A Natural Solution for California's Herds: African Catfish Peptides

California's cattle producers and agricultural communities are all too familiar with the rising challenge of antibiotic resistance, making common bacterial infections harder to treat in livestock. But imagine a future where we could tackle these infections with a natural, powerful alternative. Our research points to just that: antimicrobial peptides (AMPs) found in African catfish.

We're really excited about these peptides because African catfish thrive in pathogen-rich freshwater, naturally producing these robust immune compounds in their skin mucus as a defense. This natural origin makes them highly appealing alternatives to synthetic drugs.

Predicted Safety and Potent Action

One of the most compelling aspects of these AMPs is their predicted safety for mammals. Our initial computer analyses suggest that various catfish AMPs are generally recognized as safe (GRAS). We predict they'll be absorbed in the human intestine without causing liver, brain, or heart toxicity. Furthermore, lab tests on a promising peptide, NACAP-II, confirmed it was non-hemolytic, meaning it didn't damage rabbit red blood cells—a strong indicator of its potential safety for mammalian cells.

Beyond safety, these peptides demonstrate effectiveness against problematic bacteria. One study revealed NACAP-II's strong activity against Extended-Spectrum Beta-Lactamase (ESBL)-producing Escherichia coli—a critical concern for both animal and human health due to its resistance to many common antibiotics. Another peptide, ACAP-IV, also showed antibacterial activity against E. coli and Staphylococcus aureus. We believe these AMPs work by directly disrupting bacterial cell membranes, a mechanism that makes it harder for bacteria to develop resistance compared to how they resist traditional antibiotics.

Unvented Designs

Some structures are now designed without the need for venting. Further information regarding this topic is being developed.

Side of House

The side of a house is vulnerable to wildfire. Siding can be vulnerable at lap joints. Combustible siding can threaten other parts of the house if it ignites and the resulting flame impinges on the window, or spreads to the eave area and threatens under-eave or gable end vents.

Homeowner's Wildfire Mitigation Guide: Page

Eaves

The under-eave area is vulnerable if embers enter the attic area through any gaps that may exist in this area, or if flames from ignited vegetation, siding, or other near-home combustible materials reach the area.

Appendix E: Wood decay

Decay (sometimes referred to by homeowners as "rot") is typically found at joints that trap water and dry slowly. Decay occurs only where wood has contact with water, such as trapped rain or condensation of water vapor moving out of the house. The wood then is a food source for the decay fungi.
