    In high-income countries, oropharyngeal tularemia is associated with hunting or eating infected game or drinking contaminated water.1,2 We describe a cluster of cases of oropharyngeal tularemia that appears to have been caused by the consumption of freshly pressed grape must by grape harvesters volunteering at a vineyard in Rhineland-Palatinate, Germany, in October 2016.  Reference:  N Engl J Med 2018; 379:197-199. https://www.nejm.org/doi/full/10.1056/NEJMc1800353 ----------------------------------------------------------- Sigue este Blog en Facebook y Twitter Ayúdanos a traducir las fichas de seguridad de microorganismos. www.seguridadbiologica.blogspot.com […]

    Prion diseases are progressive, incurable and fatal neurodegenerative conditions. The term ‘prion’ was first nominated to express the revolutionary concept that a protein could be infectious. We now know that prions consist of PrPSc, the pathological aggregated form of the cellular prion protein PrPC. Over the years, the term has been semantically broadened to describe aggregates irrespective of their infectivity, and the prion concept is now being applied, perhaps overenthusiastically, to all neurodegenerative diseases that involve protein aggregation. Indeed, recent studies suggest that prion diseases (PrDs) and protein misfolding disorders (PMDs) share some common disease mechanisms, which could have implications for potential treatments. Nevertheless, the transmissibility of bona fide prions is unique, and PrDs should be considered as distinct from other PMDs.

    FRAGMENTO:Iatrogenic Creutzfeldt-Jakob Disease (CJD) is simply CJD (most likely sporadic CJD) that is transmitted from one person to another by medical or surgical treatment (table 2) [20]. It is important to note that all forms of prion disease are potentially transmissible, even, remarkably, autosomal dominantly inherited genetic diseases. In addition, there are increasing concerns that variant CJD will lead to significant secondary transmission, with 2 reported cases of probable blood transmission [21, 22].REFERENCE:Richard Knight; Creutzfeldt-Jakob Disease: A Rare Cause of Dementia in Elderly Persons, Clinical Infectious Diseases, Volume 43, Issue 3, 1 August 2006, Pages 340–346, ----------------------------------------------------------- Sigue este Blog en Facebook y Twitter Ayúdanos a traducir las fichas de seguridad de microorganismos. www.seguridadbiologica.blogspot.com […]

  • #Prions: Beyond a Single...
    by noreply@blogger.com (Julietta Torres) on July 5, 2018 at 2:00 pm

    Since the term protein was first coined in 1838 and protein was discovered to be the essential component of fibrin and albumin, all cellular proteins were presumed to play beneficial roles in plants and mammals. However, in 1967, Griffith proposed that proteins could be infectious pathogens and postulated their involvement in scrapie, a universally fatal transmissible spongiform encephalopathy in goats and sheep. Nevertheless, this novel hypothesis had not been evidenced until 1982, when Prusiner and coworkers purified infectious particles from scrapie-infected hamster brains and demonstrated that they consisted of a specific protein that he called a “prion.” Unprecedentedly, the infectious prion pathogen is actually derived from its endogenous cellular form in the central nervous system. Unlike other infectious agents, such as bacteria, viruses, and fungi, prions do not contain genetic materials such as DNA or RNA. The unique traits and genetic information of prions are believed to be encoded within the conformational structure and posttranslational modifications of the proteins. Remarkably, prion-like behavior has been recently observed in other cellular proteins—not only in pathogenic roles but also serving physiological functions. The significance of these fascinating developments in prion biology is far beyond the scope of a single cellular protein and its related disease. REFERENCIA:Das AS, Zou W-Q.
