Prof. Anat Herskovits

Anat Herskovits is investigating host-pathogen and pathogen-phage interactions. She uses the intracellular bacterial pathogen Listeria monocytogenes to explore how temperate phages that stably inhabit the genome affect bacterial virulence, and how they are adapted to the mammalian environment. Further she explores the interactions between cohabiting phage elements, and how polylysogeny is maintained. While most bacterial pathogens, and bacteria in general, are lysogens, namely carry DNA of infective and cryptic phage elements in their genome, their impact on the behavior of bacterial pathogens during mammalian infection is not well understood. Anat investigates these  questions, focusing on bacteria-phage cooperative behaviors that support virulenc
