Bruna is a veterinary microbiologist specializing in host-microbiota interactions and infectious diseases. Her current research focuses on understanding the role of microbial communities in animal health, with particular emphasis on Peptacetobacter hiranonis and its involvement in bile acid metabolism in dogs and cats. Bruna has contributed to veterinary science by publishing research on intestinal and oral microbiota, zoonotic pathogens, and infectious diseases across multiple species, including dogs, cats, horses, pigs, and wild animals. Her studies include investigations of bacterial intestinal dysbiosis in chronic enteropathies, and the comparative microbiome in canine and feline health and disease. In addition to microbiome research, Bruna has conducted work on bacterial pathogens, including Salmonella spp., Streptococcus suis, and Mycobacterium species, addressing issues such as antimicrobial resistance, molecular diagnostics, and pathological characterization of infections. Her expertise also includes biofilm formation, bovine mastitis, and respiratory diseases in domestic and wild animals. Bruna has published peer-reviewed publications in journals such as Animals, PLOS ONE, Current Microbiology, Brazilian Journal of Microbiology, Pesquisa Veterinária Brasileira, Journal of Comparative Pathology, Preventive Veterinary Medicine, Tropical Animal Health and Production, Virology, Molecular Biology Reports, Diseases of Aquatic Organisms, Ciência Rural, and others.
