Progressive ataxia and paralysis in three Miniature Dachshunds were found to be caused by idiopathic sterile pyogranulomatous inflammation of epidural fat between T5 and L4. All dogs were managed by hemilaminectomy and removal of epidural compressive material. Surgical findings and histopathological evaluation were necessary to diagnose epidural pyogranulomatous inflammation. A dog did not rega...

A male Thoroughbred fetus was aborted on day 251 of pregnancy. Gross and histological examinations detected systemic granulomatous lesions in many superficial and visceral lymph nodes and organs including the liver, tonsils, lungs, thymus, spleen, right thyroid gland and gastrointestinal tract, and suppurative placentitis, pyogranulomatous amnionitis and intralesional acid-fast bacilli were als...

We report a case of pyogranulomatous pneumonia due to infection with Mycobacterium goodii in an adult female spotted hyena (Crocuta crocuta). The lungs of the animal showed consolidated, granulomatous lesions, and they were extensively and severely infiltrated. Polymerase chain reaction sequencing of isolated crude lung tissue DNA, and boiled lung culture samples, all confirmed that the causati...

Abstract Infections with Mycobacterium microti, a member of the M. tuberculosis complex, have been increasingly reported in humans and domestic free-ranging wild animals. At postmortem examination, infected animals may display histopathologic lesions indistinguishable from those caused by bovis or caprae, potentially leading to misidentification bovine tuberculosis. We report 3 cases microti in...

Recent isolations of Rhodococcus equi from cavitatory pulmonary disease in patients with AIDS have aroused interest among medical microbiologists in this unusual organism. Earlier isolations from humans had also been in immunosuppressed patients following hemolymphatic tumors or renal transplantation. This organism has been recognized for many years as a cause of a serious pyogranulomatous pneu...

A four-year-old, neutered male Labrador retriever from Minnesota, USA was presented to a dermatology referral clinic for evaluation of waxing and waning paronychia and multifocal cutaneous nodules of five months’ duration. The condition was managed before referral with antibiotics and glucocorticoids resulting in a partial response, but new lesions continued to develop. Skin biopsies made both ...

ABSTRACT: In this retrospective study, the clinical and anatomopathological findings of fungal diseases in dogs cats Northeastern Brazil are described. During study period, 6,827 histopathological examinations (4,090 necropsies 2,737 biopsies) companion animals were reviewed, infections diagnosed 54 cases. Of these, 32 cases 22 dogs. Sporotrichosis was most prevalent mycosis (19/54), followed b...
