The PPGBA has an international network of partners composed of researchers from various universities in Europe, North America, and South America. These actions took place throughout the four-year period with countries such as Canada, Denmark, Sweden, Belgium, Argentina, Spain, the United States, France, Portugal, among others. Actions related to institutional agreements are encouraged by the Graduate Studies Office.

Currently, the Program has a student from Peru (OAS/GCUBUFRPE Agreement) and a student from Ecuador who joined in 2019. In 2018, UFRPE participated in the Capes-PrInt call, and PPGBA had its project approved within the institutional context, beginning its activities in 2019. Within the institutional internationalization project, PPGBA focused on two strategic themes: Theme 1. Agricultural production systems, biodiversity, and sustainability: Objective Title: Epidemiology, development, and standardization of diagnostic techniques for diseases. Theme 2. Future-bearing technologies (Nanotechnology). Objective: To develop and characterize systems for the controlled release of drugs at the nanoscale for veterinary use. The Language Center at UFRPE is active in preparing PPGBA students.

In 2019, professors Leucio Alves and Rafael Ramos undertook a work mission to the University of Georgia. The mission aimed to establish cooperation agreements involving teaching, research, and extension with the Department of Infectious and Parasitic Diseases at the College of Veterinary Medicine of the University of Georgia. In this context, we approved the visit of Prof. Ray Kaplan, who taught the Special Topics course in November 2019, focusing on anti-helminthic resistance and diagnosis of this parasitosis to PPGBA students. The course included participation from program students and was offered in English. At the end, students presented a seminar in English that facilitated interaction among students, faculty, and Prof. Kaplan. This researcher also met with the CAPES-PrInt Committee of the Program, where matters regarding cooperation between UFRPE and the University of Georgia were discussed. Subsequently, he held a meeting with the Program Board to discuss the strengths of cooperation between PPGBA and the University of Georgia. At another time, still under CAPES-PrInt, Professors Leucio Alves and Rafael Ramos made a technical visit to the University of Georgia in October 2019 to establish an agreement to promote cooperation in teaching, research, and extension with the Department of Infectious Diseases at the College of Veterinary Medicine of the University of Georgia. At the end of the mission, a proposal for a letter of intent was established to conduct exchange activities between UGA and PPGBA in the areas of sandwich doctorate, post-doctorates, and PVE, in addition to discussing the joint doctorate regime between both universities.
