    Frequencies of blood type A, B and AB in cats from the mediterranean sea coast of the Turkey
    (Ecole Nationale Veterinaire Toulouse, 2010) Arikan, S.; Guzel, M.; Ozturk, A. S.; Simsek, O.
    The aim of the present study was to determine the frequency of blood types in cats located in southern Turkey and the inherent risk of isoerythrolysis in kittens born to parents of unknown blood type. A total of 240 non-pedigree cats stemming from 6 cities of the Mediterranean Sea cost were blood typed by slide agglutination assays: the type A was assessed using an anti-A antiserum prepared from known type B cats, while the type B was determined using the lectin from Triticum vulgaris, then the proportions of mating carrying a risk for neonatal isoerythrolysis were calculated. The overall proportions of type A, type B and type AB were 72.1%, 25.4% and 2.5% respectively and the specific prevalence of these blood types were relatively homogeneous among the 6 cites. Considering that all type B cats possess high serum titre of anti-A antibodies, the calculated mean risk for neonatal isoerythrolysis was high (18.9%), ranged from 9.9% to 22.0% according to the cities. These results clearly demonstrate that not-typed transfusion or mating between unknown blood type cats carries a high risk for incompatibility reactions because of the relatively high type B prevalence and lead to strong recommendation for blood typing cats.

    Relationships among Crataegus accessions sampled from Hatay, Turkey, as assessed by fruit characteristics and RAPD
    (Springer, 2011) Serce, S.; Simsek, O.; Toplu, C.; Kamiloglu, O.; Caliskan, O.; Gunduz, K.; Ozgen, M.
    The genus Crataegus known as hawthorns, is the largest genus among the Maloideae, which comprises 265 species. Turkey is one of the genetic centers of Crataegus and there are more than 20 species found in Turkey. The fruits of Crataegus are used as food and have high flavonoid, vitamin C, glycoside, anthocyanidin, saponin, tannin, and antioxidant levels. In this study, we attempted to characterize 15 Crataegus accessions sampled from Hatay, located in Eastern Mediterranean region of Turkey. The accessions belonged to several species; C. aronia (L.) DC. var. aronia, C. aronia var. dentata Browicz, C. aronia var. minuta Browicz, C. monogyna Jacq. subsp. azarella (Griseb.) Franco, and C. orientalis Pall. ex M. Bieb. var. orientalis. Fruit characteristics of the accessions exhibited considerable variation. The multivariate, principle component and cluster analyses indicated that the accessions belonged to three groups: (1) C. aronia var. arona accessions; (2) C. aronia var. dentata accessions; and, (3) C. monogyna subsp. azarella and C. orientalis var. orientalis accessions. The principle component analysis results also revealed that the first three components explained 46, 21, and 14% of the variation, comprising a total of 81%. The fruit length and width, leaf area, and soluble solids contents were highly correlated characteristics for the first three components. The 19 RAPD primers generated a total of 107 bands, where 76 of these were polymorphic. The molecular data analyses by principle coordinate and clustering showed similar results to those of pomological characteristics. There were three groups, (1) C. aronia var. arona accessions; (2) C. aronia var. dentata accession; and, (3) C. monogyna subsp. azarella. C. orientalis var. orientalis accession grouped with C. aronia var. arona accessions. Therefore, it can be concluded that, overall, the diversity patterns of pomological and molecular data, generated by RAPD, for Crataegus are in good agreement and the accessions of C. aronia var. aronia, C. aronia var. minuta, C. monogyna subsp. azarella and C. orientalis var. orientalis accessions.
