NewsSniffing out the cause of keratoderma-associated foot odor
The distinct foot odor that comes with the skin disorder Nagashima-type palmoplantar keratosis (NPPK) is caused by the overgrowth of a specific bacterial strain. Topical application of benzoyl peroxide restores balance in the bacterial skin flora, reducing the odor.

NewsResearch team identifies species of brucellosis-causing bacteria in Cameroon
Researchers have identified the specific species of the Brucella bacterium that causes illness in animals in Cameroon. A study of more than 4,600 livestock animals found that the only Brucella species present was Brucella abortus, a species primarily associated with cattle that causes pregnancy loss and infertility.
