Diagnosis
1. Blood Specimens - Safety

Follow universal precautions for the prevention of bloodborne pathogens when working with human serum and other body fluids. These include:
1. Wear personal protective equipment such as safety glasses, gloves, laboratory coats.
2. If you have cuts or abrasions on the skin of your hands, cover them with adhesive dressing.
3. Use needles and lancets only once, and dispose of them in a “sharps” container for decontamination.
4. Remove gloves and wash your hands after completing any task involving the handling of biological material.

Stool Specimens - Safety
Laboratorians working with stool specimens face potential risks including ingestion of eggs or cysts, skin pe*******on by infective larvae, and infection by nonparasitic agents found in stool and biologic fluids. These risks can be minimized by adopting universal precautions as well as standard microbiological laboratory practices (Biosafety Level 2). These include:
 Wear protective safety glasses, gloves and laboratory coat when processing specimens.
 Use biological safety cabinets as needed.
 Do not eat, drink, smoke, apply cosmetics or manipulate contact lenses in work area.
 Decontaminate work surface at least once a day and after any spill of potentially infectious material.
 If you have cuts or abrasions on the skin of your hands, cover them with adhesive dressing.
 If you use any sharp instruments, dispose of them in a “sharps” container for decontamination.
 Remove gloves and wash your hands after completing any task involving the handling of f***l material.
Note: These precautions should be taken even with stool specimens that have been fixed in preservatives because they may still be infectious. For example, fixation in formalin takes days or weeks to kill some parasite cysts or oocysts that are protected by a thick shell. Eggs of Ascaris lumbricoides may continue to develop and are infectious even when preserved in formalin.

Case Study #
A 6-year-old boy from a very low socioeconomic status family, who had a history of pica, was admitted to the emergency department with complaints of pain in the abdomen, abdominal distension, vomiting, and constipation for the past four days and fever for the past two days. On physical examination he appeared poorly nourished and febrile. Laboratory investigations revealed an elevated leukocyte count and increased eosinophils. An abdominal radiograph showed bowel obstruction with multiple air-filled levels. Ultrasonography demonstrated parallel paired lines in the intestinal lumen.
1. Which nematode would you suspect of causing this condition?
2. What is the infective form of the parasite?
3. Clinical suspicion of the infection which test may use to confirm this infection?

Case II #

After one week vacationing in Mexico, a 14-year-old girl presents with abdominal pain, nausea, bloody diarrhea, and fever. Stool specimens are collected and sent to the laboratory for bacteriologic and parasitologic examination. Bacterial cultures are negative for intestinal pathogens. The laboratory report reveals organisms with red blood cells inside them. The most likely causal agent

a. Entamoeba histolytica
b. Giardia lamblia
c. Trichomonus vaginalis
d. All of the above
