In the Americas, Brazil is responsible by 90% of the cases registered of visceral leishmaniasis (VL), and Leishmania infantum is the most common parasite species responsible by disease in Brazilian dogs and humans. A precise diagnosis may allow to a faster and more effective treatment against the disease, which increases the possibility of cure, as well as to induce less toxic effects, due to a lower time exposition for the chemotherapeutics. In a previous study, two L. infantum mimotopes, B10 and C01 clones, were recognized by antibodies in VL dogs sera by a phage display technology, and were well-successfully evaluated as vaccine candidates against visceral and tegumentary leishmaniasis...

In the present study, a conserved Leishmania hypothetical protein, namely LiHypA, was evaluated for the serodiagnosis of visceral and tegumentary leishmaniasis in dogs and humans. This protein showed a high amino acid sequence homology between viscerotropic and cutaneotropic Leishmania species. An enzyme-linked immunosorbent assay (ELISA) was developed using the recombinant antigen (rLiHypA), in addition to the A2 protein and two parasite antigenic preparations, which were used as controls. Regarding human diagnosis, results showed that rLiHypA was more sensitive and specific than ELISA-L...

The delayed appearance of a papule after returning from travelling hints towards the diagnosis cutaneous leishmaniasis. Histologically, a granulomatous inflammatory response is seen, and using Giemsa staining, intracellular parasites can be visualized within histiocytes. Polymer chain reaction (PCR) from the tissue or subsequent cultures not only aids in excluding other differential diagnoses, but also in the identification of the causing Leishmania subspecies. The latter is important for the choice of the optimal therapeutic regimen...

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 cytology of cervical and axillary lymph nodes yielded a diagnosis of leishmaniasis. Diagnosis of VL was challenging as the disease closely mimicked tuberculosis in the setting of extensive lymphadenopathy including conglomerate of mesenteric lymph nodes, on and off fever, and granulomatous lymphadenitis on aspiration...

Three Leishmania species are responsible of cutaneous leishmaniasis (CL) in Morocco. Zoonotic CL due to Leishmania major and Leishmania infantum, the first is known as established in the eastern arid regions, whereas the latter evolves sporadically, especially in the North. While Leishmania tropica, classically considered anthroponotic, is endemic in the semi-arid regions and is largely distributed throughout the country. The aim of this study was to identify the Leishmania species causing CL in two Provinces in arid pre-Saharan region known as zoonotic CL foci, and to contribute an update to the national data concerning the distribution of Leishmania species in both regions...

BACKGROUND: Visceral leishmaniasis (VL) affecting HIV-infected patients is considered a challenging condition because of its high mortality and relapse rates. The approach of this condition is still surrounded by many uncertainties, especially regarding the criteria to institute and discontinue secondary prophylaxis for VL. The aim of this study was to evaluate the Leishmania parasitism kinetic assessed by polymerase chain reaction (PCR) as a possible tool in the prognostic assessment in a context in which patients are receiving highly active antiretroviral therapy and secondary prophylaxis...

Visceral leishmaniasis (VL) is a chronic infectious disease endemic in tropical and sub-tropical areas including the Mediterranean basin, caused by a group of protozoan parasites of the genus Leishmania and transmitted by phlebotomine sandflies. Immunocompromised patients, in particular HIV positive, are considered at risk of VL. They report atypical signs and poor response to treatment due to impairment of T-helper and regulatory cells activity. Laboratory diagnosis is based on microscopy on bone marrow or spleen aspirates...

In South America, visceral leishmaniasis is frequently caused by Leishmania infantum and, at an unknown frequency, by Leishmania amazonensis. Therefore, mixed infections with these organisms are possible. Mixed infections might affect the clinical course, immune response, diagnosis, treatment and epidemiology of the disease. Here we describe the clinical course of mixed infections with L. amazonensis and L. infantum in a hamster model. We show that mixed infections are associated with more severe clinical disease than infection with L...

Due to increased migration, Chagas disease has become an international health problem. Reliable diagnosis of chronically infected people is crucial for prevention of non-vectorial transmission as well as treatment. This study compared four distinct PCR methods for detection of Trypanosoma cruzi DNA for the use in well-equipped routine diagnostic laboratories. DNA was extracted of T. cruzi-positive and negative patients' blood samples and cultured T. cruzi, T. rangeli as well as Leishmania spp. One conventional and two real-time PCR methods targeting a repetitive Sat-DNA sequence as well as one conventional PCR method targeting the variable region of the kDNA minicircle were compared for sensitivity, intra- and interassay precision, limit of detection, specificity and cross-reactivity...

Although some studies have investigated the potential role of cats as a reservoir for Leishmania, their role in the epidemiology of visceral leishmaniasis (VL) is still poorly understood. Molecular diagnostic techniques are an important tool in VL diagnosis, and PCR shows high sensitivity and specificity for Leishmania spp. detection. Quantitative real-time PCR (qPCR) is a method that permits quantitative analysis of a large number of samples, resulting in more sensitive, accurate, and reproducible measurements of specific DNA present in the sample...

American tegumentary leishmaniasis (ATL) is considered a neglected disease, for which an effective vaccine or an efficient diagnosis is not yet available and whose chemotherapeutic arsenal is threatened by the emergence of resistance by etiological agents such as Leishmania amazonensis. ATL is endemic in poor countries and has a high incidence in Brazil. Vaccines developed from native parasite fractions have led to the identification of defined antigenic subunits and the development of vaccine adjuvant technology...

Trypanosoma lewisi, transmitted by rat fleas, is a widespread pathogen specific to rats with records of human infection cases. Its closely related species with global distribution, Trypanosoma musculi, is transmitted between mice by ingestion of infected fleas. These trypanosomes are of similar morphology, making it difficult to distinguish them by microscopy. In this study, we have developed a rapid, sensitive and reliable PCR method for the diagnosis of T. lewisi and T. musculi. The T. lewisi-specific amplicons were not produced by other Trypanosoma, such as T...
