The bowel flora of guinea-pigs was studied using non-selective cultural conditions and conditions highly selective for Escherichia coli organisma. No E. coli were cultured from adult or juvenile bowel content. Parallel studies showed that culture media supported the growth of small numbers of reference E. coli "seeded" into them along with bowel content. It is concluded that normal adult laboratory guinea-pigs may be bacteriologically equivalent to the NCS strain of "E. coli-free" mice.
利用非选择性培养条件以及对大肠杆菌具有高度选择性的条件,对豚鼠的肠道菌群进行了研究。在成年或幼年豚鼠的肠道内容物中均未培养出大肠杆菌。平行研究表明,培养基能够支持少量与肠道内容物一同“接种”进去的参考大肠杆菌的生长。得出的结论是,正常成年实验豚鼠在细菌学上可能等同于“无大肠杆菌”的NCS品系小鼠。
