ABSTRACT We evaluated a commercially available immunochromatographic dipstick test to detect Trypanosoma cruzi infection in 366 human serum samples with known serological results from Argentina, Ecuador, Mexico, and Venezuela. One hundred forty-nine of 366 (40.7%) and 171/366 (46.7%) samples tested positive by dipstick and serology, respectively. Dipstick sensitivity was calculated to be 84.8% (range between countries, 77.5 to 95%), and specificity was 97.9% (95.9 to 100%).

    ABSTRACT: A 2.25-y-old male pigtailed macaque (Macaca nemestrina) was experimentally irradiated and received a bone marrow transplant. After transplantation and engraftment, the macaque had unexpected recurring pancytopenia and dependent edema of the prepuce, scrotum, and legs. The diagnostic work-up included a blood smear, which revealed a trypomastigote consistent with Trypanosoma cruzi, the causative agent of Chagas disease (CD). We initially hypothesized that the macaque had acquired the infection when it lived in Georgia. However, because the animal had received multiple blood transfusions, all blood donors were screened for CD. One male pigtailed macaque blood donor, which was previously housed in Louisiana, was positive for T. cruzi antibodies via serology. Due to the low prevalence of infection in Georgia, the blood transfusion was hypothesized to be the source of T. cruzi infection. The transfusion was confirmed as the mechanism of transmission when screening of archived serum revealed seroconversion after blood transfusion from the seropositive blood donor. The macaque made a full clinical recovery, and further follow-up including thoracic radiography, echocardiography, and gross necropsy did not show any abnormalities associated with CD. Other animals that received blood transfusions from the positive blood donor were tested, and one additional pigtailed macaque on the same research protocol was positive for T. cruzi. Although CD has been reported to occur in many nonhuman primate species, especially pigtailed macaques, the transmission of CD via blood transfusion in nonhuman primates has not been reported previously.

    ABSTRACT: Background:Chagas disease is one of the main public health issues in Latin America. Increasingly, during the past few decades, the T. cruzi infection has been detected in North America, Europe and the Western Pacific, mainly as a result of population movements.. The limited availability of rapid serological diagnostic tests hinders its improved detection and widespread treatment in endemic and non-endemic areas.Method:In collaboration with 11 national reference laboratories (NRL) from different geographical areas, we evaluated the performance of commercialized rapid serological diagnostic tests (RDT) for T. cruzi infection. Eleven commercialized T. cruzi infection RDTs were evaluated on a total of 474 samples extensively tested with at least three different techniques for Chagas disease and maintained at controlled low temperatures and stored in the serum banks of the 11 NRLs. We measured the sensitivity, specificity and concordance of each RDT and provided an additional questionnaire to evaluate their usability. The tests of the selected RDTs in this study were done under controlled laboratory conditions.Results:Out of the 11 RDTs, we found 8 of them were useful; the cassette format was favored over the strip. We did not observe significant differences in RDT performance in the different regions. Overall, performance results were lower than those disclosed by the manufacturers.Conclusion:The results of this evaluation validate the possibility of using RDTs to diagnose Chagas disease thereby in decreasing time to treatment at primary health care level for patients who are willing to be treated. Further comparable studies should be conducted in the laboratory and on the field to confirm this data, expressly to evaluate reproducibility in resource-limited settings, or in clinical settings using whole blood in endemic and non-endemic areas.

    ABSTRACT: Rapid, sensitive detection methods are of utmost importance for the identification of pathogens related to health and safety. Herein we report the development of a nucleic acid sequence-based lateral flow assay which achieves a low limit of detection using chemiluminescence. On-membrane enzymatic signal amplification is used to reduce the limit of detection to the sub-femtomol level. To demonstrate this assay, we detected synthetic nucleic acid sequences representative of Trypanosoma mRNA, the causative agent for African sleeping sickness, with relevance in human and animal health in sub-Saharan Africa. The intensity of the chemiluminescent signal was evaluated by using a charge-coupled device as well as a microtiter plate reader. We demonstrated that our lateral flow chemiluminescent assay has a very low limit of detection and is easy to use. The limit of detection was determined to be 0.5 fmols of nucleic acid target.
