Schuster C, Murray K, Sanders J, Couch C, Kent M
J Eukaryot Microbiol . 2024 Jul; 71(5):e13040. PMID: 38961716
Zebrafish (Danio rerio) is now the second most used animal model in biomedical research. As with other vertebrate models, underlying diseases and infections often impact research. Beyond mortality and morbidity,...

Tsuchida D, Gentzkow M, Spaan R, Burco J, Couch C, Spaan J, et al.
J Wildl Dis . 2024 Apr; 60(3):721-726. PMID: 38659241
Bighorn sheep (Ovis canadensis) are herbivorous ungulates that live in forage-poor areas of the American west. The trace minerals that herbivores derive from forage are important for immune function. Therefore,...

Couch C, Neal W, Herron C, Kent M, Schreck C, Peterson J
Sci Rep . 2023 Feb; 13(1):2567. PMID: 36782001
Pacific salmon experience prolonged elevation in corticosteroid hormones during important life history events including migration, reproduction, and senescence. These periods of elevated corticosteroids correspond with changes to immunity and energy...

Couch C, Kent M, Weiss L, Takvorian P, Nervino S, Cummins L, et al.
mSphere . 2022 Jan; 7(1):e0090821. PMID: 34986317
A novel infection was identified in the intestines of sexually mature Chinook salmon. While microsporidian parasites are common across a diverse range of animal hosts, this novel species is remarkable...

Couch C, Epps C
J Hered . 2022 Jan; 113(3):221-234. PMID: 34983061
In recent years, emerging sequencing technologies and computational tools have driven a tidal wave of research on host-associated microbiomes, particularly the gut microbiome. These studies demonstrate numerous connections between the...

Rothenberg S, Sweitzer D, Rackerby B, Couch C, Cohen L, Broughton H, et al.
Front Microbiol . 2021 Jun; 12:648685. PMID: 34177830
Objectives: Methylmercury metabolism was investigated in Pacific walruses () from St. Lawrence Island, Alaska, United States. Methods: Total mercury and methylmercury concentrations were measured in fecal samples and paired colon...

Couch C, Stagaman K, Spaan R, Combrink H, Sharpton T, Beechler B, et al.
Nat Commun . 2021 Apr; 12(1):2267. PMID: 33859184
Studies in humans and laboratory animals link stable gut microbiome "enterotypes" with long-term diet and host health. Understanding how this paradigm manifests in wild herbivores could provide a mechanistic explanation...

Couch C, Wise B, Scurlock B, Rogerson J, Fuda R, Cole E, et al.
PLoS One . 2021 Apr; 16(4):e0249521. PMID: 33831062
Supplemental feeding of wildlife is a common practice often undertaken for recreational or management purposes, but it may have unintended consequences for animal health. Understanding cryptic effects of diet supplementation...

Yang C, Kari L, Lei L, Carlson J, Ma L, Couch C, et al.
mBio . 2020 Aug; 11(4). PMID: 32817110
is an obligate intracellular bacterial pathogen that causes blinding trachoma and sexually transmitted disease afflicting hundreds of millions of people globally. A fundamental but poorly understood pathophysiological characteristic of chlamydial...

Sci Rep . 2020 Apr; 10(1):6582. PMID: 32313214
Studies in laboratory animals demonstrate important relationships between environment, host traits, and microbiome composition. However, host-microbiome relationships in natural systems are understudied. Here, we investigate metapopulation-scale microbiome variation in a...
