Equine abortion associated with placentitis caused by Pasteurella pneumotropica
Juffo,Gregory D.; Antoniassi,Nadia A.B.; Bassuino,Daniele M.; Gomes,Danilo C.; Snel,Gustavo G.M.; Pavarini,Saulo P.; Driemeier,DavidABSTRACT: Pasteurella pneumotropica is a bacterium that has so far not been described as a cause of placentitis in animals. Two cases of aborted equine fetuses were sent to the Department of Veterinary Pathology of the “Universidade Federal do Rio Grande do Sul” (SPV-UFRGS) for anatomopathological examination. Both cases presented suppurative placentitis associated with multiple basophilic bacterial cells. Afte...
Spontaneous poisoning by Cestrum intermedium in dairy cattle
Pohl,Camila B.; Hammerschmitt,Márcia E.; Molossi,Franciéli A.; Lorenzett,Marina P.; Bianchi,Ronaldo M.; Vignoli-Silva,Márcia; Bianchetti,SamuelABSTRACT: Acute hepatotoxicity caused by plants poisoning is responsible for economic losses in farm animals in Brazil. Reports of Cestrum intermedium natural poisoning in cattle are not commonly described in Rio Grande do Sul (RS). This study aimed to document an outbreak of spontaneous C. intermedium poisoning in dairy cattle in the Central-Eastern Mesoregion of RS. Three nine-month-old Holstein and Jersey he...
Causes of death in sheep in Rio Grande do Sul, Brazil: analysis of 523 cases (2...
Cecco,Bianca S.; Molossi,Franciéli A.; Henker,Luan C.; Lorenzett,Marina P.; Correa,Gabriel L.F.; Driemeier,David; Pavarini,Saulo P.; Sonne,LucianaABSTRACT: The increase in the commercialization of sheep products requires an equivalent improvement in flock health and rapid disease identification. Data regarding the cause of death in sheep were reviewed from the database of the “Setor de Patologia Veterinária” from the “Universidade Federal do Rio Grande do Sul”, from January 2004 and December 2019. Epidemiological features, such as breed, sex, and age, in...
Diseases of the central nervous system in swine in Southern Brazil
Hammerschmitt,Márcia E.; Almeida,Bruno A.; Pereira,Paula R.; Pavarini,Saulo P.; Sonne,Luciana; Driemeier,DavidABSTRACT: Brazil is the fourth largest exporter of pork worldwide, with its production concentrated in the Southern region of the country. To reduce the economic impacts and increase herd health, an efficient diagnosis of diseases is necessary. The frequency, seasonal, and annual distribution of diseases that affecting the swine nervous system in Southern Brazil were determined through a retrospective study con...
Acute necrotic hepatotoxicity caused by Lantana camara L. ingestion in dairy ca...
Silva,Emanoelly M.S.; Rosa,Rafael B.; Molossi,Franciéli A.; Ribeiro,Paula R.; Almeida,Kevin G.S.; Pinheiro,Gabriely F.; Dalto,André G.C.ABSTRACT: This study describes an outbreak of acute necrotic hepatopathy associated with spontaneous poisoning by Lantana camara L. in dairy cattle. A herd of 15 cows and heifers was introduced into a native pasture with limited food supply, and, sixteen days later, eight animals had spontaneous nasal hemorrhage, fever, lethargy, jaundice, and dry, dark stools with mucus and blood. The clinical course varied fr...
Causes of death of sows in three Brazilian pig farms
Schwertz,Claiton I.; Bianchi,Ronaldo Michel; Cecco,Bianca S.; Pavarini,Saulo P.; Driemeier,DavidABSTRACT: Sow mortality is directly related to financial losses and productive efficiency in pig farms. Despite this, diseases associated with the death of sows are poorly understood. This study aimed to determine the main causes of death of sows in Brazilian pig farms. To perform this research, three Brazilian pig farms were visited, and necropsies were performed on all sows that had died spontaneously or were...
Pathological and immunohistochemical aspects of primary hepatobiliary neoplasms...
Argenta,Fernando F.; Mello,Lauren S.; Caprioli,Rafaela A.; Pavarini,Saulo P.; Driemeier,David; Sonne,LucianaABSTRACT: Primary hepatobiliary neoplasms (PHN) are uncommon in cats, and originate in hepatocytes, intra- and extrahepatic bile ducts, mesenchymal cells, and cells of neuroendocrine origin. The aim of this study was to determine the frequency of PHN in cats diagnosed in the metropolitan region of Porto Alegre (RS), Brazil, for a period of 17 years, determining their epidemiological, anatomopathological and imm...
Primary nonlymphoid gastrointestinal neoplasms in dogs in Rio Grande do Sul
Slaviero,Mônica; Argenta,Fernando F.; Ehlers,Luiza P.; Lorenzo,Cíntia De; Pavarini,Saulo P.; Driemeier,David; Sonne,LucianaABSTRACT: Gastrointestinal neoplasms (GIN) are uncommon in dogs, but they mainly show malignant behavior and poor prognosis. The types of GIN in dogs and their frequency, as well as their epidemiological and histopathological characteristics were analyzed through a retrospective study of biopsies from 24.711 dogs from 2005 to 2017. Additionally, histological sections of neoplasms were subjected to immunohistoch...
Epidemiological and pathological aspects of noninfectious diseases of the gastr...
Bianchi,Matheus V.; Ribeiro,Paula R.; Stolf,Alanna S.; Bertolini,Marianna; Laisse,Cláudio J.M.; Sonne,Luciana; Driemeier,David; Pavarini,Saulo P.ABSTRACT: Equine colic is one of the most common cause of death in horses, but few studies have investigated specifically the conditions at the necropsy. This study aimed to describe the epidemiological and pathological features of noninfectious diseases of the gastrointestinal tract in horses. A retrospective study was conducted in search of cases of these diseases affecting horses from 2005 to 2017. During th...

Konradt,Guilherme; Bassuino,Daniele M.; Siqueira,Lucas C.; Bianchi,Matheus V.; Sonne,Luciana; Driemeier,David; Pavarini,Saulo P.ABSTRACT: This study aimed to determine the frequency and distribution of infectious diseases diagnosed through necropsy examination and histopathological analysis in growing/finishing pigs along 12 years (2005-2016) in Southern Brazil. We evaluated 1906 anatomopathological exams of pigs at growing/finishing phases, of which the infectious diseases corresponded to 75.6% of the cases (1,441/1,906). Porcine circo...
