We compared the effects of two treatments, antibiotics and FMT, on the levels of inflammatory factors, including the proinflammatory factors TNF-ɑ, IFN-γ, IL-1b, and IL-6, and the anti-inflammatory factor IL-10, in the serum and alveolar lavage fluid of pneumonia-induced sepsis model mice (Figures 4A, B). Here, IFNG is linked to susceptibility to pneumonia measurement.
