Comparative clinico-morphological investigations of the CNS of monkeys and of the eye teguments of guinea pigs infected with different measles virus strains.

Measles virus strains Edmonston and L-16 have been studied in 10 intracerebrally (i.c.) infected monkeys and in 155 guinea pigs infected into the anterior eye chamber.

[Study of viral contamination of Japanese quail and cell cultures from their embryos].

Agents identified as adenovirus CELO were isolated from organ suspensions of 1500 Japanese quails (JQ) in 4 experiments. No contaminating viruses were found in examinations of cell cultures prepared from the kidneys of 80 JQ. Negative results were obtained in examinations of 163 antigens from JQ organs in the COFAL test.

["Pharaoh" line culture of Japanese quail cells as a leukosis-free system for virus reproduction].

Contamination of Japanese quail, strain Pharaoh, cell culture with oncogenous and infectious avian viruses was studied. The susceptibility of the embryonal cell cultures of the Japanese quail, strain Pharaoh, to measles, parotitis and fixed rabies viruses was also determined. It was found that the sera of pubertal quails had no antibody to Rous sarcoma virus (RSV), strains Brian, RSV (RAV-1), Schmidt-Ruppin, Carr-Zilber, as well as to Marek's disease and Newcastle disease viruses.
