A study conducted at the University of Helsinki found an abundance of diverse fungal microbiota in infant guts treated with antibiotics in comparison to the control group after a six-week regimen of antibiotics. The finding published in the Journal of Fungi highlighted the increase in gut space caused by antibiotic treatment, thus, reducing the competition for fungal species and helping them multiply.

The study emphasized that imbalanced microbial events can lead to antibiotic-associated diarrhoea, chronic inflammatory disease, IBD, obesity, etc. The study was a comparison between respiratory syncytial virus (RSV) infection in infants who had never received any antibiotics and the ones who were given antibiotics due to complications.

Rebecka Ventin-Holmberg, a Ph.D. student at the institution stated that the findings of the study determined that gut bacteria regulate and control the fungal microbiota. The bacterial biome balance is disturbed by antibiotic therapy, Fungal species such as Candida replicate in multiple folds. These changes in bacteria-fungi microbiota balance hurt our health in a long run.
