Çankırı Yöresi Sığırlarında Toxoplasmosis'in Seroprevalansı

Öz

Bu çalışma, Çankırı İli'ne bağlı 12 köyde toplam 240 sığır serumu üzerinde yapılmıştır. Bu serumlar, Toxoplasma gondii antikorlarının araştırılması amacıyla, Latex Aglütinasyon Test (LAT) ve Sabin-Feldman Test (SFT) ile incelenmişlerdir . Latex Aglütinasyon Test sonuçlarına göre; 0-1 yaş grubu 120 sığırın 16'sı (%13 . 3) pozitif bulunurken, 1 yaşın üzeri 120 sığırın 62'si (%51.6) pozitif olarak tespit edilmiştir. LAT'de pozitifbulunan 78 adet (%32.5) serumun dişi ve erkeklerde bulunma oranı da sırasıyla %40.6 ve % 14.6 olarak saptanmıştır. LAT sero-pozitifliğinin titrelere göre dağılımı; 1/64'de %41.0, 128'de %44.8, 1;256'da %10 . 2 ve 1/512'de %3.8 şeklinde olmuştur. Ayrıca 1/32 dilüsyonda 47 (% 19 . 5) zayıf pozitiflik görülmüştür . Aynı serumlarda SFT sonuçlarına göre; 0- 1 yaş grubunda 76 (%63.3) , 1 yaşın üzerindeki grupta ı04 (%86.6) sero-pozitivite tespit edilmiştir. Toplam 180 (%75.0) pozitif olgunun dişi ve erkeklerde bulunma oranı ise sırasıyla; %75.7 ve %73.3 olarak saptanmıştır. SFT sero-pozitifliğinde titrelere göre dağılım; 1/16 titrede %37.2, 1/64 titrede %47.2 ve 1/256 titrede %15.5 oranlarında gerçekleşmiştir. LAT ve SFT arasındaki ilişkinin X² (Ki kare) ile yapılan istatistiksel analizinde, iki test arasındaki fark önemli bulunmuştur (p<0.05).

The Seroprevalence of Toxoplasmosis in Cattle of Çankırı Region.

Öz

This study was conducted in 12 villages representing the Çankırı province and various parts of this province using totally 240 catt- . le blood sera. These blood sera were examined with respect to the detection of the antibodies against T.gondii using Latex Agglutination Test (LAT) and Sabin-Feldman Test (SFT). According to the LAT results; ı6 of the ı20 cattle in 0-1 age group 13.3% were found to be sero-positive while 62 of the 120 cattle in 1 year old or older age group 51.6% were found to be sero-positive. The rate of positivity in females was 40.6% while this rate was 14 . 6% in males. The distribution of the sero-positivity in LAT with regards to the titers was 41.0% at ı/64 dilution, 44.8% at 1/128 dilution, 10.2% at 1/256 dilution and 3.8% at 1;512 dilution. According to the SFT results of the same blood sera sero-positivity was determined in 76 cattle (63 .3%) in 0-1 age group and ıo4 cattle (86.6%) in 1 year old or older age group. The rate of sero-positivity in females was 75.7% and 73.3% in males, total 180 (75 .0%) sero- positive cases. The distribution of the sero-positivity in SFT wi.th regards to the titers was 37.2% at 1 /16 dilution, 47.2% at 1 /64 dilution and 15 . 5% at 1/256 dilution. According to the xz Test used for the statistical analysis, the differences between LAT and SFT results were statistically significant (p<0.05).
