Final answer:
In the given scenarios, A) hospitalized for AB treatment can involve bacteria like MRSA, B) travelers to less developed countries can be at risk for ETEC infection, C) becoming ill after an event with bloody diarrhea can indicate STEC infection, and D) daycare workers with bloating may have giardiasis.
Step-by-step explanation:
In the given scenarios, the bugs and treatments are as follows:
- A. In the case of being hospitalized for AB (antibiotic) treatment, common bugs can include methicillin-resistant Staphylococcus aureus (MRSA) or other antibiotic-resistant bacteria. The treatment would depend on the specific bug and may involve the use of different antibiotics to target the infection.
- B. Travelers to less developed countries are at risk for various gastrointestinal infections, including enterotoxigenic Escherichia coli (ETEC). The bug can be transmitted through contaminated food or water. Treatment may involve supportive care, such as rehydration, and antibiotics if necessary.
- C. In the case of becoming ill after an event where food is served, and others have similar symptoms and bloody diarrhea, a possible bug could be Shiga toxin-producing Escherichia coli (STEC). This bug can cause bloody diarrhea and is often associated with undercooked ground beef and contaminated produce. Treatment is mainly supportive, including rehydration, and antibiotics are generally not recommended.
- D. Daycare workers with symptoms such as bloating, flatulence, and foul-smelling stools may be experiencing a gastrointestinal infection called giardiasis. The bug responsible is a parasite called Giardia lamblia. Treatment usually involves a course of antiparasitic medications.
