“…Such organisms have been found in healthcare facilities since the 1980s, but are now of even greater concern due to the increase in incidence in the community, especially the CTX-M subtypes [32]. Dissemination of related ESBL-producing strains have also been documented in Canada [14], Spain [33], Portugal [34], Croatia [35] and the UK [36, 37]. ESBL-producing E. coli O25:H4-ST131 is one clone which appears to have spread widely and has been responsible for several outbreaks.…”

A systematic review of outbreak and non-outbreak studies of infections caused by extraintestinal pathogenic Escherichia coli (ExPEC) was conducted. This review examines the epidemiology, seasonality, source or mode of transmission, and temporal changes, based on E. coli serogroup, in ExPEC causing sporadic vs. outbreak-associated infections. Twelve outbreak and 28 non-outbreak studies were identified. The existence of ExPEC outbreaks was well supported. Three of four outbreak reports indicated peak periods during the winter months. Serogroups associated with outbreak infections ranged from 1% to 26% (average 11·4%) vs. (range 1-15%, average 3·5%) for serogroups associated with sporadic infections; the distribution of serogroups also differed for outbreak and non-outbreak infections. Study authors indicated that the outbreaks may have resulted from foodborne transmission, but direct evidence was unavailable. This review provides evidence that the epidemiology of endemic vs. epidemic ExPEC infections differs; however, study reporting quality limited epidemiological inferences.

“…Unfortunately, despite the comparatively large numbers of infants studied, there is still too great a diversity to reach fully definitive conclusions. Strains belonging to these O‐groups continue to be isolated from severe human EII and now include extended‐spectrum β‐lactamase‐producing E. coli (Vranes et al. 2008).…”

Aim: To examine the diversity of Escherichia coli serotypes found in the intestinal contents of infants who died of Sudden Infant Death Syndrome (SIDS) compared with that in comparison infants. Methods and Results: Over the 3‐year period, 1989–1991, in South Australia and Victoria (Australia), a total of 687 E. coli isolates from 231 patients with SIDS (348 isolates), 98 infants who had died from other causes (144 isolates) and 160 healthy infants (195 isolates) were studied. The isolates from patients with SIDS were found to represent 119 different serotypes; the isolates from ‘other cause’ infants represent 97 different serotypes; and the isolates from healthy infants represent 117 different serotypes. The seven common serotypes isolated most frequently from infants with SIDS belonged to those associated with extra‐intestinal infections in humans. Compared to healthy infants (6%), these were found in significantly higher proportions among infants who died of other causes (13%, P < 0·05) or infants with SIDS (18·7%, P = 0·0002). Conclusions: Despite these sources yielding a wide variety of serotypes of E. coli, a pattern of certain potential pathotypes of E. coli being associated with SIDS is apparent. Significance and Impact of the Study: While SIDS remains one of the most important diagnoses of postneonatal death, its causes are still unexplained. If E. coli has a role in the pathogenesis of SIDS (as suggested by the pathotypes identified on the basis of serotype), further studies may reveal novel virulence factors that may clarify the role of this bacterium in SIDS.

“…From 1950 to July of 2009, 12 E. coli UTI outbreaks were identified, with the first outbreak reported in 1986 and the latest in 2008. Nine of these 12 outbreaks occurred in Europe, including two in the UK (Phillips et al, 1988; Woodford et al, 2004), three in Spain (Prats et al, 2000; Oteo et al, 2006; Blanco et al, 2009), and one each in Denmark (Olesen et al, 1994), Portugal (Mendonca et al, 2007), and Croatia (Vranes et al, 2008). Three other outbreaks were reported in North America, with two in the US (Kunin et al, 1993; Manges et al, 2001) and one in Canada (Pitout et al, 2005).…”

Urinary tract infections (UTIs) are among the most common bacterial infections worldwide. Disproportionately affecting women, UTIs exact a substantial public burden each year in terms of direct medical expenses, decreased quality of life, and lost productivity. Increasing antimicrobial resistance among strains of extraintestinal pathogenic Escherichia coli challenges successful treatment of UTIs. Community-acquired UTIs were long considered sporadic infections, typically caused by the patients’ native gastrointestinal microbiota; however, the recent recognition of UTI outbreaks with probable foodborne origins has shifted our understanding of UTI epidemiology. Along with this paradigm shift come new opportunities to disrupt the infection process and possibly quell increasing resistance, including the elimination of non-therapeutic antimicrobial use in food-animal production.
