PROCEDURE: Seven dogs (four Boxers, one Dobermann, one Bullmastiff and one Bullmastiff cross-bred; ages 3 to 11 years) with leproid granulomas were treated successfully using a variety of treatment regimens. Canine leproid granuloma (CLG) is a cutaneous or subcutaneous, typically self-limiting nodular mycobacteriosis caused by a novel mycobacterium yet to be fully characterized. Leproid granulomas are confined to tbe subcutis and skin and do not involve regional lymph nodes, or internal organs. Please check your email for instructions on resetting your password.

With M. ulcerans, M. fortuitum, M. goodii and M. smegmatis infections, lesions are usually confined to the skin, with leprosy-like dermal ulcers and panniculitis. Mycobacterial culture – This doesn’t work as it does for other bacterial organisms because growth requirements for this bug have not yet been determined.TREATMENT: 1. The pathology of canine leproid granuloma syndrome is highly uniform and is suggestive of saprophytic mycobacterial involvement. Number of times cited according to CrossRef: Journal of the American Veterinary Medical Association. The canine leproid granuloma syndrome or canine leprosy, as it is also known, is a nodular pyogranulomatous disease that affects the skin and the subcutaneous tissue of dogs, caused by a species of mycobacteria still untyped. BACKGROUND: Canine leproid granuloma (CLG) characteristically presents as single to multiple circumscribed dermal to subcutaneous nodules in haired skin. Clinically it is presented as a nodular, hard, painless, some-times ulcerated lesion. Canine leproid granuloma syndrome or canine leprosy was first described in 1973 in Zimbabwe. In 1998, the term canine leproid granuloma syndrome was coined to describe a nodular pyogranulomatous disease affecting the skin and subcutis of dogs (4, 25).This condition, first described in 1973 in Africa (), is the most common mycobacterial disease of dogs in Australia and affects principally short-coated breeds ().

This disease, referred to often as canine leprosy, is the most common mycobacterial disease of dogs in Australia, it has also been reported in New Zealand, Brazil, Zimbabwe, California and Florida. Further work is required to determine the most cost effective treatment regimen for this condition. strain Tarwin affecting a cat from the Central Coast of New South Wales.

Affected dogs appear otherwise healthy, and in the majority of cases the lesions tend to heal spontaneously over the course … The cause and spread of the disease are not fully understood at this time but an environmental mycobacterium (such as found in soil, water) is thought to be inoculated into the skin by biting insects or poetntialy other methods. The disease has also been seen in other areas of the US. Infectious Nodular and Diffuse Granulomatous and Pyogranulomatous Diseases of the Dermis.
