PACRG and infection: Although other authors have interpreted these results to mean that glycolysis may play an important role in metabolism and virulence of intracellular Brucella (Gao et al., 2016), the multiplication of B. abortus in mouse spleens occurs early during infection [when no role for gluP was observed (Hong et al., 2000)] before the numbers of bacteria reach a short plateau after which it decreases progressively (Grilló et al., 2012).
