Emergent multisystemic Enterococcus infection threatens endangered Christmas Island reptile populations.

摘要: Multisystemic infections with a morphologically unusual bacterium were first observed in captive critically endangered Lister's geckos (Lepidodactylus listeri) on Christmas Island October 2014. Since then the infection was identified another lizard species, blue-tailed skink (Cryptoblepharus egeriae) and two species of invasive geckos; four clawed gecko (Gehyra mutilata) Asian house (Hemidactylus frenatus), wide geographic range across east side island. The Gram periodic acid-Schiff positive cocci to diplococci have propensity form chains surrounded by matrix, which ultrastructurally appears be formed fibrillar capsular projections. associated severe extensive replacement tissues, but minimal host inflammatory response. Attempts grow organism culture embryonated eggs unsuccessful. Molecular characterisation placed it as novel member genus Enterococcus. Disease Risk Analyses including this should now factored into conservation management actions island biosecurity.
