A novel animal model for subcutaneous soft tissue infection using temporally neutropenic lys-EGFP mice

Neutrophils play an important role against bacterial infection, mainly methicillin resistant Staphylococcus aureus (MRSA). Therefore, we developed an animal model to simultaneously monitor bacterial colonization and neutrophil migration in vivo. Using lys-EGFP C57BL/6 mice, we initially rendered the...

Therefore, we developed an animal model to simultaneously monitor bacterial colonization and neutrophil migration in vivo. Using lys-EGFP C57BL/6 mice, we initially rendered the mice temporally neutropenic using cyclophosphamide (CPM) treatment (300mg/kg or 375mg/kg). Later, bioluminescent MRSA (Xen31, PerkinElmer) were subcutaneously injected (1.0×107 CFU) into the dorsal skin of the neutropenic lys-EGFP mice.

For the evaluation of MRSA activity and neutrophil accumulation, an in vivo imaging system (LAS-4000, GE) was performed. Our results demonstrated that vancomycin is capable of killing bacterial cells and it also promotes inflammation. In addition, the rate of neutrophil regeneration after being suppressed by CPM is dependent on the dose of CPM. We could conclude that vancomycin is capable of inducing inflammation but the effects of the drug could only be observed if the immune system is adequately suppressed. 2015 Conference or Workshop Item PeerReviewed application/pdf en http://irep.iium.edu.my/44920/1/A_Novel_Animal_Model_for_Subcutaneous_Soft.pdf application/pdf en http://irep.iium.edu.my/44920/4/ascc_proceeeding_cove%2C_copyright%2C_content.pdf Zulaziz, N. and Azhim, Azran and Miyazaki, H. and Kinoshita, M. and Himeno, N. and Saitoh, D. and Morimoto, Y.
