Background: Stability of intestinal flora is not only important for
maintaining stable immune functions; it is also a key immune channel
communicating the interaction between lung and intestine. In this study,
probiotics and fecal microbiota transplantation (FMT) were used to regulate
influenza-infected mice with antibiotic-induced intestinal dysbiosis and the
effects of intestinal microorganisms on these mice were subsequently observed and
evaluated. Methods: Mice are housed in a normal environment with
intranasal infection with influenza virus (FM1). Real-time quantitative
polymerase chain reaction (RT-qPCR) was used to determine messenger RNA
expression and lung viral replication of toll-like receptor 7 (TLR7), myeloid
differentiation primary reaction 88 (MyD88) and nuclear factor
