Visceral leishmaniasis (VL), also known as kala-azar, is a disseminated protozoan infection caused by Leishmania donovani complex. Traditionally the definite diagnosis is made by amastigote detection in the tissue. The aim this study was to evaluate the PCR technique in stained slides of bone marrow and lymph nodes aspirates with suspect diagnosis for leishmaniasis. Slides were selected totalin...
INTRODUCTION Leishmania braziliensis infection induces a large spectrum of lesions that clinically manifest as nodules or papules that progress to ulcers. Although it is already known that T helper cells predominate in the lesions, cytotoxic T cells have also been reported to be present, and their role in leishmaniasis immunopathogenesis is not well known. This study investigated the amounts of...
Visceral leishmaniasis (VL), also known as kala-azar, is a life-threatening systemic disease caused by the obligate intracellular protozoan, Leishmania, and transmitted to humans by the female phlebotomine sand fly (Phlebotomus argentipes). The disease is fatal, if left untreated. We report a case of a patient clinically suspected of disseminated tuberculosis, but fine needle aspiration cytolog...
This type of molluscoid lesion obliges us to rule out cryptococcosis, histoplasmosis, atypical mycobacteria, molluscum contagiosum, disseminated leishmaniasis, and leprosy.1,2,5,7 We draw attention to the fact that the patient was a young woman of childbearing age who came from an endemic area with favorable environmental conditions for the fungus. She did not present immunosuppression except f...
We present the sequencing and annotation of the Leishmania (Leishmania) amazonensis genome, an etiological agent of human cutaneous leishmaniasis in the Amazon region of Brazil. L. (L.) amazonensis shares features with Leishmania (L.) mexicana but also exhibits unique characteristics regarding geographical distribution and clinical manifestations of cutaneous lesions (e.g. borderline disseminat...
Tegumentary Leishmaniasis (TL) is endemic in Latin America, and Brazil contributes approximately 20 thousand cases per year. The pathogenesis of TL, however, is still not fully understood. Clinical manifestations vary from cutaneous leishmaniasis (CL) to more severe outcomes, such as disseminated leishmaniasis (DL), mucosal leishmaniasis (ML) and diffuse cutaneous leishmaniasis (DCL). Many fact...
