U01.03.008 Urease-positive organisms Urease-positive organisms produce the enzyme urease, which hydrolyzes urea into ammonia and carbon dioxide, increasing the pH of their environment. This enzyme aids bacterial survival and virulence, especially in the urinary tract and stomach. Common urease-positive organisms include Proteus, Klebsiella, Helicobacter pylori, Ureaplasma, Nocardia, Cryptococcus, and Staphylococcus saprophyticus.

U01.03.005 Anaerobes Anaerobes are bacteria that thrive in environments lacking oxygen. They are part of normal flora but can cause disease when introduced into sterile sites. Key anaerobes include Clostridium, Bacteroides, Fusobacterium, and Actinomyces, known for producing foul-smelling infections and gas formation.

Highlights from the TrEE team. Yesterday, at Les 3 Sommets hotel (Col de Porte, Chartreuse), we gathered for an inspiring day focused on bacterial metabolism evolution and engineering. Happy faces of everyone 🤩
