The Discovery: A Novel Antibacterial Source
A bacteria of the genus Chryseobacterium, found within a leech species native to Mexico, produces compounds that inhibit the growth of Staphylococcus aureus, a common and increasingly drug-resistant pathogen responsible for many hospital-acquired infections. This finding was reported by researcher Deyanira Pérez Morales from the Center for Genomic sciences at the National Autonomous University of Mexico (UNAM) on Tuesday, November 11, 2025, in La Jornada.
Pérez Morales explained that antimicrobial resistance occurs when medications-including antibiotics, antivirals, and antifungals-lose their effectiveness in combating infections. This is a significant global public health concern.
The Growing Threat of Antibiotic resistance
The overuse and misuse of antibiotics in both human and animal populations are driving the rise of antibiotic-resistant pathogens. This creates a perilous situation,as therapeutic options for treating infectious diseases are dwindling.As Pérez morales noted in her interview with La Jornada, people are already dying from infections caused by bacteria resistant to all available antibiotics.
The World Health Organization (WHO) identifies antimicrobial resistance as one of the top 10 global public health threats to humanity (WHO, 2024). The economic burden of antimicrobial resistance is also considerable, increasing healthcare costs and reducing productivity.
Here’s a breakdown of the increasing rates of antibiotic resistance in the US:
| Pathogen | Resistance Rate (2023) | Source |
|---|---|---|
| Staphylococcus aureus (MRSA) | 35.9% | |
| Escherichia coli (CRE) | 14.7% | |
| Neisseria gonorrhoeae | 5.6% |
Why Leeches? An Unexpected Source
Leeches, while often viewed negatively, live in complex microbial ecosystems. Their bodies harbor a diverse range of bacteria, some of which may produce compounds with medicinal properties. The unique environment within a
