Background: Chronic and recurrent pyoderma in dogs is driving a growing interest in natural antimicrobial products that offer minimal adverse effects and avoid antibiotic resistance.
Objectives: Evaluate the safety and efficacy of dermatological products with antimicrobial peptides and plant extracts, comparing them to chlorhexidine + miconazole and cephalexin therapy for superficial pyoderma in dogs.
Materials And Methods: Forty-five dogs with superficial pyoderma underwent clinical, cytopathological and microbiological diagnosis, and were randomly assigned to Group 1 (G1) treated with shampoo (two weekly baths) and lotion (twice daily on the affected areas) containing natural antimicrobials; Group 2 (G2) treated with two weekly baths using a therapeutic shampoo containing 2% chlorhexidine and 2.

Chronic infections represent a significant global health and economic challenge. Biofilms, which are bacterial communities encased in an extracellular polysaccharide matrix, contribute to approximately 80% of these infections. In particular, pathogens such as Pseudomonas aeruginosa and Staphylococcus aureus are frequently co-isolated from the sputum of patients with cystic fibrosis and are commonly found in chronic wound infections.

Skin grafting techniques are widely used for large burns, trauma, and various acute and chronic wounds, contributing greatly to the repair of traumatic tissue. However, donor site repair and regeneration are often neglected, resulting in infection and delayed healing. Therefore, it is crucial to reduce the rate of donor site infection and improve the speed and quality of healing.

Peptides are molecules that consist of at least two amino acids linked by peptide bonds. The difference between peptides and proteins is primarily based on size and structure. Typically, oligopeptides consist of fewer than about 10-20 amino acids, and polypeptides consist of more than 20 amino acids, whereas proteins usually are made up more than 50 amino acids and often contain multiple peptide subunits as stated in the International Union of Pure and Applied Chemistry rules.
