Researchers Study Possible Bacterial Link to SIDS

LONDON —  A baffling phenomenon known as sudden infant death syndrome is one of the leading causes of death for children under 1. Now, British researchers say they may have found a contributing factor: bacteria.

They found potentially dangerous bacteria such as Staphylococcus aureus and E. coli in nearly half of all babies who died suddenly and without explanation over a decade at a London hospital. Their findings are in Friday's Lancet medical journal.
