A crude extract of Escherichia coli O13:K92:H4 inhibited 97% of positive indirect immunofluorescence titers against a variety of gram-negative bacterial antigens while lowering Legionella pneumophila titers in only 6% of sera from patients with suspected legionellosis. Legionella-specific titers were the result of immunoglobulins G, M, and A, singly or in combination.
