Proportion of opportunistic enteric bacterial pathogens in sea otter feces using selective media.

Bacterial species	All sampled otters (%)	Prevalence, live otters^a (%)	Prevalence, dead otters^b (%)
C. perfringens	27.5	13	46
V. parahemolyticus	19.3	18	21
V. alginolyticus	17.3	23	10
Campylobacter spp.	6.5	3	11
C. difficile	6.0	4	8
P. shigelloides	5.3	4	7
Other Vibrio spp.	4.8	7	2
V. cholerae	2.5	2	3
Salmonella spp.	1.4	1	2
V. fluvialis	0.6	1	0
E. coli O157:H7	0	0	0

n = 137 live southern sea otters, except for C. difficile and V. cholerae, where n = 96 otters.

n = 107 fresh dead sea otters, except for C. difficile and V. cholerae, where n = 98 otters.
