[Abstract]:Objective to establish a mouse model of acute bacterial rhinosinusitis. Methods 179 BALB/c mice were randomly divided into 4 groups. Group A and group B BALB/c mice were inserted into the right nasal cavity. Group A was infiltrated with methicillin-resistant Staphylococcus aureus (MRSA) COL suspension and group B was infiltrated with aseptic saline. Group C was only infused with MRSA COL bacteria suspension in the nasal cavity of mice. Group D was used as the control group. The animals were executed at 1, 4, 7 and 14 days respectively. The bacterial culture and pathological section of nasal tissue were studied. Three dead mice (group A) were not included in the data statistics. Results Acute bacterial rhinosinusitis was induced in all mice in group A, and inflammation in nasal cavity was induced in group B. There was significant difference in the degree of inflammation between group A and group B. there was no inflammatory reaction in group C and D. Conclusion: the mouse model of acute bacterial rhinosinusitis was successfully established.
