A modification of Koga agar plate culture was performed, consisting of a 2 × 2‐cm cellophane paper centered on the agar plate to prevent bacterial contamination of the agar and daily dish examinations (days 2–5). Between January 2000 and July 2005, we examined 1,708 infection‐suspected patients, of which 147 (8.6%) harbored . Single modified agar plate cultures exhibited superior sensitivity (93.2%), compared with different three‐sample screening methods (sensitivity—Baermann: 76.6%, formalin‐ethyl acetate: 22%, and direct smear: 15.3%). Agar plate cultures stand out as helpful alternatives for improved detection and therapy monitoring in poor countries and endemic areas. Combined with Baermann methods, they provide increased probability for detection.
