Objective: to report the isolation of Dermatophilus congolensis from paint-brush matted hairs to wart-like skin lesions in 12.1% of quarantined local cattle from the Sultanate of Oman.

Methodology: skin scrapings, blood samples and skin biopsies were aseptically collected from the affected cattle for bacteriological, hematological and histopathological ex- aminations, respectively.

Results: bacterial cultural and staining characteristics of skin scrapings were confined with D.

congolensis.

Neutrophilia were reported in 86.75% of the examined animals.

Histologically, there was severe multifocal exudative dermatitis with hyperkeratosis.

Affected animals were treated successfully with three doses of long-acting oxytetracycline (20 mg/kg; IM injection) with topical application of antibiotic spray.

Conclusion: this is the first report of dermatophilosis in local Omani cattle, and field veterinarians should be kept up to date with this recent detecteddisease.
