The carcinomas deriving from the papillomas induced with a virus in domestic rabbits (1) have this virus as their primary cause. The present paper is concerned with the carcinogenic effect of various strains of the virus,--meaning thereby the infective materials procured from the "spontaneous" papillomas of different cottontail rabbits,--and with the influence of the concentration of the inocul...

Tularemia, also called Ohara’s disease, is an acute bacterial infectious disease caused by a pleomorphic, non-mobile, non-capsulated, small Gram negative coccobacillus and zoonotic bacterium, Francisella tularensis. This zoonotic bacteria has reportedly infected a wide range of wild animals (rabbits, hares, squirrels, muskrats, moles, skunks, beavers, deer), some domestic animals (sheep, cattle...

Coccidiosis is a challenging disease of wild and domestic rabbits both, caused by Eimeria and thereby leads enormous economic losses at rabbit farms. The present study carried out to survey the prevalence and intensity of coccidial infection among the rabbits in Sichuan Province, southwest China. A total of 110 faecal samples were collected from 11 farms situated in eight main rabbits rearing a...

Abstract This study investigated the effect of oleo-gum-resin from Commiphora molmol Engler (Family: Burseraceae), commonly known as myrrh and as the commercial extract Mirazid, as a treatment for hepatic coccidiosis induced by the parasite Eimeria stiedae in domestic rabbits. Rabbits (Oryctolagus domesticus L.) were infected with sporulated parasite oocysts and subjected to treatment regimens ...

A change in the type of lesion produced by the fibroma virus has been observed. At about its 18th serial transfer in domestic rabbits the virus lost its ability to induce fibromas when administered subcutaneously. Instead, lesions developing in either the subcutaneous tissue or in the testicle were predominantly inflammatory in character and partly composed of lymphocytes and large mononuclear ...

In this survey we examined 87 domestic animal stool samples in order to detect the possible presence of microsporidia in animals in close contact with humans in Galicia (NW, Spain). The detection of Enterocytozoon bieneusi spores was confirmed in faecal samples from two dogs and one goat by polymerase chain reaction. None of the positive samples for microsporidia in the staining method were amp...

Microsporidia are ubiquitous parasites infecting all animal phyla and we present evidence that supports their zoonotic potential. Fecal samples taken from domestic (cats and dogs), farm (pigs, rabbits and ostriches) and wild animals (foxes) from different provinces of Spain were evaluated for microsporidia infection by light microscopy and PCR. After Microsporidia species identification, E. bie...

Cottontail rabbit papillomavirus induces benign tumors, papillomas, in rabbits which progress at a high frequency to malignant tumors, carcinomas. Cottontail rabbit papillomavirus therefore provides an experimental model for oncogenic human papillomaviruses. The nature of the antigens recognized by the host has not been identified at any stage of tumor development. Here, we characterized the hu...

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...
