Dioctofimatosis is a disease caused by the nematode Dioctophyme renale, which occurs mostly in dogs and has predilection mostly for the right kidney and when penetrating the renal capsule, it causes destruction and atrophy of the renal parenchyma, and only one fibrous capsule of the affected kidney may remain. Thus, seeking to establish the histological conditions of the contralateral kidney (RCL) of the affect...
Squamous cell carcinoma (SCCs) is a malignant epithelial tumor of keratinocytes, composed of heterogeneous cells with varied phenotypes, which occurs mainly in glabrous regions, with little or no pigmentation. It is a common neoplasm in dogs, cats, horses and cattle, relatively uncommon in sheep and rare in goats and pigs. This study aimed to carry out a critical review of the different histopathological classi...
Aspergillosis is a respiratory fungal disease of importance in captive marine birds. The aim of this study was to describe the occurrence of aspergillosis in Thalassarche melanophris during rehabilitation events and to identify the etiological agent. All the albatrosses that were received for rehabilitation and died within a 2-year period were included in the study. The proportionate mortality rate caused by as...
Due to the difficulty in the access to free-ranging birds, data regarding Aspergillus infections in wild avian species is rare compared to captive wild and domestic birds. Objective: report three cases of Aspergillus section Fumigati causing fungal disease in free-ranging aquatic birds, with the identification of the causal agent to the species level. Case reports: The diagnosis of aspergillosis was performed b...

Mammary neoplasms are described as the third most common type of feline tumor, after haematopoietic and skin tumors, and present a challenge for clinicians because the prognosis for feline mammary tumors ranges from guarded to poor. Thus, it is necessary to define new therapeutic approaches and establish more in-depth knowledge about this disease in felines. The main aspects of the diagnosis, prognosis and trea...

Squamous cell carcinoma is a malignant tumour of keratinocytes. There are several factors associated with the development of squamous cell carcinoma, including prolonged exposure to ultraviolet light, lack of a pigmented skin, lack of hair or a very sparse hair coat at the affected sites. A retrospective study of squamous cell carcinoma from 1978 to 2002 in farm animals was made. The samples were obtained at th...
