Differential filamentation of Candida albicans and Candida dubliniensis Is governed by nutrient regulation of UME6 expression.

Candida dubliniensis is closely related to Candida albicans; however, it is responsible for fewer infections in humans and is less virulent in animal models of infection. C. dubliniensis forms fewer hyphae in vivo, and this may contribute to its reduced virulence.

Distribution, localization, and phylogeny of abundant populations of Crenarchaeota in anaerobic granular sludge.

Eight anaerobic granular sludges were surveyed for Crenarchaeota using rRNA gene cloning. Microbial arrangement and substrate uptake patterns were elucidated by fluorescent in situ hybridization and beta imaging. Group 1.
