TABLE 1.

Protein profiles of wild-type and cytadherence mutant M. pneumoniae

M. pneu- moniae	Proteina						Reference
	HMW1	HMW2	HMW3	P30	P30 Δb	P65
Wild type	++++	++++	++++	++++	−	++++	20, 23
Mutant I-2	+	−	++	+++	−	++	20
Mutant M6	−	+	++	−	++	+	17, 22
Mutant II-7	++++	++++	++++	−	++	+	8, 17, 20

^aSymbols indicate relative amounts of each protein ranging from − (none) to ++++ (wild type).

^bMutants M6 and II-7 have an internal, in-frame deletion in the gene encoding P30, resulting in an identical truncated P30, designated P30 Δ.
