| - Viry leukózo-sarkomového komplexu jsou častými původci nádorových onemocněníu drůbeže. Cílem této studie bylo zjistit četnost výskytu nádorů a prevalenci protilátek protileukózo-sarkomovým virům podskupiny A a B u nosnic kura domácího (Gallus gallus f.domestica) rodičovských a užitkových chovů v České republice. Přiítomnost nádorů bylasledována na porážkách u celkem 91 chovů nosnic a bylo zjištěno, že prevalence nádorových změn je nízká. Nádory se vyskytly v 82 chovech (90,1 %), ale v 62 chovech (68,1 %) incidence nepřekročila půl procenta a pouze ve 3 chovech (3,3 %) byla vyšší než jedno procento. V 9 chovech (9,9 %) se nádory nevyskytovaly vůbec. Pro zjištění spektra vyskytujících se nádorů bylo histopatologicky vyšetřieno 14 náhodně odebraných vzorků.Nádory vyšetřené u nosnic na konci snášky byly histogeneticky pestré. Zahrnovaly pětadenokarcinomů pankreatu, třii adenokarcinomy vejcovodu, dva leiomyomy závěsuvejcovodu, po jednom adenokarcinom vaječníku a lymfom střieva. Byly zaznamenány i dva přípa (cs)
- Viruses belonging to the leukosis/sarcoma group represent a frequent cause of neoplasm inpoultry. The aim of this study was to assess the frequency of tumours and the prevalence ofantibodies against leukosis/sarcoma viruses from subgroups A and B in laying hens of domesticfowl (Gallus gallus f. domestica), both in parents and production flocks from the Czech Republic.A total of 91 flocks of laying hens from three different slaughterhouses were examined for thepresence of tumours. The occurrence of neoplastic lesions was found to be low. Although tumoursoccurred in 82 flocks (90.1%), their incidence in 62 (68.1%) flocks was below 0.5%, and it onlyexceeded one percent in 3 flocks (3.3%). 9 flocks (9.9%) had no tumours. In order to determine thespectrum of the tumours, 14 randomly collected samples were histologically examined. Thetumours found in hens at the end of the laying period showed varied histogenesis (five cases ofpancreatic adenocarcinoma, three cases of adenocarcinoma of the oviduct, two case
