(A) Gelada with a cyst characteristic of confirmed larval T. serialis infections protruding from the abdomen. (B) Internal view of coenuri in the cyst of an infected individual necropsied upon natural death.
Fig 2.
Receiver operator characteristic (ROC) curve of antigen ELISA detection of T. serialis infection in dried gelada urine.
The optimal threshold cutoff index value (42.1) had an estimated specificity of 98.4% (95% CI: 95.1–1) and an estimated sensitivity of 98.5% (95% CI: 95.6–1).

Fig 3.
Counts of log sample index values (IVs) (the optical density of each sample indexed to the positive and negative controls on each plate) + a constant.
Blue bars indicate samples from individuals without cysts, while grey bars indicate samples from individuals with cysts. The dotted line indicates the optimal threshold cutoff for positive samples indicating antigen presence calculated with the ROC analysis.
