Abstract

POLIPARASITIC FAUNA OF WILD MAMMALS INHABITING NATURAL RESERVATION “CODRII” IN THE REPUBLIC OF MOLDOVA

The study on parasitic fauna in wild mammals from natural reservation “Codrii” in Republic of Moldova has revealed the high level of their infestation with fascicles, dicrocelium, strongiles and protista. The red deer (Cervus elaphus Linaeus, 1758) have been infested with Dicrocoelium lanceolatum (12,8%), Fasciola hepatica (9,5%), strongiles larvae (88,0%) and ovocysts of Eimeria spp. (28,2%); the Japanese deer (Cervus nippon Temminsk, 1838) has been infested with D. lanceolatum (14,9%), F. hepatica (10,2%), strongiles larvae (79,8%) and ovocysts of Eimeria spp. (22,4%); roedeer (Capreolus capreolus Linaeus, 1758) – with D. lanceolatum (20,1%), F. hepatica (3,2%), strongiles larvae (89,4%) and ovocysts of Eimeria spp. (38,1%). The wild boar revealed 3,6% level of infestation with Dicrocoelium lanceolatum, larvae of Strongyloides ransomi in 72,3% of cases, Metastrongylus elongatus (87,5%), and Eimeria spp. (46,3%). The jackrabbit revealed 28,2% infestation level with D. lanceolatum and 59,4% level of infestation with Strongyloides papillosus. The high level of parasitic infestation of the wild animals again demonstrates that they play an important role in maintaining the epizootic chain of these diseases and also have crucial role in infesting humans and domestic animals. Therefore it is of paramount importance that parasitic diseases in wild animals are monitored on annual basis that allows to determin their evolution, emergence of new parasitic agents and elaborating new combating measures for such.
