Early detection of novel Leishmania species DNA in the saliva of two HIV-infected patients.

The prevalence of Leishmania infection in HIV infected patients within this study is 0.95%. Leishmania DNA was detected in saliva by PCR prior to blood and buffy coat of two HIV infected patients. Early detection of Leishmania DNA in saliva would be beneficial for the follow up of asymptomatic Leishmania infected patients, the early treatment of leishmaniasis and for surveillance survey purpose. However, full evaluation of sensitivity and specificity of this technique with a large cohort of patients is required before deployment.
