Serological Investigation Of Infection And Influencing Factors Of Toxoplasma Gondii In Dogs And Cats In Shenyang Regions

Toxoplasma gondii(T.gondii)is a protozoan that can infect animal cells and parasitize in cells.It is widely distributed in the world.T.gondii infection can lead to toxoplasmosis,which is a common zoonotic parasitic disease.As two common companion animals,dogs and cats are closely related to humans.To learn about information on the epidemiology of T.gondii would be contribute to prevent and control the transmission of T.gondii among animals and humans.In this study,T.gondii Ig G antibody ELISA method was used to detect T.gondii antibodies in dogs and cats sera collected from June 2017 to October 2018 in Shenyang.The results showed that the positive rate of serum T.gondii antibody was 27.75% in domestic pet dogs,20.47% in domestic pet cats and 43.15% in stray cats.The positive rate of T.gondii serum antibody in domestic pet dogs was significantly higher than that in domestic cats(P <0.05),and that in stray cats was significantly higher than that in domestic dogs and cats(P <0.05).There was no significant difference in the positive rate of serum antibodies between domestic dogs and cats(P > 0.05).The positive rate of serum T.gondii antibody in domestic dogs and cats increased with age.The positive rate of T.gondii in domestic dogs and cats may be correlated with seasonal(monthly)changes.The infection rate of T.gondii in winter is lower than that in summer.There was no significant difference in the positive rate of serum antibodies between domestic dogs and cats in different breeds and regions,indicating that the breed and region of dogs and cats would not significantly affect toxoplasma infection.
