[Induction of polyvalent immunity against Actinobacillus pleuropneumoniae in an experimental rat model]. / Inducción de inmunidad polivalente contra Actinobacillus pleuropneumoniae en un modelo experimental en la rata.

Using an experimental model of passive immunity in the rat, the immunizing effect of live cells of Actinobacillus pleuropneumoniae serotypes 1, 3, 5, 7, 9 and 12 was tested against a challenge with serotype 1. It was observed that serotypes 5, 7 and 9 induced polyvalent immunity. Additionally, agglutinating antibodies to the homologous and heterologous serotype were titrated in the sera of immunized mothers; the results indicated that groups immunized with serotypes 5, 7 and 9 had higher titers against serotype 1.

Pleuropulmonary tularemia: successful treatment with erythromycin.

A 64-year-old man had community-acquired pneumonia that was retrospectively diagnosed as pleuropulmonary tularemia. He was successfully treated with erythromycin. We review the case and briefly discuss the literature on this point.
