There are not any records on the detection of Toxoplasma gondii and Neospora caninum in tissues of wild birds in the African continent. The aim of the study was to investigate the occurrence of DNA from these protozoan parasites in brain tissue samples collected in years 2014-2015 from 110 wild and domestic birds of 15 orders. Birds came mainly from the province of Limpopo (n=103); the other seven birds came from other five provinces of South Africa. Parasite DNAs were detected by PCR in animal brains. While all samples were negative for N. caninum, T. gondii DNA was detected in three (2.7%) birds: a Red-eyed Dove (Streptopelia semitorquata), a Laughing Dove (S. senegalensis) and a Southern-Yellow-billed Hornbill (Tockus leucomelas), all from Limpopo province. Positive samples were selected for genotyping by a 15 microsatellite markers method in a single multiplex PCR assay. Only the sample from the Red-eyed Dove was successfully genotyped and characterized as type II. This is the first detection of T. gondii in tissue of native African wild birds and the first study focusing on N. caninum in birds from South Africa.

Relatively little is known about protozoan parasites in African animals. Here we investigated the occurrence of protozoan parasites in mammals from South Africa. Oocysts of protozoan parasites were detected in 13 of 56 (23%) fecal samples using conventional microscopic examination methods. Cryptosporidium spp. and Cystoisospora spp. were detected in eight (14%) and five (9%) samples, respectively. Mixed parasitic infection of Cryptosporidium spp. and Cystoisospora spp. was recorded in banded mongoose ( Mungos mungo). Cryptosporidium spp. was detected for the first time in cheetah ( Acinonyx jubatus), spotted hyena ( Crocuta crocuta), and African polecat ( Ictonyx striatus). Antibodies to Toxoplasma gondii and Neospora caninum were not detected by enzyme-linked immunosorbent assay in any of 32 sera tested. We detected T. gondii by PCR in tissues of five of 243 (2%) animals: domestic dog ( Canis lupus familiaris), gerbil ( Gerbilliscus spp.), greater kudu ( Tragelaphus strepsiceros), honey badger ( Mellivora capensis), and white-tailed mongoose ( Ichneumia albicauda). Our isolation of T. gondii from white-tailed mongoose and honey badger was a unique finding. All tissue samples were negative for N. caninum. The study increases our knowledge on the occurrence of protozoan parasites in populations of wild and domestic animals in South Africa.

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.
