  Objective: Neospora caninum is a protozoon parasite that has a worldwide distribution and mainly causes abortion in cattle and current serological evidence shows that the disease may be also zoonotic. Wild birds play a role as a reservoir of the disease in nature. The study aimed to determine the prensence of N. caninum in wild birds. Methods: In this study, the presence of neosporosis in wild birds (n=55) including 22 different species found in the western side of Turkey, was investigated by polymerase chain reaction (PCR). In addition, PCR positive samples were confirmed by sequencing, BLAST, and phylogenetic analysis using MEGA7. Results: Obtained results showed that the presence of N. caninum DNA was 5.45% (3/55) in brain-heart homogenates wild birds. The bird species which were found positive for N. caninum were little owl (Athene noctua), common buzzard (Buteo buteo), and little tern (Sternula albifrons). According to phylogenetic analysis and BLAST, all samples were compatible with reference N. caninum isolates. Conclusion: To the best of authors’ knowledge, this is the first study detecting N. caninum in little tern. In future studies, it may be interesting to investigate the prevalence of N. caninum in other wild animals to elucidate the transmission properties.

  Objective: Blastocystis is a common protozoan parasite detected worldwide. This study aims to investigate the in vitro inhibitory effect of ethyl alcohol extracts of Tunceli garlic (Allium tuncelianum) on growth of Blastocystis ST3 subtype. Methods: Blastocystis ST3 were grown in 3 ml Jones’s medium containing A. tuncelianum prepared at five different concentrations for 72 hours at 37°C. Distilled water was used as negative control whereas metronidazole (MTZ) and trimethoprim-sulfamethoxazole (TMP-SMX) prepared in 0.1, 0.5 and 1 mg/ml of concentrations was used as the positive control. Results: According to the results, the MIC90 of the A. tuncelianum was 115 mg/ml at 72 hours. MIC90 of MTZ was 1 mg/ml at 72 hours (94.96%). TMP-SMX had the highest growth MIC90 effect which was reached at 1 mg/ml concentration during 24 hours (88.18%). The growth inhibitory effect of A. tuncelianum extract increased gradually in all doses and timepoints. Conclusion: In this study, obtained findings show the potential inhibitory effect of A. tuncelianum plant extract against Blastocystis ST3 which causes symptomatic diarrhea in humans. It may be recommended to consume the whole A. tuncelianum plant as food supplement. A. tuncelianum extract could be considered as an alternative for the potential treatment of Blastocystis infection.
