Seroprevalence of Neospora caninum and Toxoplasma gondii in exotic ruminants and camelids in the Czech Republic

Abstract

Neospora caninum and Toxoplasma gondii are the protozoan parasites with definitive hosts from order Carnivora. Due to vertical transmission, both parasites can cause abortions and neonatal mortality that lead to significant productive and economic losses in the domestic ruminants. The aim of this study was to describe N. caninum and T. gondii seroprevalence in the group of frequently farmed captive exotic ruminants (n = 184) including Bovidae (barbary sheep, bezoar goat, common eland, American bison, water buffalo, and yak) and Camelidae (bactrian camel, guanaco, llama, and alpaca). Antibodies were tested by indirect fluorescent antibody test (IFAT) and enzyme-linked immunosorbent assay (ELISA). Higher prevalence of T. gondii antibodies (31% in IFAT and 52% in ELISA) was detected compared to N. caninum (24% in IFAT and 17% in cELISA). Mixed infection was found in 18 (10%) and 22 (12%) animals by IFAT and ELISA, respectively. Higher seroprevalence of both N. caninum and T. gondii was found in Camelidae compared to Bovidae. To author knowledge, this is the first detection of T. gondii and N. caninum antibodies in common elands and bezoar goats.
