Bio Summary

Barbara is a Brazillian veterinarian with a Master of Science degree in veterinary pathology from the Universidade Federal de Minas Gerais. 

Upon graduation, Dr. Cortez worked at the WCVM as a visiting research student performing research on non-antibiotic alternatives for swine dysentery using an in vitro approach, then moved to the Vaccine and Infectious Disease Organization (VIDO) as a research assistant, optimizing the in vitro culture of the vaccinal strain of Lawsonia intracellularis

Research Area(s)

Streptococcus equi subsp. zooepidemicus (S. zoo) is considered a commensal and opportunistic pathogen of several warm-blooded hosts, including pigs. It can cause severe disease characterized by pneumonia, septicemia and meningitis. S. zoo has been indicated to be a normal flora of the palatine tonsils of pigs. However, virulent strains of S. zoo reportedly killed over 300,000 pigs in the 1970s and it is associated with high-mortality outbreaks of sudden death and respiratory disease in pigs in China. Currently, there are no commercial vaccines available. The overarching goal of the work proposed here is to develop tools to control of S. zoo infection in pigs, to reduce disease severity, and to develop vaccines to prevent infection.
