"Stalking the elusive generalist: Pseudomonas in the home"

Dr. Sussana Remold Dr. Sussana Remold
University of Louisville

Dr. Remold works on the evolution of microbes, in particular ones associated with human disease. Currently her lab focuses on bacteria in the genus Pseudomonas from human homes and from the people and pets living in them. Her team combine studies of the distributions of these organism, studies of their patterns of phenotypic variability, and investigations of the genetic underpinnings of these phenotypes, and the evolutionary pressures that help mold them.

They have sampled human homes for many years, looking for members of the genus Pseudomonas. They have found that recovery of these bacteria varies among houses, among types of places within houses, as well as among seasons. They have also found that the opportunistic pathogen Pseudomonas aeruginosa is found most frequently in drains, rather than being widespread around the home. This is important because it suggests that for susceptible people, such as immunocompromised people or people with cystic fibrosis, controlling exposure to P. aeruginosa in drains may be an important contributor to decreasing the risk of infection. .
