Open AccessImmunoglobulin and T cell receptor repertoire changes induced by a prototype vaccine against Chagas disease in naïve rhesus macaques
A vaccine against Trypanosoma cruzi, the agent of Chagas disease, would be an excellent additional tool for disease control. A recombinant vaccine based on Tc24 and TSA1 parasite antigens was found to be safe and...

Molecular Characterization of Four Mexican Isolates of Trypanosoma cruzi and Their Profile Susceptibility to Nifurtimox
The objective of this study was to molecularly characterize Mexican isolates of T. cruzi obtained from infected triatomine bugs (the vectors of T. cruzi) and to evaluate their susceptibility to Nifurtimox (NFX).

Active Transmission of Trypanosoma cruzi in Schoolchildren from the Amazon Region in Napo Province, Ecuador
Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, is a vector-borne disease with a major disease burden in the Americas, with over 6 million cases. There are about 200,000 cases in Ecuador, but ...

Seroprevalence of Trypanosoma cruzi Infection in Pregnant Women Suggests a High Risk for Congenital Transmission in Central Veracruz, Mexico
The state of Veracruz, Mexico, is a well-recognized endemic region for Chagas disease, but congenital transmission has not been extensively studied. We estimated here the prevalence and the risk of congenital ...

Open AccessDisentangling Trypanosoma cruzi transmission cycle dynamics through the identification of blood meal sources of natural populations of Triatoma dimidiata in Yucatán, Mexico
In the Yucatán Peninsula, Mexico, Triatoma dimidiata is the main vector of Trypanosoma cruzi, the causative agent of Chagas disease. Little effort has been made to identify blood meal sources of T. dimidiata in n...

Open AccessHigh prevalence of Trypanosoma cruzi infection in shelter dogs from southern Louisiana, USA
Chagas disease is a zoonotic disease caused by the protozoan parasite Trypanosoma cruzi. The role of dogs as sentinels has been proposed in multiple regions, as they are a domestic reservoir for T. cruzi. Our obj...

Mining Trypanosoma cruzi Genome Sequences for Antigen Discovery and Vaccine Development
A large number of studies have demonstrated that Trypanosoma cruzi can be controlled by vaccines in animal models, but the identification of effective vaccine antigens represents one of the most critical steps in...

An Improved Approach to Trypanosoma cruzi Molecular Genoty** by Next-Generation Sequencing of the Mini-exon Gene
Trypanosoma cruzi, the etiological agent of Chagas disease, is a protozoan parasite usually transmitted by triatomines. As the parasite can infect all mammals and the vectors can be found across a broad range of ...

Open AccessSlee** habits affect access to host by Chagas disease vector Triatoma dimidiata
Chagas disease, caused by the parasite Trypanosoma cruzi, is mainly transmitted by blood-sucking bugs called triatomines. In the Yucatán Peninsula, Mexico, the main vector of T. cruzi is Triatoma dimidiata. While...

Open AccessNegative studies are helpful to compute the specificity of diagnostic tests: measuring Trypanosoma cruzi seroprevalence in Guanajuato, Mexico
Publishing negative seroprevalence studies not only helps to have more accurate seroprevalence estimates but also allows calculating the specificity of the diagnostic tests used. We performed a population-based T...

Open AccessHighly discordant serology against Trypanosoma cruzi in central Veracruz, Mexico: role of the antigen used for diagnostic
Chagas disease is a parasitic disease caused by the protozoan parasite Trypanosoma cruzi. In Mexico, the burden of the disease is difficult to estimate and improving surveillance for Chagas disease is an importan...

Open AccessA canine model of experimental infection with Leishmania (L.) mexicana
Cutaneous leishmaniasis is a tropical disease affecting over one million patients annually and Leishmania (L.) mexicana is one of the major etiological agents in the Americas. Here we established the first experi...

Innovation for the ‘Bottom 100 Million’: Eliminating Neglected Tropical Diseases in the Americas
An estimated 100 million people in the Latin American and Caribbean (LAC) region live on less than US$2 per day, while another 46 million people in the US live below that nation’s poverty line. Almost all of t...
