Phenotyping and genotyping have been carried out on 64 epidemic and sporadic isolates of Shigella sonnei identified in Italy in the years 2001 to 2003. Class 2 integron carriage has been also investigated. Isolates from four of the five outbreaks and four of six sporadic cases were biotype g, pulsed-field gel electrophoresis type B, and class 2 integron positive, suggesting emergence and spread of an epidemic clone in Italy.

Unlabelled: Toxin:antitoxin (TA) systems are widespread in bacteria and were first identified as plasmid addiction systems that kill bacteria lacking a TA-encoding plasmid following cell division. TA systems have also been implicated in bacterial persistence and antibiotic tolerance, which can be precursors of antibiotic resistance. Here, we identified a clinical isolate of (CS14) with a remarkably stable pINV virulence plasmid; pINV is usually frequently lost from , but plasmid loss was not detected from CS14.

infection poses a significant public health challenge in the developing world. However, lack of a widely available mouse model that replicates human shigellosis creates a major bottleneck to better understanding of disease pathogenesis and development of newer drugs and vaccines. BALB/c mice pre-treated with streptomycin and iron (FeCl) plus desferrioxamine intraperitoneally followed by oral infection with virulent resulted in diarrhea, loss of body weight, bacterial colonization and progressive colitis characterized by disruption of epithelial lining, loss of crypt architecture with goblet cell depletion, increased polymorphonuclear infiltration into the mucosa, submucosal swelling (edema), and raised proinflammatory cytokines and chemokines in the large intestine.

We describe 3 cases of extensively drug-resistant Shigella sonnei infections among men who have sex with men in Los Angeles, CA. Using whole-genome sequencing, we determined that they are highly genetically related, exhibit similar antimicrobial resistomes, and appear to be distinct from other circulating strains. These cases highlight the rapid expansion of extensively drug-resistant Shigella in the United States and the urgent need for appropriate detection and management.
