Molecular Analysis of Vancomycin-Resistant Enterococci Isolated from Regional Hospitals in Trinidad and Tobago

Table 1

Showing various pulsed-field gel electrophoresis (PFGE) groups of 45 vancomycin-resistant enterococcal isolates from regional hospitals in Trinidad and Tobago (%).

Source		E. faecium					E. faecalis
		PFGE-1	PFGE-2	PFGE-3	PFGE-4	PFGE-5	PFGE
UGT	17 (38)	4	1	6	2	4	7
SSTI	19 (42)	6	4	5	0	4	0
Blood	1	0	1	0	0	0	0
GIT	1	1	0	0	0	0	0
Total	38	11 (29)	6 (16)	11 (29)	2 (5)	8 (21)	7

= number of isolates distribution; PFGE = pulsed-field gel electrophoresis pattern signifying the same clone; UGT = urogenital tract; SSTI = skin and soft tissue infections; GIT = gastrointestinal tract, and this sole isolate was from the peritoneal fluid of a patient who had peritonitis. All seven vancomycin-resistant E. faecalis had an identical PFGE pattern indicating they belong to the same clone.
