CASE STUDY 2 Renota, a 51-year-old Slavic woman, lived in Romania with her family on a pig farm. She routinely slaughtered pigs and cooked pork for family meals. She had a wide variety of recipes that called for pork. A few days after preparing one of her famous pork dishes, Renota experienced diarrhea, abdominal pain, and chronic indigestion. She went to her family physician and explained her symptoms to him. The physician, who knew the family well and was familiar with the family business, immediately suspected a bacterial or parasitic infection. A stool sample for routine bacterial culture and O&P study was collected from Renota and submitted to the local diagnostic laboratory. Routine processing procedures were conducted on the stool sample. Gross examination of the stool revealed a portion of the infecting worm (Fig. A). An egg, measuring 36 by 25 um (Fig. B), was seen on the permanent O&P slide. No intestinal bacterial pathogens were isolated. 1. What is the morphologic form of Figure A? 2. Label the designated structures in Figures A and B. A1: B2: B3: B4: 3. Which genus of organism do you suspect? Which species? 4. What is the common name for this parasite? 5. Which of the figures shown here, A or B, is most helpful for speciating this parasite? Why? 6. Note the differential characteristics of this species compared with those of its closest relative species.
