YILDIZ, Kader/0000-0001-5802-6156; YILDIRAN, Fatma Azize BUDAK/0000-0001-7031-6834WOS: 000276347800012In present study, it was aimed to determine molecular characterization of Echinococcus granulosus obtained from sheep. For this purpose, DNA isolation was done from germinal membrans and protoscolices of 24 hydatic cyst samples obtained from different organs of infected sheep and then DNA samples were scanned by RAPD-PCR using 16 primers. Echinococcus granulosus G1 strain was used as reference material. Only 4 of these 16 primers (AP2, AP4, OPB12 and G05) gave the typical RAPD band patterns in both sheep isolates and the reference G1 strain. The single band of 250 bp occurred by AP2 primer was common in both sheep isolates and G1strain According to result, AP2 primer can be successfully used for separation of G1 strain in different isolates. The results indicated that all sheep isolates sampled in this study can be assumed in the same Echinococcus granulosus strain

Seroprevalence of Neospora caninum in dairy cattle ranches with high abortion rate: Special emphasis to serologic co-existence with Toxoplasma gondii, Brucella abortus and Listeria monocytogenes

YILDIZ, Kader/0000-0001-5802-6156; Celebi, Bekir/0000-0002-4545-5573; Babur, Cahit/0000-0002-6524-3260WOS: 000271052900029PubMed: 19592171The aim of this study was to determine seroprevalence of Neospora caninum in dairy cattle ranches with higher abortion rates and co-existence of Neospora caninum, Toxoplasma gondii, Brucella abortus, and Listeria monocytogenes antibodies. The blood samples were collected from dairy cows with history of abortion (n = 234) as well as from pregnant cows that were (n = 323) kept in the same ranches. N. caninum seroprevalence was 10.77% (60/557). The co-existence rate of N. caninum seropositivity with T. gondii, B. abortus and L. monocytagenes was 24.77% (138/557), 13.82% (77/557) and 42.85% (162/378), respectively. Only one animal had significant antibody titers for all analyzed infectious agents. The seroprevalence of N. caninum and T. gondii were significantly higher in pregnant cows than aborted cows (p < 0.05 and p < 0.001, respectively). As a result, the comprehensive data generated through this study can significantly contribute to understanding of serologic association of N. caninum with T gondii, B. abortus and L monocytogenes in pregnant and aborted dairy cows.
