Riesgo de infección por Aeromonas
15–30%
Without prophylaxis
2–5%
With prophylaxis
Aeromonas hydrophila is a gram-negative bacterium symbiotic with medicinal leeches. Without antibiotic prophylaxis, infection rates range from 15–30%. Mandatory prophylaxis reduces this to 2–5%, making infection a manageable risk when protocols are followed.
