Molecular epidemiology of Escherichia coli producing CTX-M β-lactamases: the worldwide emergence of clone ST131 O25:H4

Peirano, Gisele, Pitout, Johann D.D.·2010·International Journal of Antimicrobial Agents

Abstract

Since 2000, Escherichia coli producing CTX-M enzymes have emerged worldwide as important causes of community-onset urinary tract and bloodstream infections owing to extended-spectrum beta-lactamase (ESBL)-producing bacteria. Molecular epidemiological studies suggested that the sudden worldwide increase of CTX-M-15-producing E. coli was mainly due to a single clone (ST131) and that foreign travel to high-risk areas, such as the Indian subcontinent, might in part play a role in the spread of this clone across different continents. Empirical antibiotic coverage for these resistant organisms should be considered in community patients presenting with sepsis involving the urinary tract, especially if the patient recently travelled to a high-risk area. If this emerging public health threat is ignored, it is possible that the medical community may be forced, in the near future, to use carbapenems as the first choice for the empirical treatment of serious infections associated with urinary tract infections originating from the community.

  • The molecular epidemiology of ESBL-E enzymes identified in the Madagascar, Nigeria, Cameroon, and Mozambique studies was in keeping with the global predominance of the CTX-M clone.

    “The molecular epidemiology of the ESBL-E enzymes identified in the Madagascar (Chereau et al., 2015), Nigeria (Fortini et al., 2015), Cameroon (Djuikoue et al., 2016b), and Mozambique (Sáez-lópez et al., 2016) studies was in keeping with the global predominance of the CTX-M clone, which is also widely reported in community-acquired UTI (Pitout et al., 2005;Peirano and Pitout, 2010;Pallecchi et al.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
