Development And Evaluation Of Selected Chemoprophylaxis Candidates And A Candidate Live-Attenuated Vaccine For Prevention Of Histomoniasis In Turkeys, Lesleigh Beer May 2019

Development And Evaluation Of Selected Chemoprophylaxis Candidates And A Candidate Live-Attenuated Vaccine For Prevention Of Histomoniasis In Turkeys, Lesleigh Beer

Graduate Theses and Dissertations

Histomoniasis, commonly known as blackhead disease, has increased in prevalence due to the regulatory ban of prophylactics and therapeutics within the past 30 years. The objective of this thesis was to evaluate the efficacy of selected dietary chemoprophylaxis candidates as well as an in vitro live-attenuated vaccine candidate Histomonas meleagridis for prevention of histomoniasis. Chapter one addresses deoxycholic acid and a biliogenic diet intended to endogenously increase production of this secondary bile acid. Deoxycholic acid was effective in vitro but failed to prevent histomoniasis when evaluated during the in vivo experimental disease trial with turkeys. The biliogenic diet did not …


Altered Gene Response To Aflatoxin B1 In The Spleens Of Susceptible And Resistant Turkeys, Kent M. Reed, Kristelle M. Mendoza, Roger A. Coulombe Jr. Apr 2019

Altered Gene Response To Aflatoxin B1 In The Spleens Of Susceptible And Resistant Turkeys, Kent M. Reed, Kristelle M. Mendoza, Roger A. Coulombe Jr.

Animal, Dairy, and Veterinary Science Faculty Publications

Susceptibility and/or resistance to aflatoxin B1 (AFB1) is a threshold trait governed principally by glutathione S transferase (GST)-mediated detoxification. In poultry, domesticated turkeys are highly sensitive to AFB1, most likely due to dysfunction in hepatic GSTs. In contrast, wild turkeys are comparatively resistant to aflatoxicosis due to the presence of functional hepatic GSTAs and other possible physiological and immunological interactions. The underlying genetic basis for the disparate GST function in turkeys is unknown as are the broader molecular interactions that control the systemic response. This study quantifies the effects of dietary AFB1 on gene …

Differential Transcriptome Responses To Aflatoxin B1 In The Cecal Tonsil Of Susceptible And Resistant Turkeys, Kent M. Reed, Kristelle M. Mendoza, Roger A. Coulombe Jr.

Animal, Dairy, and Veterinary Science Faculty Publications

The nearly-ubiquitous food and feed-borne mycotoxin aflatoxin B1 (AFB1) is carcinogenic and mutagenic, posing a food safety threat to humans and animals. One of the most susceptible animal species known and thus a good model for characterizing toxicological pathways, is the domesticated turkey (DT), a condition likely due, at least in part, to deficient hepatic AFB1-detoxifying alpha-class glutathione S-transferases (GSTAs). Conversely, wild turkeys (Eastern wild, EW) are relatively resistant to the hepatotoxic, hepatocarcinogenic and immunosuppressive effects of AFB1 owing to functional gene expression and presence of functional hepatic GSTAs. This study was designed to …

Animal Remains Of Alaybeyi Höyük, Abu Bakar Siddiq Jan 2019

Animal Remains Of Alaybeyi Höyük, Abu Bakar Siddiq

Turkish Journal of Veterinary & Animal Sciences

This paper presents the zooarchaeological observations on animal remains of Alaybeyi Höyük unearthed from 2016 and 2017 excavation sessions. Dated to 4721-4553 cal. BC, Alaybeyi stands so far as the oldest archaeological settlement discovered in northeast Anatolia. Therefore, the faunal assemblage at Alaybeyi offers great opportunity to study the status of animals and their relationships with humans in the largely unexplored Kars-Erzurum plateau covering a period from the Chalcolithic to Late Iron Age. Taxonomic and osteometric analyses show that, like the present day, cattle were dominant over caprines, revealing extensive cattle pastoralism in the region for at least about 7 …

Ecological Surveys On The Parthenogenetic Artemia Populations In The Hypersaline Lakes Of Anatolia, Turkey, Armi̇n Eskandari̇, Yasemi̇n Saygi

Turkish Journal of Zoology

The objective of this study is to provide information on the parthenogenetic Artemia populations in some hypersaline lakes of Anatolia (Tuz, Bolluk, Tersakan, and Acıgöl). Sampling studies were performed for abiotic factors and population parameters between November 2009 and October 2010. During the survey we focused on the local Artemia populations to investigate population dynamics, reproduction, brood size, and cyst and naupliar biometrics. Generally, the Artemia habitats in Anatolia were relatively shallow, and thus they were subject to major seasonal fluctuations. Dramatic declines in population size in Tuz and Acıgöl Lakes were found during this study. All Artemia populations were …

On Tooth Anomalies And The Loss Of Canis Lupus (Mammalia: Carnivora) In Turkey, Eli̇f Yildiz Ay, İrfan Albayrak

Turkish Journal of Zoology

Because of their feeding habits, which are affected by their ranking in the last steps of the food chain, the teeth of carnivores are subjected to great forces during the breaking up and chewing of food when they are hunting. In this sense, missing teeth and tooth anomalies are common in carnivores. This research was based on an examination of the properties of the tooth structures of 25 wolf specimens collected in Turkey between 2014 and 2018. In this study, the excess and missing teeth, tooth fracture, and root anomalies in the lower and upper jaw of the head skeletons …

Morphometric Analysis Of The Skulls Of Domestic Cattle (Bos Taurus L.) And Water Buffalo (Bubalus Bubalis L.) In Turkey, Ermi̇ş Özkan, Abu Bakar Siddiq, Ki̇fayet Oya Kahveci̇oğlu, Muhsi̇n Öztürk, Vedat Onar Jan 2019

Morphometric Analysis Of The Skulls Of Domestic Cattle (Bos Taurus L.) And Water Buffalo (Bubalus Bubalis L.) In Turkey, Ermi̇ş Özkan, Abu Bakar Siddiq, Ki̇fayet Oya Kahveci̇oğlu, Muhsi̇n Öztürk, Vedat Onar

Turkish Journal of Veterinary & Animal Sciences

A total of 20 domestic cattle (Bos taurus L.) and 15 water buffalo (Bubalis bubalis L.) skulls were analyzed in this study. All of the specimens belonged to female individuals. Using a total of 27 craniometric measurements from each of the skulls, 9 indices were calculated. Although there were statistically significant differences between the linear measurements of the skulls of both species, while calculating the indices with their ratios, the values of the measurements of the facial area were determinative in the craniology. Among these indices, the facial index 1 value was statistically significant (P < 0.01) in the comparison of these two species. On the other hand, while considering the orbit and foramen magnum measurements, in contrast with the transversal measurement, the height was more determinant for their index and form.
