摘要：

A negatively stained electron micrograph of regularly arranged porin proteins of Campylobacter jejuni on the isolated outer membrane of bacteria was analyzed in detail by the correlation averaging method using a computer-assisted program, The results showed that the porin of C, jejuni had a trimeric structure separated by about 10.4+/-0.15 nm, In addition, the pores in the trimers were also separated by about 4.3+/-0.1 nm.
