And Malaseb (from bullwrinkle.com)
Malaseb Shampoo is ideal for generalized or multifocal therapy of dermatitis in dogs, cats and horses. Malaseb Shampoo contains Miconazole – an antifungal with potent activity against fungi and yeast – and Chlorhexidine Gluconate – a proven antimicrobial agent active against gram-positive and gram-negative bacteria. This synergistic formulation effectively removes scales, degreases the skin and kills cutaneous microorganisms that primarily or secondarily cause dermatitis. Clinical trials show Malaseb shampoo to be an effective treatment and control of Seborrheic dermatitis associated with Malassezia pachydermatitis and Staph intermedius. Malaseb shampoo is free from dyes and perfumes to reduce possible exacerbation of skin problems and its innovative surfactant base removes damaged lipids without stripping the coat. Malaseb shampoo was shown to accelerate the resolution of Microsporum Canis (ringworm), reducing the risk of transmission of the disease to other animals and to humans in contact with them.
