This study aimed to survey the current distribution of Toxoplasma gondii (T. gondii) seropositivity within the cat population in Budapest area. Therefore, blood samples of 123 cats aged 0.5-18 years were collected. The measurements were performed by the commercial ID Screen(R) Toxoplasmosis Indirect Multi-species ELISA kit. The results indicate an overall 31.7% of seropositivity, which was significantly increasing with age. A correlation was also detected between the outdoor lifestyle and T. gondii infection. A significantly higher proportion of cats living outdoors were seropositive (38.8%) compared to those living indoor (18.6%) (P 5 0.022). Finally, our study indicates a lower T. gondii seropositivity rate in cats compared to previous studies from Hungary, as well as from other European regions.  Kulcsszavak: Toxoplasma gondii, cat, seroprevalence
