Mouse Norovirus infection reduces the surface expression of MHC class I proteins and inhibits CD8+ T cell recognition and activation.

J Virol 2018 Jul 5. Epub 2018 Jul 5.

Department of Microbiology and Immunology, University of Melbourne at the Peter Doherty Institute for Infection and Immunity, Victoria, Melbourne 3010

Human Noroviruses are highly infectious, single stranded RNA (ssRNA) viruses and the major cause of non-bacterial gastroenteritis worldwide. With the discovery of Murine Norovirus (MNV) and the introduction of an effective model for norovirus infection and replication, knowledge about infection mechanisms and its impact on the host immune response has progressed. A major player in the immune response against viral infections is the group of major histocompatibility complex (MHC) class I proteins, which present viral antigen to immune cells. Read More

Provincial Public Health Laboratory, Eastern Health Microbiology Services, St. John's, NL.

As clinical laboratories transition to using culture-independent detection test (CIDT) panels for cases of acute gastroenteritis, culture of clinical specimens is becoming less common. The reduction in bacterial cultures available for public health activities is expected to hinder surveillance and outbreak response by public health laboratories at the local, provincial, national and international levels.

Fecal microbiota transplantation for the treatment of patients with ulcerative colitis and other gastrointestinal conditions beyond Clostridium difficile infection: an update.

Drugs Today (Barc) 2018 Feb;54(2):123-136

Department of Internal Medicine and Gastroenterology, Policlinico Agostino Gemelli, Università Cattolica del Sacre Cuore, Rome, Italy.

Fecal microbiota transplantation (FMT) is the transplantation of microbial gut contents from a healthy individual into the gastrointestinal tract of a person with a disease, with a view to increasing the recipient's gut microbial diversity and bacterial richness and restoring microbial homeostasis. FMT has been proven to be a safe and effective treatment for Clostridium difficile infection (CDI) and it is now a recommended treatment for recurrent or refractory infection. FMT is not currently recommended for use outside of CDI due to concerns regarding outcome and safety; however, several case series and randomized controlled trials have described its use in a research environment for a few gastrointestinal conditions related to intestinal dysbiosis including ulcerative colitis (UC), Crohn's disease (CD) and irritable bowel syndrome (IBS).
