Induced Biliary Excretion Of Listeria Monocytogenes, Jonathan Hardy, Jeffrey J. Margolis, Christopher H. Contag

Jeffrey Margolis

Listeria monocytogenes is a ubiquitous gram-positive bacterium that can cause systemic and often lifethreatening
disease in immunocompromised hosts. This organism is largely an intracellular pathogen; however,
we have determined that it can also grow extracellularly in animals, in the lumen of the gallbladder. The
significance of growth in the gallbladder with respect to the pathogenesis and spread of listeriosis depends on
the ability of the bacterium to leave this organ and be disseminated to other tissues and into the environment.
Should this process be highly inefficient, growth in the gallbladder would have no impact on pathogenesis or
spread, but if …

Absence Of Spiroplasma Or Other Bacterial 16s Rrna Genes In Brain Tissue Of Hamsters With Scrapie, Irina Alexeeva, Ellen J. Elliott, Sandra Rollins, Gail E. Gasparich, Jozef Lazar, Robert G. Rohwer Dec 2005

Absence Of Spiroplasma Or Other Bacterial 16s Rrna Genes In Brain Tissue Of Hamsters With Scrapie, Irina Alexeeva, Ellen J. Elliott, Sandra Rollins, Gail E. Gasparich, Jozef Lazar, Robert G. Rohwer

Gail Gasparich

Spiroplasma spp. have been proposed to be the etiological agents of the transmissible spongiform encephalopathies (TSEs). In a blind study, a panel of 20 DNA samples was prepared from the brains of uninfected hamsters or hamsters infected with the 263K strain of scrapie. The brains of the infected hamsters contained ≥1010 infectious doses/g. The coded panel was searched for bacterial 16S rRNA gene sequences, using primers selective for spiroplasma sequences, primers selective for mollicutes in general, and universal bacterial primers. After 35 PCR cycles, no samples were positive for spiroplasma or any other bacterial DNA, while control Spiroplasma mirum genomic …
