The pathotypes of Cercospora beticola, causal agent of sugar beet leaf spot disease, were identified by application of pathogenicity test using 100 isolates obtained from the provinces with intensive sugar beet cultivation. For the identification of pathotypes, five sugar beet cultivars were used each with different resistance factors. Cultivar reactions were determined by inoculation of cultivars with the isolates under controlled conditions and measuring disease severity on the $15^{th}$ day according to the 1-9 KWS Scale. Based on the reactions of the five cultivars, a total of 15 pathotypes were detected. All employed sugar beet cultivars were resistant to Pathotype no:1 comprising most of the isolates. Genetic diversity of the causal agent was characterized by AFLP reaction. The products acquired at the end of AFLP reaction were detected by means of Beckman CEQ 8800 DNA Capillary Series Analysis and the results obtained were evaluated according to the similarity index UPGMA. For the genetic analysis of C. beticola isolates, 9874 polymorphic fragments of sizes between 100 and 500 bp were analysed which were generated by nine primers. The dendrogram derived from AFLP analysis depicted the existence of five different subgroups. The polymorphism rate among isolates was 91.13% and the dendrogram distribution of the pathotypes obtained by pathogenicity indicated that pathotypes were not discriminated and did not compose any groups.

Objective: The aim of this study is to investigate the influence of pregnancy on prognosis of thyroid cancer. Methods: A total of 72 patients aged between 15-45 years who underwent total or subtotal thyroidectomy and subsequently radioablation were followed up under suppression. Individuals who had term pregnancies after diagnosis of cancer (group 1, n: 36) and who were non-pregnant (group 2, n:36) were included in the study. Both groups were compared in terms of scintigraphic relapse and metastasis, ultrasonographic relapse, stage change of lympadenopathy at the beginning and at the end of the study. Results: Relapse was detected in 4 out of 36 pregnant patients (11.1%) and in 5 out of 36 non-pregnant patients (13.9%) with no significant difference between groups (p=1.00). Pathologic lymphadenopathy was detected in 2 out of 36 pregnant patients (5.6%) and in 2 out of 36 non-pregnant patients (5.6%) (p=1.00), and metastasis in 3 (8.3%) and in 1 (2.8%), respectively (p=0.61). While stage change was detected in only one pregnant patient (2.8%), and none of the non-pregnant again there was no significant difference (p=1.00). Conclusions: We conclude that pregnancy does not have an influence on prognosis of thyroid cancer.
