What is a common symptom of infections caused by Enterobacteriaceae?

• A. Skin rashes
• B. Gastrointestinal disturbances
• C. Respiratory distress
• D. Neurological issues

Answer: (B)

Infections caused by Enterobacteriaceae, which includes pathogens such as Escherichia coli, Klebsiella pneumoniae, and Salmonella spp., often present with gastrointestinal disturbances. This is mainly because these bacteria are usually associated with the gastrointestinal tract, leading to symptoms such as diarrhea, abdominal pain, nausea, and vomiting. The ability of Enterobacteriaceae to produce toxins or directly invade the intestinal lining can exacerbate these gastrointestinal symptoms. For instance, enterotoxigenic E. coli is known to cause severe diarrhea due to toxin production. Similarly, infections caused by other members of this family can disrupt normal gut flora and result in various levels of gastrointestinal dysfunction. While skin rashes, respiratory distress, and neurological issues can occur with some infections, they are not typically associated with Enterobacteriaceae. These bacteria are most commonly linked to gastrointestinal manifestations, making gastrointestinal disturbances the most accurate symptom to identify.
