What are the real threats of bioterrorism?

What are the real threats of bioterrorism?

We have already mentioned that the concept of weapons of mass destruction tends to be replaced by that of weapons of mass disruption (NBC-NRBce). After a new study of the bibliography, it appears that biological weapons are evolving very rapidly with new technologies and in particular those allowing genome manipulation: these new data are shaking…

One bag may hide another: the evacuation bag, the CBRN patient transport stretcher, the CBRN body bag.

One bag may hide another: the evacuation bag, the CBRN patient transport stretcher, the CBRN body bag.

When a CBRN event occurs and there are casualties, the problem of transporting victims arises. At the same time as first aid must be administered, care must take into account the fact that these victims can contaminate their surroundings and cause cross-contamination, the dramatic consequences of which could be measured during the sarin gas attack…

Engineering the gut microbiome to optimize warfighter performance

A recent article shows us that American researchers are interested in the intestinal microbiome of war fighters in order to improve their performance on missions. Microbiomes et microbiota The microbiome is the place where a complex set of microorganisms called microbiota develops. In humans, microbiomes from the nose/mouth/throat, skin, lungs, digestive system and vagina are…
