Type VI secretion system activity at lethal antibiotic concentrations leads to overestimation of weapon potency Competition assays are a mainstay of modern microbiology, offering a simple and cost-effective means to quantify microbe–microbe interactions in vitro. Here, we demonstrate a key weakness of this meth...

Does your lab perform killing assays?
TL;DR: we’ve identified a problem that can bias the outcome of killing assays, making antagonism look stronger than it really is.
Adding a simple extra step can mitigate this bias!

Peptidoglycan–outer membrane attachment generates periplasmic pressure to prevent lysis in Gram-negative bacteria - Nature Microbiology Outer membrane attachment to peptidoglycan enables periplasmic pressure to build up and counter cytoplasmic turgor pressure, preventing lysis during osmotic challenges in Escherichia coli.

Two photos of Sri Lankan flameback woodpeckers on tree trunks. On left: a yellow-backed flameback (Dinopium benghalense) in northern Sri Lanka. On right: a red-backed flameback (Dinopium psarodes) in southern Sri Lanka. Both birds have red crests on top of the head, black and white stripes on the head and neck, brightly coloured backs, and stiff black tails that help to hold them upright on the tree trunks.

AMRrules encodes in a simple table format: In this species, if we find this gene/mutation, then we expecte this drug phenotype, based on this evidence.

AMRrules encode organism-specific rules for interpreting AMR genotype calls: if I find this gene/mutation in this organism, what does it mean for clinical resistance?

For a good start into 2025 we offer a small treat 🎁 (preprint) to quantitative proteomics and predatory bacteria 🦠 researchers. Our predatory proteome of B.bacteriovorus offers high temporal resolution (based on n=5 biological repeats!) for a better understanding of the killing process. #MicroSky

As an international student I put all eggs in one basket and applied to my dream PhD in the US and got rejected after the interviews. They did not mention fund cuts as the reason. Bt I suspect that. It took me a while bt I picked myself up (I think) to go forward!

Yup! This is not talked about enough and there is no answer for that. For me it's if "A" happens by "X" it will be "B". If it's "C", then "D" and "E". Anyways no regrets!

The moment my MSc PI professor, decided to give me a chance to join his group. I was an international student, only female graduate student of the group. This opened a whole new world for me. He gave me the confidence to dream.

Cool, nice chart! I have made a similar one showing also commercialization and resistance.
Interestingly, resistance was sometimes observed before market introduction.
