Be aware of Shiga-toxin 2f-producing Escherichia coli: case report and false-negative results with certain rapid molecular panels.

We report a hemolytic uremic syndrome (HUS) case due to Stx2f-producing E. coli illustrating the diagnostic difficulty of this Shiga-toxin subtype. Clinicians should be aware of limits of certain rapid molecular panels that are increasingly being used and may play a role in underestimating the global burden of such infections.

Antimicrobial resistance in community-acquired urinary tract infections in Paris in 2015.

Background: Urinary tract infection (UTI) is one of the most frequent community-acquired infection. Escherichia coli resistance has been on the rise since 2000s.

Methods: We conducted a prospective multicenter cohort study including adults who had a positive urine cytobacteriological examination (UCBE) performed in our Parisian suburb laboratory platform from October 2014 to March 2015.

Staphylococcus aureus nasal and pharyngeal carriage in Senegal.

Nasal and pharyngeal swabs were collected from 132 patients admitted to the Principal Hospital in Dakar (Senegal), in January and February 2012. The prevalence of Staphylococcus aureus carriage was 56.1% (n = 74): 40.

Klebsiella pneumoniae resistant to third-generation cephalosporins in five African and two Vietnamese major towns: multiclonal population structure with two major international clonal groups, CG15 and CG258.

The molecular epidemiology of third-generation cephalosporin-resistant (3GC-R) Klebsiella pneumoniae in developing countries is poorly documented. From February 2007 to March 2008, we collected 135 3GC-R K. pneumoniae isolates from seven major towns in Maghreb (Morocco), West Africa (Senegal, Côte d'Ivoire), Central Africa (Cameroon), East Africa (Madagascar) and Southeast Asia (Vietnam).
