This case has the longest known incubation period for vaccine-derived poliomyelitis, and highlights our still rudimentary understanding of how poliovirus causes disease. The patient in this case, a 44 year old woman from Minnesota, had been diagnosed with common variable immunodeficiency (CVI) in 1991.  Patients with this disease lack B lymphocytes and therefore cannot produce antibodies that help control microbial infections. For example, individuals with CVI often develop chronic enterovirus infections. Furthermore, after receiving oral poliovirus vaccine, CVI pat... virology blog blogs http://www.medworm.com/rss/comments.php?id=4992114 Thu, 30 Jun 2011 17:44:49 +0100 4992114 http://www.medworm.com/index.php?rid=4531629&cid=t_324676_139_f&fid=38879&url=http%3A%2F%2Ftraffic.libsyn.com%2Ftwiv%2FTWiV122.mp3 Hosts: Vincent Racaniello, Dickson Despommier, Alan Dove, Rich Condit, and Welkin Johnson On episode #122 of the podcast This Week in Virology, the complete TWiV crew teams up with Welkin Johnson to explore the other AIDS epidemic, infection of monkeys with simian immunodeficiency virus, and its restriction by the cellular protein TRIM5.

He thinks DNA can teleport from one tube to another via electromagnetic signals. Is this the so-called “Nobel disease?” French virologist Luc Montagnier stunned his colleagues at a prestigious international conference when he presented a new method for detecting viral infections that bore close parallels to the basic tenets of homeopathy. Although fellow Nobel prize winners — who view homeopathy as quackery — were left openly shaking their heads, Montagnier’s comments were rapidly embraced by homeopaths eager for greater credibility. Montagnier told the conference last week that solutions containing the DNA o...

Gendelman (University of Nebraska Medical Centre, USA) writing in Lentiviruses and Macrophages: Molecular and Cellular InteractionsFor chronic lentiviral infections mononuclear phagocytes remain an enigma. On the one hand they are among the first cells contacted by virus and, despite a virtual armada of immunological tools, still serve as means to both spread and contain infection. Virus particles can simultaneously assemble and hide in intracellular compartments, largely free from immune attack. Interestingly, the mononuclear phagocytes are not destroyed by the virus and throughout infection they still contribute to host immunity while at the same time perpetuating lentiviral dissemination. Infected mononuclear phagocytes are readily observed in lymph nodes and organs such as...

BIV has a broad cell tropism and causes a mild lymphoproliferative disorder with low viral titres and no reproducible disease sequelae. JDV has a more restricted cell tropism than BIV and infects Bali cattle in Indonesia, replicating to high viral titres during an acute disease period characterized by lymph node enlargement, leucopaenia and high rectal temperatures. The similarities and differences between these two genetically and antigenically closely related viruses and between other lentiviruses will be reviewed in this chapter with particular regard to their cell tropism, pathogenesis and genetic composition.from Lentiviruse...

Crossing of species barriers resulted in adaptation to the human host and subsequent acquisition of a pathogenic phenotype. Naturally occurring T lymphocyte-tropic lentiviral infections are highly prevalent and productive but are not usually pathogenic for native hosts. Crossing species barriers may produce an abortive infection or, as in the case of the HIVs, may enhance virulence after several cycles of transmission. The large number of species carrying these viruses may suggest that infection...
