Residual Antibacterial Activity of Canine Hair Treated with Five Mousse Products Against Staphylococcus Pseudintermedius In Vitro

The study evaluated the residual antibacterial activity of five mousse products on canine hair against Staphylococcus pseudintermedius. Fifteen dogs with no dermatological issues were treated with mousses containing various active ingredients. Hair samples were collected and tested for bacterial growth inhibition over 14 days. Results showed that mousses containing chlorhexidine and either ketoconazole, miconazole, or climbazole (mousses 1, 2, and 3) significantly inhibited bacterial growth for up to 10 days, with mousse 3 maintaining significant inhibition up to 14 days. Mousses containing salicylic acid with ethyl lactate and phytosphingosine HCl (mousses 4 and 5) showed no significant antibacterial activity. The study concluded that three mousse products demonstrated residual antibacterial effects for at least 10 days.
