tests with a temperature-sensitive ( ts ) mutant of hsv-1 ( tsa1 ) defective in glycoprotein synthesis at the nonpermissive temperature ( 39 degrees c ) demonstrated that over 90 % of mutant-infected cells maintained at 39 degrees c and treated with antibody and complement were not lysed , presumably due to the absence of viral glycoproteins on the surface of infected cells at this temperature .
