Intravenous infection of C57BL/6 and C57BL/10 mice with low doses of a highly virulent strain of Mycobacterium avium (ATCC 25291) led to the development of granulomas that underwent necrosis. In contrast, neither BALB/c nor DBA/1 mice developed granuloma necrosis after such infection despite a similar course of mycobacterial proliferation. Studies with C57BL/10 mice congenic for the Hc locus revealed that an intact complement C5 gene is required for granuloma necrosis. On the other hand, genetic disruption of the interleukin-10 gene in BALB/c mice made this strain susceptible to granuloma necrosis.
用低剂量高毒力鸟分枝杆菌菌株(ATCC 25291)对C57BL/6和C57BL/10小鼠进行静脉感染,会导致肉芽肿形成并发生坏死。相比之下,BALB/c和DBA/1小鼠在这种感染后虽有相似的分枝杆菌增殖过程,但均未发生肉芽肿坏死。对Hc位点同基因的C57BL/10小鼠的研究表明,肉芽肿坏死需要完整的补体C5基因。另一方面,BALB/c小鼠白细胞介素-10基因的基因破坏使该品系易发生肉芽肿坏死。
