Correlation between PFGE Groups and mrp/epf/sly Genotypes of Human Streptococcus suis Serotype 2 in Northern Thailand

Table 1

Correlation between PFGE groups and mrp-epf-sly genotypes of S. suis serotype 2 isolated from 62 patients and 4 healthy pigs.

PFGE groups (number found)	mrp-epf-sly genotypes (number found)	Patient isolates; (% found)	Healthy pig isolates; (% found)
A (44)	mrp ^+epf ^−sly ^−  (44)	43 (69.4)	1 (25)
B (2)	mrp ^+epf ^−sly ^−  (2)	2 (3.2)	0
C (4)	mrp ^+epf ^+/epf*sly ^+  (4)	4 (6.4)	0
D (12)	mrp ^−epf ^−sly ^+  (11)	8 (12.9)	3 (75)
	mrp ^+epf ^−sly ^−  (1)	1 (1.6)	0
E (4)	mrp ^+epf ^−sly ^−  (4)	4 (6.4)	0

𝑒𝑝𝑓^∗: When used the same primer with the epf gene for PCR detection, the amplified fragment of this gene was approximately 1,278–3,000 bp.
