Objective: The aim of this study is to detect the Anaplasma/Ehrlichia species of cattle and ticks and to provide knowledge on the prevalence of these species during sampling periods., Methods: A total of 679 blood and 186 tick samples were collected from the Osmanbükü, Akçaova, Dalama, and Söke districts of Aydın. The samples were screened with genus polymerase chain reaction (PCR) for Anaplasma/Ehrlichia spp., species-specific polymerase chain reaction for Anaplasma marginale and A. centrale, and nested PCR for A. bovis and A. phagocytophilum., Results: A. centrale was detected in Söke during September and in Dalama and Akçaova during March, June, September, and December. A. marginale was detected in Osmanbükü during June; in Söke during March and December; in Akçaova during June, September, and March; and in Dalama during the entire sampling period. A. phagocytophilum was detected in all regions during the entire sampling period. None of the samples were positive for A. bovis. Mixed infections were detected in 50 blood samples. A. marginale and A. phagocytophilum were detected in the tick samples., Conclusion: In this study, A. phagocytophilum was abundantly detected compared with A. marginale and A. centrale. A. phagocytophilum and A. centrale were extensively found in Akçaova and A. marginale was mostly seen in Dalama. Parasites were extensively detected in September and March. The analysis indicated that collected ticks were infected with different Anaplasma/Ehrlichia species.

Objective: This study has been planned to investigate some biological features of Hyalomma marginatum, which is one of the important vectors in the world and in our country., Methods: The study started with the adult H. marginatum which were collected from cattle in the field and attempts were made for these to be adapted to the laboratory by breeding in the laboratory throughout a generation. Unfed adult ticks and unfed larvae were bred on the rabbit ear while unfed nymphs were bred on the calf ear. The biologic development stages of this tick kind, except for sucking blood stage, passed in an incubator which was at a temperature of 28°C and 85% relative humidity, while the unfed active stages passed in an incubator which was at 18°C and 85% relative humidity to conserve for a long time., Results: Unfed females on rabbits were full and fell in approximately 15 days, began to ovulate 20.5 days later and ovulated for 16 days. The larvae which hatched out approximately 29 days later became active in 8.5 days. These larvae sucked blood from rabbits for 14.5 days and abandoned these animals as full nymphs. Unfed adult ticks, which existed as a result of these nymphs casting off their skin in approximately 26 days, became active by completing their cutinization in approximately 10 days., Conclusion: At the end of the study, it was determined that H. marginatum showed 2 different behaviors in rabbits. According to this, the total life cycle in the laboratory environment changed by between 97 and 182 days and lasted approximately 138.5 days.

The present study was carried out to find out the prevalence of tropical theileriosis in the Aydin region and to determine immune status of cattle vaccinated with Theileria annulata schizont vaccine using the indirect fluorescence antibody test (IFAT) during and after the disease season. A total of 236 out of 466 cattle found to be seronegative with IFAT were vaccinated in the Aydin region (Cine, Incirliova, Nazilli, and Centrum) before the disease season (March). The remaining cattle (230/466) served as controls. Blood samples were collected from all cattle following the vaccination once in each month of April, June, September, and December (a total of 4 times) to determine the incidence of the disease using microscopic and serologic evaluations. Results indicated that the incidence of the disease varied among the regions. Clinical theileriosis was found in a total of 22 cattle (10 vaccinated, 12 unvaccinated) during the disease season.

Fecal specimens of a total of 200 dogs were examined by native, Fulleborn's floatation and Benedek's sedimentation methods to determine the prevalence of gastro-intestinal helminth infections in stray dogs in the Aydin Municipality Animal Shelter and the Kuşadasi Municipality Animal Shelter. Helminth infections were encountered in 82 (41%) of the fecal samples examined. One cestode egg and four nematode eggs were found in the infected fecal samples. The helminth eggs found were identified as follows: Taenia spp. (7.5%), Toxacara spp. (20%), Toxascaris leonina (1%), Uncinaria stenocephala (21%) and Trichuris vulpis (1.5%). No trematode eggs and nematode larvae were found in this study.
