The Seroprevalence of Equine Trypanosomosis in the Pantanal [PDF]

Memórias do Instituto Oswaldo Cruz, 1999
Since little information is available on the epizootiological status of Trypanosoma evansi in South America and particularly Brazil, we evaluated equine serum samples collected in 1993, 1994, 1995 and 1997 for the presence of antibodies against this trypanosome species. Our study shows corroborative evidence about the correlation among high T.

High false discovery rate of the Architect anti‐HCV screening test in blood donors in Uganda and evaluation of an algorithm for confirmatory testing

Vox Sanguinis, Volume 117, Issue 12, Page 1360-1367, December 2022., 2022
Abstract Background and Objectives Adequate supplies of donor blood remain a major challenge in sub‐Saharan Africa. This is exacerbated by a lack of confirmatory testing for transfusion‐transmitted infections by blood transfusion services (BTS), leading to significant blood disposal owing to putatively high seroprevalence rates amongst Ugandan blood ...
