Washington: You might not need to throw out your tooth brush after recovering from a sore throat after all, according to a new study.While some health care professionals tell patients - especially children - to replace their toothbrushes after suffering from a cold, the flu, or a case of strep throat, researchers from the University of Texas Medical Branch (UTMB) at Galveston advise that doing so might not be necessary.To determine whether the advice is warranted, the UTMB researchers tried to grow group A Streptococcus (GAS), the bacteria that causes strep throat, on toothbrushes that had been exposed to the bacteria in a laboratory. The bacteria did in fact grow and remained on the toothbrushes for at least 48 hours.Surprisingly, two new toothbrushes that were not exposed to GAS and served as controls also grew bacteria even though they had been removed from their packaging in a sterile fashion. An adult-size toothbrush grew gram-negative bacilli, and a child-size toothbrush grew gram-positive cocci, which was identified as Staphylococcus. Since this was not the main focus of the study, the researchers did not investigate this finding further.
