Sialyltransferase and sialidase specific activities in P. multocida

Strain	Source	Sialyltransferase (pmol/mg of protein)a	Sialidase (RFU/mg of protein)b at:
			pH 8.0	pH 6.8
Cincy	Human	413 ± 51*	700	1,600
Pm70	Avian	133 ± 29	1,200	1,800
Pm70A	Avian	159 ± 37	2,800	ND
TF5	Bovine	397 ± 50*	500	900

^a*, Activity higher than avian strains (see Materials and Methods for a description of the statistical method).

^bND, not done; RFU, relative fluorescence units.
