This week’s article examines the mechanisms by which vibration distorts airborne particle counter readings, why cleanroom conditions amplify these effects, the downstream risk to environmental monitoring, and mitigation strategies aligned to pharmaceutical expectations:

Airborne particle counters play a part in the contamination control strategy in pharmaceutical manufacturing, especially within Grade A and B environments where critical operations require continuous, accurate monitoring. These instruments use laser light to detect particles that pass through their

Antimicrobial tolerance is the ability of a normally susceptible, often dormant, bacterial population to survive, rather than die, during extended exposure to bactericidal drugs without changing their minimum inhibitory concentration (MIC). Unlike resistance, which allows growth despite drugs, tolerant bacteria temporarily endure treatment, leading to chronic, relapsing infections and potential evolution into resistant strains.



The following video provides some insights, looking at recent research

The Psychrobacter SC65A.3 bacterial strain isolated from Scarisoara Ice Cave, despite its ancient origin, shows resistance to multiple modern antibiotics and carries over 100 resistance-related genes.

The bacterium can also inhibit the growth of several major antibiotic-resistant 'superbugs' and shows important enzymatic activities with important biotechnological potential:

U.S. scientists have discovered a hidden molecular “switch” that herpes viruses rely on to invade cells. By combining AI, simulations, and lab experiments, the researchers identified and altered a single amino acid that shut down viral entry

AI-guided science revealed a tiny viral weak point—and shutting it down stopped infection cold.

Engineering Clostridium sporogenes to fight cancer. Researchers in Canada are engineering bacteria (Clostridium sporogenes) to invade tumours and consume them from the inside. Since tumour cores lack oxygen, they’re the perfect breeding ground for these microbes. The team added a genetic tweak that helps the bacteria survive longer near oxygen-exposed edges — but only once enough of them are present to trigger the change. It’s a carefully programmed biological attack that could one day offer a new way to destroy cancer. Read more here:

This week’s article looks at fungal growth and draws a distinction between filamentous fungi and yeasts, as well as growth requirements and growth rate differences between all fungi and bacteria. Why does this matter for drug research? Read on....

How can fungal growth be measured? To begin, there are differences between fungi classified as ‘yeasts’ and fungi classified as ‘filamentous’ (sometimes 'molds') Yeast typically exhibits faster, exponential growth (doubling in hours) compared to the slower, linear, tip-extension growth of fi...

This week’s article considers microbial salutogenics and why this emerging field is of potentially important interest for promoting human wellbeing:

The search for life on Earth is speeding up, not slowing down. Scientists are now identifying more than 16,000 new species each year, revealing far more biodiversity than expected across animals, plants, fungi, and beyond.
