Bu çalışmanın amacı Kırıkkale ve Ankara yöresinde yetiştiriciliği yapılan evcil tavşanlarda sindirim sistemi parazitlerinin yaygınlığının araştırılmasıdır. Çalışma sırasında 100 adet tavşan kafesinden dışkı örnekleri alınmıştır. Her kafesten alınan dışkılar kafes içerisindeki sayısına bakılmaksızın tek örnek olarak değerlendirilmiştir. Alınan örnekler Fülleborn flotasyon tekniği ile incelenmişt...

In 1933, Shope (14) described a virus-induced papilloma occurring naturally in the cottontailS rabbit (genus Sylvilagus) and transmissible to the domestic rabbit (genus Oryctolagus). Later, Rous and Beard (13) found that the experimentally in duced papillomas in domestic rabbits often pro gressed to carcinomas; and Syverton and Berry (16,17)observedthesamephenomenon incotton tail rabbits. Becau...

The Shope papilloma virus elicits carcinomas forthwith, as well as papillomas in great variety, when it is distributed by way of the blood stream to the tarred epidermis of domestic rabbits. The phenomenon will be analyzed in succeeding papers with the aid of additional instances.

Virus-induced papillomas (Shope) on domestic rabbits are susceptible to Roentgen rays. The dosage which uniformly brings about their complete and permanent disappearance has been found to be 3600 r (200 kilovolts), whether this dose be administered at one time or fractionally. 60 per cent of the tumors are cured when irradiated with 3000 r.

Rabbit Haemorrhagic Disease Virus (RHDV) is of worldwide significance for both, domestic and wild rabbits (Oryctolagus cuniculus). While the loss of natural populations of wild rabbits in south-western Europe is of major conservation concern because rabbits are a key-stone species in natural ecosystems, the virus has been successfully used as a biological control of pest rabbits in Australia. H...

We previously reported the partial characterization of two cottontail rabbit papillomavirus (CRPV) subtypes with strikingly divergent E6 and E7 oncoproteins. We report now the complete nucleotide sequences of these subtypes, referred to as CRPVa4 (7,868 nucleotides) and CRPVb (7,867 nucleotides). The CRPVa4 and CRPVb genomes differed at 238 (3%) nucleotide positions, whereas CRPVa4 and the prot...
