Item Listeriose em ruminantes e sua importância como zoonose(2017-01-04) Souza, Leonardo Magno de; Souto, Rodolfo José Cavalcanti; http://lattes.cnpq.br/4263478911176230; http://lattes.cnpq.br/9374224266583090Listeriosis is an infectious disease caused by Gram-positive bacteria. This bacteria, called Listeria monocytogenes, is a facultative intracellular microorganism that has a predilection for causing infections of the central nervous system (CNS) in humans and domestic animals. In addition, it also may affect several animal species, inducing various forms of clinical manifestation, including septicemia of neonates with abscesses in viscera such as liver and spleen, abortion, neonatal death, ophthalmitis, and neurological disease as meningoencephalitis. Moreover, only one clinical form has seen in previous outbreaks. Several factors favor bacterial growth as poor quality silage (pH above 5.5) favors; other sources of infection include contaminated soil and food, and feces or milk from carried animal. In Brazil, no previous outbreaks involving L. monocytogenes have reported in humans; however some authors have conducted several researches on food and equipment involved in the manufacturing process. In a healthy population, consumption of contaminated food with L. monocytogenes usually causes a self-limiting gastroenteritis, fever, nausea, vomit, and diarrhea. Patients develop clinical signs within a few days of exposure to contaminated food. Several outbreaks involving various types of food have been described around the world. In some cases of gastroenteritis may lead to the invasive form of listeriosis in humans. Thus, it was the target of several studies as one of the major foodborne diseases for humans, causing several outbreaks around the world. This agent has a predilection for CNS tissue of humans and animals. Therefore, the purpose of this work is to clarify the interrelationship between Listeriosis as zoonosis and ruminant disease.Item Principais plantas tóxicas em pastagens do Nordeste, com ênfase em Pernambuco(2019) Ferreira, Claudia Maciel; Cunha, Márcio Vieira da; http://lattes.cnpq.br/8936474723708253; http://lattes.cnpq.br/4541443783709386The number of plants described as toxic grows more and more. There are currently approximately 130 plant species considered toxic. The presence of toxic plants in production systems can generate losses and know which plants are, morphological characteristics, toxic principles, toxic dose, toxicity level, animals that are affected, as well as preventive actions, are of utmost importance for livestock. To be considered toxic the plant needs to be tested through laboratory experiments and with the animal species in question, as there are many differences in effects caused by plants between animal species. And plants considered toxic, experimentally need to cause some kind of pathology when ingested by animals and occur in natural conditions, so they are considered toxic plants of livestock interest. Objective of this work was to perform a literature review on the main toxic plants of the Northeast, with those occurring in the state in Pernambuco. Toxic plants affect animals in a number of ways, such as gastrointestinal disturbances, central nervous system problems, reproductive system problems, and photosensitization and sudden death. Toxic plants that occur on pastures can cause many losses, including animal death. Knowing these plants is strategic for proper pasture management. The best way to control the occurrence of these plants is to properly manage pastures, with stocking adjustment based on forage mass and definition of grazing frequency based on pasture growth.
