Özet
Amaç: Bu çalışma, oksfendazol+oksiklozanid kombinasyonunun Türkiye antiparaziter ilaç pazarına girişinden otuz yıl sonra etkinliğini yeniden değerlendirmek için yapılmıştır. Gereç ve Yöntem: Çalışmada, gastrointestinal nematodlarla enfekte otuz iki koyun kullanılmıştır. Koyunlar, dışkıda gram başına yumurta sayısına göre seçilmiş ve her biri 16 hayvandan oluşan iki gruba ayrılmıştır. Grup I'deki hayvanlar 0. günde, sırasıyla 7.5 mg/kg ve 15 mg/kg vücut ağırlığı dozunda oksfendazol+oksiklozanid kombinasyonu ile oral olarak tedavi edilmiştir. II. gruptaki hayvanlara tedavi yapılmayıp, kontrol grubu olarak ayrılmıştır. Her hayvandan dışkı örnekleri 0. gün (tedavi günü); tedavi sonrası 7., 14. ve 21. günlerde toplanmıştır. Antelmintik tedavinin etkinliğini belirlemek için McMaster metodu ile gram dışkıdaki yumurta sayımı ve dışkı yumurta sayımı azaltma testi uygulanmıştır. Bulgular: Dışkı örneklerindeki yumurta sayılarında tedavi ve kontrol gruplarında 0. gün istatistiksel olarak fark tespit edilmemiştir. Tedavi sonrası 7. günde, sadece bir koyunun dışkı örneğinde çok az yumurta bulunmuş ve tedavi grubu için ortalama yumurta sayısı 66.7 ± 66.7 olarak belirlenmiştir. Tedaviden sonraki 14. ve 21. günlerde dışkıdaki yumurta sayıları, tedavi grubunda sıfıra kadar düştü ancak tedavi edilmeyen kontrol grubunda önemli bir değişiklik görülmemiştir. Tedavi grubunda, oksfendazol+oksiklozanid kombinasyonunun etkinliği tedaviden sonraki 14. ve 21. günlerde oldukça yüksek (% 100) bulunmuştur. Öneri: Bu çalışma ile oksfendazol+oksiklozanid kombinasyonunun, çalışma alanındaki koyunların gastrointestinal nematodlarına karşı oldukça etkili olduğu ortaya konulmuştur.
Aim: This study was performed to re-evaluate the efficacy of the combination oxfendazole+oxyclozanide, after thirty years of its introduction into the Turkish antiparasitic drug market. Materials and Methods: In this study, 32 sheep infected with gastrointestinal nematodes were used. Sheep were selected on the basis of the number of eggs in one gram of their fecal sample. Sheep selected were divided into two groups: group I, sheep were treated orally at day zero, with oxfendazole+oxyclozanide combination at a dose rate of 7.5 mg/kg and 15 mg/kg of body weight, respectively; group II, sheep were used as untreated controls. Fecal samples were collected from each sheep on day 1 of their treatment, and on days 7, 14, and 21 of post-treatment. To determine the anthelmintic drug treatment’s efficacy, individual sheep’s fecal egg count per gram of feces was determined by performing McMaster method and fecal egg count reduction test. Results: Fecal egg counts of these two groups were statistically not different on the day of treatment. At day 7 of post-treatment, few eggs were detected only in one sheep, and the mean of fecal egg counts of the treatment group was 66.7 ±66.7. On days 14 and 21 of post-treatment, fecal egg counts decreased to zero in the treatment group but significantly did not change in the control group. The efficacy of the combination was found to be 100% at day 14 and 21 of post-treatment. Conclusion: This study revealed that the combination oxfendazole+oxyclozanide was highly effective against the gastrointestinal nematodes in sheep
