case_images: Microbiological Gram staining of CSF revealed only typical Gram-positive cluster forming cocci (Figure 1(a)). We observed that Gram-positive colonies were sticky in nature, whitish/gray, nonhemolytic, smooth, and round after 24 h of incubation at 37 C in CO2 in sheep blood agar (Figures 1(b) and 1(c)).
