Abstract: O presente trabalho teve por objetivo estudar comparativamente as altera es clínicas e hematológicas desencadeadas por isolados de Babesia bigemina das regi es Sudeste, Nordeste e Norte do Brasil em bezerros Nelore infectados experimentalmente. Foram utilizados 18 bezerros com idade entre sete e nove meses, isentos de anticorpos contra Babesia sp. e criados livres de carrapatos. Três animais foram previamente inoculados com 2,0x10(9) eritrócitos parasitados (EP) para cada isolado. Os outros 15 bezerros foram subdivididos em três grupos de cinco animais, que foram subinoculados com 1,0x10(10) EP dos respectivos isolados. Foram avaliadas as altera es clínicas e hematológicas por meio da determina o da parasitemia, do hemograma, do fibrinogênio plasmático, da contagem de reticulócitos, da análise descritiva da medula óssea e da fragilidade osmótica eritrocitária, no decorrer de 30 dias, perfazendo um total de sete momentos de observa o. O acompanhamento da resposta imunológica pelo teste de imunofluorescência indireta foi realizado diariamente até o 10masculine dia pós-inocula o (DPI) e posteriormente no 15masculine, 20masculine, 25masculine e 30masculine DPI. Clinicamente, observou-se uma manifesta o muito branda da doen a. Os achados laboratoriais revelaram baixos níveis de parasitemia; decréscimo nos valores do eritrograma; ausência de reticulócitos; diminui o inicial na contagem total dos leucócitos, neutrófilos e linfócitos com posterior eleva o do número destas células; hipercelularidade da série eritrocítica e decréscimo da rela o mielóide:eritróide mais acentuada entre o 8masculine e 12masculine DPI e um aumento da fragilidade osmótica eritrocitária nos grupos inoculados com os isolados sudeste e nordeste. Nenhum dos três isolados de B. bigemina desencadeou a forma clínica característica da enfermidade, apesar de induzirem uma resposta imune humoral.

Abstract: Five cases of leucoencephalomalacia (LEME) in horses and one in mule are reported in the State of Pernambuco, Northeastern Brazil. All animals were fed with corn or byproducts. The disease occurred in different months of the year, in the dry or raining seasons. The animals had nervous signs and the clinical manifestation period was of 24 hours to 13 days. Gross and histologic lesions of the nervous system were malacia of the centrum semi-ovale and corona radiata in all animals, brain stem in 3, and internal capsule in one. Degenerative lesions of the liver were observed in one of a total of 4 cases in which this organ was examined histologically. This animal also had increased levels of serum AST and GGT. LEME seems to be an important disease in equidae in the Brazilian semiarid. Preventive measures include correct grain storage after proper drying and also to avoid the use of corn and byproducts as the only food for horses. KEY WORDS: Leucoencephalomalacia, horses, mules, semiarid, fumonisins. Este artigo descreve cinco casos de leucoencefalomalácia (LEME) em eqüinos e um caso em muar ocorridos no Agreste do Estado de Pernambuco. Todos os animais tinham histórico de ingest o de milho ou subprodutos. A doen a ocorreu em diferentes épocas do ano, tanto na seca quanto na chuva. Os animais apresentaram sinais nervosos e a evolu o clínica foi de 24 horas a treze dias. As les es macroscópicas e histológicas caracterizaram-se por malacia do centrum semi-ovale e corona radiata em todos os casos, tronco encefálico em três casos e cápsula interna em um caso. Les es degenerativas do fígado foram observadas em um dos quatro casos em que foi estudada a histologia desse órg o. Esse animal apresentou, também, aumento dos níveis séricos de AST e GGT. Este trabalho comprova que a LEME é uma doen a que pode ser importante em eqüídeos, na regi o Nordeste. Para a profilaxia da micotoxicose, recomenda-se o armazenamento do gr o em ambientes livres de umidade, após ser submetido a um correto processo de secagem, além de evitar a administra o de milho e subprodutos como único alimento. PALAVRAS-CHAVES: Leucoencefalomalácia, eqüinos, muares, semi-árido, fumonisinas.

Abstract: The purpose of this work was to evaluate the therapeutic method utilized in 60 cases of frothy bloat in cattle attempted in the in the Bovine Clinic, Campus Garanhuns – UFRPE, between January of 1989 and September of 2007. The data from evolution of the disease, type of therapy adopted and its clinical evolution after institution of treatment and the destination of the cases were analyzed. The evolution period of the disease was around six days. The therapy was chosen according to the clinical condition severity presented as follows: four (6.67%) were sent to slaughter, 17 (28.33%) were nonsurgically treated and from these 16 (94.11%) recovered and one (5.89%) died. The medium time for recovery with this therapeutic conduct was between three and four days. Thirty nine (65.00%) animals were treated by ruminotomy, from these 33 (84.62%) recovered, six (15.38%) died and the mean time for recovery was between nine and 10 days. Cattle suffering from frothy bloat have a good prognosis when treatment is taken in due time. KEY WORDS: Cattle, fermentative disturbance, ruminants, therapeutic. Este trabalho teve por finalidade analisar a conduta terapêutica de sessenta casos de timpanismo espumoso, em bovinos, atendidos na Clínica de Bovinos, Campus Garanhuns, da Universidade Federal Rural de Pernambuco, no período de janeiro de 1989 a setembro de 2007. Analisaram-se os dados referentes à evolu o da enfermidade, tipo de conduta terapêutica adotada e sua evolu o clínica após instituída e destino dos casos. O período de evolu o da doen a foi em torno de seis dias. A escolha da conduta terapêutica dependeu da gravidade da condi o clínica apresentada pelos animais, sendo quatro (6,67%) encaminhados ao abate, dezessete (28,33%) tratados clinicamente, sendo que, destes, dezesseis (94,11%) obtiveram alta e um (5,89%) veio a óbito. O tempo médio de recupera o, com essa conduta terapêutica, foi de três a quatro dias. Trinta e nove animais (65,00%) foram tratados por ruminotomia, sendo que, destes, 33 (84,62%) receberam alta, seis (15,38%) vieram a óbito, com tempo médio de convalescen a de nove a dez dias. Os animais acometidos com timpanismo têm um prognóstico favorável quando a conduta terapêutica é empregada a tempo. PALAVRAS-CHAVES: Bovinos, distúrbio fermentativo, ruminante, terapêutica.

Abstract: despite the frequent use of dry and fibrous roughage for feeding cows in many regions, especially during the dry season, impaction of the abomasum has been poorly reported in brazil, probably because the condition is misdiagnosed by practitioners. the present paper aimed to accomplish a retrospective study on primary abomasal impaction in 14 cattle from pernambuco state, northeastern brazil. eight moderate cases, without severe abdominal distention and with no rumen compaction, were treated conservatively, and four severe cases, with severe abdominal distention and rumen compaction, were treated surgically. one bull was slaughtered and one cow died without treatment. the greater number of abomasal impaction cases was in holstein cows with six cases (42.9%), followed by crossbred cattle with five cases (35.8%), and the breeds brown-swiss, nelore and marchigiana, each with one case (21.3%). the food composition was characterized by low quality fibers and varied greatly among cases. most frequent clinical signs were apathy, dehydration, hypomotility and ruminal bloat, intestinal hypomotility and scanty or absent feces with mucus. the hematological findings revealed leukocytosis with neutrophilia and hyperfibrinogenemia in most cases. ruminal fluid analysis showed compromised flora and fauna dynamics and increased chlorine ion concentration. clinical (4/8) and chirurgical (2/4) recovery rate achieved 50%. the clinical and chirurgical methods remain as viable options for the treatment of light and severe impaction, but the prognosis is always reserved especially when associated to late pregnancy.

Abstract: the continuous genetic selection for high milk production in association with greater digestive capacity and corporal depth increases the susceptibility for abomasopathies including abomasal displacement. the present work aimed to accomplish a retrospective study on abomasal displacement in 36 cattle attended at bovine clinic, garanhuns campus, federal rural university of pernambuco, through january 2000 to february 2009. twenty seven cases of right abomasal displacement, six cases of left abomasal displacement and three of abomasal volvulus were diagnosed. eleven moderate cases, without severe abdominal distention, appetite for roughage and metallic sound (“ping”) reaching at the most the 8th intercostal space were treated conservatively, and 20 severe cases with moderate to severe abdominal distention associated to systemic disturbances were treated surgically. two cows were euthanized due to diffuse peritonitis or severe alterations in the abomasal serosa totalizing 18 animals submitted to the surgical treatment. two animals were slaughtered and three cows arrived prostrated and died without receiving any treatment. risk factor analysis identified rainy season as statistically significant. the greater number of abomasal displacement was in crossbred cows with 24 cases (66.6%), followed by holstein and gir cattle with 11 (30.5%) and one (2.9%) cases, respectively. food composition varied greatly and characterized by excess of carbohydrates and in most cases low quality fibers. most frequent clinical signs were apathy, dehydration, light to severe ruminal bloat with reduced or absent motility, splashing sound during right flank ballottement, ping and a distended viscera-like structure in the side of the displacement; liquid, blackish and fetid feces. hematology reveals leukocytosis with neutrophilia and hyperfibrinogenemia in most cases. ruminal fluid analysis showed compromised flora and fauna dynamics and increased chloride ion concentration in 93.9% of the cases

Abstract: outbreaks of a disease of the nervous system are reported in cattle in three farms in the agreste region of the state of pernambuco. morbidity, mortality and fatality rates varied from 3 to 25%, 0 to 20% and 0 to 60%, respectively. a weed found in large amounts in the pastures was identified as solanum paniculatum. clinical signs were characterized by transitory, periodic attacks with loss of balance, incoordinated gait, neck and head extension, hypermetria, intention tremors, nystagmus, and falls. the attacks were induced when the animals were disturbed or by the application of the head raising test. two cows showed permanent signs including ataxia, abnormal posture, staggering gait with limbs in abduction, intention tremors, hypermetria, and progressive weight loss. histological lesions in one cow were fine vacuolation of the cerebellar purkinje neurons with marginalization of the nucleus. loss of purkinje neurons with proliferation of bergmann astrocytes and wallerian degeneration with axonal spheroids in the granular layer and cerebellar white matter were also observed. neuronal vacuolation and axonal spheroids were observed in the gracillis nucleus. in one cow that stayed for approximately 10 months in an area free of s. paniculatum with permanent signs, there was a severe depletion of purkinje neurons in the cerebellum. the granular and molecular layers were reduced and depleted of cells. considering that the toxic compound of s. paniculatum is unknown, and that the plant is largely used as a medical plant, it is necessary to take into account the risk of human poisoning.
