ABSTRACT: The aim of the present study was to describe an outbreak of atypical interstitial pneumonia affecting 15 Angus cattle aged 7-30 months in the south of Rio Grande do Sul. The clinical course of the disease was approximately 1-3 days. The cattle were kept in the native field and had received feed containing the remains of wafers from a food factory before the outbreak. Clinical signs included dyspnea and abdominal breathing, with a clinical evolution period of up to 3 days. Nine animals presented apathy and respiratory difficulty and died within 24h, while three animals exhibited a clinical evolution period of 36-48h. Three other animals died without any clinical signs. The main macroscopic lesions were observed in the lungs, which did not collapse...

Provedor de dados: 65
Autores: Ruas,Jerônimo Lopes; Schild,Ana Lucia; Fernandes,Cristina Gevehr; Ferreira,João Luiz Montiel; Müller,Gertrud.
Equine cerebral hydatid disease is described in a 7-year-old, crossbred, female horse. Clinical signs were characterized by circling gait, pressing of head against fences or objects and motor incoordination. On gross examination of the brain the hemispheres were swollen, mainly the left one. On transversal sections, a 5cm X 7cm fluid-filled cyst was observed within the lateral ventricle of the left hemisphere. The cyst extended from the parietal to the occipital lobe, and compressed the third ventricle. There was also marked mid line deviation. Histologically, the brain lesion adjacent to the cyst, was characterized by a piogranulomatous process and vacuolization of neuropil. A diagnosis of equine hydatidosis caused by Echinococcus granulosus was made on...

Autores: Vargas Junior,Sérgio Farias; Marcolongo-Pereira,Clairton; Halinski-Silveira,Dênis; Grecco,Fabiane Borelli; Raffi,Margarida Buss; Schild,Ana Lucia; Sallis,Eliza Simone Viégas.
This study describes the natural poisoning of goats by Rhododendron simsii in Southern Brazil. Five of eight goats died after ingesting branches of plants, which were pruned and placed near the goats. Clinical signs observed were restlessness, shrill bleating, profuse regurgitation, looking and kicking at the flank, a loss of balance, irregular gait, staggering, and opisthotonos. At necropsy or histopathology affected goats had not showed lesions. Two goats were fed with 21.5g kg-1 bw and 30g kg-1 bw of fresh leaves of R. simsii. Both goats developed signs similar to those naturally affected goats. These findings indicated that R. simsii is highly toxic and lethal to goats.

ABSTRACT: A case of lissencephaly-pachygyria and cerebellar hypoplasia diagnosed in a Charolais x Tabapuã calf is described. The calf presented since birth, clinical signs characterized by apathy, prolonged recumbency, tremors of the head and neck, ataxia, hypermetria, difficulty walking, blindness and swelling of the joints of the four limbs. Due to the unfavorable prognosis, the animal was euthanized and necropsied at 34 days of age. At necropsy, a rudimentary development of the brain folds (gyri) and grooves (sulci) was observed, and the cerebellum was hypoplastic. The cut surface of the brain exhibited thickening of the gray matter (pachygyria) in the frontal, parietal, temporal and occipital cortices and narrowing of the white matter. In the organs of...

Provedor de dados: 65
Autores: Echenique,Joanna Vargas Zillig; Estima-Silva,Pablo; Pereira,Daniela Brayer; Marques,Lucas Santos; Ribeiro,Luiza Soares; Schild,Ana Lucia.
ABSTRACT:  Horse leukoencephalomalacia (ELEM) is a disease caused by the ingestion of mycotoxins (fumonisins) produced by fungi of the genus Fusarium that infect corn and/or its byproducts. This disease has been described by ingestion of mature corn with humidity above 15% at temperatures below 20°C. The aim of this paper was to report an outbreak of leukoencephalomalacia in horses fed with immature corn. Two horses out of three showed neurological signs approximately seven days after eating immature corn in its reproductive phase (R2, milky grains). Corn was harvested and administered directly to the animals, with no storage. Deaths occurred approximately 24 hours after the onset of clinical signs. Grossly, there were multifocal dark red to brown areas in...

ABSTRACT: The purpose of this paper was to describe obstructive urolithiasis with uroperitoneum and hydronephrosis in range cattle in southern Rio Grande do Sul. The disease was observed in castrated male cattle, aged between 18 months and 3 years in a herd of 200 steers that were in a ryegrass pasture during the winter and a native pasture during the summer. Different mineral salts were used as a supplement for the animals during the two seasons of the year. Cattle presented a progressive abdominal distention, depression and dehydration ranging from 10 days to one month in duration. One animal was necropsied, and approximately 50 liters of urine (uroperitoneum) in the abdominal cavity were observed. The bladder had a small rupture and was adhered to the...

Provedor de dados: 65
Autores: Marcolongo-Pereira,Clairton; Stigger,Adriana; Fiss,Letícia; Coelho,Ana Carolina; Santos,Bianca; Junior,Sergio Vargas; Schild,Ana Lucia.
This report describes pneumomediastinum and subcutaneous emphysema in a bull with paralytic rabies. The bull displayed severe swelling in the head, neck, chest and forelimbs extending to the ventrum, including the prepuce, 7 days after the development of neurological signs. At necropsy, extensive subcutaneous emphysema was observed in the neck region, abdominal wall and proximal forelimbs. The lungs failed to collapse and had severe emphysema with bullae. Rabies was suspected due to an ongoing outbreak at the farm and was confirmed by histologic lesions and immunohistochemistry. Similar to humans, pneumomediastinum and subcutaneous emphysema should be considered as an unusual complication of rabies in cattle.

Provedor de dados: 65
Autores: Almeida,Milton Begeres de; Schild,Ana Lucia; Pfister,James; Pimentel,Marcelo; Forster,Karine Maciel; Correa,Franklin Riet.
Three experiments were performed to determine the efficacy of various methods of averting naïve cattle to prevent Baccharis coridifolia poisoning: forced oral administration of 0.5g kg-1 body weight of fresh B. coridifolia; forced inhalation of the smoke from burning B. coridifolia and rubbing the plant on the animals' muzzles and mouths; and introducing the animals into paddocks with low invasion by B. coridifolia. Results demonstrated that cattle forced to ingest low doses become strongly averted if introduced into paddocks 23-26 hours after the aversion. In contrast, cattle introduced into the paddocks between 1-10 hours were not fully averted. Inhalation of B. coridifolia smoke, and rubbing the plant on the animals' muzzles and mouths were not...
