Which organism is NOT among the four specifically listed in the compendium as shedding during birthing?

• A. Coxiella burnetii
• B. Brucella spp.
• C. Escherichia coli
• D. Leptospira spp.

Answer: (C)

Some pathogens are especially associated with birth materials and can be shed in placenta, membranes, and vaginal secretions, creating occupational exposure during parturition. In the compendium, the organisms highlighted as birthing-shedder hazards include Coxiella burnetii and Brucella spp. as classic examples, with Leptospira spp. also listed among those linked to obstetric material. Escherichia coli, while a common enteric bacterium that can be shed in various contexts, is not one of the organisms specifically identified as shedding during birth in that compendium. The takeaway is to recognize which pathogens are emphasized as birth-associated exposures so appropriate precautions (like PPE and safe handling of birth materials) are used when assisting with parturitions.
