Molossi,Franciéli Adriane; Pont,Tainah Pereira Dal; Echenique,Joana Vargas Zillig; Almeida,Bruno Albuquerque de; Lopes,Bruna CorreaABSTRACT: Respiratory problems due to tracheobronchial foreign bodies (FBs) are unusual in horses; although equines kept in pastures eventually inhale FBs, as conifer twigs of Araucaria angustifolia. A 1,5-year-old Criolle foal was presented with hemoptysis, dyspnea, restlessness and fever (40.9 ºC rectal temperature). Complete blood count showed intense neutropenia, monocytosis, thrombocytopenia and hypoprotei...
Pulmonary choristoma in a new-born calf with multiple cranial and nervous malfo...
Wronski,Júlia Gabriela; Argenta,Fernando Froner; Kemper,Regina Tose; Raiter,Jacqueline; Oliveira,Natasha Rossoni de; Driemeier,DavidABSTRACT: Multiple congenital malformations can occur concomitantly in several species since the anomaly in one organ may lead directly to the malformation of another. Additionally, the etiology is not always clarified. Choristoma refers to an ectopic tissue that is histologically normal in an abnormal location. A case of pulmonary and nodal choristoma associated with cranioschisis, hydrocephalus, and syringomy...
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...

Molossi,Franciéli Adriane; Cecco,Bianca Santana de; Henker,Luan Cleber; Vargas,Thainã Piccolo; Lorenzett,Marina Paula; Bianchi,Matheus ViezzerABSTRACT: Salmonellosis is a bacterial disease that affects several domestic animal species, and is commonly diagnosed in cattle, horses, and pigs. This study aimed to describe the epidemiological and pathological findings of eleven cases of enteric salmonellosis and two cases of salmonellosis with pulmonary involvement in cattle in Rio Grande do Sul State, Brazil. Clinical signs included fever, yellow diarrhea...

Santos,Igor Ribeiro dos; Henker,Luan Cleber; Pont,Tainah Pereira Dal; Panziera,Welden; Pavarini,Saulo Petinatti; Melo,Marília Martins; Driemeier,DavidABSTRACT: Forty 1-2-y-old water buffaloes were simultaneously treated with trichlorfon and chlorpyrifos products in the recommended dose for cattle. After a week, 19 animals started presenting clinical signs characterized by apathy, diarrhea, aggressiveness, dehydration, and motor incoordination, followed by flaccid paralysis and permanent lateral recumbency. All affected buffaloes died after a clinical course ...
Tuberculosis outbreak in intensive swine farming from southern Brazil
Lopes,Bruna Correa; Vidaletti,Marina Roth; Soares,Daniel Holanda; Argenta,Fernando Froner; Mello,Lauren Santos de; Pavarini,Saulo PetinattiABSTRACT: Mycobacterium tuberculosis var. bovis is the etiologic agent of animal tuberculosis (aTB), a neglected zoonotic disease. Animal tuberculosis can affect many species, including swine. aTB-consistent granulomas in these animals lead to carcass disposal, generating economic losses and posing risks to human health. In the present study, an aTB outbreak was identified at an intensive swine farming operatio...
Major cardiac defects in cattle in southern Brazil: retrospective study of necr...
Wronski,Júlia Gabriela; Cecco,Bianca Santana de; Lorenzett,Marina Paula; Driemeier,David; Pavarini,Saulo Petinatti; Sonne,LucianaABSTRACT: Cardiac malformations are reported to be relatively rare in bovine species, with ventricular septal defects being the most common abnormality observed predominantly in young calves. This report aims to describe the cardiac malformations observed in bovids and review the literature related to those malformations in this species. The necropsy reports of 1,783 bovids were reviewed, and 0.4% were diagnose...
Agents of pneumonia in slaughtered pigs in southern Brazil
Conti,Elisa R. De; Takeuti,Karine L.; Schwertz,Claiton I.; Bianchi,Ronaldo M.; Driemeier,David; Barcellos,David E.S.N. deABSTRACT: A high prevalence of pneumonic lesions has been reported to affect slaughtered pigs in southern Brazil. In order to identify which microorganisms have been causing those lesions, 30 pig lungs presenting pneumonic gross lesions were collected from five different slaughterhouses, totaling 150 lungs. Samples for bacterial isolation, molecular, histopathologic and immunohistochemistry (IHC) evaluation wer...
