Abstract

fetched live from OpenAlex

Laboratory contaminants may be introduced at any point between sample collection and analysis. During schistosomiasis control efforts in Côte d’Ivoire, a mite contaminating a urine specimen was visualized under light microscopy that resembled the egg of Schistosoma haematobium. Schistosomiasis and soil-transmitted helminth infections (STH) continue to disproportionately impact children in rural low-income regions. Chronic infection with schistosomiasis results in morbidity related to gastrointestinal disease such as complications of portal hypertension (Schistosoma mansoni) or urogenital disease such as bladder cancer or infertility (S. haematobium).1 Preventative chemotherapy in high-burden settings with praziquantel is recommended by the World Health Organization to mitigate morbidity.2 In this study, urine and stool samples from school-aged children in several villages near Azaguié, Côte d’Ivoire, were analysed as part of ongoing schistosomiasis and STH surveillance projects in the region. Urine was filtered through 20-μm filter paper and visualized under light microscopy for S. haematobium infection. A mite from the Tarsonemidae family is visualized in Figure 1 (black arrow) next to S. haematobium eggs (red arrows). Tarsonemidae mites typically feed on vegetation and are infrequent contaminants of urine and stool specimens.3 These mites share a similar shape, size and colour as schistosome eggs (~120–150-μm long), and could be mistaken for an egg at low power magnification or with rapid review of a slide. Contaminants may be introduced during sample collection, transportation, processing or analysis, and can mimic pathogens; in this case mimicking an egg, in other cases a worm,4,5 Careful examination of slides by expert microscopists can help distinguish contaminants from true pathogens. A mite from the Tarsonemidae family (black arrow) is visualized with Schistosoma haematobium eggs (red arrows) under light microscopy JTC has no conflicts to declare.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
