Sodium periodate mediated oxidative transformations in organic synthesis. Nat Rev Microbiol. Norovirus is a highly contagious viral illness that often goes by other names, such as viral gastroenteritis, stomach flu, and food poisoning. 2016. Most bacteria can be broadly classified as Gram positive or Gram negative. An example of dual typing nomenclature is the GII.4 Sydney[P16] norovirus strain that has caused the majority of all norovirus outbreaks in the United States in recent years (seeCaliciNet data). Regina Bailey is a board-certified registered nurse, science writer and educator. Two genera of Gram positive cocci noted for their role as human pathogens are Staphylococcus and Streptococcus. Han L, Tan M, Xia M, Kitova EN, Jiang X, Klassen JS. The antibodies were made against human HBGA antigens, leaving a potential for cross reactivity and sometimes ambiguous results. Noroviruses are nonenveloped, positive-sense, single-stranded RNA viruses belonging to the Caliciviridae viral family. To modify the sugar residues, three strategies were attempted: treatment with sodium periodate (100mM) to oxidize carbohydrates [15]; treatment with sulfo-NHS-acetate (100uM) to block amine groups [16]; and digestion with Vibrio cholera neuraminidases to cleave sialic acid [17] (Additional file 1). Thus, the two types of bacteria are distinguished by gram staining. Gram negative coccobacillus bacteria have bacterial shapes that are in between spherical and rod shaped. Correspondence to J Am Chem Soc. LPS is a large glycolipid complex that protects bacteria from harmful substances in their environment. Recent advances in understanding noroviruses. EAA, MDM, and LAJ analyzed results and wrote portions of the manuscript.
