Excited to highlight our new work in #mbio showing how an A. baumannii type VI secretion system effector functions and is delivered. Awesome work by @Vali_Bez , Brooke Hayes @Cescagillett , Amy Wright @davidroper2 @DrSheenaMcGowan and Marina Harper journals.asm.org/doi/10.1128…

Delivery determinants of an Acinetobacter baumannii type VI secretion system bifunctional peptido...

We have shown that the Acinetobacter baumannii T6SS effector Tae17 is a modular, bifunctional, peptidoglycan-degrading enzyme that has both lytic transglycosylase and amidase activities. Both...

Why is a possible lockdown later better than earlier? #qanda

At current growth of Aus Covid-19 infections (doubling every 3.7 days) we have 23 days till ICU beds over capacity (5% infections requiring ICU, 2200 ICU places, 4 day doubling). Will current unclear, mostly optional restrictions halt this? #COVIDー19 #Lockdownaustralia
Reporters ask government 1. Why it’s better to shut down later than early? 2. What expert advice relying on (make predictions public) and what level of infections/deaths are in models? 3. Why full lockdown needs 6 mnths when disease period 3 wks #COVIDー19 #Lockdownaustralia
