case_images: She presented with green watery stools devoid of mucus or pus (Figure 1a) and experienced moderate stool volumes exceeding 10 times a day. Gram staining of fecal smear showed gram-positive slender bacilli with non-uniform color (Figure 1b). The acid-fast staining results for the fecal smears were negative, while weak acid-fast staining yielded positive results (Figure 1c). After this incubation period, there was no bacterial growth on MacConkey and SS plates; however, small, dry, non-hemolytic colonies were detected on Columbia blood plates (Figure 1d).
