Shigella sonnei has caused unusually large outbreaks of shigellosis in California in 2014 and 2015. Preliminary data indicated the involvement of two distinct bacterial populations, one from San Diego and San Joaquin (SDi/SJo) and one from the San Francisco (SFr) Bay area. Whole-genome analysis and antibiotic susceptibility testing of 68 outbreak and archival isolates of S. sonnei were performe...

The recently reported concurrent outbreaks of Shigella sonnei infections in Denmark and Australia have been found to be linked to a common baby corn packing house in Thailand via trace-back of the distribution chain. Distribution records indicated that three additional countries received affected product from the implicated Thai packing house during the period of potential contamination. These ...

The global morbidity & mortality due to Shigella species is one of the major public health problems that accounts for thousands of deaths among the children’s below 5 years of age in many developing countries including Bangladesh. The present study was designed to isolate and characterize Shigella like organisms (Non-lactose fermenting colonies) by allowing biochemical characteristics, serology...

Three genes, ipgD, mxiC, and mxiA, all in the invasion region of the Shigella virulence plasmid, were sequenced from strains representing a range of Shigella serotypes and from two enteroinvasive Escherichia coli (EIEC) isolates. The plasmids can be classified into two relatively homogeneous sequence forms which are quite distinct. pINV A plasmids are found in Shigella flexneri strains F6 and F...

In July 2015, Shigella sonnei infections with a specific pulsed-field gel electrophoresis (PFGE) pattern linked to a multistate outbreak were recognized among men who have sex with men (MSM) in the Portland metropolitan area, and an outbreak investigation was initiated. During November 2015, isolates with PFGE patterns indistinguishable from the outbreak strain were identified in cases reported...
