Toksoplazma Gondii Yönünden Seropozitif Köpeklerin Serum Total Sialik Asit ve Seruloplazmin Düzeylerinin Belirlenmesi

Öz

Bu çalışmada, İstanbul’un çeşitli barınaklarında bulunan ve Toxoplasma gondii seropozitif olan köpeklerin serum sialik asit (TSA) ve seruloplazmin (CP) düzeylerinin araştırılması ve bu düzeylerin arasında olası ilişkinin incelenmesi hedeflendi. Bu amaçla indirekt floresan antikor testi (IFAT) sonuçlarına göre T. gondii seronegatif bulunan 15 sağlıklı köpek ile seropozitif bulunan 25 enfekte köpekten kan örnekleri alındı ve serumları çıkarıldı. TSA ve CP değerleri ölçüldü. Yapılan analizlerde hasta ve kontrol gruba ait TSA düzeyleri sırası ile 17.20±0.55 mg/dl ve 15.97±0.55 mg/dl olarak tespit edildi. Buna göre hasta ve kontrol gruba ait serum TSA düzeyleri arasında istatistiksel olarak önemli bir fark bulunmadı (P>0.05). Serum SP ortalamaları hasta ve kontrol gruplarda sırasıyla 16.49±1.11 mg/dl ve 10.28±1.63 mg/dl olarak bulundu. Hasta grubun serum CP düzeyleri kontrol grubuyla karşılaştırıldığında anlamlı olarak yüksek bulundu (P<0.01). Diğer taraftan hasta ve kontrol grubuna ait serum TSA ile CP düzeyleri arasında herhangi bir korelasyon bulunamadı. Gruplar arası serum TSA düzeyinin anlamlı bulunmaması hastalığın kronik döneminde olduğunu ve hücresel hasarın ortadan kalktığını düşündürmektedir. T. gondii ile enfekte köpeklerde yüksek serum seruloplazmin düzeyinin, bu enfestasyon sonucunda oluşan hücre hasarının bir sonucu olduğu ve serum seruloplazmin düzeyinin bu hastalığın serolojik bulgularına yardımcı olarak kullanılabileceği kanaatine varılmıştır.

Determination of Serum Total Sialic Acid and Ceruloplasmin Concentrations in Toxoplasma Gondii Seropositive Dogs

Öz

This study aimed to investigate serum total sialic acid (TSA) and ceruloplasmin (CP) levels and their possible correlation in Toxoplasma gondii seropositive dogs. The study was conducted on the dogs that had been kept in doghouses located in the province of Istanbul. Based upon indirect fluorescence antibody test (IFAT) results, 15 T. gondii seronegative dogs and 25 seropositive infected dogs were included in the study. Blood samples were collected from each dog and serums were obtained. Subsequently, TSA and CP concentrations were measured. For serum TSA concentration, no significant difference was found between control (17.20±0.55 mg/dl) and infected dogs (15.97±0.55 mg/dl) (p>0.05). On the other hand, serum CP concentration was significantly higher in seropositive dogs (16.49±1.11 mg/dl) compared to control dogs (10.28 ±1.63 mg/dl) (p<0.01). No correlation was found between serum TSA and serum CP. Absence of a significant difference between groups for serum TSA might be related to the fact that the disease was in chronic stage, and the severity of cellular damage might have been decreased. Elevation of serum CP in T. gondii infected dogs is most likely related to cellular damage as a consequence of infection. We suggest that serum CP can be used as an additional prognostic parameter in toxoplasmosis in support to other serologic parameters.
