Coastal communities are uniquely vulnerable to sea-level rise (SLR) and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in coming years. The U.S. Geological Survey has developed the Sediment-Bound Contaminant Resiliency and Response (SCoRR) strategy to define baseline and post-event sediment-bound environmental health (EH) stressors. These data document toxicity measured by reduction of the light emission of Aliivibrio (formerly Photobacterium) fischeri and the inhibition of polymerase chain reactions caused by environmental...
It is unclear whether DNA lysis buffers used for preservation of whole blood samples from Hawaiian forest birds cause denaturation and loss of antigen binding capability of antibody molecules. If their antigen binding capability is not affected, then the samples can be used in serological assays to provide an independent assessment of the accuracy of PCR (polymerase chain reaction) diagnostic tests for avian malaria. This data set reports raw absorbance measurements that were collected with a BioRad Model 3550 ELISA plate reader at a wavelength setting of 405 nm for different dilutions of blood from an infected Hawaii Amakihi that were preserved in PBS (phosphate buffered saline), TEN (Tris-Ethylenediaminetetraacetic...

This data set was collected to provide examples and aid in developing a standardized way of determining LOD and LOQ for eDNA assays and has 3 data files. GEDWG_LOD_DATA3.csv is raw qPCR data from multiple labs running multiple standards of known concentration for eDNA assays they regularly use. Comparison-Data.csv is the merged data output from running a generic LOD/LOQ calculator script multiple times with different LOD model settings. The generic LOD/LOQ calculator script is available at: https://github.com/cmerkes/qPCR_LOD_Calc, and details about the multiple settings used are commented in the analysis script available at: https://github.com/cmerkes/LOD_Analysis

If their antigen binding capability is not affected, then the samples can be used in serological assays to provide an independent assessment of the accuracy of PCR (polymerase chain reaction) diagnostic tests for avian malaria. This data set provides derived Percent ELISA (Enzyme linked Immunosorbant Assay) Values calculated from adjusted absorbance measurements that were collected with a BioRad Model 3550 ELISA plate reader at a wavelength setting of 405 nm.

We developed and validated conventional and quantitative real-time PCR assays for the detection of DNA from the myxozoan parasite Tetracapsuloides bryosalmonae, the causative agent of proliferative kidney disease in fish. Assays were tested on fish tissue and on field-collected water samples to assess diagnostic and environmental DNA capabilities. The specificity, sensitivity, and broad applicability of the present assays surpass previous methods for detecting T. bryosalmonae DNA from fish tissue and water samples.

This data set provides raw absorbance measurements that were collected with a BioRad Model 3550 ELISA plate reader at a wavelength setting of 405 nm for different dilutions of blood from an uninfected Hawaii Amakihi. The blood was preserved in different lysis buffers or placed in phosphate buffered...

Freshwater mussels of the order Unionida are among the most endangered animal groups globally, but the causes of population declines are often enigmatic with little known about the role of disease. In 2018, we collected wild adult pheasantshell (Actinonaias pectorosa) and mucket (Actinonaias ligamentina) during an epidemiologic survey investigating an ongoing mussel mass mortality event in the Clinch River, USA. Histopathology and transmission electron microscopy showed a novel microsporidian parasite primarily infecting the ovary of pheasantshell. Sequencing of the small subunit rRNA gene produced a 1333 bp sequence with greatest similarity to Pseudonosema cristatellae (AF484694.1; 86.36%; e-value = 0), a microsporidium...

There is an increasing emphasis on effects-based monitoring to document responses associated with exposure to complex mixtures of chemicals, climate change, pathogens, parasites and other environmental stressors in fish populations. For decades aquatic monitoring programs have included the collection of tissues preserved for microscopic pathology. Consequently, formalin-fixed, paraffin-embedded (FFPE) tissue can be an important reservoir of nucleic acids as technologies emerge that utilize molecular endpoints. Despite the cross-linking effects of formalin, its impact on nucleic acid quality and concentration, amplification, and sequencing are not well described. While fresh-frozen tissue is optimal for working with...

It is unclear whether DNA (Deoxyribonucleic Acid) lysis buffers used for preservation of whole blood samples from Hawaiian forest birds cause denaturation and loss of antigen binding capability of antibody molecules. If their antigen binding capability is not affected, then the samples can be used in serological assays to provide an independent assessment of the accuracy of PCR (polymerase chain reaction) diagnostic tests for avian malaria. This data release consists of three tabular datasets of raw absorbance measurements that were collected with a BioRad Model 3550 ELISA (Enzyme linked Immunosorbant Assay) plate reader at a wavelength setting of 405 nm from serial dilutions of whole blood that were preserved with...
