A. Listeria monocytogenes is a food borne pathogen
B. Humans are probably accidental hosts for this microorganism
C. Case-fatality rate of listeria meningitis is reported to be 15-26%
D. Granulomatosis infantiseptica is an overwhelming listerial fetal infection with miliary micro abscesses and granulomas
E. Adults should receive IV ampicillin at high doses (2 grams every 4 hours)

**Correct Answer:**

**A. Listeria monocytogenes is a food borne pathogen:**

Listeria monocytogenes is indeed a food-borne pathogen, meaning it is commonly transmitted through consumption of contaminated food products. It can cause various infections in humans, including meningitis, septicemia, and gastroenteritis. The bacterium's ability to survive and grow in refrigerated foods contributes to its transmission.

**B. Humans are probably accidental hosts for this microorganism:**

Humans are considered accidental hosts for Listeria monocytogenes, meaning they are not the natural reservoir for the bacterium. The bacterium primarily infects warm-blooded animals, causing listeriosis in these hosts. Humans acquire the infection through consumption of contaminated food products or direct contact with infected animals.

**C. Case-fatality rate of listeria meningitis is reported to be 15-26%:**

The case-fatality rate of listeria meningitis can vary depending on factors such as the patient's age, underlying health conditions, and timely initiation of appropriate treatment. In the context of this question, the case-fatality rate is stated as 15-26%. This high rate highlights the severity of the disease and emphasizes the importance of early diagnosis and appropriate treatment.

**D. Granulomatosis infantiseptica is an overwhelming listerial fetal infection with miliary microabscesses and granulomas:**

Granulomatosis infantiseptica is an uncommon term used to describe listeriosis in neonates. Miliary microabscesses and granulomas are features of severe listeriosis, which can occur in neonates, elderly, or immunocompromised individuals. However, this specific term is not commonly used in modern medical literature.

**E. Adults should receive IV ampicillin at high doses (2 grams every 4 hours):**

For adults with listeriosis, intravenous ampicillin is a widely used antibiotic treatment. Dosage depends on the severity of the infection and the patient's renal function. The
