Perdas econômicas causadas por lesões nodulares características de reação vacinal contra febre aftosa em bovinos abatidos em Mato Grosso do Sul, Brasil / Econômic losses caused by carcterisitc nodular injuries of vaccine reaction against foot-and-mouth disease in cattle slaughtered in Mato Grosso do Sul, Brazil

Para avaliar a incidência e estimar as perdas econômicas decorrentes de lesões nodulares características de reação vacinal contra febre aftosa foi acompanhado o abate de 72.000 bovinos no Mato Grosso do Sul, de maio a junho de 2018. O estudo foi realizado com base na avaliação macroscópica das lesões, que resultaram em uma incidência/mês média de 99,0% no rebanho abatido. O peso médio de descarte devido ao abscesso foi de 1,56kg/carcaça e a perda estimada foi de 673.920kg/ano ou 44.928 arrobas/ano. O preço médio de venda da carne foi de R$ 11,65/kg, sendo estimada perda de R$ 7.851.168,00/ano (US$ 2.116.117,79/ano). A elevada incidência de lesões nodulares características de reação à vacina contra febre aftosa nos bovinos abatidos no Mato Grosso do Sul representa um problema sanitário e econômico relevante na cadeia da carne.(AU)

Infecção por Gurltia paralysans em gatos domésticos no Estado de Pernambuco, Brasil / Gurltia paralysans infection in domestic cats in the State of Pernambuco, Brazil

Background: The Gurltia paralysans nematode was initially described in Chile and for many years it was believed that thedisease caused by this parasite was restricted to this country. However, in Argentina, Uruguay and more recently in Brazil,among other countries, cases of Gurltiosis have been described in both domestic and wild cats. This disease is chronic anddebilitating due to the progressive paralysis developed. This study aimed to describe the clinical, epidemiological and pathological aspects of G. paralysans infection in domestic cats of the Agreste region of the state of Pernambuco, Northeast Brazil.Case: Clinical, epidemiological and pathological aspects of G. paralysans infection in domestic cats in the rural area oftwo Agreste municipalities in the state of Pernambuco, Brazil, are described. Seven farms were visited, in which 11 maleand female affected felines were evaluated. Among these, euthanasia was performed in four cases, at the owners requestand due to the advanced stage of the disease. Clinical signs began with ataxia of the pelvic limbs and evolved to jumpingdifficulty, lateral falls, muscle atrophy, pelvic limb scarring, and paralysis at the most severe stage of the disease, whichdeveloped in a one-year period, approximately. According to the owners, the affected cats died between six months andone year after the initial clinical signs. At necropsy, there were segments of the spinal cord with extensive reddish areasin the dura, between T7 and S2, corresponding to varices. These were characterized by numerous congestive, dilatedand tortuous blood vessels observed in the dorsal plane, but more pronounced in the ventral plane of the meninges. Inthe bladder, multifocal areas of hemorrhage were observed. Histologically, vascular lesions in veins and venules of theleptomeninges were characterized by venous varices with thrombosis, fibrosis and intravascular parasites associated withmoderate...(AU)

Isolation and identification of Mycobacterium bovis in cattle slaughtered from an abattoir in Garanhuns, Pernambuco / Isolamento e identificação de Mycobacterium bovis em bovinos abatidos em matadouro público de Garanhuns, Pernambunco

Tuberculosis is a chronic infectious disease caused by the Mycobacterium tuberculosis complex (CMT), members including M. bovis. The sanitary inspection in slaughterhouses has a great importance on public health for the removal of contaminated meat with pathological lesions. Cattle slaughtered in the abattoir of Garanhuns were subjected to macroscopic, histological, bacteriological, and molecular analyses. Lung inspection revealed gross lesions suggestive of tuberculosis. The characterization of tuberculous granulomas was performed by histopathology and hematoxylin and eosin (HE) staining. The identification of acid-fast bacilli (AFB) was performed on smears with fresh material and histological staining using Ziehl-Neelsen stain. Bacteriological diagnosis was carried out using Stonebrink and Lowenstein-Jensen media, and polymerase chain reaction (PCR) was performed from the DNA extracted from colonies for the identification of Mycobacterium spp. We found that 1% (32/3,.180) of the collected lungs showed lesions suggestive of tuberculosis. Histopathological analysis revealed that 65.62% (21/32) samples had granulomatous pneumonia. AFB was detected in 46.88% (15/32) smears and 4.16% (1/24) histological sections, as analyzed by Ziehl-Neelsen staining. Moreover, 68.75% (22/32) samples showed bacterial growth and molecular identification 90% (18/20) of the samples were positive...
