In vitro activity of an aqueous allicin extract and a novel allicin topical gel formulation against Lancefield group B streptococci.

Background: Studies have shown the efficacy of intra-partum antibiotics in preventing early-onset group B streptococcal sepsis. This approach results in a high intra-partum antibiotic use. Worryingly, the same antibiotics used in prophylaxis are also first-line treatment for neonatal sepsis, and antibiotic exposure in the peri-natal period has been shown to be a risk factor for late-onset serious bacterial infections and allergic disease.

Preventing airborne infection with an intranasal cellulose powder formulation (Nasaleze travel).

A total of 52 volunteers were recruited to take part in a dual-centered, randomized, blinded study so investigators could determine whether the level of airborne infection could be significantly reduced in patients randomly assigned to treatment with either Nasaleze cellulose extract alone or a combination of Nasaleze cellulose and powdered garlic extract (PGE). One puff into each nostril was recommended, and volunteers who developed an infection while traveling were told to use at least 3 puffs per nostril until symptoms were reduced. This study took place over an 8-wk period across Finland and the United Kingdom between November 2006 and March 2007.
