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)
Spontaneous tumors in dog have been demonstrated to share many features with their human counterparts, including relevant molecular targets, histological appearance, genetics, biological behavior and response to conventional treatments. Mammary tumors in dog therefore provide an attractive alternative to more classical mouse models, such as transgenics or(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 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)
Renal tissues from 15 cats naturally infected with feline immunodeficiency virus (FIV) were examined histologically, immunohistochemically and ultrastructurally. Renal function and urinary proteins were also studied. Kidney abnormalities were found in 12 cats and were characterized by mesangial widening with segmental to diffuse glomerulosclerosis and(More)
Renal alterations characterized morphologically by glomerular and tubulo-interstitial lesions and clinically by a heavy proteinuria and sometimes by renal failure are frequent in feline immunodeficiency virus (FIV) infected cats. To investigate the possible role of local FIV replication in the genesis of this renal damage, renal tissues of 15 consecutive(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)
Two hundred and seventy-seven sick pet cats living in Italy were tested for antibodies to feline immunodeficiency virus (FIV) and for feline leukemia virus (FeLV) antigen. Overall, 24% of the cats resulted positive for anti-FIV antibody and 18% for FeLV antigen. FIV was isolated from the peripheral mononuclear blood cells of ten out of 15 seropositive cats(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)
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)
