On admission to the hospital, his white blood cell count was 11,200 cells/mL (normal range: 4,000-10,000). Other laboratory tests evaluating hemoglobin, arterial blood gas, and levels of sodium, potassium, blood urea nitrogen, and creatinine were within normal limits. Abdominal radiography revealed numerous opaque shadows (arrows) in the stomach and intestine (Figure 1). What is your diagnosis?...

Candida albicans can stochastically switch between two phenotypes, white and opaque. Opaque cells are the sexually competent form of C. albicans and therefore undergo efficient polarized growth and mating in the presence of pheromone. In contrast, white cells cannot mate, but are induced - under a specialized set of conditions - to form biofilms in response to pheromone. In this work, we compar...

The differentiation of cells into distinct cell types, each of which is heritable for many generations, underlies many biological phenomena. White and opaque cells of the fungal pathogen Candida albicans are two such heritable cell types, each thought to be adapted to unique niches within their human host. To systematically investigate their differences, we performed strand-specific, massively-...
