Estudios de nuevas zonas endémicas de bartonellosis humana o enfermedad de Carrión en el Perú

Abstract

Since 1980 we srudied bartonellosis o Oroya Fever at “The Alexander von Humboldt Institute”,and after 1996 we had detected three patients with Carrion's Disease who just came for three different and new areas: Quillabamba (Cusco), Pasamayo- Boza (Huaral) and a report from a patient from Grocio Prado-Ica. So we decide to evaluate and determinate the seroprevalence of possible cases of Carrion's Disease in Chinche (Quillabamba); because we had two attended patients who had been hospitalized for Carrion's Disease.

We studied four cases with bartonellosis; and since September 27th to October 11 th, we went to Cusco.

Three hundred persons had been evaluated in Chinche (Maranura). At the first one we reported 4 cases of bartonellosis or Oroya fever. At Chinche, we didn't find history of previous bartenellosis in these people. One patient who had diagnosis of Carrion's Disease was found in the community 38 smears and cultures for Bartonella baciliformis were negative.

From two hundred insects collected, we found eight antrophofilic females lutzomyas. A unique, the discase just spread to another areas because of new distribution of lutzomias in new areas (jungle and coast). Fourtuneately we didn't find Bartonella in Quillabamba but there's Lutzomyas from verrucarum's team.
