OverviewAI-generated summary

Anna L. F. V. Assumpcao's research investigates the complex interplay between host factors, the microbiome, and immune responses in chickens. Her work explores how environmental stressors, such as cold stress, and dietary interventions influence gut health and pathogen carriage. She has examined the impact of specific feed additives, like trans-cinnamaldehyde and caprylic acid, on reducing foodborne pathogens, as well as the effects of natural compounds such as garlic, ginger oil, and eugenol nanoemulsion on controlling Salmonella and Campylobacter.

Her publications also delve into the immunological aspects of chicken health, including the co-evolution of humoral immunity and the serotonergic system, and the effects of Salmonella colonization on leukocyte populations. Assumpcao has also investigated the efficacy of novel vaccine approaches, such as an electron-beam-killed Staphylococcus vaccine, in reducing lameness in broiler chickens. Her research network includes collaborators from the University of Arkansas at Fayetteville, with whom she has co-authored multiple publications.
