# A Case of New Delhi Metallo-ß-Lactamase-Producing Enterobacter and a Review of Cases in the United States From January 2009 to September 2022

## TL;DR

This paper reports a case of antibiotic-resistant Enterobacter in a U.S. patient and reviews similar cases from 2009 to 2022.

## Contribution

The study adds a new U.S. case of New Delhi Metallo-β-Lactamase-producing Enterobacter and reviews prior reports.

## Key findings

- A carbapenem-resistant Enterobacter cloacae complex was identified in a Texas patient.
- The study highlights the importance of infection control and antimicrobial stewardship.
- It reviews at-risk populations and treatment options for resistant organisms.

## Abstract

Antimicrobial resistance is a growing problem. Novel resistance mechanisms continue to emerge, and the pipeline of antimicrobial development struggles to keep up. Antimicrobial stewardship and proper infection control are key in preventing the spread of these infections. A case of a carbapenem-resistant Enterobacter cloacae complex urinary isolate was identified in an 81-year-old male patient at the San Antonio Veterans Affairs hospital, Texas, USA. The patient was placed on isolation, and further testing of the isolate to other antibiotics requested. The purpose of this study is to analyze the details of reports of such cases and to review at-risk populations and appropriate treatment for resistant organisms.
