A "bacterial zoo" with microscopic cages has been built out of jelly by US researchers. Their findings, published in Proceedings of the National Academy of Sciences, could transform understanding of how bacteria behave in communities.
The Food Standards Agency, with Public Health England and local authorities, is investigating an outbreak of a particular strain of salmonella, called Salmonella Gold-coast, which is known to have caused 18 cases of illness.
This report, Antibiotic resistance threats in the United States, 2013 gives a first-ever snapshot of the burden and threats posed by the antibiotic-resistant germs having the most impact on human health.
By Susan Golden If one were to ask, “What happens when Salmonella infects the gut?” it might not be obvious that you’d also need to ask, “What time is it?” But indeed you’d need to know the latter to appropriately address the former.
Iain Haysom's insight:
This research indicates that the body's inflammatory response to Salmonella infection may be affected by the timing of infection.
Microbiology, we will agree, is a vast subject where many important aspects are likely to evade one’s sight. Here’s an example—the formation of vesicles from the outer membrane of Gram-negative bacteria.
by Melissa Wilks Every day we see animals migrating through the air, across plains, and in the oceans, in beautifully coordinated patterns; starlings flock together in the thousands while sardines swim together in enormous shoals. But what about smaller organisms?
The human genome codes for approximately 23,000 genes, yet some experts have suggested that the total information coded by the human genome alone is not enough to carry out all of the body’s biological functions. A growing number of studies suggest that part of what determines how the human body functions may be not only our own genes, but also the genes of the trillions of microorganisms that reside on and in our bodies.
Sainsbury’s is recalling all of its bagged watercress and salads containing watercress as a precautionary measure, due to a possible association with an outbreak of E.coli O157 that has made 15 people ill.
An outbreak of an unusual type of salmonella infection, Salmonella Typhimurium, across England and Wales is being investigated by Public Health England, Public Health Wales, the FSA and local authority environmental health officers.
