The specificity and immunoglobulin isotype distribution of antiphospholipid (aPL) antibodies have been evaluated in 68 patients with systemic lupus erythematosus (SLE) by ELISA which employed a panel 7 different PL antigens. A total 49 (72%) were positive for aPL isotypes directed to one or more epitopes. Prevalence IgG anticardiolipin (aCL, 37%) was similar that the other negatively charged PLs phosphatidylserine (PS, 35%), phosphatidylinositol (PI, phosphatidylglycerol (PG, 35%)...
A dioctofimose é uma afecção pouco comum em cães, causada pelo Dioctophyma renale, que ocorre com maior frequência animais errantes. Quando um único rim parasitado, os pacientes podem não apresentar sinais clínicos devido à compensação contralateral. Não havendo terapia clínica efetiva para a dioctofimose, o tratamento indicado nefrotomia ou nefrectomia, na dependência da gravidade lesão. Foi atendido no Hospital Veterinário Universidade de Passo Fundo (UPF) canino, fêmea, castrado, sem raça...
Studies have highlighted melanoma immunogenicity, and the prognostic importance of tumor infiltrating lymphocytes (TILs) mechanisms immune evasion, such as hyperexpression programmed cell death ligand 1 (PDL-1). High endothelial venules (HEV) are specialized blood vessels that can facilitate migration to tumor. Here we evaluate association HEV density PDL-1 expression in primary cutaneous melanomas with presence degree TILs other clinicopathological variables (age, sex, location,...
Histoplasmosis is a systemic disease caused by the fungus Histoplasma capsulatum. The microorganism causes localized granulomatous disease, with respiratory tract being most affected, and can spread through lymphatic blood stream. Severe infection in dogs associated immunosuppressive therapies. reported case occurred canine, brought to care serious clinical condition, which did not respond treatment was euthanized. necropsy examination showed white nodules, of firm consistency distributed...
Here we describe an outbreak of chorioptic mange in cattle, 56 years after its first identification Brazil. Between the months June and July 2011, dermatitis characterized by alopecia crusted thickened skin at insertion tail ischiorectal fossa was recognized 40 (35.7%) out 112 Holstein cows on a farm northeastern mesoregion state Rio Grande do Sul, After diagnosing caused Chorioptes bovis, were weighed treated with 0.5% ivermectin, as pour-on single dose, separated into two groups: early...
Parasitic myelopathy caused by Gurltia paralysans in domestic cats is a disease commonly reported several South American countries. The adult parasite lodged the meningeal veins and spinal cord, often causing clinical manifestations of vascular proliferation, thrombophlebitis, medullary compression. Wild felines are believed to be definitive hosts this parasite. infection occurs through ingestion paratenic hosts, but life cycle G. not yet clearly understood. In paper, we discuss case...
Toxoplasmosis, a disease caused by the intracellular coccidian Toxoplasma gondii that infects most warm-blooded vertebrates, is widely distributed and fatal for primates, which are peculiarly susceptible unknown reason(s). Owing to increasing number of Neotropical mammal deaths where in T. were detected analyzed tissues, present immunohistochemical study distribution patterns immunostainings related this parasite on primates necropsied at Laboratório de Patologia Animal Universidade Passo...
Abstract A 4-year-old female captive-bred snake of the genus Bothrops showed swelling on left side oral cavity, suggesting development neoplasia. The mass was removed surgically and sent for pathological examination. Two months later a new increase in volume same site observed, recurrence. lesion completely analysis. Histologically, two-samples consisted with highly-cell density composed spindle-shaped anaplastic cells arranged interwoven bundles, distributed throughout tissue extension and,...
Cattle tick fever (CTF) causes significant economic losses in the livestock sector. The pathogenic action of hemoparasites is associated with anemia, weight loss, abortion and reduced productivity, which result animal death. Programs to prevent CTF involve several procedures, including immunization, chemoprophylaxis use ectoparasiticides, together vector control environment. objective this study was report an acute outbreak a group 157 Hereford cattle from farm without presence vector, that...
O objetivo deste trabalho foi avaliar a ação imunoesterilizadora de uma vacina anti-hormônio liberador hormônio luteinizante (LHRH), composta por ovalbumina-LHRH-7 e tiorredoxina-LHRH-7, em touros mestiços Nelore. Vinte seis touros, com dois anos idade, foram distribuídos aleatoriamente grupos 13 animais. No grupo I, os animais receberam dose reforços da nos dias 0, 141, 287 do experimento. II, não nenhum tratamento (controle). Para o efeito realizada mensuração circunferência escrotal no...
São descritos aspectos epidemiológicos e patológicos de 19 surtos fotossensibilização observados em bovinos na região sul do Rio Grande Sul, no período entre 1984 1997.

Background: Leptospirosis is considered the most widespread zoonosis worldwide, occurring more frequently in tropical and developing regions. The aim of present study was to detect presence Leptospira spp. different primate tissues, using immunohistochemical (IHC) assays, taking advantage considerable number necropsies compatible with a diagnosis leptospirosis neotropical primates at Animal Pathology Laboratory (APL) University Passo Fundo (UPF) northern region Rio Grande do Sul.Materials,...
Tegumentary mycobacteriosis in cats is not very common. Three manifestations of skin disease associated with mycobacteria are recognized domestic cats: feline leprosy, cutaneous tuberculosis and atypical mycobacteriosis. This study aims to describe a case pyogranulomatous panniculitis Mycobacterium spp., diagnosed through histopathology histochemistry. The occurred feline, three years old, five kg, male, mixed breed, which, the clinical-physical exam, presented multiple subcutaneous nodules...
The use of anticoccidial compounds is the primary strategy for controlling avian coccidiosis. emergence drug resistance, regulatory restrictions, and societal demands meat production without antimicrobials have increased need natural alternatives to control this disease. Propolis known its antimicrobial effects may be an alternative. In context, study aimed evaluate activity jataí bee (Tetragonisca angustula) propolis against sporulation Eimeria spp. oocysts in broiler chicken feces....
