title: [Electron microscopy of bovine leukosis viruses (BLV) in a fetal lamb spleen cell line].
abstract: The ultra-thin section method, the method of negative staining, and immunoelectron microscopy were used for detecting BLV and for determining its morphological characteristics in the FLS continual cell line used as a virus antigen producer for the ELISA test. Particles of C type, about 110 nm in size, having a structure corresponding to BLV, were detected in the FLS cells on the ultra-thin sections. The viruses were located extracellularly, in cytoplasmic vacuoles, and in different stages of maturation by budding from cell plasma membrane. BLV presence was also demonstrated by immunoelectron microscopy.
