Xenodiagnosis to address key questions in visceral leishmaniasis control and elimination.

PLoS Neglected Tropical Diseases, 2020
Visceral leishmaniasis (VL) remains an important public health issue worldwide causing substantial morbidity and mortality. The Indian subcontinent accounted for up to 90% of the global VL burden in the past but made significant progress during recent ...

Parasite persistence in treated chagasic patients revealed by xenodiagnosis and polymerase chain reaction [PDF]

Memorias do Instituto Oswaldo Cruz, 2001
Polymerase chain reaction (PCR) was compared with xenodiagnosis performed 20 years after trypanocidal chemotherapy to investigate parasite clearance. Eighty-five seropositive individuals for Chagas disease presenting a positive xenodiagnosis were treated

Trypanosoma cruzi parasitemia observed in immunocompromised patients: the importance of the artificial xenodiagnosis [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 2001
Trypanosoma cruzi parasitemia observed in immunocompromised patients (transplant or positive HIV) occurred more frequently by the artificial xenodiagnosis method (10/38) compared with hemoculture (2/38), given the same quantity of blood.

Heterogeneities in leishmania infantum infection : using skin parasite burdens to identify highly infectious dogs [PDF]

, 2013
Background: The relationships between heterogeneities in host infection and infectiousness (transmission to arthropod vectors) can provide important insights for disease management.

Observation about the experimental xenodiagnosis in American Trypanosomiasis

Revista Peruana de Biología, 2014
Seven third stage nymphs of Triatoma infestans were infected with Trypanosoma cruzi of mice during the acute phase. After a time of being positives, the triatomids became a microscopical negative in feces examination.

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.

Evaluation of the Diagnostic Sensitivity of the VIASURE Leishmania Real‐Time PCR Detection Kit Prototype for the Diagnosis of Cutaneous and Visceral Leishmaniasis

Transboundary and Emerging Diseases, Volume 2023, Issue 1, 2023., 2023
Leishmaniasis is a parasitic disease with clinical presentations that vary from asymptomatic infection to cutaneous, mucocutaneous, or visceral disease. Global change, with migratory movements and travels, among others, has had an impact on the presentation of the clinical forms of leishmaniasis in a given area, hindering its diagnosis. The traditional

Evaluating the Clinical and Immune Responses to Spotted Fever Rickettsioses in the Guinea Pig‐Tick‐Rickettsia System

Current Protocols, Volume 2, Issue 11, November 2022., 2022
Abstract The guinea pig was the original animal model developed for investigating spotted fever rickettsiosis (SFR). This model system has persisted on account of the guinea pig's conduciveness to tick transmission of SFR agents and ability to recapitulate SFR in humans through clinical signs that include fever, unthriftiness, and in some cases the ...

Laboratory evidence that dinotefuran, pyriproxyfen and permethrin combination abrogates Leishmania infantum transmissibility by sick dogs

Medical and Veterinary Entomology, Volume 36, Issue 1, Page 81-87, March 2022., 2022
The effect of dinotefuran, pyriproxyfen and permethrin spot‐on solution (Vectra®3D) on Leishmania infantum transmissibility by naturally sick dogs via reared Phlebotomus perniciosus, was assessed. Six dogs submitted to xenodiagnosis and infecting >10% of sand fly females were treated on day 0; anti‐transmissibility effects were evaluated again by ...
