Evaluation of apramycin activity against methicillin-resistant, methicillin-sensitive, and vancomycin-intermediate Staphylococcus aureus clinical isolates. Now online, congrats to Kat Truelson, see previous post.

Kat had a very productive undergraduate experience in the laboratory while attending Boston University as an undergraduate. Her first author manuscript titled: "Evaluation of Apramycin Activity Against Methicillin-Resistant, Methicillin-Sensitive, and Vancomycin-Intermediate Staphylococcus aureus Clinical Isolates" was just accepted into Diagnostic Microbiology and Infectious Diseases, more commonly referred to as DMID. Congratulations! She found that apramycin was equally active against MSSA, MRSA, and VISA strains, and demonstrated rapid time-kill kinetics. This manuscript expands apramycin's known activity spectrum to include contemporaneous human clinical strains of multidrug-resistant carbapenem=resistant Enterobacteriaceae = CRE; Acinetobacter baumannii, and Pseudomonas aeruginosa, and now Staphylococcus aureus.
We are very excited for Kat as she is moving this summer to the University of Chicago to work on a much beloved organism, Legionella pneumophila, in Howard Shuman's laboratory. Divya is freshman at Northeastern University and will be joining the laboratory to study novel antimicrobial treatment strategies. Her first project will involve collaboration with our Beth Israel Deaconess Medical Center and Harvard Medical School pathology colleague, Anders Berg.
Congratulations to lab members, Anthony Kang, and colleagues for our manuscript newly accepted in Antimicrobial Agents and Chemotherapy titled: "Efficacy of Apramycin against Multidrug-Resistant Acinetobacter baumannii in the Murine Neutropenic Thigh Model"
The manuscripts describes potent in vitro and in vivo activity of the apramycin, an aminocyclitol aminoglycoside, against multidrug-resistant and extensively-drug resistant Acinetobacter baumannii. In prior manuscripts, we demonstrated broad activity against several types of multidrug-resistant pathogens including carbapenem-resistant Enterobacteriaceae (CRE), Acinetobacter baumannii and Pseudomonas aeruginosa on Drug Development to Meet the Challenge of Antimicrobial Resistance, September 6-8, 2017. Posters were on apramycin, inkjet printer-based susceptibility testing methodology, and MAST rapid susceptibility technology, respectively.
