Identification and Molecular Characterization of Otobius Megnini (Ixodida: Argasidae) Seen in Humans in Mus Province, Turkey
(Acarological Society Iran, 2022) Karakus, Ayse; Yilmaz, Ali Bilgin; Karaca, Servet; Dik, Bilal; Denizhan, Vural
Otobius megnini (Ixodida: Argasidae) is a cosmopolitan soft tick that parasitizes humans as well as domestic and wild animals. The larval and nymph stages of this tick usually feed by parasitizing in the ear canal. The material of this study consists of ticks collected during ear cleaning in approximately 496 people coming with the complaint of ear pain in state hospitals in Bulanik and Malazgirt districts of Mud province, eastern Turkey. As a result of microscopic examination performed on ticks collected from humans, O. megnini tick was determined and molecular identification was made for definitive diagnosis. The 16S rRNA gene fragment of the tick was amplified by PCR. Obtained PCR products were 360 bp. The PCR products were analyzed by sequence analysis and compared with the reference sequences in the BLAST and Genbank. A phylogenetic tree was created with MEGA 7 software using Maximum Likelihood model. As a result, the previously identified Otobius megnini in Turkey, was confirmed using molecular methods for the first time.
Molecular Identification of Paramphistomidae Obtained From Ruminants in Van Province
(Ankara Univ Press, 2021) Padak, Yusuf; Karakus, Ayse
This study was aimed to identify Paramphistomum species from infected ruminants (sheep and cattle) by molecular methods between March 2018 and September 2018 at Van municipality slaughterhouse. In the research, the rDNA ITS-2 gene region of adult Paramphistomums was amplified by PCR method. Amplicons 399 bp long were viewed in agarose gel. As a result of bidirectional sequence analysis made from PCR amplicons, Paramphistomum leydeni and Calicophoron daubneyi species were identifyed. Amplicon sequences were compared by BLAST with reference sequences from Genbank. Phylogenetic tree was created with the Neighbor-Joining method by using the MEGA 7 program. Genotypes obtained from isolates were compared for exact or closest similarities. In conclusion, C. daubneyi, which was previously detected by morphological methods in Turkey, in this study, it was identified for the first time by using molecular methods. Also in this study, P. leydeni was reported for the first time in Turkey.
