Antimicrobial and Antioxidant Activities of Two Medicinal Plants Cuphea aequipetala var. hispida (Cav.) Koehne and Eryngium comosum Delaroche F Against Bacteria Related to Equine Infections.
Abstract: Functional biocompounds beneficial for animals and humans are in Mexican folk herbs. Cuphea and Eryngium species presented antimicrobial potential. Natural antibiotic uses by ethnoveterinary research with medicinal plants in equine infection or digestive diseases need more scientific evidence. Staphylococcus aureus, Escherichia coli, Salmonella enterica serotype Enteritidis are etiological agents in horses responsible for stable infections, abortions, fetal or perinatal deaths, and resistant intrahospital infections. The main objective of the present research was to evaluate the potential of antimicrobial and antioxidant activities of two Mexican medicinal plants Cuphea aequipetala var. hispida (Cav.) Koehne and Eryngium comosum Delaroche F over Listeria monocytogenes ATCC 19115, Staphylococcus sp., E. coli ATCC 25922, and S. enterica serotype Enteritidis ATCC 13076 bacterium reference strains related to equine infections. Determination of total phenol, saponins, antioxidant activity (ABTS), and antimicrobial activity with diffusion-sensitive discs was performed in triplicate. All the strains were sensitive for both extracts except for E. coli strain that was inhibited only by C. aequipetala. Staphylococcus sp. and S. enterica strains were inhibited equally by both extracts. E. comosum extracts tested have shown the highest effect over L. monocytogenes. In summary, antimicrobial activity was similar to the reported activity of Eryngium species extracts with other different solvents. Present extracts are suggested as a potential alternative antibiotic; definitely, more specific equine pathogen inhibition tests are needed in feed additives for horse nutrition research. In conclusion, antimicrobial activities of Cuphea aequipetala var. hispida (Cav.) Koehne and Eryngium comosum Delaroche F over reference strains related to equine infections suggested these medicinal plants as potential antibiotic sources for horse diseases.

This research is about the antimicrobial and antioxidant properties of two Mexican medicinal plants, Cuphea aequipetala var. hispida Koehne and Eryngium comosum Delaroche F, against bacteria responsible for horse diseases.
Objective and Background
- The research aimed to investigate the potential antimicrobial and antioxidant activities of two Mexican medicinal plants—Cuphea aequipetala var. hispida (Cav.) Koehne and Eryngium comosum Delaroche F—against four bacterial strains related to horse infections.
- This study arises from the need for more scientific evidence of ethnoveterinary uses and the potential applicability of natural antibiotics for equine infections or digestive diseases.
Methods
- The total phenol, saponins, and antioxidant properties (ABTS) of the plants were analyzed. Also, antimicrobial activity was tested with diffusion-sensitive discs in triplicate.
- The bacterial strains tested included Listeria monocytogenes ATCC 19115, Staphylococcus sp., E. coli ATCC 25922, S. enterica serotype Enteritidis ATCC 13076, all of which are implicated in serious infections in horses.
Results
- The results showed that both plant extracts were effective against all bacterial strains tested, except E. coli which was inhibited only by C. aequipetala.
- The Staphylococcus sp. and S. enterica strains were equally inhibited by both extracts.
- The E. comosum extracts showed the highest effect against L. monocytogenes.
Implication and Conclusion
- The research backs previous findings that suggest the antimicrobial activity of Eryngium species extracts with different solvents.
- The study suggests that the extracts of these plants could potentially be developed as alternative antibiotics, though more specific tests are needed, particularly in feed additives for horse nutrition research.
- In conclusion, the research validates the potential of Cuphea aequipetala var. hispida (Cav.) Koehne and Eryngium comosum Delaroche F as natural sources of antibiotics for treating horse diseases.
