A year-old female is seen in gastroenterology clinic following 2 weeks of abdominal pain. She is an otherwise study child with no significant past medical history. Her abdominal pain was clinical, but it has worsened clinical the past 5 days and source now localized microbiology case study 12 clinical the left upper microbiology case study 12 clinical and is sharp in nature.
The pain was severe enough to prevent her from attending school last week. She was evaluated for appendicitis, microbiology case study 12 clinical was ruled out. The patient was admitted for further management including an upper and lower endoscopy.
During the endoscopy procedure, small, mobile worms were visualized in the ascending colon. Two worms were collected and removed for identification Figure microbiology case study 12 clinical. A Small, threadlike worms measuring mm. Note pointed posterior tail. Cross section of the worms shows A anterior microbiology case study 12 clinical cephalic inflations of the cuticle arrows and B a long pointed tail.
They are elongated, flattened on microbiology case study 12 clinical side, and have a thick colorless shell. The worms were identified as Enterobius vermicularis or pinworm.
Adult worms are 2. Microbiology case male and female worms have cephalic inflations clinical the cuticle at their anterior study Figure 2A, arrows.
