Discordant Susceptibilities of Enterobacterales to Different Tetracycline Classes.

When bacteria are tetracycline- or doxycycline-resistant, the ability of these bacteria to be susceptible to the other tetracyclines is not well defined. Consequently, gaining knowledge about the ability to infer Enterobacterales susceptibility to minocycline and third-generation tetracycline antibiotics from surrogates is vital. In this study, we show that tigecycline may be a reasonable surrogate from which clinicians can infer omadacycline and eravacycline susceptibilities, even in the presence of doxycycline and tetracycline resistance.

Defining the value of medical microbiology consultation.

Unlabelled: Medical microbiologists, defined as doctoral-level laboratory directors with subspecialty training in medical microbiology, lead the clinical laboratory operations through activities such as clinical consultations, oversight of diagnostic testing menu, institutional leadership, education, and scholastic activities. However, unlike their clinical colleagues, medical microbiologists are largely unable to bill for clinical consultations performed within the hospital and, therefore, unable to generate relative value units or a similar quantifiable metric. As hospital budgets tighten and justification of staffing becomes a necessity, this may present a challenge to the medical microbiologist attempting to prove their value to the organization.
