The aim of present studies was the structural and morphogenetic investigation of spontaneous pneumoenteritis syndrome in newborn and growing calves with regard to confirmation of some structural features of disease morphogenesis. The research was done with 370 calves from 6 cattle farms in 4 regions of the country, at the age of 24 h - 25 days. For rapid antigenic and viral detection of pathogens, Multiscreen Ag ELISA, Bovine respiratory, Pulmotest respiratory tetra ELISA kit for antigenic diagnosis of BoНV-1, BVDV, BRSV, and BPI-3 sandwich test for tissue lysates (BIOX Diagnostics, Belgium) and Rainbow calf scour 5 BIO K 306 Detection of Bovine Rotavirus, Coronavirus, Escherichia coli F5, Cryptosporidium parvum and Clostridium perfringens in bovine stool (BIOX Diagnostics, Belgium) were used. In 5% of cases, laboratory antigenic tests of lung tissue lysates from pneumonic calves detected co-infections with BoНV-1, BVDV, BRSV and BPI-3. The utilised antigenic, ultrastructural and virological diagnostic methods allowed concluding that they could be successfully used in the diagnostics of pulmonary and gastrointestinal viral infections in juvenile calves. Electron microscopy and immunohistochemical methods of lung and intestinal tissue are also important and applicable for diagnostics and in differential diagnostic recognition of the condition from other common diseases as IBR, BVD, BRSV, Mannheimia haemolytica, Cryptosporidium parvum, BRV and E. coli K99 (F5).
Bu çalışmanın amacı spontan pnömoenteritis sendromlu yeni doğan ve büyüme dönemindeki buzağılarda hastalığın morfogenezine yönelik bazı yapısal özellikleri incelemektir. Çalışma ülkenin 4 bölgesinden 6 çiftlikte toplam 370 adet 24 saatlik ile 25 günlük arasındaki buzağı üzerinde gerçekleştirildi. BoНV-1, BVDV, BRSV ve BPI-3’ün hızlı tespiti amacıyla Multiscreen Ag ELISA Bovine respiratory, Pulmotest respiratory tetra ELISA kit kullanıldı (BIOX Diagnostics, Belçika). Sığır dışkısında Rotavirus, Coronavirus, Escherichia coli F5, Cryptosporidium parvum ve Clostridium perfringens tespiti amacıyla Rainbow calf scour 5 BIO K 306 kullanıldı (BIOX Diagnostics, Belçika). Vakaların %5’inde BoНV-1, BVDV, BRSV ve BPI-3 pnömonili buzağıların akciğer doku lizatlarında birlikte gözlemlendi. Çalışmada kullanılan antijenik, ultrastrüktürel ve virolojik tanı metotlarının başarılı bir şekilde pulmoner ve gastrointestinal viral enfeksiyonların tespitinde kullanılabileceği belirlendi. Akciğer ve barsak dokularında elektron mikroskopi ve immunohistokimyasal metotlar tanıda uygulanabilir olup IBR, BVD, BRSV, Mannheimia haemolytica, C. parvum, BRV ve E. coli K99 (F5) gibi diğer yaygın hastalıklardan ayırıcı tanıda önemlidirler.
