoting the concept of responsible pet ownership.

Public places contamination in Tirana from dogs intestinal geohelminths

Objective:To assess the prevalence of infestation of stray dogs that attend public areas of Tirana by geohelminths zoonotic:Toxocara canis(T.canis),Ancylostomatids and Trichuris spp.,and indirectly to assess the level of environment contamination by invasive exogenous stages of these parasites.Methods:A total of 240 fecal samples was collected from stray dogs in public three urban areas of Tirana.These samples were analyzed by using the centrifugation-flotation technique.Results:Result showed that 54.58%of the dogs were infested from T.canis,Ancylostomatids(Ancylostoma spp.and Uncinaria spp.)and Trichuris spp.Those infested dogs from Ancylostomatids were 37(15.41%),from T.canis were 47(19.58%)and from Trichuris sp.were 47(19.58%).Conclusions:Tirana public places are contaminated by exogenous stages of invasive intestinal dog’s geohelminths all through the year.But the contamination level is higher during the spring and autumn and the parks with trees and grass are more polluted than the bare areas.So these environments have become a permanent risk factor of infection from parasitic zoonoses for the humans and animals that frequent those places.It is the duty of local authorities who takes care of legislation compilation,to prevent the public areas to become fecalized from dogs and to implement a plan with different actions to minimize the number of stray dogs.
