“…Because of the low infectious dose and environmental persistence, S. sonnei can be spread by water (17)(18)(19)(20), food (21,22), and direct person-to-person transmission (23,24), which can trigger sporadic cases or family outbreaks and may cause more extensive secondary transmission from a common source (25,26). Therefore, S. sonnei outbreaks in childcare centers and schools can typically spread to the community or to other cities.…”

Here, we report for the first time a waterborne outbreak of Shigella sonnei in China in 2015. Eleven multidrug-resistant (MDR) S. sonnei isolates were recovered, showing high resistance to azithromycin and third-generation cephalosporins in particular, due to an mph(A)-and bla CTX-M-14 -harboring IncB/O/K/Z group transmissible plasmid of 104,285 kb in size. Our study highlights the potential prevalence of the MDR outbreak of S. sonnei in China and its further dissemination worldwide with the development of globalization.

“…From data prior to 2007, lettuce was associated with shigellosis outbreaks in Europe (Frost et al, 1995;Kapperud et al, 1995). In the USA, outbreaks were associated with fresh parsley (CDC, 1999) and tomatoes (Reller et al, 2006), and raw carrots (Gaynor et al, 2009) and salad preparation (Dunn et al, 1995).…”

European Food Safety Authority (EFSA), Parma, Italy ABSTRACTFood of non-animal origin (FoNAO) is consumed in a variety of forms, and a major component of almost all meals. These food types have the potential to be associated with large outbreaks as seen in 2011 associated with VTEC O104. A comparison of the incidence of human cases linked to consumption of FoNAO and of food of animal origin (FoAO) was carried out to provide an indication of the proportionality between these two groups of foods. It was concluded that outbreak data reported as part of EU Zoonoses Monitoring is currently the only option for EU-wide comparative estimates. Using this data from 2007 to 2011, FoNAO were associated with 10% of the outbreaks, 26% of the cases, 35% of the hospitalisations and 46% of the deaths. If the data from the 2011VTEC O104 outbreak is excluded, FoNAO was associated with 10% of the outbreaks, 18% of cases, but only 8% of the hospitalisations and 5% of the deaths. From 2008 to 2011 there was an increase in the numbers of reported outbreaks, cases, hospitalisations and deaths associated with food of non-animal origin. In order to identify and rank specific food/pathogen combinations most often linked to human cases originating from FoNAO in the EU, a model was developed using seven criteria: strength of associations between food and pathogen based on the foodborne outbreak data from EU Zoonoses Monitoring (2007-11), incidence of illness, burden of disease, dose-response relationship, consumption, prevalence of contamination and pathogen growth potential during shelf life. Shortcomings in the approach using outbreak data were discussed. The top ranking food/pathogen combination was Salmonella spp. and leafy greens eaten raw followed by (in equal rank) Salmonella spp. and bulb and stem vegetables, Salmonella spp. and tomatoes, Salmonella spp. and melons, and pathogenic Escherichia coli and fresh pods, legumes or grain.© European Food Safety Authority, 2013 KEY WORDSFood of non-animal origin, foodborne pathogens, foodborne outbreaks, food/pathogen combination, risk ranking SUMMARYThe European Commission asked EFSA"s BIOHAZ Panel to prepare a scientific Opinion on the public health risk posed by pathogens that may contaminate food of non-animal origin (FoNAO). In particular, this opinion addresses the first two terms of reference for the mandate, namely: (i) to compare the incidence of foodborne human cases linked to FoNAO and foodborne cases linked to food of animal origin (FoAO), and (ii) to identify and rank specific food/pathogen combinations most often linked to foodborne human cases originating from FoNAO in the EU.For the comparison of the incidence of foodborne human cases linked to FoNAO and foodborne cases linked to FoAO, the BIOHAZ Panel concluded that: the analysis of the outbreak data reported as part of EU Zoonoses Monitoring allows attribution of human cases to food of non-animal origin or food of animal origin, and is currently the only option for obtaining a EU-wide comparative estimate of the proportion ...

Objective: For the detection of outbreaks caused by Proteus mirabilis, strains clonal relations are determined methods as "pulsed-field gel electrophoresis (PFGE)". The aim of this study was optimization of a pulsed-field gel electrophoresis for molecular typing of P. mirabilis. Methods:In this study, PFGE' protocol is optimized for use in molecular typing of P. mirabilis. Phylogenetic analyzes of strains were evaluated with Bionumerics software system (version 6.01; Applied Maths, Sint-MartensLatem, Belgium). Results:This protocol compared with Gram-negative bacteria PFGE protocols, NotI enzyme is suitable for this bacterium. Electrophoresis conditions should be revealed as; -block 1: initial pulse duration 1 sec, ending pulse duration 30 sec, striking angle 120°, the current 6 V/cm 2 , temperature 14°C, time 8 hours; -block 2: initial pulse duration 30 sec, ending pulse duration 70 sec, striking angle 120°, the current 6 V/cm 2 , temperature 14°C, time 16 hours; -TBE, pH=8.4. Conclusion:P. mirabilis strains were typed by PFGE and Bionumerics analysis program were determined clonal relationships. The procedure was simple, reproducible and suitable for these bacteria. Also it was evaluated, because of reducing time, the solution volumes and enzymes can be economically. Outbreaks of nosocomial infections due to bacteria studied assessment and the potential to provide useful information about the degree of prevalence. This optimized protocol is allowed different centers' PFGE results to compare with other laboratories results. J Clin Exp Invest 2013; 4 (3): 306-312
