    Alteration in blood gases in cats naturally infected with Aelurostrongylus abstrusus
    (Wiley, 2011) Yildiz, K.; Duru, S. Y.; Gokpinar, S.
    Four cats were presented with respiratory signs and first-stage larvae of Aelurostrongylus abstrusus were found in faecal samples. Anthelmintic treatment was given to the infected cats and venous blood gases were analysed during the treatment period. Blood gas analysis suggested hypoventilation and respiratory acidosis in infected cats. Hypoventilation may be the result of airway obstruction by adults and larvae in respiratory bronchioles and the alveolar canals. The blood gas values had returned close to the physiological range by two months after treatment. Assessment of respiratory acidosis may aid development of additional treatment methods in cats infected with A. abstrusus.

    Investigation of Theileria annulata and Theileria buffeli/orientalis in Cattle from Kirikkale - Turkey by Reverse Line Blotting Analyses
    (Israel Veterinary Medical Assoc, 2016) Gokpinar, S.; Aydenizoz, M.
    This study was aimed at determining the prevalence of T. annulata and T. buffeli/orientalis species in cattle from Kirikkale province using reverse line blotting (RLB) and comparing the results with microscopy. Blood samples were collected from 294 cattle from 9 districts of Kirikkale (Centre, Bahsili, Baliseyh, Celebi, Delice, Karakecili, Keskin, Sulakyurt and Yahsihan) between May-October 2010. From cattle that has at least grazed once and over one year old of age. A blood smear from ear tip peripheral blood was prepared and a venous blood sample from jugular vein was taken. Blood smears were inspected and documented for the presence of Theileria spp. piroplasms after Giemsa staining. Venous blood samples were used for extraction of DNA for Reverse Line Blotting (RLB) analyses. Out of 294 samples analyzed 44 (15%) were found to have Theileria spp. piroplasms with microscopic examination, while 77 (26.1%) harbored T. annulata as determined by RLB. In none of the samples T. buffeli/orientalis was detected. The prevalence of Theileria spp. and T. annulata was highest in Keskin district. This study presents the first investigation of Theileria species in cattle from Kirikkale province.

    Prevalence and Concentration of Sarcocystis spp. Microscopic Cysts in Sheep Muscles Using Percoll Gradient Centrifugation
    (Israel Veterinary Medical Assoc, 2014) Gokpinar, S.; Yildiz, K.; Gurcan, I. S.
    Percoll gradient centrifugation can purify different parasitic stages from tissues or faeces of hosts. Sarcocystis tenella and Sarcocystis arieticanis develop microscopically visible cysts in sheep muscles. In this study, the distribution of microscopic cysts were determined in different muscles groups of sheep naturally infected with Sarcocystis spp. by using percoll gradient centrifugation. Sarcocystis spp. microscopic cysts were detected as 91% of sheep. S. tenella and mixed infections with S. tenella and S. arieticanis were observed in the tissue samples at a prevalence of 91% and 18.7%, respectively. Sarcocystis species cysts were most prevalent in the tongue muscle tissue at a rate of 80%. The cysts were observed a rate of 73%, 69% and 61% in the masseter, intercostal muscles and diaphragm, respectively. The relationship between the cysts present and the different muscles groups was significantly different (p<0.001). The number of microscopic cysts ranged from 4-476 (mean 235) per 5 grams muscle samples. Percoll gradient centrifugation should be considered as an alternative method for detection of Sarcocystis spp. microscopic cysts in host muscles.
