“…Furthermore, cutaneous M. chelonae infection has been reported to occur after medical injection, 6 surgical procedures, 7 or catheter insertion 3 . Cutaneous M. chelonae infection exhibiting a sporotrichoid arrangement is, however, quite rare, and only seven cases have been described in the English literature 8–14 . These seven cases exhibited a unilateral distribution on either the arm or the leg.…”

“…fortuitum and M. chelonei are the only two members of Runyon's group IV category which are considered potential pathogens [II]. These ubiquitous environmental saprophytes establish infection in the skin, usually after injury, surgery, or injection [4,6,9,II). They are best identified in culture by their rapid growth rate of three to seven days, and arylsulfatase activity at three days [4,5).…”

Granulomatous skin lesions associated histologically with acid-fast bacilli have been reported in the dog, but the specific bacteria involved were not identified [3,7). The following report of nontuberculous mycobacterial skin infections in two dogs is the first in which the causative organisms have been isolated in culture and identified definitively. The work is of further importance because it indicates that routine and special staining of paraffin-embedded sections is not adequate to demonstrate certain of the nontuberculous mycobacteria in skin lesions.Dog I was a ten-year-old. male English setter with several nonpainful, nonpruritic cutaneous masses on the thorax which had been present for approximately five weeks. Two weeks before the swellings were first noted the dog had received subcutanous injections of a parvovirus vaccine and atropine near the skin lesions. A history of ulceration and drainage of the larger masses with subsequent development of new swellings at the edges of the older lesions was reported by the owners. Upon presentation. three large. semifirm, nodular. ulcerated swellings were observed in the skin of the upper left thorax. The largest lesion was excised for microbiological culture and histologic examination. After little response was obtained during three weeks of therapy with kanamycin (\60 mg TID), most of the remaining affected skin was excised.D6g 2, a seven-year-old male collie. had been bitten by another dog on the right side of the neck and shoulder. Surgical repair of the injury was followed over the next two months by the development of extensive. firm swellings and open draining lesions in the vicinity of the previous wounds. These persisted, resulting in presentation of the animal to the Veterinary Medical Teaching Hospital at the University of Florida. The lesions were cultured and biopsied. Due to the extent of diseased tissue. complete excision was not attempted and the dog was discharged with erythromycin (500 mg TID) and instructions for the owners to hot pack the affected area twice daily.Histologically. the biopsy specimens from both dogs were similar. The skin was ulcerated and had dermal and hypodermal pyogranulomatous inflammation. No true granulomas were observed. Neutrophils were gathered in small foci or formed thin rims around cleared spaces ( fig. I). Scattered. occasionally severe hemorrhage was seen. Granulation tissue was present beneath the inflamed area.

“…chelonae has been aetiologically implicated in several clinical syndromes which include not only organ-specific pathology but also disseminated disease [6]. Isolated cases are common [7][8][9][10][11][12][13][14] but outbreaks are not [15][16][17][18][19][20][21][22].…”

Iatrogenic outbreak of M. chelonae skin abscesses

SUMMARYWe describe an outbreak of skin lesions due to Mycobacterium chelonae subsp. abscessus associated with injections of lidocaine (lignocaine) given by a 'bioenergetic' (a practitioner of alternative medicine) in Colombia. The lidocaine carpules and the lesions of the patients yielded mycobacteria with identical biochemical characteristics.Using the methodology of Sartwell and a case control design we examined the incubation period and assessed risk factors. Of 667 potentially exposed individuals, a total of 298 patients were interviewed, of whom 232 had skin lesions. The median incubation period was 305 days (range 15-59 days). Male sex (OR 2-85, 95 % CI 126-6-5 1), increasing age (OR 1-25, 95 % CI 103-1-53), subcutaneous injection route (OR 3-72, 95 % CI 1-09-12-7) and number of injections (OR 101, 95% CI 1001-03) were risk factors for disease.To our knowledge, this is the largest reported outbreak of M. chelonae infection, the first in which the organism has been isolated from the putative vehicle of infection, and the first in which the incubation period could be determined.
