Which bacteria hosted by leeches is known to cause infection?

• A. Aeromonas hydrophilia
• B. Pseudomonas aeruginosa
• C. Staphylococcus aureus
• D. Escherichia coli

Answer: (A)

Aeromonas hydrophilia is a notable bacterium associated with leech therapy and is recognized for its potential to cause infections. This organism is commonly found in freshwater environments where leeches reside. If leeches that harbor Aeromonas are used in therapeutic or surgical applications, there is a risk of transferring these bacteria to the host, leading to infections that can manifest as cellulitis, gastroenteritis, or other systemic infections. This bacterium is particularly concerning in patients who may have compromised immune systems or open wounds, as their susceptibility to infections is increased. The fact that Aeromonas hydrophilia is opportunistic explains the clinical relevance when leeches are utilized in treatment or surgical settings involving soft tissue. Other bacteria such as Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli, though they are known pathogens, are not specifically associated with leeches or the infections derived from leech therapy. Each of these organisms can cause distinct types of infections under different circumstances, but they do not typically originate from the same context as Aeromonas hydrophilia in relation to leech-associated infections.
