ABSTRACT

Objetivo: La lipoproteína de 43-kDa de Bartonella bacilliformis fue obtenida en su forma recombinante (rBbLppB) ypurificada para evaluar su serorreactividad mediante ELISA. Materiales y métodos: Los niveles de anticuerpos IgG eIgM humanos en los sueros de pacientes con Bartonelosis confirmada y sueros de otras enfermedades (salmonelosis,Brucelosis y leptospirosis) frente a rBbLppB fueron evaluados por ELISA, se utilizó sueros de personas sanas comocontroles. Resultados: La sensibilidad y la especificidad del ELISA IgG fueron 70,4 y 90 respectivamente. Asimismo,la sensibilidad y especificidad de ELISA IgM fueron 85,2 y 90 respectivamente. Conclusiones: Estos resultadosdemuestran que el ELISA usando rBbLppB tiene una buena sensibilidad y especificidad y puede ser consideradacomo un buen antígeno para el diagnóstico de Bartonelosis causada por B. bacilliformis.


Objective: The Bartonella bacilliformis 43-kDa lipoprotein was obtained from its recombinant form (rBbLppB) and then, purified to evaluate sero-reactivity through ELISA. Material and methods: IgG and IgM humanantibodies levels in the sera of patients with confirmed Bartonellosis and sera of patients with other diseases (salmonellosis, Brucellosis and Leptospirosis), when contrasted with rBbLppB were evaluated by ELISA. Sera from some healthy people were used for controls. Results: Sensitivity and specificity of the IgG ELISA were 70,4% and 90% respectively. Also, sensitivity and specificity of the IgM ELISA were 85,2% and 90%, respectively. Conclusions: These results show that ELISA using rBbLppB is highly sensitive and specific and may be considered a good antigen for the diagnosis of Bartonellosis caused by B. bacilliformis.
