[Method of multilocus enzyme electrophoresis for typing Neisseria meningitidis serogroup A in China and it's significance in epidemiology].
A new, more perfect taxonomic method the multilocus enzyme electrophoresis has recently been developed to type Neisseria meningitidise serogroup A strains in China isolated from 1956-1987 and to study the epidemiological relationship of the types. 183 strains could be divided into 24 ET types, among which ETs, ET18 were found predominant in epidemics occurred in last two decades respectively. Different predominant ET types were found in different epidemic period and only one predominant ET type existed in each period. The cases and carriers occurred in the interepidemic stage and in some places. Their strains belonged to some endemic ET types.
