Abstract
Cercetările parazitologice s-au realizat în zona de Centru–Sud a Republicii Moldova în scopul stabilirii extensivităţii şi intensivităţii infestației cu ectoparaziți la palmipedele domestice (rațe). Au fost investigate parazitologic 105 rațe (Anas platyrhynchos domesticus ) în vârstă de 1-2 ani, la care s-a stabilit infestarea cu 6 specii de malofagi (Trinoton querquedulae, Anatoecus icterodes, Anatoecus dentatus, Anaticola crassicornis, Anaticola anserinum, Menopon obscurum) și o specie de acarieni gamazizi (Dermanyssus gallinae). La rațele infestate cu ectoparaziţi s-a stabilit reducerea numărului de eritrocite cu 34,0%, a cantităţii de hemoglobină - cu 27,3% şi a trombocitelor - cu 17,7%, comparativ cu valorile de referință, iar numărul leucocitelor era mai sporit cu 10,4%, nivelul de limfocite, diminuat cu 36,2%. S-a stabilit o superioritate a monocitelor, atingând cota de 32,6%. Indicile VSH (viteza de sedimentare a hematiilor) a fost sporit cu 35,9%, iar numărul de eozinofile majorat cu 31,1 %, comparativ cu valorile de referință.
Parasitological research was conducted in the Central-Southern area of the Republic of Moldova in order to establish the extent and intensity of ectoparasite infestation in domestic palmipeds (ducks). 105 ducks (Anas platyrhynchos domesticus) aged 1-2 years were investigated parasitologically, in which infestation with 6 species of malophagous mites (Trinoton querquedulae, Anatoecus icterodes, Anatoecus dentatus, Anaticola crassicornis, Anaticola anserinum, Menopon obscurum) and one species of gamasid mites (Dermanyssus gallinae) was established. In ducks infested with ectoparasites, a reduction in the number of erythrocytes by 34.0%, in the amount of hemoglobin - by 27.3% and in platelets - by 17.7%, compared to reference values, and the number of leukocytes were increased by 10.4%, the level of lymphocytes, decreased by 36.2%. A superiority of monocytes were established, reaching the level of 32.6%. ESR (erythrocyte sedimentation rate) indices were increased by 35.9%, and the number of eosinophils increased by 31.1%, compared to reference values.
