2011 and 2017 Pika Pathology Colorado American pikas (Ochotona princeps) are small lagomorphs that live in mountainous talus areas of western North America. Studies on the histopathology of American pikas are limited. This report summarizes the clinical histories, and gross and histologic findings of 12 American pikas, including nine captive and three wild animals. Death was often attributed to stress (transport, handling, and anesthesia) with few to no premonitory clinical signs. Two cases died due to infection: one had bacterial pyogranulomatous dermatitis, cellulitis, and lymphadenitis with sepsis; the other case had fungal necrotizing colitis. Incidental parasite infections included sarcocystosis, nematodiasis (oxyurids), and ectoparasitism. Most...

Yet, aside from Ophidiomyces ophidiicola, little is known about other mycoses affecting wild reptiles. The closely related genus Paranannizziopsis has been associated with dermatomycosis in snakes and tuataras in captive collections and P. australasiensis was recently identified as the cause of skin infections in non-native wild panther chameleons (Furcifer pardalis) in Florida, USA. Here we describe five cases of Paranannizziopsis spp. associated with skin lesions in wild snakes in North America and one additional case from a captive snake...

Most recently, many authorities treat M. occultus as a distinct species, at least in part because a previous study showed that M. occultus and M. l. carissima (the subspecies that occurs in closest proximity to M. occultus) form separate monophyletic clades based on sequences of two mitochondrial genes (cytochrome-b [cytb] and cytochrome oxidase subunit II [COII]). We re-evaluated the phylogenetic relationship between M. occultus and M. lucifugus based on mitochondrial sequences using an expanded dataset of cytb and COII sequences that originated from more genetically diverse specimens of M. lucifugus collected across...

At capture, in addition to age, sex, body weight of the hare and a blood sample data was collected on the ecological land type (USDA Forest Service. 2006. Hiawatha National Forest 2006 Forest Plan. https://www.fs.usda.gov/detail/hiawatha/landmanagement/planning/?cid=STELPRDB5106336) at the point of capture.

A total of 2453 serum samples were collected from wild birds. We tested all samples by enzyme-linked immunosorbent assay (ELISA) for evidence of previous exposure to avian influenza virus with 1302 testing positive.

This need is particularly acute given that disease is emerging as a major factor in declines of ecologically important functional groups such as corals. Here we describe a simple method to process cnidarian cells for microscopic examination using the model organism Aiptasia. We show that this organism has at least 18 cell types or structures that can be readily distinguished based on defined morphological features. Some of these cells can be related back to anatomic features of the animal both at the light microscope and ultrastructural level....

This data was collected in the field by students and sent to the USGS National Wildlife Health Center (NWHC) for testing of two amphibian fungal pathogens, Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bs). The dataset includes both the field records of the individual amphibians tested and the results for individuals for Bd and Bs. This is Product Number 209311 of the U.S. Geological Survey Amphibian Research and Monitoring Initiative (ARMI).

Sequences were generated from metacercariae samples at U.S. Geological Survey National Wildlife Health Center (NWHC) and compared for base pair similarities with publicly available sequences from GenBank using BLAST (https://blast.ncbi.nlm.nih.gov/Blast.cgi). Selection of GenBank sequences to include in the .msf file was based on the number of base pair similarities (94% or higher identity to this study’s sequences), 98–100% coverage AND stage of parasite from which the sequence was generated. An excel file listing all parasites and DNA from NWHC vouchered with the University...

More than 14,000 dead seabirds were reported and a total of 117 carcasses were examined. 92 cases had emaciation identified as the Cause Of Death (COD), seven cases where COD was undetermined, and 17 cases where COD was determined as "Other", which included predation, trauma, encephalitis, peritonitis, and bacterial infection. Low Pathogenic Avian Influenza (n=4) and saxitoxin (n=15) were also detected; however, the virus and biotoxin were not determined to be the COD except for one case in 2020 where saxitoxin toxicosis was suspected.

An interagency One Health response was initiated to assess the extent of the outbreak and included sampling animals from or near affected mink farms and testing them for SARS-CoV-2 and non-SARS coronaviruses. Among the 365 animals sampled, including domestic cats, mink, rodents, raccoons, and skunks, 261 (72%) of the animals harbored at least one coronavirus at the time. Among the samples which could be further characterized, 126 alphacoronaviruses and 88 betacoronaviruses (including 74 detections of SARS-CoV-2) were identified. Moreover, at least 10% (n=27) of the corona-virus-positive animals were found to be co-infected with more than one coronavirus....
