The ability of bacterial populations to develop phenotypically heterogeneous subpopulations
has been recognized for decades. A recent study found that genetic hallmarks of …

Bacterial genomes evolve in complex ecosystems and are best understood in this natural
context, but replicating such conditions in the lab is challenging. We used transposon …

Alphaproteobacteria commonly produce an adhesin that is anchored to the exterior of the
envelope at one cell pole. In Caulobacter crescentus this adhesin, known as the holdfast, …

The opportunistic nosocomial pathogen Clostridioides difficile exhibits phenotypic heterogeneity
through phase variation, a stochastic, reversible process that modulates expression. In …

Bacteria are often attached to surfaces in natural ecosystems. A surface-associated lifestyle
can have advantages, but shifts in the physiochemical state of the environment may result in …

Bacterial genomes are the products of selection in fluctuating, spatially heterogeneous, and
often nutrient-poor environments. Thus bacterial gene function is best understood in this …

manuscript was published in PLoS Genetics in May 2019 (DOI: 10.1371/journal.pgen.1008022). …

Sporothrix schenckii, now named the S. schenckii species complex, has largely been
known as the etiological agent of sporotrichosis, which is an acute or chronic subcutaneous …

… Leila, thank you for giving me so much strength and for going through the graduate school
eRperience together with me. I am so proud of who you are, and I thank you for all your love …

Background The fungal genus Sporothrix includes at least four human pathogenic species.
One of these species, S. brasiliensis, is the causal agent of a major ongoing zoonotic …
