MORIER, LUIS et al. Comparación de la línea NCI-H292 con otras líneas continuas para la multiplicación de virus respiratorios. Rev Cubana Med Trop [online]. 1996, vol.48, n.3, pp.171-173. ISSN 0375-0760.

The NCI-H292 continual line of mucoepidermoid cells of the human lungs has been reported to be useful for the propagation of many viruses, mainly Adenovirus and Paraxymovirus. It is stated the possible substitution of primary cultures of monkey kidney for NCI-H292 in order to isolate such agents. In the present paper it is evaluated the utility of this line for multiplying the respiratory syncytial viruses Adenovirus 3 and 7, and the parainfluenza viruses 1, 2, and 3, in comparison with the continual cellular lines traditionally used for the propagation of these viruses, whose strains were inoculated this time in the Vero, HEp-2, and HeLa lines, according to their know sensitivities as well as in NCI-H292 simultaneously. The viral multiplication was detected by the appareance of the cytopathic effect or by hemaadsorption. As a result, it was demostrated the multiplication capacity of the NCI-H292 line for Adenoviruses 3 and 7 and parainfluenza 3, being more useful for their multiplication than the tradicionally used lines.
