The boys remain critically ill Monday at a Philadelphia hospital. Criminal investigators are examining how and why the bug killer got sprayed in a room beneath the family's rented villa two days before they arrived in mid-March.

The smell is caused by bacteria on the skin breaking down naturally secreted molecules contained within sweat. Now scientists have studied the underarm microbiome and identified a unique set of enzymes in the bacterium Staphylococcus hominis that is effective at breaking down sweat molecules into compounds known as thioalcohols, an important component of the characteristic body odor smell.
