Dust at day care centers contained bacteria that could cause lung issues in children, study found


Bacteria-containing mud found at day care centers could put kids at a higher risk of asthma, a brand new study from the European Respiratory Society suggests.

In the study, the researchers collected mud samples from 103 completely different day care services in Paris, France. 

Then they analyzed the samples in a lab to establish the bacteria found in each.

The researchers additionally requested the mother and father of 515 kids to reveal whether or not the youngsters skilled any wheezing or different respiratory issues.

Of the 4 forms of bacteria found, one in every of them — which included Streptococcus and Lactococcus — was linked to a better threat of wheezing.

That’s usually a precursor to bronchial asthma in kids underneath 3 years previous, the journal entry famous.

The common age of the youngsters in the examined day care centers was 2 years previous.

The findings had been introduced at the European Respiratory Society International Congress 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 of different bacteria and other microbes living everywhere — outside, inside our homes, on our skin and even inside our bodies,” Bédard mentioned in her presentation. “These communities of bacteria, known as microbiota, can have beneficial or harmful effects on our health.”

She added, “Young children will come into contact with the bacteria living in day care centers via their skin and mouths and by breathing them in. So, we might expect this exposure to have an impact on children’s developing lungs via the different microbiota that arise in children’s airway, gut or skin.”

These findings spotlight the necessity to additional examine indoor air high quality at day care centers, Bédard mentioned.

“We now need to understand what factors influence this bacterial community — for example, how the rooms are cleaned and ventilated, and indoor air quality,” she mentioned. 

“This, along with future findings from other studies, could help us understand how to improve conditions and inform public health strategies for preventing chronic respiratory diseases, such as asthma, in children.”

The researchers plan to comply with the well being of the youngsters in the study to find out which develop bronchial asthma as they get older.

Dr. Steven Abelowitz, founder and medical director of Coastal Kids Pediatrics in California and likewise medical director of Pediatric Associates, was not concerned in the study however reviewed the findings.

He famous that among the bacteria found in the study are fairly frequent, whereas others are much less frequent. 

“We still have a great deal to learn about these complex bacteria types and how our bodies respond to them.”

“Per the study, at least two of the types of bacteria (Streptococcus and Lactococcus) — which were the second most common bacteria they found — showed an association of a higher risk of wheezing in the study,” Abelowitz advised Fox News Digital. 

“We still have a great deal to learn about these complex bacteria types and how our bodies respond to them.”

While wheezing could be a signal or symptom of bronchial asthma, the physician famous that’s not all the time the case.

“It actually is determined by how frequent and extreme the wheezing is, in addition to if there’s a household history of allergies, bronchial asthma and eczema,” he mentioned. “Some studies have even shown that day care attendance in early childhood has been observed to be inversely associated with wheezing and asthma.”

Abelowitz reiterated the necessity for extra research to discover these “complex communities of bacteria” and their potential affiliation with long-term lung issues for children

He added, “From a pediatrician’s standpoint, it’s more important to choose childcare programs with low child-to-teacher ratios, small group sizes, well-trained staff, age-appropriate curriculum and a safe, positive environment.”
