Spiroplasma Penaei Sp. Nov., Associated With Mortalities In Penaeus Vannamei, Pacific White Shrimp, Linda M. Nunan, Donald V. Lightner, Marietta A. Oduori, Gail E. Gasparich Oct 2005

Spiroplasma Penaei Sp. Nov., Associated With Mortalities In Penaeus Vannamei, Pacific White Shrimp, Linda M. Nunan, Donald V. Lightner, Marietta A. Oduori, Gail E. Gasparich

A new bacterial strain, designated SHRIMPT, isolated from the haemolymph of the Pacific white shrimp, Penaeus vannamei, was serologically distinct from other spiroplasmas. Cells of this strain were helical in form and variable in length. Examination by electron microscopy revealed wall-less cells delineated by a single cytoplasmic membrane. The organisms grew well in M1D media supplemented with 2 % NaCl. Strain SHRIMPT grew at temperatures of 20–37 °C, with optimum growth occurring at 28 °C. The strain catabolized glucose and hydrolysed arginine, but did not hydrolyse urea. The G+C content of the DNA was 29±1 mol%. Strain SHRIMPT (=ATCC BAA-1082T=CAIM …

The Importance Of Experimental Design In Proteomic Mass Spectrometry Experiments: Some Cautionary Tales, Jeffrey S. Morris, Jianhua Hu, Kevin R. Coombes, Keith A. Baggerly

Jeffrey S. Morris

Proteomic expression patterns derived from mass spectrometry have been put forward as potential biomarkers for the early diagnosis of cancer and other diseases. This approach has generated much excitement and has led to a large number of new experiments and vast amounts of new data. The data, derived at great expense, can have very little value if careful attention is not paid to the experimental design and analysis. Using examples from surfaceenhanced laser desorption/ionisation time-of-flight (SELDI-TOF) and matrix-assisted laser desorption–ionisation/time-of-flight (MALDI-TOF) experiments, we describe several experimental design issues that can corrupt a dataset. Fortunately, the problems we identify can be …


What Communities Should Do Pre-Event To Support Public Health Post-Event Assessments, Surveillance And Monitoring, Thomas Lyons Carr Iii Feb 2005

What Communities Should Do Pre-Event To Support Public Health Post-Event Assessments, Surveillance And Monitoring, Thomas Lyons Carr Iii

Thomas Lyons (Thom) Carr III Appl.Sc., CEM

[Abstract written March 2008, TLC] Under worst-case planning assumptions used by some major metropolitan areas, a Neighbor-to-Neighbor self-help program model is the primary link between citizens and the professional response personnel of the responsible government agencies.

In the Neighbor-to-Neighbor self-help program model or a Community Emergency Management Plan (CEMP) calls on the citizens in neighborhoods to identify and establish cluster emergency preparedness committees, Cluster Emergency Coordination Centers (CECC) and Community Emergency Response Teams (CERT). Missing from these plans or what is not articulated is how constant Public Health Post-Event Surveillance, Monitoring and Assessments will be done. Given the worst-case planning …

Spiroplasma Atrichopogonis Sp. Nov., From A Ceratopogonid Biting Midge, R. Thomas Koerber, Gail E. Gasparich, Mark F. Frana, William L. Grogan Dec 2004

Spiroplasma Atrichopogonis Sp. Nov., From A Ceratopogonid Biting Midge, R. Thomas Koerber, Gail E. Gasparich, Mark F. Frana, William L. Grogan

Gail Gasparich

Spiroplasma sp. strain GNAT3597T was isolated from the biting midge genus Atrichopogon (Diptera: Ceratopogonidae). It was serologically distinct from other Spiroplasma species, groups or subgroups. Dark-field microscopy of the cells revealed the classical helical shape and subsequent transmission electron microscopy revealed cells surrounded by only a cell membrane (i.e. lacking a cell wall). Growth of strain GNAT3597T occurred in M1D medium at 30 °C. Strain GNAT3597T catabolized both glucose and arginine, but did not hydrolyse urea. The DNA G+C content of strain GNAT3597T was 29±1 mol%. Only one strain, SMCAT (Spiroplasma mirum), is serologically related to strain GNAT3597T, although the …
