“…Botryomycosis is described in equids, ruminants, pigs, companion animals, guinea pigs, rabbits, elephants, primates and humans (Bender‐Saebelkampf et al, 2019; Bostrom et al, 1969; Brack et al, 1997; Casamián‐Sorrosal et al, 2008; Hedley et al, 2019; Johns et al, 2014; Loader et al, 2018; Merchan et al, 2019; Miller et al, 2001; Share & Utroska, 2002; Sleeman et al, 2003). Two main forms have been described, depending on the localisation of the primary lesion: a more common cutaneous form and a visceral form (Winslow, 1959).…”

Summary Botryomycosis is an uncommon chronic bacterial pyogranulomatous infection of cutaneous and, rarely of visceral origin, that can rarely invade the osseous tissues. An 8‐year‐old Friesian gelding was presented with severe bilateral hindlimb ataxia and paresis of 2‐weeks' duration. Radiographic examination revealed a large osteolytic lesion at the T10‐T11 intervertebral disc space. Post‐mortem examination revealed discospondylitis with abscess formation and histological presence of pyogranulomatous inflammation with coccoform bacteria rimmed by Splendore‐Hoeppli material. Staphylococcus aureus was identified by bacteriological examination. This case report describes the clinical presentation, imaging features and post‐mortem findings of a Friesian gelding presenting with severe bilateral hindlimb ataxia and paresis caused by compression and degeneration of the spinal cord due to a botryomycosis‐like thoracic discospondylitis. Botryomycosis‐like infection should be considered in the differential diagnosis of focal expansile bone lesions demonstrating diffuse osteolysis, sclerosis and interrupted bone margins.

“…B otryomycosis (also known as staphylococcic actinophytosis; granular bacteriosis; bacterial pseudomycosis; actinobacillosis; bacterial pseudomycetoma; and cutaneous bacterial granuloma) is a rare skin disease in humans and animals. As well as humans, it has been reported in horses, cattle, sheep, dogs, cats, pigs, mice, a zebra, a hamster, 1 African elephants, barbary ape, harp seals, 2 and a captive echidna. 3 It is a chronic bacterial infection of the skin and viscera caused by nonfilamentous bacteria inducing the formation of grains and granules in tissues.…”

Cutaneous botryomycosis in a free‐living short‐beaked echidna (Tachyglossus aculeatus)

Botryomycosis is a chronic bacterial infection of the skin and viscera caused by nonbranching bacteria such as Staphylococcus spp. It results in the formation of chronic, suppurative and often granulomatous lesions that may resemble multiple abscesses. It has been diagnosed worldwide in both humans and animals. It is a rare disease, usually requiring surgical excision combined with long-term antibiotics to achieve a good resolution. A wild echidna (Tachyglossus aculeatus) was presented with a soft tissue mass at the base of the right distal beak with multiple discharging fistulas arising from it. The mandible appeared to be shortened and deviated to the right, and the animal was unable to close its beak. The echidna was in poor body condition and was euthanased on welfare grounds. Histopathology of the lesions demonstrated the classical botryoid lesions with the characteristic Splendore-Hoeppli reaction surrounding the bacterial colonies, in a background of extensive granulation tissue. Radiographs revealed mild mandibular osteomyelitis, yet haematology and biochemistry results were nonspecific. This disease has not previously been reported in a wild monotreme.

A 10-month-old male guinea pig was presented with an area of alopecia and pruritus on the back. This progressed over 6 months to an ulcerated, painful skin mass. The aim of this report was to illustrate the unique cytological appearance of the Splendore-Hoeppli (SH) reaction, which has rarely been described in veterinary medicine. The mass was sampled using a fine-needle aspiration technique for cytological examination and bacteriological culture. Following cytological diagnosis and bacteriological results, the mass was surgically excised and histopathological examination was performed. Cytological examination of the mass revealed pyogranulomatous inflammation with filamentous bacteria identified by culture to be Actinomyces spp. The bacteria were often coated with a moderate amount of red to blue staining material, interpreted to represent the SH reaction. Histopathological examination confirmed the presence of the Splendore-Hoeppli phenomenon (SHP). The appearance of SH in histological specimens is well described in veterinary medicine, but the cytological appearance is not well recognized. This report illustrates well the cytological description of the material which should be recognized as a part of the immune response to insult, and not be mistaken as foreign material.
