Dissemination of N. meningitidis in BALB/c-flu infected mice. Sequential IAV (250 PFU per mouse) and meningococcal infection (107 CFU per mouse) were performed by the intranasal route. Bacterial infection was analysed by bioluminescence at the indicated times. Images depict photographs overlaid with colour representations of luminescence intensity, measured in total photons/s and indicated on the scales, in which red is the most intense and blue the least intense. a Ventral views of nine PBS-fed and 10 L. paracasei-fed mice. A non-infected mouse was added as a control. b. The luminescence was quantified and expressed as the means ± SEM for each category at the indicated times by defining specific representative regions of interest encompassing the entire animal
