(i) This dataset presents macroscopic and microscopic pathological findings and bacteriology of 178 tadpoles diagnosed with Severe Perkinsea Infections. (ii) Specimen were collected and submitted to the NWHC as part of mortality investigations and collection of specimen from apparently healthy populations as part of ongoing amphibian health monitoring. (iii) Necropsies and gross evaluation of carcasses were carried out under a dissecting microscope. (iv) Severe Perkinsea Infection was confirmed in each specimen by histological observation of pathological changes in tissues with presence of Perkinsea-like organisms in at least one organ, including brain, eyes, gastrointestinal tract, gills, heart, liver, lungs, kidney,...
During 2002−2015 we examined the causes of mortality in beachcast northern sea otters (Enhydra lutris kenyoni) collected from the coasts of Washington and Oregon states. A total of 333 moribund or dead sea otters were reported through opportunistic observations and 93 otter carcasses were collected for necropsy. Retrieved carcasses received a full diagnostic evaluation to determine cause of death when carcass condition permitted. Otter stranding reports were received from the entire Washington coast and northern Oregon coast, but carcasses located near areas populated by humans were most often in suitable condition for cause of death determination. Data in this release include basic demographic information on the...
(i) Severe perkinsea data was based on the observation of characteristic gross and microscopic lesions and the morphological identification of Perkinsea organisms within the lesions. Necropsies and gross evaluation of carcasses were carried out under a dissecting microscope. Specimen were collected and submitted to the NWHC as part of mortality investigations and collection of specimen from apparently healthy populations as part of ongoing amphibian health monitoring. (ii) Epidemiological information was compiled from each anuran sample, including the detection type (mortality event or health monitoring study), location (state and county), anuran species reported in the event, life-stage of species reported in the...
