Developments in Diagnosis of Visceral Leishmaniasis in the Elimination Era

open access: yesJournal of Parasitology Research, Volume 2015, Issue 1, 2015., 2015
Visceral leishmaniasis (VL) is the most devastating parasitic infection worldwide causing high morbidity and mortality. Clinical presentation of VL ranges from asymptomatic or subclinical infection to severe and complicated symptomatic disease. A major challenge in the clinical management of VL is the weakness of health systems in disease endemic ...

Within-host temporal fluctuations of Trypanosoma cruzi discrete typing units: the case of the wild reservoir rodent Octodon degus

open access: yesParasites & Vectors, 2017
Background Chagas disease caused by Trypanosoma cruzi is considered a major public health problem in America. After an acute phase the disease changes to a chronic phase with very low parasitemia. The parasite presents high genetic variability with seven

Experimental Vaccines against Chagas Disease: A Journey through History

open access: yesJournal of Immunology Research, Volume 2015, Issue 1, 2015., 2015
Chagas disease, or American trypanosomiasis, which is caused by the protozoan parasite Trypanosoma cruzi, is primarily a vector disease endemic in 21 Latin American countries, including Mexico. Although many vector control programs have been implemented, T. cruzi has not been eradicated. The development of an anti‐T.

Revisiting the Posttherapeutic Cure Criterion in Chagas Disease: Time for New Methods, More Questions, Doubts, and Polemics or Time to Change Old Concepts?

open access: yesBioMed Research International, Volume 2015, Issue 1, 2015., 2015
One of the most relevant issues beyond the effectiveness of etiological treatment of Chagas disease is the lack of consensual/feasible tools to identify and certify the definitive parasitological cure. Several methods of distinct natures (parasitological, serological, and molecular) have been continuously proposed and novel perspectives are currently ...

Physiological Age Structure and Leishmania spp. Detection in Phlebotomus (Larroussius) orientalis (Parrot, 1936) (Diptera: Psychodidae) at an Endemic Focus of Visceral Leishmaniasis in Northern Ethiopia

open access: yesJournal of Tropical Medicine, Volume 2015, Issue 1, 2015., 2015
Visceral leishmaniasis (VL) caused by Leishmania donovani is endemic in northern Ethiopia, where P. orientalis is the most important presumed vector. This study was designed to determine the physiological age structure and the occurrence of Leishmania infection in the vector of VL in Tahtay Adiyabo district, northern Ethiopia. Sand flies were collected

CD8+ T Cell‐Mediated Immunity during Trypanosoma cruzi Infection: A Path for Vaccine Development?

open access: yesMediators of Inflammation, Volume 2014, Issue 1, 2014., 2014
MHC‐restricted CD8+ T cells are important during infection with the intracellular protozoan parasite Trypanosoma cruzi, the causative agent of Chagas disease. Experimental studies performed in the past 25 years have elucidated a number of features related to the immune response mediated by these T cells, which are important for establishing the ...

Xenodiagnosis: use of mosquitoes for the diagnosis of arboviral infections [PDF]

open access: yesJournal of Vector Borne Diseases, 2007
The arboviruses have a worldwide distribution and, mosquitoes and ticks contribute principally intheir transmission. In the last two decades, arboviral diseases have been recognised due to theirresurgence and spread in newer geographic areas.
