Global Distribution of Shigella sonnei Clones
2011
To investigate global epidemiology of Shigella sonnei, we performed multilocus variable number tandem repeat analysis of 1,672 isolates obtained since 1943 from 50 countries on 5 continents and the Pacific region. Three major clonal groups were identified; 2 were globally spread. Type 18 and its derivatives have circulated worldwide in recent decades.
TYPING OF LEGIONELLA PNEUMOPHILA SEROGROUP 1 BY SBT, MLVA AND SPOLIGOTYPING
2014
Introduction: The current typing method of Legionella pneumophila recommended by the European EWGLI Consortium is a multi locus sequence typing (MLST)-like protocol called sequence-based typing (SBT).This approach is highly portable and widely used to perform epidemiological surveys and outbreak investigation. Recent studies have demonstrated the values of using the multiple-locus variable-number tandem repeat (VNTR) analysis (MLVA) and the diversity of clustered regularly interspaced short palindromic repeat (CRISPR)-based typing technique (Spoligotyping) as genotyping markers. In this study we used these three methods for typing the L. pneumpophila isolates and for investigating the origi…
ESCRT Requirements for Murine Leukemia Virus Release
2016
The Murine Leukemia Virus (MLV) is a gammaretrovirus that hijack host components of the endosomal sorting complex required for transport (ESCRT) for budding. To determine the minimal requirements for ESCRT factors in MLV viral and viral-like particles (VLP) release, an siRNA knockdown screen of ESCRT(-associated) proteins was performed in MLV-producing human cells. We found that MLV VLPs and virions primarily engage the ESCRT-I factor Tsg101 and marginally the ESCRT-associated adaptors Nedd4-1 and Alix to enter the ESCRT pathway. Conversely, the inactivation of ESCRT-II had no impact on VLP and virion egress. By analyzing the effects of individual ESCRT-III knockdowns, VLP and virion releas…
