Cerebellar Hypoplasia Associated with an Avian Leukosis Virus Inducing Fowl Glioma

Avian Leukosis Virus

Ultrastructural studies of chick embryo cells morphological ly altered by strain MC29 avian leukosis virus revealed marked and characteristic differences from normal cells and cells al tered by infection with other avian tumor viruses. Such differ ences were manifest in part in the cytoplasm by high content of free ribosomes, poorly developed rough endoplasmic reticu lum, frequent fat droplets,...

Fowl Paralysis and Other Forms of the Avian Leukosis Complex

The disease called fowl paralysis, together with several other allied conditions classed together as the avian leukosis complex,^ causes a tremendous loss to the poultry industry. The paralysis form of this disease complex was first recognized in the United States along the eastern coast about 1920. During the last 20 years the avian leukosis complex has spread rapidly until few flocks of chick...

Studies on Fowl Leukosis

Following the observations on high-speed centrifugation of the avian sarcoma agent by various investigators,1' 8,10,11,12 similar studies of the agent of fowl leukosis have been undertaken. Since the neoplastic nature of this disease is now rather generally recognized, observations on the filterable agent of chicken leukosis have assumed new significance for the study of the etiology of fowl ne...

The Fowl Leukosis Complex

(Continued from page 31) this pathological cycle is to raise the blood oestrogen level to that stage at which the corpus luteum regresses. This can be done by injecting 25 mg. of stilboestrol dipropionate and potentiating the uterus into rhythmic contractions by injecting posterior lobe pituitary. A similar treatment may be used in case of pyometra. (Brownlee, G. (Wellcome Physiol. Res. Lab., B...
