Challenging Host Specificity: Malacosporean Parasite Dynamics—Tetracapsuloides bryosalmonae Beyond Salmonids—An Infection Experiment

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Proliferative Kidney Disease (PKD) is a severe parasitic disease of salmonids caused by the malacosporean endoparasite Tetracapsuloides bryosalmonae. In the fish intermediate host, the parasite is disseminated via the circulatory system and ultimately reaches the kidney, where it matures before releasing infective spores into the environment ...

Lymphocystis Disease in Endemic Aotearoa New Zealand Bully (Gobiomorphus cotidianus)

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT We detected lymphocystis disease virus (LCDV) for the first time in an Aotearoa New Zealand freshwater environment, from an individual common bully, toitoi, Gobiomorphus cotidianus (Eleotridae). Dinah's bully, Gobiomorphus dinae, and Kaharore bully, Gobiomorphus mataraerore, also exhibited gross nodular lesions on the fins but were not sampled.
