Evaluation of three different histamine concentrations in intradermal testing of normal cats and attempted determination of 'irritant' threshold concentrations for 48 allergens.

The purpose of this study was to determine the optimal histamine concentration and 'irritant' allergen threshold concentrations in intradermal testing (IDT) in normal cats. Thirty healthy cats were tested with three different histamine concentrations and four different concentrations of each allergen. The optimal histamine concentration was determined to be 1: 50,000 w/v (0.

Determination of threshold concentrations of allergens and evaluation of two different histamine concentrations in canine intradermal testing.

The purpose of this study was to determine the optimal histamine concentration and allergen threshold concentrations for canine intradermal testing. Thirty healthy dogs were tested using two different concentrations of histamine and four different concentrations of each allergen. The optimal histamine concentration was determined to be 1:10 000 w/v.

Immunotherapy for treatment of multicentric cutaneous pythiosis in a dog.

A 4-year-old Labrador Retriever was referred for evaluation of 2 ulcerative nodular cutaneous lesions. One lesion was located on the medial aspect of the right carpus; the other was located on the medial aspect of the left tarsus. The dog had spent its entire life in the southeastern part of the United States and approximately half of its time outdoors with free access to a nearby lake.

Effect of topical application of fipronil in cats with flea allergic dermatitis.

Objective: To determine whether topical application of a 10% fipronil solution would control signs of flea allergic dermatitis in cats housed under natural conditions.

Design: Multicenter open clinical trial.

Animals: 42 client-owned cats with flea allergic dermatitis.

Dermatophyte granulomas caused by Trichophyton mentagrophytes in a dog.

Multiple, dermal and subcutaneous nodules developed in a young female Manchester Terrier dog that had a chronic history of superficial dermatophytosis. Skin biopsy specimens of the nodules revealed granulomatous inflammation in the deep dermis and subcutis with branching fungal organisms. Cultures of multiple biopsy specimens from the nodules all yielded Trichophyton mentagrophytes.

Evaluation of topically applied enilconazole for the treatment of dermatophytosis in a Persian cattery.

Many Persian catteries have long-standing dermatophyte infections and are particularly difficult to treat. Enilconazole is a topical antifungal agent that has demonstrated good efficacy in recent studies. Twenty-two Persian cats naturally infected with Microsporum canis in a breeding cattery were treated with topical 0.

Daily ivermectin for treatment of generalized demodicosis in dogs.

Abstract  Twelve dogs with generalized demodicosis were treated with oral administration of ivermectin, 0.4 mg kg of body weight given once every 24 h. Results of skin scrapings were used to determine whether administration of ivermectin should be continued or stopped.
