A 5-year-old boy with no past medical history presented to the emergency department with a 4-day history of low-grade fever, abdominal pain, and watery diarrhea with intermittent mild hematochezia. Seven days before presentation, he had attended a family barbecue and had consumed chicken that was slightly raw. His family members showed no symptoms despite consuming the same chicken. On physical examination, he was afebrile, and mild diffuse abdominal pain was noted on deep palpation, whereas the remainder of his physical examination was unremarkable. Gramnegative spiral rods were noted on Gram stain of his stool (Fig. 1), suggesting Campylobacter species. The culture from his stool grew
Campylobacter jejuni on Skirrow’s agar (Fig. 2). His symptoms improved with 3-day course of oral azithromycin. Campylobacter is a Gram-negative spiral rod and one of the most frequent organisms causing food-borne infections, similar to that noted in this case. Our findings suggest that Gram staining of stool specimens may be helpful for the differential diagnosis of Campylobacter enterocolitis. While most patients recover with no antibiotics, oral antibiotics may be administered to young children or those with severe symptoms such as abdominal pain or hematochezia.
