We evaluated Trypanosoma cruzi infection rates by means of minicircle DNA-based polymerase chain reactions (PCRs) in 70 starved Mepraia gajardoi from northern Chile and 65 M. spinolai from central Chile after feeding. Immediately after collection in the field, 20% of M. gajardoi were found infected; after feeding, 67% of the uninfected were infected. One group of M. spinolai seemed to be completely uninfected, but after the first and second feedings, 62% and 59% were positive, respectively.

Background: Trypanosoma cruzi is a protozoan parasite which causes Chagas disease. Mother-to-child transmission is the main route of transmission in vector-free areas. Congenital Chagas disease refers specifically to cases arising from this route of transmission.

Despite being the most relevant and critical option for managing Chagas disease, pharmacological therapy is currently limited by the availability of only two drugs, benznidazole and nifurtimox. Their effectiveness is further restricted in the chronic phase of the infection, as they induce severe side effects and require prolonged treatment. Additionally, the use of these drugs can lead to the emergence of substantial resistance problems, compounded by the potential natural resistance of some parasite isolates.

Chagas disease is a neglected tropical disease caused by Trypanosoma cruzi with clinical presentations ranging from asymptomatic to cardiac and/or gastrointestinal complications. The mechanisms of pathogenesis are still poorly understood, but T. cruzi strain diversity may be associated with disease progression.

Infectious disease treatment success requires symptom resolution (clinical treatment success), which often but not always involves pathogen clearance. Both of these treatment goals face disease-specific and general challenges. In this review, we summarize the current state of knowledge in mechanisms of clinical and parasitological treatment failure in the context of Chagas disease, a neglected tropical disease causing cardiac and gastrointestinal symptoms.

(1) Background: Chagas disease is a public health problem affecting nearly 2 million women of reproductive age in Latin America. From these, 4-8% can transmit the infection to the foetus through the vertical route, whereas horizontal transmission through milk during breastfeeding remains controversial. Therefore, the presence of () DNA in the milk of women seropositive for Chagas disease was analysed to determine whether a relationship with the infection of their children can exist.
