摘要: Abstract From April to September in 2010, a sequential epidemic outbreak with loss of 30–40% occurred tilapia fishery Maoming, Guangdong Province, China. The present study documented the causative agent diseased fish that mainly suffered from congestive gill and abdomen, swelling gallbladder severe diffusion liver. Two isolates were obtained pathogenicity was confirmed by challenge experiments histopathological analysis. Biochemically, showed properties biochemical characteristics both identical Aerococcus viridans . Sequencing 16S rRNA genes revealed two highly homogeneous A Consequently, they as on basis phenotypic characteristics, phylogenetic analysis sequences gene. This work firstly reports infection changes tilapia.
