MIC and Upper Limit of Wild-Type Distribution for 13 Antifungal Agents against a Trichophyton mentagrophytes-Trichophyton interdigitale Complex of Indian Origin.

Dermatophytosis due to the complex is being increasingly reported across India. Reports of therapeutic failure have surfaced recently, but there are no clinical break points (CBP) or epidemiological cutoffs (ECVs) available to guide the treatment of dermatophytosis. In this study, a total of 498 isolates of the complex were collected from six medical centers over a period of five years (2014 to 2018).

Misidentification of a commensal inactive Escherichia coli as Shigella sonnei by an automated system in a critically ill patient.

Background: Though automated identification and sensitivity testing has established itself as a standard in many high throughput clinical microbiology laboratories, misidentification by the automated systems can also happen.

Case Report: Here we present a case of sepsis, caused by a commensal inactive Escherichia coli, which had been repeatedly misidentified as Shigella sonnei by VITEK 2 compact.

Conclusions: The laboratory worker should always be aware of possible misidentification and limitations of automated systems.
