title: [Detection of common antigenic determinants in the envelopes of mammalian type D (Mason--Pfizer) and type C virions by using the virion precipitation reaction].
abstract: Immune sera to Mason-Pfizer virus (M-PMV) are capable of precipitating type C viruses of mice (NIH-MuLV, G-MuLV, and to a lower degree R-MuLV), cats  (FeLV, RD-114), and monkeys (SSV-1, GALV, BEV). The immune sera to RD-114, BEV, SSV-1 and GALV viruses can precipitate M-PMV virions. The adsorption analysis suggests that cross-reactions between M-PMV, RD-114, NIH-MuLV, and G-MuLV viruses depend on common virus-specific antigenic determinants in the envelopes of the virions. The relationship between M-PMV and type C viruses decreases in the series RD-114--NIG-MuLV--G-MuLV. Type C viruses of mammals have common envelope antigenic determinants lacking in M-PMV. No common antigenic determinants with M-PMV have been found in the envelope of virions of bovine leukemia virus, type B virus of mice (MMTV), or type C avian virus (Pr-RSV).
