Plain-English summary
A group of foxhounds in New Zealand developed skin nodules known as canine leproid granulomas, which are caused by an unidentified mycobacterium. The affected dogs had multiple lumps under their skin and were treated with topical and/or systemic antimicrobial medications. Fortunately, all the dogs recovered after receiving treatment. This situation also included similar outbreaks in foxhounds in Australia, highlighting a concerning trend among closely related dogs in the same environments.

Abstract
BACKGROUND: Canine leproid granuloma (CLG) characteristically presents as single to multiple circumscribed dermal to subcutaneous nodules in haired skin. An unidentified mycobacterium is considered be the aetiological agent of this entity. ANIMALS: Several cases of canine leproid granulomas occurred in dogs in New Zealand during 2010 and 2011. Cases appeared in clusters, affecting multiple closely related foxhounds domiciled in the same kennels. All affected hounds recovered after topical and/or systemic antimicrobial therapy. Two similar outbreaks that occurred in foxhounds near Melbourne, Australia are also reported. METHODS: Cases were investigated using cytological, histological, microbiological and several molecular techniques. An environmental epidemiological study was also performed. RESULTS: A diagnosis of CLG was established in 11 dogs. Molecular identification of the causative agent confirmed that it was a mycobacterial species with 100% sequence homology within the amplified regions of the 16S rRNA gene and internal transcribed spacer (ITS1) with that found in association with similar infections from the USA, Brazil and Australia. CONCLUSION AND CLINICAL IMPORTANCE: This report details the first occurrence of multiple cases of CLG occurring in in-contact dogs and the first proven case of CLG in dogs in New Zealand.
