Edwardsiella tarda Isolated from a Kidney Mass in a Common Loon (Gavia immer).

A Common Loon (Gavia immer) was found recumbent at Island Beach State Park, New Jersey, US, and euthanized. Necropsy revealed a caseous mass in the kidney, from which bacteria were isolated and phenotypically and molecularly identified as Edwardsiella tarda.

Myxozoan parasites vary in river herring according to life history stage and habitat.

Anadromous river herring have declined in many parts of their range, leading to fisheries management efforts to help repopulate this species by improving connectivity of rivers and restoring populations by fish transfers. With data lacking on parasites in these species, this study sought to better understand myxozoans across various life stages and habitats in river herring populations in New Jersey, USA. We compared fish from riverine habitats during early-life growth and adults returning to spawn, marine-phase fish, and landlocked Alewife populations.

Seasonal intestinal coccidiosis in wild bluegill Lepomis macrochirus is associated with a spring bacterial epizootic.

Wild bluegill, Lepomis macrochirus Rafinesque, succumb to seasonal mortality in the early spring during cool water temperatures, shown previously to be related to bacteraemia caused by a psychrotrophic bacterium, Pseudomonas mandelii. In the study herein, intestinal coccidiosis in wild bluegill had seasonal prevalence causing heavy intestinal infections and sloughing of intestinal epithelium occurring in late winter/early spring. Infections were predominantly related to two different species, Goussia washuti n.
