Two Collie working dogs were examined because of the sudden appearance of a skin condition. Both dogs were depressed and anorectic with an acute exudative dermatitis confined to areas of non-pigmented skin. Antibacterial treatment was instituted initially followed by long-term use of a sun-protective cream. A diagnosis of photosensitive dermatitis was made but the cause of the photosensitivity was not determined. 相似文献

A retrospective study of the histological features of four cases of canine Trichophyton menta-grophytes var erinacei infection is reported. In all four dogs the initial lesions affected the dorsal muzzle and in two dogs the lesions spread to more distant sites on the body. Clinically, the lesions were characterized by scaling, crusting and hair loss. Histologically, the main lesions were characterized by acanthosis, epidermal, ostial and infundibular hyperkeratosis, serocellular crusting, mural folliculitis and furunculosis. Fungal hyphae were usually sparse and often difficult to see in haematoxylin and eosin stained sections. When visible they were seen in the epidermal, ostial and infundibular scale and, less frequently, within hair shafts. 相似文献

Six cases of Rhodococcus equi infection in cats are described. One cat had pneumonia and died. The remaining five cats had cutaneous lesions affecting the feet in four of the cats and the metacarpus in one cat, and all these cats recovered with the aid of antibiotics. All the Rhodococcus equi isolates were sensitive to amoxycillin/clavulanic acid and, where used, at least 14–16 days of treatment was needed to help eliminate the infection. Histologically and cytologically the reaction was pyogranulomatous and many macrophages in the lesions contained large numbers of Gram-positive bacteria. 相似文献

Red blood cells from 6 Pygmy goats were determined to be significantly (P less than 0.01) more susceptible to osmotic lysis and mechanical stress than were RBC from 6 Toggenburg goats. Differences in RBC size and shape and adenosine 5'-triphosphate concentration between the 2 breeds were not significant. The differences observed in the in vitro tests may be attributable to differences in RBC membrane composition. 相似文献

CASE HISTORY: A 3-month-old female Angus calf was found dead, and two adult Friesian dairy cows died soon after developing nervous signs. PATHOLOGICAL FINDINGS: Grossly, bilateral and mostly symmetrical areas of haemorrhage were evident that mainly involved areas of grey matter in the brainstem from the level of the caudal colliculi to the thalamus and, in one, the internal capsule and caudate nucleus. In the occipital and caudal parietal cortex, there was extensive oedema of white matter. Histologically, in addition to haemorrhage, there was protein-rich oedema around arterioles and venules in the cerebrum, hippocampus, internal capsule, thalamus, midbrain, dorsal medulla, and central cerebellar and cerebellar folial white matter. The calf 's brain had bilateral and symmetrical oedema and necrosis affecting several brainstem nuclei and the occipital grey matter overlying areas of oedema of the corona radiata. DIAGNOSIS: Although the cause was not established, the perivascular lesions resembled those produced in calves by the intravenous administration of epsilon toxin. CLINICAL RELEVANCE: It is possible that epsilon toxin-induced enterotoxaemia occurs naturally in cattle, and where bilateral haemorrhage is recognised in the brains of cattle, small intestinal contents should be collected for analysis of epsilon toxin. 相似文献
