Table 3. GAS antigens preferentially reacting against tic sera.

SPy	Annotation	Tic	Phar ^(a)	No Tic
SPy0453	metal binding protein of ABC transporter	41	25	9
SPy1939	hypothetical protein	39	13	11
SPy1795	putative ABC transporter	38	22	3
SPy1054	putative collagen-like protein	36	14	3
SPy1306	maltose/maltodextrin-binding protein	34	15	0

Numeric values refer to % of positive sera of each class versus each antigen.

Number of tic, pharyngitis and no tic sera positive against each antigen were compared using two-tailed χ² test, resulting in a statistically higher number of positive tic sera as compared to pharyngitis and no tic sera (P<0.05).
