Horizontal transmission of feline leukemia virus under experimental conditions. 1977

E A Hoover, and R G Olsen, and W D Hardy, and J P Schaller

Thirty-seven specific-pathogen-free (SPF) cats ranging from newborn to 1 year were inoculated with the Rickard strain of feline leukemia virus (FeLV). Each inoculated cat shared a cage with a control SPF cat for 40 weeks post inoculation. After 4-5 weeks, 20 of the inoculated cats became group-specific antigen (gsa)-positive; the other 17 remained gsa-negative but developed virus neutralizing and feline oncornavirus cell membrane-associated antigen antibody titers. Seventeen of the control cats in contact with the gsa-positive cats developed evidence of FeLV infection 4-18 weeks after virema was detected in their inoculated cage mates. Of the control cats in contact with inoculated cats that remained gsa-negative, none developed evidence of FeLV infection. Data indicated that the gsa-positive state in cats inoculated with FeLV correlated with the capacity for horizontal transmission of the virus.

D002415 Cats The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D004780 Environment, Controlled A state in which the environs of hospitals, laboratories, domestic and animal housing, work places, spacecraft, and other surroundings are under technological control with regard to air conditioning, heating, lighting, humidity, ventilation, and other ambient features. The concept includes control of atmospheric composition.

D005256 Leukemia Virus, Feline A species of GAMMARETROVIRUS causing leukemia, lymphosarcoma, immune deficiency, or other degenerative diseases in cats.
