Intraspecific Variation of Edwardsiella anguillarum From Non‐Anguillid Fish From Varied Geographic OriginsNARA Subscribed
Edwardsiella anguillarum is a gram‐negative bacterium, synonymous with previously described atypical, fish‐pathogenic Edwardsiella tarda . Originally described from eels in 2015, E. anguillarum is an important global fish pathogen, particularly in tilapia. This study describes intraspecific phenotypic and genotypic variability among 17 E. anguillarum isolates from non‐anguillid fish hosts and varied geographic origins. Isolate...
Evidence for Widespread Inter‐Basin Vicariance of Fishes Associated With Quiescent Geologic Features in the Southeastern United StatesNARA Subscribed
Aim Stream captures are implicated as drivers of speciation in many groups of lotic fishes. In the southeastern United States, numerous stream‐dwelling animals possess restricted trans‐divide populations at localities where quiescent geologic features intersect drainage divides, suggesting potential evidence for inter‐basin vicariance via stream capture. However, there has not yet been a comprehensive quantitative biogeographi...
Streptococcus dysgalactiae From Farm‐Raised Channel Catfish in Mississippi, USA, With Notes on Fish‐Associated Group C S. dysgalactiaeNARA Subscribed
Lancefield serological group C Streptococcus dysgalactiae (GCSD) is an emerging cause of fish disease worldwide, largely associated with mariculture in Asia. In the United States (US), GCSD had been a pathogen of minimal concern for fish, but recent cases indicate a putative emergence in wild and cultured freshwater fish populations in the Americas. The current study discusses three novel cases of GCSD‐associated streptococcos...
Enteric septicemia of catfish (ESC), caused by the gram‐negative enteric bacteria Edwardsiella ictaluri , is a significant threat to catfish aquaculture in the southeastern United States. Antibiotic intervention can reduce mortality; however, antibiotic use results in an imbalance, or dysbiosis, of the gut microbiota, which may increase susceptibility of otherwise healthy fish to enteric infections. Herein, recovery of the int...
Embryonic development is a continuum in vivo . Transcriptional analysis can separate established human embryonic stem cells (hESC) into at least four distinct developmental pluripotent stages, two naïve and two primed, early and late relative to the intact epiblast. In this study we primarily show that exposure of frozen human blastocysts to an inhibitor of checkpoint kinase 1 (CHK1) upon thaw greatly enhances establishment of...
In the mid‐2010s, Edwardsiella tarda was reaffiliated into three discrete taxa ( E. anguillarum , E. piscicida , and E. tarda ), obscuring previous descriptions of E. tarda ‐induced pathology in fish. To clarify ambiguity regarding the pathology of E. tarda , E. piscicida , and E. anguillarum infections in US farm‐raised catfish, channel catfish ( Ictalurus punctatus ), blue catfish ( I. furcatus ), and channel × blue catfish...
The bacterium Edwardsiella piscicida causes significant losses in global aquaculture, particularly channel ( Ictalurus punctatus ) × blue ( I . furcatus ) hybrid catfish cultured in the south‐eastern United States. Emergence of E . piscicida in hybrid catfish is worrisome given current industry trends towards increased hybrid production. The project objectives were to assess intraspecific genetic variability of E . piscicida i...
The ENIGMA sports injury working group:– an international collaboration to further our understanding of sport-related brain injuryNARA Subscribed
Sport-related brain injury is very common, and the potential long-term effects include a wide range of neurological and psychiatric symptoms, and potentially neurodegeneration. Around the globe, researchers are conducting neuroimaging studies on primarily homogenous samples of athletes. However, neuroimaging studies are expensive and time consuming, and thus current findings from studies of sport-related brain injury are often...
Extended phenotypes on coral reefs: cryptic phenotypes modulate coral‐vermetid interactionsNARA Subscribed
Phenotypic variation can lead to variation in the strength and outcome of species interactions. Variation in phenotypic traits can arise due to plastic responses to environmental stimuli, underlying genetic variation, or both, and may reflect differences in the focal organism or aspects of the extended phenotype (e.g., associated microbes). We used a reciprocal transplant experiment of Porites corals to evaluate the role of pl...
Edwardsiella ictaluri infection in Pangasius catfish imported from West Bengal into the Southern CaribbeanNARA Subscribed
In response to a mortality event, seven Pangasius catfish ( Pangasianodon hypophthalmus ) were submitted to the University of the West Indies, School of Veterinary Medicine, Trinidad and Tobago, for diagnostic evaluation. These fish were part of a consignment that arrived from Kolkata two weeks earlier. Fish presented with perianal haemorrhage and blister‐like swellings on the skin which ruptured to leave ulcers. Edwardsiella...
Comparison of Edwardsiella ictaluri isolates from different hosts and geographic originsNARA Subscribed
The intraspecific variability of E. ictaluri isolates from different origins was investigated. Isolates were recovered from farm‐raised catfish ( Ictalurus punctatus ) in Mississippi, USA , tilapia ( Oreochromis niloticus ) cultured in the Western Hemisphere and zebrafish ( Danio rerio ) propagated in Florida, USA . These isolates were phenotypically homologous and antimicrobial profiles were largely similar. Genetically, isol...
