constant and variable sequences which may occur either at the level of DNA or RNA. It is now generally accepted, that both B and T lymphocytes directly participate in antigen recognition, but the existence and nature of T cell receptors is still debated. Some could not find them; others could, but found them passively absorbed. When they were detected, they looked IgM-like (IgT) or like IgA wit...
متن کاملCystic fibrosis microbiology: Advances in antimicrobial therapy.
Much of the improvement in the survival of individuals with cystic fibrosis (CF) is due to advancements in antimicrobial treatments. New aerosolized antibiotic formulations have recently been introduced (such as inhaled aztreonam), and others are in development (inhaled levofloxacin and liposomal amikacin). Licensed dry powder formulations include tobramycin inhalation powder and dry powder col...
متن کاملRecent advances in sea-ice microbiology.
Over the past 50 years there has been much effort invested in the investigation of the ecology of sea ice. Sea ice is an ephemeral feature of the Arctic and Southern Oceans and smaller water bodies such as the Baltic and Caspian Seas. The semisolid ice matrix provides a range of habitats in which a diverse range of microbial organisms thrive. In the past 5 years there has been considerable step...
متن کاملPolar Microbiology: Recent Advances and Future Perspectives
Most of the Earth's biosphere is cold (85% is permanently exposed to temperatures below 5 °C), with 14% being polar. Polar regions are areas of the globe surrounding the poles. They are different in that the Arctic is a frozen ocean surrounded by continental landmasses and open oceans, whereas Antarctica is a frozen continent surrounded solely by oceans. The Arctic has numerous definitions; the...
متن کاملRecent advances in quantitative PCR (qPCR) applications in food microbiology.
Molecular methods are being increasingly applied to detect, quantify and study microbial populations in food or during food processes. Among these methods, PCR-based techniques have been the subject of considerable focus and ISO guidelines have been established for the detection of food-borne pathogens. More particularly, real-time quantitative PCR (qPCR) is considered as a method of choice for...
