Congratulations to Anthony Kang, PhD, and colleagues on our publication: "In Vitro Apramycin Activity Against Multidrug-Resistant Acinetobacter baumannii and Pseudomonas aeruginosa" published online today in Diagnostic Microbiology and Infectious Disease
The manuscript highlights the remarkable activity of apramycin against multidrug-resistant, extensively drug resistant and pandrug-resistant Acinetobacter and Pseudomonas. Both organisms are significant multidrug-resistance threats. Importantly, frank resistance to apramycin was observed in < 2% of isolates. Apramycin is an aminocyclitol-based aminoglycoside that is currently approved for veterinary use. The activity in these groups of bacteria was especially notable in light of the high level of resistance of the same strain set to aminoglycosides (amikacin, gentamicin, tobramycin) approved for human use. This study complements our prior study, also published in DMID, demonstrating activity of apramycin against a high proportion of carbapenem-resistant Enterobacteriaceae strains.
Congratulations to Postdoctoral Fellow Yoon-Suk Kang on publication of his manuscript "Promotion and Rescue of Intracellular Brucella neotomae Replication During Co-Infection With Legionella pneumophila"
Published online today in Infection and Immunity: "Promotion and Rescue of Intracellular Brucella neotomae Replication During Co-Infection With Legionella pneumophila." Yoon-Suk created a versatile bioreporter toolkit to enable analysis of the fate of individual pathogens in polymicrobial infections. He then validated a type IV secretion system-dependent Brucella model using the wood rat pathogen, Brucella neotomae. In contrast to wild type organisms, Brucella T4SS mutants were completely defective in their ability to growth inside of macrophages. Fascinatingly co-infection with Legionella pneumophila, another T4SS-dependent pathogen, was able to rescue intracellular growth of the T4SS-mutant Brucella and also stimulated growth of wild type Brucella organisms! This was a one way rescue: Legionella could rescue Brucella, but wild type Brucellla could not rescue T4SS-defective Legionella.
Our antimicrobial susceptibility testing research is highlighted on Harvard Catalyst Spotlight

Congratulations to Thea Brennan-Krohn and KP Smith for being awarded ASM Travel Awards
Thea received an ASM Infectious Disease Travel Award and KP Smith an ASM Postdoctoral Travel Award. Both prestigious ASM Travel Awards are based on abstract submissions to the 2017 ASM MIcrobe Meeting in New Orleans. Jennifer Tsang will be joining the crew with an abstract acceptance on her high throughput screening work..
We are competing in the STAT Madness competition for Innovations in Biomedical Science. Please vote for us!!!!
