Abstract

Blue Tongue vaccine was prepared at Foot and Mouth Disease Serology and Tissue Culture Laboratory of Etlik Baderiology Institute· Ankara, for experimental study. To prepare the vaccine 14 of several strains of the virus were brought from Mexico. Mossap strain which had been suitably attenuated by 60 serial passages in embryonating chicken eggs was used in this study. Fertile eggs, preincubated for 8 days, were inoculated with 0,2 ml of 1/ 10 dilution of Mossap strain via yolk sac route. Death of embryos duringthe first 48 hours after inoculation, were discarded. Observation continued for 5 days. The contents of the eggs of embryos which haddiedwithin 3th. to 5th. days postinoculation, were collected. The contents of the eggs were mixed with equal volume of Buffer- Lactose- Pepton medium, 100 units of penicilline and 100 microgram streptomycin per milliter were also added. The mixture was dispensed in 0,75 ml quantities into each ampule and desiccated in Freeze- Dryer- appartus. The titration of the vaccine examined by the method of Reed and Muench before and after desication. It was calcullated that the titration before desiccation was 10 -6,2 after desiccation was 10 -5,6

Özet

Tecrübevi çalışma maksadı ile Ankara- Etlik Bakteriyoloji Enstitüsü Şap Seroloji ve Doku Kültürü Laboratuvarında mavi dil aşısı hazırlanmıştır. Aşının hazırlanması için 14 çeşitli suç Meksikadan getirtilmiştir. Bu çalışmada 60 pasajla yumurta embriyosuna adapte edilmiş Mossap suşu kullanılmıştır. 8 günlük embriyonl uyumurta sarısına (BTV) Mossap suşunun 1/10 dilusyonundan 0,2 cc. inakule edilmiştir. İnokulasyondan sonra 48 saat zarfında ölenler nazarı itibare alınmamıştır. Müşahade inakulasyondan sonra 5 gün devam etmiştir. İnokulasyondan sonra 3 - 5 gün içinde ölen yumurtaların muhtevisi toplanmıştır. Bu yumurta muhtevası aynı miktar Buffer- Laktoz- Pepton vasatı ile karıştırılmıştır. Herbir cc. için 100 ünite penicilline ve 100 mikrogram streptomycin ilave edilmiştir. Bu karışım 0,75 cc. miktarında ampullere taksim edilmiş ve freeze- dryer'de kurutulmuştur. Aşı titrasyonu Reed ve Muench metoduna göre kurutulmadan evvel ve sonra olmak üzere iki defa yapılmıştır. Kurutmadan evvelki titrasyona 10 -6,2 kurutmadan sonraki titrasyon 10 -5,6 olarak tesbit edilmiştir. Aşının muafiyet denemeleri henüz yapılmamıştır.
