IL6 and brucellosis: Considering that the main consequences of B. canis infection are osteoarticular lesions such as diskospondylitis and the presence of granulomatous lesions in affected organs [1, 60, 61], it is possible to assume that the presence of IL-6 and IL-17 could lead to a Th17-pattern of immune response, contributing to the brucellosis pathogenicity in infected dogs.
