Inhale agricultural dust affects intestinal:
Essential
- According to a new study conducted on mice, the inhalation of agricultural dust has impacts the intestinal microbiota. Nevertheless,
- The researchers observed a decrease in the good bacteria present in the microbiota. Consequently, the concentrations of certain essential compounds in the intestine. Moreover,
- The permeability of the intestinal barrier was also more important. Similarly, which is associated with various chronic pathologies such as type 1 diabetes. Meanwhile,
The air you breathe on the farm does not only affect the lungs. Meanwhile, According to a new study published in the journal Journal of Applied Toxicologyinhaling dust of farms can also have heavy repercussions on our intestinal health.
Decrease in good intestinal bacteria – Inhale agricultural dust affects intestinal
During previous work, scientists inhale agricultural dust affects intestinal had already shown the impact of agricultural dust on pulmonary health. Exposure was linked to a risk of pulmonary inflammation. “” “Exposure to porcine farming dust, rich in bacteria and endotoxinescaused inflammation of the respiratory tract and a greater passage of intestinal bacterial products in the bloodstream in our mouse modelsexplains Meli’sa Crawford, first author of the study, in a communiqué. But what is particularly striking is the impact we have observed on the intestinal microbiome and metabolism.”
During these new works, scientists have exhibited rodents, for three weeks and intranasal means, to a sample of dust from a pig farming. Their study therefore focused on the consequences on intestinal health and microbiota.

“Agricultural dust is rich in fine particles and resistant bacteria, with a complex inhale agricultural dust affects intestinal threat to agricultural workers’ health, Details Declan McCole, one of the authors. Our previous work has shown that the extract of inhaled pork dust leads to neutrophilic pulmonary inflammation. We now show the link with the dysfunction of the intestinal barrier. microbial imbalance, emphasizing the need to improve protections in terms of workplace for agricultural workers to mitigate the long -term health consequences.”
In detail, scientists obtained the following results in mice:
- Decrease in good bacteria present in the microbiota.
- Lower concentrations of certain essential compounds present in the intestine, such as riboflavin (vitamin B2) or leucine, an amino acid.
- Increased permeability of the intestinal barrier, which is associated with various chronic pathologies, including chronic inflammatory diseases of the intestine (Small), gluten intolerance and the Type 1 diabetes.

Air pollution affects the microbiota
“While most research has focused on the respiratory effects of agricultural dust, our results clearly show that inhaled pollutants can have systemic consequencesindicates Declan McCole. [Celles-ci] Underline the importance of taking into account the intestine-poumons axis during the assessment of health risks linked to exposure to bioaérosols in agriculture.”Better knowing these risks would also make it possible to better protect the agricultural workers exposed to it.
Other studies have already highlighted the impact of air pollution on the microbiota. In works published in 2020 in the journal Environment Internationalscientists showed in particular that ozone, an air pollutant, altered the composition inhale agricultural dust affects intestinal and the function of the intestinal flora.
