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

Parasites & 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

Developments in Diagnosis of Visceral Leishmaniasis in the Elimination Era

Journal 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 ...

Experimental Vaccines against Chagas Disease: A Journey through History

Journal 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.

A case–control study on risk factors for visceral leishmaniasis in West Pokot County, Kenya

Tropical Medicine &International Health, Volume 29, Issue 10, Page 904-912, October 2024.
Abstract Background Visceral leishmaniasis (VL) is a severe parasitic disease transmitted by phlebotomine sandflies. VL is endemic in West Pokot County, Kenya, where effective strategies to interrupt transmission are impeded by the limited understanding of VL risk factors.

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

BioMed 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 ...

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

Journal 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.

Infecção experimental de Lutzomyia whitmani em cães infectados com Leishmania braziliensis braziliensis Experimental infection of Lutzomya whitmani in dogs infected with Leishmania braziliensis brasiliensis

Memorias do Instituto Oswaldo Cruz, 1986
Lutzomyia (N.) whitmani foi infectada em lesões leishmanióticas de três de nove cães parasitados por Leishmania braziliensis braziliensis . Os índices de infecção desses flebotomíneos foram 8,3% (1/12), 7,1% (1/14) e 1,8% (3,160), respectivamente.

Combining epidemiology with basic biology of sand flies, parasites, and hosts to inform leishmaniasis transmission dynamics and control. [PDF]

, 2017
Quantitation of the nonlinear heterogeneities in Leishmania parasites, sand fly vectors, and mammalian host relationships provides insights to better understand leishmanial transmission epidemiology towards improving its control. The parasite manipulates

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

Journal 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
