ABSTRACT: A cell capsule was revealed by transmission electron microscopy on the surface of non-agglutinating (KG-), but not on agglutinating (KG+), cells of the bacterial fish pathogen Enterococcus seriolicida. The capsule of KG- cells may be involved in resistance to opsonophagocytosis by head kidney phagocytes of yellowtail Seriola quinqueradiata.
