Seroprevalence of Toxoplasma gondii in domestic cats, dogs and rabbits from Poland

The seroprevalence of Toxoplasma gondii in domestic cats, dogs and rabbits was evaluated. Samples from cats and dogs were collected from five veterinary practices from various parts of Poland - Poznan (wielkopolskie voivodeship), Przemysl (podkarpackie voivodeship), Kluczbork (opolskie voivodeship), Lublin (lubelskie voivodeship) and Deblin (lubelskie voivodeship). Moreover, the samples from rabbits were collected in Poznan. In total, serum samples from 193 cats, 204 dogs and 71 rabbits were randomly selected and tested for specific antibodies against T. gondii using a commercial ELISA test. Pathogen seroprevalence among cats and dogs was calculated at a 95% confidence interval (CI) for each sex and age category (up to 12 months, 1-3 years, 4-7 years and over 8 years) and compared with a chi-squared test. The highest seroprevalence of T. gondii was noted in cats - 49.74% (96/193; 95% CI: 42.76-56.73). In dogs, it reached 28.92% (59/204; 95% CI: 23.13-35.49). Only 1 rabbit (3-year-old male) was seropositive, and the seroprevalence in rabbits was 1.41% (1/71; 95% CI: 0.25-7.56). A statistically significant correlation between seropositivity and age (p < 0.05) was observed in cats and dogs. No statistically significant difference in seroprevalence concerning gender or location was found in cats and dogs. Our findings indicate that cat and dog serum samples had a high frequency of anti-T. gondii antibodies, while rabbit serum samples had low frequency and that these species are exposed to T. gondii in Poland and develop humoral response due to infection.

Automated summary

The seroprevalence of Toxoplasma gondii in domestic cats, dogs, and rabbits in Poland was investigated. The study found that cats had the highest seroprevalence rate (49.74%), followed by dogs (28.92%) and rabbits (1.41%). There was a significant correlation between seropositivity and age in cats and dogs, but no significant difference based on gender or location. These findings suggest that cats and dogs in Poland are frequently exposed to T. gondii and develop an immune response.
