Longer allergy tests may breed superbugs in Kids' guts

This study looked at whether giving children a longer oral drug challenge test for penicillin-like antibiotics (to confirm an allergy) increases the chance of resistant bacteria growing in their gut. Fifty children aged 0-18 with mild, delayed allergic reactions were tested. The researchers compared short (1-4 days) and long (5-8 days) test protocols by checking rectal swabs before and after for extended-spectrum beta-lactamase-producing bacteria. The goal was to understand if longer testing raises the risk of antibiotic resistance.
