Bronchopneumonia by Streptococcus equi subsp. zooepidemicus in a horse with inh...
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...

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.

Congestive heart failure in a young cat with excessive moderator bands (false t...
Cony,Fernanda Genro; Bianchi,Matheus Viezzer; Argenta,Fernando Froner; Oliveira,Carolina Rodrigues; Stefanello,Carine; Pavarini,Saulo PetinattiABSTRACT: Left ventricular false tendons are fibrous or fibromuscular bands that transverse the ventricular cavity and have no attachment to the mitral valve in many species. In cats it is considered a congenital defect that is rarely related to clinical disease and death in adult cats. A 45 days-old mixed breed cat had a history of inappetence since birth. At the physical exam the patient was lethargic and pre...
Outbreak of organophosphorus compound-induced delayed neurotoxicity in water bu...

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...
Tarsal villonodular tenosynovitis (giant cell tumor of tendon sheath) in a dog
Daoualibi,Yasmin; Pohl,Camila Blanco; Kemper,Regina Tose; Rolemberg,Kahena Morais; Demeulemeester,Stéphanie Christine; Bandinelli,Marcele BettimABSTRACT: A 12-year-old female mixed-breed dog presented with lameness, pain, and an enlarged, non-ulcerated, nodular mass in the region proximal to the tarsal joint of the right pelvic limb. Surgical excision was performed, revealing a 6.5 cm mass adherent to the deep flexor tendon and adjacent tissues. The cut section had cysts filled with blackened clotted material, which exuded reddish serous fluid. Microsc...
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...
Fatal systemic Mortierella wolfii infection in a neonatal calf in southern Brazil
Bianchi,Ronaldo Michel; Vielmo,Andréia; Schwertz,Claiton Ismael; Cabreira,Adan; Rocha,Jéssica Goulart da; Siqueira,Franciele MaboniABSTRACT: This study described the pathological and microbiological aspects of a fatal systemic Mortierella wolfii infection in a neonatal calf in southern Brazil. The calf was born clinically normal, but on the third day of life it presented apathy, unilateral hypopyon, and neurological signs, and in the next day it was euthanized. At necropsy, multiple soft, and white-yellow nodules were observed in the liver...
