Abstract：To understand the status of Toxoplasma gondii infection in dogs and cats in Minhang District, Shanghai in 2024, a total of 328 dog serum samples and 149 cat serum samples were tested for Toxoplasma gondii antibodies using the enzyme-linked immunosorbent assay (ELISA). The results showed that the average positive rate of Toxoplasma gondii antibodies was 19.50%, with a positive rate of 22.87% in dogs and 12.08% in cats, showing a significant difference (P < 0.05). Among different sources of dogs, rural dogs had the highest positive rate at 35.87%, which was significantly higher than that of urban dogs (19.90%), experimental dogs (0%), and stray dogs (6.67%) (P < 0.05).
