Development Of A Turkey Coccidiosis Vaccine Candidate: An Attenuated Line Of The Protozoan Parasite, Eimeria Meleagrimitis, Thilakar Rathinam

Graduate Theses and Dissertations

Coccidiosis is an economically important enteric disease of poultry caused by protozoan parasites belonging to the genus Eimeria. Drugs are most commonly used to control coccidiosis. Widespread usage of anticoccidial drugs in the field has resulted in development of drug resistant strains and consequently decreased drug efficacy. An alternative control strategy using attenuated vaccines is desired. A series of experiments was designed to identify, isolate and attenuate a strain of a common and pathogenic species of Eimeria of turkeys, E. meleagrimitis.

Sensitivity of field isolates of turkey coccidia to the anticoccidials drugs amprolium, clopidol, diclazuril, and monensin was investigated. A …

In The Words Of The Medical Tourist: An Analysis Of Internet Narratives By Health Travelers To Turkey, Margaret E. Ozan-Rafferty, James Allen Johnson, Gulzar H. Shah, Attila Kursun

Health Policy and Management Faculty Publications

Background: Patients regularly travel to the West for advanced medical care, but now the trend is also shifting in the opposite direction. Many people from Western countries now seek care outside of their country. This phenomenon has been labeled medical tourism or health travel. Information regarding health travelers’ actual outcomes, experiences, and perceptions is lacking or insufficient. However, advanced Internet technology and apps provide information on medical tourism and are a vehicle for patients to share their experiences. Turkey has a large number of internationally accredited hospitals, is a top tourism destination, and is positioning itself to attract international patients. …

Hepatitis C virus (HCV) genotype 1 was found to be dominant in Turkey. In this study, HCV genotypes were examined in the Adana and Antakya regions of Turkey. Materials and methods: The study consisted of 639 HCV-RNA–positive patients with chronic HCV infection in Adana (214 males and 101 females) and Antakya (139 males and 185 females) in Turkey. Real time-polymerase chain reaction was used for genotype determination. Results: In Antakya, it was determined that the percentages of genotypes of type 1a (0.31%), 1b (86.73%), 2 (9.26%), 3 (0.93%), and 4 (2.78%) were compatible with the nationwide results seen in Turkey. …

Both cattle and dogs were examined in modern and rural dairy farms that had a history of abortion over 5%. The blood samples were collected from 427 aborted cattle and the sera were tested using a commercial ELISA test kit. Additionally, a necropsy procedure was carried out on the fetuses and calves dead within 2 months after birth; the tissue samples were evaluated by histopathologic, immunoperoxidase, and PCR techniques. Eighteen dogs in close contact with the cattle in the same field were included in the study and blood and feces samples were collected. The feces samples were analyzed by copro-PCR …

The Relationship Between Seropositivity And Tissue Cysts In Sheep Naturally Infected With Toxoplasma Gondii, Kader Yildiz, Oğuz Kul, Sami̇ Gökpinar, Hasan Tarik Atmaca, Yilmaz Emre Gençay, Aycan Nuri̇ye Gazyağci, Cahi̇t Babür, İsmayi̇l Safa Gürcan

Skeletal muscles (tongue, masseter, leg, intercostal, and diaphragmatic muscles) and brain samples of 100 sheep at slaughter were analysed for the presence of T. gondii tissue cysts along with serum IgG titres. Two methods of isolation by percoll gradient centrifugation and tissue microarray (TMA) technique with immunoperoxidase staining were used. Seropositivity was detected in 88% (88/100) of sheep sera analysed by indirect fluorescent antibody test. Tissue cysts were observed in 46 (52.3%, 46/88) and 15 (17%, 15/88) of the seropositive sheep with the isolation technique and TMA and immunoperoxidase staining, respectively. The diameters of the tissue cysts were 25–58 × …

Serological Survey Of Equid Herpesvirus 3 Infection In Turkish Horses, Veysel Soydal Ataseven, Firat Doğan, Seval Bi̇lge Dağalp, Mehmet Tolga Tan, Köksal Altinbay, Cafer Tayyar Ateş

Turkish Journal of Veterinary & Animal Sciences

Sera from 1133 Turkish horses were obtained and tested for equid herpesvirus 3 (EHV-3) antibodies using a sero-neutralisation test. The sample consisted of 420 privately owned working horses from 2 regions of Turkey, 428 brood horses from private stud farms and breeding stations, and 285 racehorses from private stud farms. Neutralising antibodies against EHV-3 were found in 287 (25.3%) of the 1133 analysed sera. The highest seroprevalence for EHV-3 was detected in the brood horses (51.2%), followed by the racehorses (10.2%), and the working horses (9.3%). The seroprevalence rates tended to be higher in female horses than in male horses …

Metazoan Parasites Of Brown Meagre (Sciaena Umbra L. 1758) Caught Near Gökçeada, Turkey, Ahmet Akmirza

Turkish Journal of Veterinary & Animal Sciences

This study was conducted between July 2011 and January 2012 in Gökçeada, Turkey, to determine the metazoan parasite fauna of brown meagre (Sciaena umbra). The metazoan parasite fauna of 53 brown meagre samples was investigated and a total of 7 parasite species [Anoiktostoma coronatum, Paracryptogonimus aloysiae (Digenea), Longicollum pagrosomi (Acanthocephala), Contracaecum fabri (Nematoda), Trachelobdella lubrica (Hirudinea), Nerocila bivittata, and praniza larvae (Isopoda)] were identified. It was determined that Paracryptogonimus aloysiae was the dominant parasite species of brown meagre with the prevalence of 66.04% in this region. Anoiktostoma coronatum and Paracryptogonimus aloysiae were reported for the first time in Turkey.
