Dysentery: Shigella, bacteria with adaptation to respiration

Imagerie montrant la déplétion de l'oxygène au sein de la muqueuse intestinale par Shigella (vert), induisant une hypoxie (rouge) au sein des foyers infectieux inflammatoires (neutrophiles: marqués à l'aide du Myelotracker, bleu).

Bacillary dysentery caused by the intestinal bacteria Shigella is a major health problem in tropical regions and developing countries. Complications from this infection lead to several hundred thousand deaths a year, primarily among infants. Researchers from Inserm and the Institut Pasteur have studied the mechanisms of Shigella virulence. They found that these bacteria are not only able to consume the oxygen in colonic tissue in order to grow and create foci of infection, but can also adapt their mode of respiration so that they can continue to grow once the oxygen in these foci has been used up.

Partially hydrolysed (hypoallergenic) baby formulas do not reduce allergy risks in infants

Hypoallergenic formulas are recommended for infants who are not exclusively breastfed and who are at risk of developing allergies. While it is assumed that such formulas reduce the development of allergies later in life, it is unclear whether this claim is true. A team of INRA and INSERM researchers have shown that the consumption of partially hydrolysed (hypoallergenic) formulas was not associated with a reduced risk of developing allergies, findings that were recently published in the journal Pediatric Allergy and Immunology.

When Moss Reflects Air Pollution

Despite the increasing research into and recognition of the role of particulate matter in the excess mortality caused by air pollution, it is still poorly understood. A research team used an innovative method based on the biomonitoring of metal levels in mosses in rural France. Their findings point to a link between long-term exposure to atmospheric metals and excess mortality, even in areas remote from major sources of emissions.

Better air quality: what should the target values be for improving health?

To produce a significant reduction in mortality due to fine particulates, their average level should be reduced by at least 3 micrograms per m3 as a yearly average, concludes an interdisciplinary study.
