Virus isolation and titration at 33‡ and 37‡ C	1975		.txt	text/plain	1157	81	52	Various prototype viruses and original specimens were comparatively titrated in cell cultures at 33‡ and 37‡ C. g. Lennette and Schmidt, 1969) recommend an incubation temperature of 33 ~ rather than 37~ for the isolation of viruses from the human respiratory tract. Original specimens (stool suspensions, throat and conjunetival swabs, vesicular fluid) containing the following virus types were inoculated: adenovirus I, 2, 3, 5, 7, 8, herpesvirus hominis, poliovirus 1 and 3, coxsackievirus A9 and B5, eehovirus types 6, 9, 11, 18 and 30. To our knowledge influenza viruses are the only ones of the viruses occurring in the human respiratory tract, in which a comparative testing of original specimens (in embryonated eggs) has demonstrated the superiority of the lower temperature (Stern and Tippett, 1963) . Both temperatures appear satisfactory for vaccinia virus, herpesvirus, enteroviruses and parainfluenza viruses.	./cache/cord-004761-cgby8bhz.txt	./txt/cord-004761-cgby8bhz.txt
