Background: Uropathogenic Escherichia coli (UPEC) has increased the incidence of urinary tract infection (UTI). It is the cause of more than 80% of community-acquired cystitis cases and more than 70% of uncomplicated acute pyelonephritis cases. Aim: The present study describes the molecular epidemiology of UPEC O25b clinical strains based on their resistance profiles, virulence genes, and genetic diversity. Methods: Resistance profiles were identified using the Kirby–Bauer method, including the phenotypic production of extended-spectrum β-lactamases (ESBLs) and metallo-β-lactamases (MBLs). The UPEC serogroups, phylogenetic groups, virulence genes, and integrons were determined via multiplex PCR. Genetic diversity was established using pulsed-field gel electrophoresis (PFGE), and sequence type (ST) was determined via multilocus sequence typing (MLST). Results: UPEC strains (n = 126) from hospitalized children with complicated UTIs (cUTIs) were identified as O25b, of which 41.27% were multidrug resistant (MDR) and 15.87% were extensively drug resistant (XDR). The O25b strains harbored the fimH (95.23%), csgA (91.26%), papGII (80.95%), chuA (95.23%), iutD (88.09%), satA (84.92%), and intl1 (47.61%) genes. Moreover, 64.28% were producers of ESBLs and had high genetic diversity. ST131 (63.63%) was associated primarily with phylogenetic group B2, and ST69 (100%) was associated primarily with phylogenetic group D. Conclusion: UPEC O25b/ST131 harbors a wide genetic diversity of virulence and resistance genes, which contribute to cUTIs in pediatrics.

Acute myocarditis is a rare complication of Escherichia coli urinary tract infection and sepsis. We report the case of a previously healthy 55-year-old female who presented to our emergency department with diarrhea and hypotension. The basic metabolic panel results showed an increase in inflammatory markers and an acute kidney injury. Urine and blood cultures grew Escherichia coli. The patient subsequently developed sudden chest pain and shortness of breath, diffuse ST-segment elevation, and cardiac enzymes’ elevation. Coronary angiogram was normal, and transthoracic echocardiogram demonstrated normal ventricular functions. Cardiac magnetic resonance imaging was highly suspicious of myopericarditis. The patient made a full recovery after infection treatment with intravenous antibiotics, aspirin, and colchicine.
