ABSTRACT
Yeast infections such as otitis externa and seborrheic dermatitis in dogs and cats are frequently associated with Malassezia pachydermatis secondary infection. It is part of the normal cutaneous microflora of most warm-blooded vertebrates, however, under certain conditions, it can become a causative agent of infection that needs to be treated pharmacologically. Azole derivatives are the drugs of the first choice. An interesting trend in developing resistance is the use of natural substances, which include manuka honey with confirmed antimicrobial properties. The main intention of this research was to evaluate the mutual effect of manuka honey in combination with four conventional azole antifungals - clotrimazole, fluconazole, itraconazole, and miconazole - on 14 Malassezia pachydermatis isolates obtained from dogs and 1 reference strain. A slightly modified M27-A3 method (CLSI 2008) and the checkerboard test (Nikolic et al. 2017) were used for this purpose. Our results show an additive effect of all 4 antifungals with manuka honey concurrent use. Based on the determined values of fractional inhibitory concentration index (FICI - 0.74±0.03 when manuka honey combined with clotrimazole, 0.96±0.08 with fluconazole, 1.0±0 with miconazole and 1.16±0.26 with itraconazole), it was found in all cases that the effect of substances used is more pronounced in mutual combination than when used separately.
