Study found dust in daycare centers contained bacteria that could cause lung problems in children
Dust containing bacteria found in daycare centers could cause distress to children higher risk of asthmasuggests a new study from the European Respiratory Society.
In the study, researchers collected dust samples from 103 different daycare centers in Paris, France.
They then analyzed the samples in a laboratory to identify the bacteria they contained.
The researchers also asked the parents of 515 children to disclose whether the children suffered from wheezing or something similar Breathing problems.

Of the four types of bacteria found, one of them – including streptococci and lactococci – was associated with a higher risk of wheezing.
This is often a harbinger of asthma in children under the age of three, the diary entry says.

The average age of the children in the daycare centers tested was 2 years.
The results were presented at the International Congress of the European Respiratory Society in Milan, Italy, by Dr. Annabelle Bédard, a researcher at Inserm (the French National Institute of Health and Medical Research) in Paris, France.

“We find mixtures various bacteria and other microbes that live everywhere – outside, in our homes, on our skin and even in our bodies,” Bédard said in her talk. “These bacterial communities, known as microbiota, can have positive or detrimental effects on our health.”
She added: “Young children come into contact with the bacteria living in nurseries through their skin, their mouths and through inhalation. So we can assume that this contact will have an impact on the developing lungs of children through the different microbiota that arise in the respiratory tract, the intestines or the skin of children.”

These results highlight the need to further study indoor air quality in daycare centers, Bédard said.
“We now need to understand what factors influence this bacterial community – for example, how rooms are cleaned and ventilated and what the air quality is indoors,” she said.
“This, along with future findings from other studies, could help us understand how to improve and inform conditions Healthcare Strategies to prevent chronic respiratory diseases such as asthma in children.”

Researchers plan to track the health of the children in the study to determine which develop asthma as they age.
Dr. Steven Abelowitz, founder and medical director of Pediatrics for coastal children in California and also medical director of Pediatric Associates, was not involved in the study but reviewed the results.
He noted that some of the bacteria found in the study are quite common, while others are less common.
“We still have a lot to learn about these complex types of bacteria and how our body responds to them.”
“According to the study, at least two of the bacterial species (Streptococcus and Lactococcus) – which were the second most common bacteria they found – showed an association with a higher risk of wheezing in the study,” Abelowitz told Fox News Digital.
“We still have a lot to learn about these complex types of bacteria and how our body responds to them.”

While wheezing can be a sign or symptom of asthma, the doctor noted that this is not always the case.
“It really depends on how common and severe the wheezing is and whether it runs in the family History of allergiesAsthma and eczema,” he said. “Some studies have even shown that attending daycare in early childhood is inversely associated with wheezing and asthma.”
To minimize the risk of wheezing and other lung problems among children in daycare centers, a California doctor recommends keeping all rooms clean and well-ventilated and consistently monitoring indoor air quality. (iStock)

Abelowitz reiterated the need for further studies to explore these “complex bacterial communities” and their possible long-term association Lung problems in children.
He added, “From a pediatrician's perspective, it is more important to choose child care programs with low child-to-teacher ratios, small group sizes, well-trained staff, age-appropriate curricula and a safe, positive environment.”
