Necropsy of a young manatee from the west coast of Florida revealed an active infection of the umbilical area (omphalitis) extending down the umbilical artery and veins. A generalized peritonitis was present. Bacterial cultures revealed Streptococcus faecium, Plesiomonas shigelloides, Pseudomonas putrefaciens and Escherichia coli.
