IFNG and Granuloma: It would be of great interest to carry out subsequent studies in order to increase the sample size and quantify the expression of cytokines such as interferon-gamma (IFN-γ), iNOS or IL-17A in each type of granuloma in order to study the immune responses that accompany the progression of the infection, however, this was not possible in this study because of the excessive fixation time in the processing of the samples.
