Toxoplasma gondii is a protozoon parasite that causes congenital toxoplasmosis, as well as other serious clinical presentations, in immune compromised humans. Analyses of the prevalence and genotyping of strains from the definitive host and intermediate hosts will help to understanding the circulation of the different strains and elucidating the role of the genotype(s) in human toxoplasmosis. Turkey has a specific geographic location bridging Africa, Europe, and Asia. We hypothesized that T. gondii strains may have been transferred to Turkey from these continents via migratory birds or vice versa. The present study aimed to assess the prevalence of toxoplasmosis in wild birds of prey of İzmir and Manisa provinces as well as genetically characterize T. gondii strains from these wild birds to show the relation between bird strains and neighboring stray cats as well as human strains previously isolated in Turkey. Tissues obtained from 48 wild birds were investigated for the presence of T. gondii DNA and then bioassayed in mouse. Isolated strains were genotyped using 15 microsatellite markers. The prevalence of T. gondii DNA was found to be 89.6% (n: 43/48) in wild birds. Out of 43 positive samples, a total of 14 strains were genotyped by 15 microsatellite markers. Among them, eight were type II, three were type III and three were mixture of genotypes (two type II/II and one was II/III). These are the first data that showed the presence of T. gondii and types II and III genotypes in wild birds of Turkey. Moreover, Africa 1 was not detected. In addition, cluster analysis showed that T. gondii strains within type II and III lineage have close relation with strains previously isolated from stray cats in İzmir. Further studies are required to isolate more strains from human cases, other intermediate hosts, and water sources to reveal this relation.

Hemosporidian parasites that cause infections in poultry and death in susceptible animals show a global distribution. In this distribution, the role of infected wild birds migrating among different regions of the world is great. Hatay, where migratory birds enter Turkey, is an active region in terms of vectors, disease agents and hosts. In this study, it was aimed to investigate the prevalence of Haemoproteus and Leucocytozoon parasites in wild birds of Hatay province by microscopic and molecular methods. Blood samples were taken from a total of 50 wild birds belonging to three orders, eight species. On the microscopic examination, Haemoproteus spp. infection 18% (9/50) and mix infection (Haemoproteus spp. and Leucocytozoon spp. ) 4% (2/50) was detected while on the PCR examination, H. columbae 20% (10/50), Leucocytozoon spp. 2% (1/50), mix infection 4% (2/50) was detected. As a result, haemosporidian parasites were detected approximately on one of every four wild birds (microscopic 22%, molecular 26%).

“…Also, tachyzoite and tissue cyst (bradyzoites) production occurs through asexual reproduction in felines and other intermediate hosts such as mammals and birds (1). Oocysts which are highly resistant to environmental conditions and meat containing tissue cysts are the main factors that spread the infection among wild animals (2,3). The Eurasian badger (Meles meles) belonging to the family Mustelidae lives in Europe and Eurasia located in the northern hemisphere.…”

Toxoplasma gondii is an obligatory intracellular protozoon parasite that causes toxoplasmosis in humans and all warm-blooded animals. In this study, we aimed to investigate the presence of T. gondii DNA in a Eurasian badger (Meles meles) that was found dead in the wildlife area of Izmir. According to the results of real time polymerase chain reaction, T. gondii REP gene was found to be positive in the Eurasian badger brain homogenate. In conclusion, Eurasian badger, a known carnivore, can be a potential source of toxoplasmosis in the natural settings of İzmir, Turkey. ÖZToxoplasma gondii, insanlarda ve tüm sıcakkanlı hayvanlarda toksoplazmozise neden olan zorunlu hücre içi protozoon bir parazittir. Bu çalışmada, İzmir'in yaban hayatında ölü olarak bulunan bir Avrasya porsuğunda (Meles meles) T. gondii DNA varlığının araştırılması amaçlanmıştır. Real time Polimeraz Zincir Reaksiyonu (PZR) sonucuna göre T. gondii REP geni Avrasya porsuğunun beyin homojenatında pozitif bulunmuştur. Sonuçta önemli bir etobur olan Avrasya porsuğunun İzmir'in doğal çevresinde potansiyel bir toksoplazmoz kaynağı olabileceği gösterilmiştir.
