Neuropathological examination of the central nervous system of 13 naturally and 13 experimentally feline immunodeficiency virus (FIV)-infected cats revealed diffuse gliosis of gray and white matter and vacuolar myelinopathy in a large proportion of infected animals, sometimes associated with lymphocytic meningitis. Multinucleated giant cell formation, the(More)
Adrenalectomy has been shown to reverse most facets of the syndrome of the genetically obese fa/fa rat. However, a detailed analysis of the hypothalamo-pituitary-adrenal (HPA) axis in these animals is lacking. In the present study, morning corticosteronemia was higher in obese rats of both sexes than in lean ones, whereas evening corticosteronemia was(More)
To gain further information on diabetes-related disorders in the somatotrophic and lactotrophic axes, we undertook a functional, morphometrical and densitometrical study of the arcuate nucleus (AN), median eminence (ME) and anterior pituitary gland of adult male rats one month after streptozocin-induced diabetes (STZ-D). The basal secretory activity of(More)
A case of leishmaniosis in domestic cats (Felis catus domesticus) is described. The subject showed a nodular lesion on the eyelid. The diagnosis was achieved by serological, parasitological, and light and electron microscopic investigations. By molecular techniques the aetiological agent was identified as belonging to Leishmania infantum, the species(More)
The aim of this study was to investigate the anatomical distribution of microfilariae of a recently described Cercopithifilaria sp. and the relationship with the preferred attachment sites of its vector, the brown dog tick Rhipicephalus sanguineus. Skin samples from 20 dogs were collected from eight anatomical sites and soaked twice in saline solution at(More)
A case of feline cutaneous phaeohyphomycosis due to Cladophyalophora bantiana is described. The cat was presented with breathing difficulty and a swollen, ulcerated nodule on the dorsal nose and left nostril. Histological examination of the nodule revealed a cystic granulomatous dermatitis characterised by neutrophils, macrophages and giant cells.(More)
The clinical signs and histopathological features of a primary extragenital canine transmissible venereal tumour (TVT) are described. Three subcutaneous round alopecic nodules were located on the anterior and caudal dorsal region and in the ventral area of the neck. Cytologically, tumour cells were intermediate in size with a moderate amount of cytoplasm,(More)
199 out of 509 foxes culled in a rabies control scheme, were shown to be infected with the metastrongylid parasite Angiostrongylus vasorum. Pathological lesions associated with angiostrongylosis in the fox are described and compared to reported lesions of A. vasorum infection in the dog. The lesions observed in the foxes seemed to be less severe and mainly(More)
Neuropathological changes have been described associated with feline immunodeficiency virus (FIV) infection. The objective of our study was to characterize the lesions found in the brain and spinal cord of experimentally FIV-infected cats and to quantify, by morphometric analysis, the intensity of gliosis found in these subjects at different time post(More)
Macroscopic and histological study of a case of unilateral hydrocephalus in a young wild European brown hare (Lepus europaeus) is reported here. Morphological changes were mostly massive dilatation of the left lateral ventricle, atrophy of the cortex and a striking reduction of the corresponding white matter. Lymphocytic cell infiltrates and(More)
