"Sampling and Analytical Methodology:
In the first trial, a Labyrinthulomycota culture held at 22 degrees C was
divided into 18 sub-cultures that were incubated at 15 degrees C, 20 degrees
C, 25 degrees C, 30 degrees C, and 32 degrees C in triplicate for three days.
Culture temperatures and incubation period were based on previous visual
observations of Labyrinthulomycota growth, where over-growth of culture flasks
occurs after three days at temperatures of 25 degrees C and higher. In the
second trial, nine sub-cultures were incubated at 20 degrees C, 25 degrees C,
and 30 degrees C in triplicate for three days.
In the second trial, total protein was also assessed. After three days, the
media was poured off, rinsed once with 3 mLs of 0.22 um-filtered artificial
sea water, and replaced with 3 mLs of 0.22 um-filtered artificial sea water.
With a sterile wooden dowel, the bottom of each culture was scraped until no
Labyrinthulomycota growth was visible on the bottom of the culture. 700 uL of
each culture was placed in a bead beater and mixed at 300 rpm for 30 sec; 400
uL was set aside for protein assays and 300 uL for cell counts and held on ice
until use.
Prior to counting using a hemocytometer, cells were vortexed for about 20 sec.
In each culture, cells were counted in triplicate.
Total protein was extracted from each sample by adding 400 uL of extraction
buffer (0.15 ug mL-1 DTT in Tris-HCl) to each tube. The contents of the tube
were mixed and lysed for 2 minutes with the Fisherbrand disposable pestle
grinder system, and incubated for 45 minutes on ice for extractions. Protein
was measured using the DC protein kit (Bio-Rad), and read in triplicate using
the Synergy HT multi-Detection microplate reader with KC4 software (Biotek
Instruments, Vermont) at 750 nm.";

"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).
Coral reef ecosystems are highly endangered by recent increases in temperature and by projected increases in ocean acidification. Although temperature has been identified as a driver of some coral disease outbreaks, nothing is known about direct effects of acidification on host immunity and pathogen virulence, or the potential for synergism with temperature. Natural coral populations often suffer from simultaneous infection by multiple pathogens that can also influence host immune responses, but co-infection dynamics have not been investigated in invertebrate systems lacking classical adaptive immunity. Changing climate will very likely influence the outcome of single and co-infection.
This project will investigate the influence of environmental stress on co-infection dynamics of the sea fan coral, Gorgonia ventalina, with a fungal pathogen, Aspergillus sydowii and a protist parasite, SPX. The goal is to identify the mechanisms through which multiple infections, temperature and acidification modify host resistance, leading to changes in within- and among-colony rates of disease spread.
The objectives of this project are to:
(1) Identify incidence and co-infection frequency of Aspergillus sydowii and SPX. Detailed field surveys of the two diseases will test the hypothesis that co-infection is significant, provide valuable information about drivers of aspergillosis, and will help to characterize an emerging new sea fan disease.
(2) Investigate how co-infection influences sea fan susceptibility, resistance, and within host disease dynamics. Through manipulative lab inoculation experiments we will test the hypothesis that single infections increase susceptibility to a second pathogen.
(3) Examine the effects of temperature increase and ocean acidification on pathogen virulence, on underlying host resistance, and on the dynamics of single and co-infections.
The hypotheses that acidification will increase pathogen virulence and host susceptibility will be tested in a temperature and pH controlled experimental system. This system will also allow the potential synergistic effects of temperature and acidification on host immunity and co-infection dynamics to be explored. The primary intellectual merit of the proposed work will be a greater understanding of how changing climate mediates co-infection and immunity in a non-model invertebrate. While fungal pathogens are primarily opportunistic, labyrinthulid protozoans are recognized as primary pathogens in shellfish. Even in shellfish, little is known about co-infections involving labyrinthulids, and these protists are entirely unstudied in corals.

Data Access Protocol (DAP) and its
selection constraints.
The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.
Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names,
followed by a collection of
constraints (e.g., variable<value),
each preceded by '&' (which is interpreted as "AND").
