Gigas Bacterial Challenge – 1hr & 3hr Challenges with Vibrio vulnificus

kubu4 — Wed, 12 Jan 2011 05:10:46 +0000

0000-0002-2747-368X

400mL O/N culture (1x LB+1% NaCl, 37C, 150RPM, 1L flask) of V.vulnificus (STRAIN??) and V.tubiashii (Strain: RE22) were pelleted (4300RPM, 25C, Sorvall ST-H750 rotor). Supe was removed and pellets were each resuspended in 50mL sea water. 1mL was taken from each to use for dilutions to determine colony forming units (CFU).

Two containers were set up with each containing 16 C.gigas, and air stone and 8L of sea water. The entire 50mL of V.vulnificus was added to one of the containers. 8 oysters were sampled (gill and mantle tissue) from each container at 1hr and 3hrs after the addition of V.vulnificus culture and immediately frozen on dry ice. Samples were stored @ -80C in the “Gigas Vibrio Exposure 1,3hrs 1/11/11″ box. Additionally, 1mL samples of the water were taken at each time to determine CFU in the water.

In addition to the samples taken above, the following tissues were taken from 5 control oysters at the 3hr time point and treated/stored in the same fashion as the others, specifically for assessment of cyclooxygenase tissue distribution analysis: muscle, digestive gland/gonad (difficult to differentiate)

All oysters were measured. Morphometric data is here.

Bacteria – C.pugetti culture (from 20090713)

kubu4 — Thu, 23 Jul 2009 16:15:54 +0000

0000-0002-2747-368X

1L liquid culture (grown for 10 days) was split into two UV-sterilized bottles. Cells were pelleted in a Sorvall T21 centrifuge using the bucket rotor for 30mins @ 4200RPM, 4C. Supe was removed and bacterial pellets were stored @ -20C.

Bacteria – C.pugetti large culture

kubu4 — Mon, 13 Jul 2009 16:41:04 +0000

0000-0002-2747-368X

One of the three starter liquid cultures from 20090706 wee used to inoculate 1L of Marine Broth + biphenyl. Incubated 200RPM @ 28C.

0000-0002-2747-368X

Inoculated 3 x 5mL Marine Broth + biphenyl crystals (UV sterilized) cultures from frozen stock in 50mL Falcon tubes. Incubated 200RPM, 28C. Will use these are starter cultures to inoculate larger cultures.
