We describe the unexpected binding of S-layer to cells devoid of DC-SIGN but also confirm that the presence of DC-SIGN was essential for S-layer’s antiviral activity. S-layer protein exerted its antiviral effect with different kinetics than mannan, a known viral inhibitor that also acts on DC-SIGN (Yu et al., 2017). Together our results suggest that inhibition of viral entry by S-layer occurs via a novel S-layer/DC-SIGN interaction. Materials and Methods Isolation of S-Layer Proteins S-layer proteins were extracted from overnight cultures of L. acidophilus ATCC 4356 cells grown in MRS medium at 37°C by using 6...

In this study, the multivariate linear mixed model (LMM) was used to calculate the P-value to determine interesting SNPs at each time point using GEMMA software v0.97 (Zhou and Stephens, 2014). Growth data from both untreated and vancomycin-treated group formed the bivariate phenotype, which differs hugely from the univariate phenotype. Therefore, LMM developed for univariate phenotype cannot be applied to analyze correlated phenotype directly; methods allowing LMM algorithm specific to multivariate and correlated phenotype [multivariate LMMs (mvLMMs)] are in urgent need. GEMMA software could extend a standard LMM to mvLMM...

Vega Masignani1, Mariagrazia Pizza1 and E. Richard Moxon2* 1GSK Vaccines, Siena, Italy 2Department of Pediatrics, Oxford University, Oxford, United Kingdom The discovery of vaccine antigens through whole genome sequencing (WGS) contrasts with the classical hypothesis-driven laboratory-based analysis of microbes to identify components to elicit protective immunity. This radical change in scientific direction and action in vaccine research is captured in the term reverse vaccinology. The complete genome sequence of an isolate of Neisseria meningitidis serogroup B (MenB) was systematically analyzed to identify prot...

AbstractNorovirus (NoV) is the leading cause of acute viral gastroenteritis outbreaks in the world. These outbreaks are frequently associated with bivalve shellfish consumption, particularly because these products are often eaten raw or only slightly cooked. In Morocco, regulations concerning the acceptable levels of enteric bacteria indicator organisms in these products have been put in place. However, these regulations do not take into account the risk of viral contamination, and many gastroenteritis outbreaks have been linked to the ingestion of bivalve shellfish from areas that comply with the current food safety crite...
