Abstract
Bu çalışmada, Francisella tularensis (F. tularensis)’e karşı gelişen antikorları saptamak için bir Enzyme- Linked Immunosorbent Assay (ELI SA) prototipi ve kristal viyole boyalı bir mikroaglütinasyon test (MAT) antijeni geliştirildi. Ayrıca konfirme edici Western blot (WB) tekniği de serumlara uygulandı. Alınan sonuçlara göre MAT, ELISA ve WB testlerinin tanısal duyarlılıkları %100 olarak bulunurken, özgüllükleri sırası ile %100, %98 ve %96 olarak bulundu. Geliştirilen MAT ve ELISA ile 72 insan serumunda seropozitiflik oranı her iki teste de %4.2 olarak bulunurken, 190 koyun serumunda MAT ve ELISA seropozitifliği sırası ile %3.2 ve %4.7 olarak bulundu. Alınan sonuçlara göre ülke mizde tularemi insan ve hayvanlarda varlığını sürdüren bir infeksiyondur. Ancak daha sağlıklı epidemiyolojik yorum yapabilmek için daha çok sayıda seruma ve farklı hayvan türleri ile çalışılmasına ihtiyaç bulunmaktadır. Sonuç olarak, ELISA ve konfirme edici Western blotting kombinasyonunun tulareminin serolojik tanısında kullanılabilecek uygun bir kombinasyon olduğu düşünülmektedir.
In this study, a microagglutination test (MAT) antigen stained by crystal violet and an in house Enzyme- Linked Immunosorbent Assay (ELISA) prototip were developed in order to detect antibodies against Francisella tularensis. Besides, Western blot technnique was used as the confirmatory test. According to the results, diagnostic sensitivity of MAT, ELISA and WB was 100%, while diagnostic specificities of these tests were 100%, 98% and 96%, respectively. Seropositivity rates of serum samples taken from 72 human were 4.2% for both tests. Seroposi tivity rates of 190 serum samples from sheep were 3.2% for MAT and 4.7% for ELISA. Results seem that tularemia exists in both humans and in animals. However, in order to make more definitive evaluation about the disease, more serum samples taken from various animal species are needed to be tested for this disease. As conclusion, it was thought that ELISA and confirmatory Western blot will be suitable combination for serologic diagnosis of tularemia.
