OverviewAI-generated summary

Anna L. F. V. Assumpcao's research focuses on the interplay between host physiology, the microbiome, and immune responses in chickens, particularly in the context of foodborne pathogen reduction and health. Her work has investigated how environmental factors, such as cold stress, influence the chicken gut microbiome and host neurochemistry, specifically serotonin and catecholamines.

Assumpcao has explored the effects of feed additives, including trans-cinnamaldehyde, caprylic acid, garlic, and ginger oil, on reducing foodborne pathogens like Salmonella and Campylobacter. Her studies also examine the genetic selection for immune responses, such as antibody titer, and its impact on the gut microbiome and serotonergic systems. Collaborations include researchers from the University of Arkansas at Fayetteville, with whom she has co-authored multiple publications. Her scholarship metrics include an h-index of 5 and 12 total publications.
