Unless, of course, one of these exceptions apply:

http://wiki.creativecommons.org/FAQ#Do_Creative_Commons_licenses_affect_exceptions_and_limitations_to_copyright.2C_such_as_fair_dealing_and_fair_use.3F

whether using a single slide out of 50 would be considered "fair use" would
depend on how central the slide was too the original presentation, the
intended use of the new presentation, and perhaps some other factors, but
I'd guess that more often than not it would qualify for a fair use
exception.
