Biography
Hovhannes Naghashyan from 2009 to present is Head of
Department of Epizootology and Parasitology of National
agrarian University of 2002 was Awarded the
title of Professor of veterinary medicine.1994 - Awarded the
degree of doctor of veterinary Sciences.1982 - Institute of
farmacology and toxicology (Ukraine) Awarded the degree of
doctor of biology.1968 – 1974 - Veterinary faculty of Yerevan
Zooveterinary. 2001-2009 – Professor of Department of
Epizootology and Parasitology of State agrarian University of
Armenia.
The aimof our workwas to study the soil cover in public places of Yerevan for the
contamination of eggs and spores of parasites which are dangerous for health
of animals and people and to give a veterinary and sanitary assessment. This
full-scale sanitary research of the soil in Yerevan was first held us in 2015-2016.
The study was subjected to soil samples taken from 28 urban parks and squares
belonging to 12 administrative districts. Studies of soil samples was carried out
at research center for soil science, agro chemistry and melioration named after
H Petrosyan, as well as in the laboratory of parasitic studies of the Department
of Epizootology and Parasitology of the National Agrarian University of Armenia.
The same samples were examined in a comparative manner by two methods:
Romanenko and the method, used to detect helminth eggs, ticks and intestinal
protozoa spores in soil. As a result of studies conducted during 2015-2016,
eggs of the following helminths were found in soil samples, taken from different
administrative districts of Yerevan: nematodes: Toxocara canis, Toxascaris leonina,
Trichochephalus vulpis, Uncinaria stenocephala, Ancylostoma caninum; cestodes:
Dipilidium caninum, Taenia Hydatigena, Diphylobotrium latum; as well as spores of
parasitic protozoa Neospora caninum, Cystoisospora Canis. Eggs of nematodes of
species Ancylostoma duodenale, Ascarls lumbricoldes, Trichocephalus trichiurus,
and of the simplest spores Entamoeba histolytica and Balantidium coli were found
from pathogens inherent only to humans. It should be noted that the conditions
necessary for the development of cestodes Diphylibothrium latum in our country
are absent. Soil contamination of 12 administrative districts of Yerevan with eggs
and spores of parasites is caused by the increase in the number of domestic
animals in the city, the lack of planned preventive measures in the city and the
corresponding propaganda among the urban population.
