Laboratory challenge of Pacific herring Clupea pallasii to Vibrio anguillarum and V. ordallii

Controlled waterborne exposures of Pacific herring (Clupea pallasii) to Vibrio anguillarum and V. ordalii failed to result in overt signs of disease or mortality from vibriosis. Cumulative mortalities among Vibrio - exposed Pacific herring (3.3 - 5.0 percent) were similar to those of saline-exposed negative controls (10 percent) and significantly less (P less than 0.

Survival, viral load and neutralizing antibodies in steelhead trout and cell cultures exposed to infectious hematopoietic necrosis virus (IHNV) at 3 temperatures

Environmental variation has important effects on host-pathogen interactions, affecting large-scale ecological processes such as the severity and frequency of epidemics. However, less is known about how the environment modulates viral fitness traits and within host infection processes.

Data from 2018 Experiment on Effects of Temperature on Survival and Growth of Juvenile Lost River Suckers (Deltistes luxatus) naturally exposed to Ichthyobodo spp

Data included in this data set are for an experiment conducted in 2018. Data were collected on survival, growth, food consumption, and Ichthyobodo copy numbers of Lost River suckers exposed to five different temperature groups. There are five levels of data.

Cyanobacterial toxin effects on inflammatory response of human toll-like receptors (TLRs)

Various stressors including temperature, environmental chemicals and toxins can have profound impacts on immunity to pathogens. It is believed that increased eutrophication near rivers and lakes coupled with climate change are predicted to lead to increased algal blooms. Currently, the effects of cyanobacterial toxins on disease resistance in mammals is a largely unexplored area of research....

Data on blood cells of the collector urchin, Tripneustes gratilla

Echinoderms such as urchins are important in marine ecosystems, particularly as grazers, and unhealthy urchins can have important ecological implications. For instance, unexplained mortalities of Diadema sp. in the Caribbean were followed by algal overgrowth and subsequent collapse of coral reef ecosystems. Unfortunately few tools exist to evaluate echinoderm health making management of mo...

Skin mycobiomes of eastern North American bats

North American bats have experienced catastrophic population declines from white-nose syndrome (WNS), a fungal disease caused by Pseudogymnoascus destructans (Pd). Although Pd can infect many hibernating bat species, population-level impacts of WNS vary by host species. Microbial skin assemblages, including the fungal component (mycobiome), can influence host resistance to inf

Effects of early life stage exposure of largemouth bass to atrazine or a model estrogen (17α-ethinylestradiol)

Largemouth base histological development and transcriptomic changes in gonad tissue after early life stage exposure to Atrazine (1-Chloro-3-ethylamino-5-isopropylamino-2,4,6-triazine) or the model estrogen 17α-ethinylestradiol.

Immunological histopathology of American kestrels (Falco sparverius) exposed in ovo to two persistent organic pollutants -- SCCPs and TBBPA-BDBPE

This work is part of a study of the immunological effects of exposure to alternative flame retardants in avian species. For the pathology portion of the study, spleens and bursas from American kestrels (Falco sparverius) exposed by egg injection to varying doses of short-chain chlorinated paraffins (SCCPs) and the flame retardant TBBPA-BDBPE were examined microscopically for architectur

Immunological histopathology of American kestrels (Falco sparverius) exposed to the flame retardant isopropyl triphenyl phosphate

This work is part of a study of the immunological effects of exposure to alternative flame retardants in avian species. For the pathology portion of the study, hatchling American kestrels (Falco sparverius) were exposed to the flame retardant isopropyl triphenyl phosphate (ITP) and then challenged with a synthetic analogue of viral double-stranded RNA, polyinosinic:polycytidylic aci

Necropsy reference number and summary collection information for Washington state population of northern sea otters examined during 1989-2010

Morbillivirus epidemics in marine mammals first gained prominence in 1988 when an outbreak of phocine distemper virus (PDV) occurred in European harbor seals (Phoca vitulina vitulina). Prior to 2001, all serosurveys for morbilliviruses in sea otters (Enhydra lutris) in California, Washington and Alaska documented a 0% seroprevalence. The first published serodetections of morbi
