The high titres of circulating agglutinin associated with immunity were shown to be due to the interaction between antibodies and pili. These observations are discussed in relation to the structure and pathogenicity of other Gram-negative organisms. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-77-2-351
