    250: Metallo-β-Lactamases: The Rise of NDM and Beyond

    Metallo-β-lactamases (MBLs) have become an increasingly important topic in clinical microbiology and infectious diseases. While these enzymes were once encountered relatively infrequently in the United States, their epidemiology is changing, with NDM-producing organisms becoming more common. What makes metallo-β-lactamases different from other carbapenemases? Why are infections caused by MBL-producing organisms particularly challenging to treat? And what new treatment options are becoming available? In this episode of Let's Talk Micro, Luis is joined by Dr. Ryan Shields and Dr. Emily Heil to discuss metallo-β-lactamases and their growing clinical significance. They explore the differences between serine β-lactamases and MBLs, review important enzymes such as NDM, VIM, and IMP, and discuss the challenges associated with treating infections caused by MBL-producing organisms. The conversation also covers emerging treatment options, including aztreonam-avibactam and cefepime-zidebactam, and highlights the importance of identifying specific carbapenemases to guide antimicrobial therapy. Join us for a discussion on the evolving landscape of metallo-β-lactamases and the essential role of the clinical microbiology laboratory in patient care.

    248: Micro Minutes: What's in a name- Bacterial Groups and Complexes

    Have you ever performed an organism identification using MALDI-TOF mass spectrometry and received a result showing multiple possible species, such as Enterobacter cloacae and Enterobacter asburiae, or Citrobacter freundii and Citrobacter werkmanii? Why does this happen? What do these organisms have in common, and why are they classified into groups or complexes? In this episode of Micro Minutes, Luis explores bacterial groups and species complexes, why they exist, and how they relate to organism identification. He discusses several familiar and lesser-known examples, including the Enterobacter cloacae complex, Acinetobacter calcoaceticus–baumannii complex, Klebsiella pneumoniae species complex, Citrobacter freundii complex, and Pseudomonas putida group. The episode also highlights the Burkholderia cepacia complex and why species-level identification can be particularly important in patients with cystic fibrosis. Finally, learn why reporting an organism at the group or complex level is often appropriate, when additional identification may be necessary, and why understanding the capabilities and limitations of your identification system matters.

    Have you ever received an identification result that just didn't make sense? In this episode, Luis shares three cases of mistaken identity from the microbiology laboratory: a Gram-positive rod identified as Kocuria, another reported as Sphingomonas, and a yeast that somehow became Brucella. While automated identification systems are powerful tools, they can only work with the information we provide. These examples highlight an important lesson for every microbiologist: always correlate the identification with the Gram stain, colony morphology, and other bench observations. When the result doesn't fit, take a step back and ask a simple question: Does it make sense? Join us for a quick Micro Minutes on critical thinking, correlation, and why the Gram stain remains one of the most valuable tools in the microbiology laboratory.
