O objetivo do trabalho é descrever uma estratégia para a obtenção de animais negativos para o PCV2 oriundos de uma granja positiva para este vírus. Dezesseis leitões foram obtidos de fêmeas que tiveram os títulos de IgG anti-PCV2 e o DNA viral testados durante a gestação. Esses leitões, aos sete e dez dias de idade, foram transferidos para a unidade de pesquisa. Durante o período de 7 e 10 aos 49 e 52 dias de idade, amostras de soro, suabes nasal e fecal foram coletadas, a cada sete dias. Após esse período, três animais permaneceram na unidade de pesquisa e foram acompanhados dos 49 aos 114 dias de idade, com coletas realizadas a cada 28 dias. Não houve diferença significativa (p = 0,317) de viremia entre marrãs (n = 6) e porcas (n = 10). Com relação aos níveis de IgG, observou-se diferença significativa (p = 0,0213) entre porcas e marrãs. Os leitões (n = 16), obtidos de duas fêmeas, foram transferidos para a unidade de pesquisa. Os animais entre 7 e 10 dias e aos 49 e 52 dias de idade apresentaram queda de IgG e ausência de IgM anti-PCV2; e as amostras de soro, suabe nasal e fecal foram negativos para o DNA de PCV2. Após os 49 dias, nos três animais mantidos isolados, a detecção de IgG, IgM e DNA para PCV2 permaneceu negativa. Concluindo, a estratégia de manejo utilizada permitiu obter suínos negativos para PCV2 oriundo de granjas positivas para o agente.

This survey was conducted with the objective of developing and adapting diagnostic techniques in neurology for non-human primates, of the species Alouatta guariba Geoffroy Saint-Hilaire, 1812 (howler monkey) healthy and kept in captivity. Physical-chemical analyses were carried out in cerebrospinal fluid and its pressure measurement in the cisterna magna. Eight animals were used for the analysis of cerebrospinal fluid. In all procedures, were used chemical restraint and anesthesia with ketamine, xylazine and association of midazolam and inhalational anesthesia with isoflurane for carrying out the spinal tap. The cerebrospinal fluid analysis showed average values: protein: 16.92±9.84; glucose: 131.25mg/dL±106.7; pH: 8.37±0.69; nucleated cells: 0.5/mm³±0.75; red blood cells: 49.37/mm³±111.76 and CSF cisternal pressure: 7.37cm H2O±1.77. This study demonstrated the safety and efficacy of cerebrospinal fluid collection in the cisterna magna of Alouatta guariba, and the reference values for the specie.

Newcastle disease, salmonellosis and mycoplamosis are the most important infectious diseases in poultry. Toxoplamosis is a common disease in urban environment. The present study investigated serologic evidence of these diseases in captive and wildlife birds, with rapid plate agglutination test, haemagglutination inhibition test, and modified agglutination test. In a total of 117 blood serum samples, 20 showed the presence of Toxoplasma gondii, Mycoplasma gallisepticum, and Salmonella spp. antibodies. Amazona aestiva was the specie with the highest number of positive individuals (13/20). We also verified the first detection of T. gondii antibodies in birds of prey from Mivalgo chimachima and Rupornis magnirostris species.

Studies related cryptosporidiosis will be essential, due to its relevance in public health and pathogenicity in pets and production animals. Over the past 20 years, there has been a rapid expansion of research involving the Cryptosporidium genus, largely related to molecular studies, providing a description of various species, genotypes and subtypes of the parasite. The molecular characterization of isolates from different sources (human, animal and environmental) has been widely used in order to investigate the potential zoonotic of this protozoa. The documented transmission forms from animals to humans, from person to person, through water intake or water for the leisure that are directly or indirectly contaminated with sporulated oocysts. The high rate of animals naturally infected and the susceptibility by protozoan, justify the importance of attending to the occurrence of this disease. So are demonstrated epidemiological aspects of this zoonotic disease in domestic animals.

Toxoplasmosis, a zoonosis of worldwide distribution, has importance in human and veterinary medicine. Animals can be direct or indirect source of infection to man, and this intermediate host, the disease may be responsible for encephalitis and deaths due to congenital form as coinfection in neonates and patients with acquired immunodeficiency syndrome. The man and animals can acquire the disease by eating undercooked meat or cures, infected with tissue cysts, as well as food and water contaminated with oocysts. Iatrogenic, such as, blood transfusion and organ transplantation are other less frequent routes of transmission. The causative agent of this disease is Toxoplasma gondii, a protozoan obligate intracellular coccidian. In small animals, the infection has been reported in several countries, promoting varied clinical manifestations and uncommon but severe and fatal, which is a challenge in the clinical diagnosis of small animals, especially when the nervous system involvement. Thus, constitute the purpose of this review address the participation of small animals in the spread of the disease, clinical aspects related to it, as well as discuss methods of diagnosis, therapeutic measures, prophylaxis and control of this disease.

Em decorrência da alteração presente nas rupturas diafragmáticas ser de natureza anatômica, o tratamento cirúrgico é o único indicado. As abordagens cirúrgicas mais utilizadas são a laparotomia pela linha média e a toracotomia intercostal, porém, a correção cirúrgica pode ser dificultada, principalmente quando houver perda de tecido, evolução crônica, ou quando a lesão no músculo diafragma for extensa, necessitando de procedimentos cirúrgicos mais apropriados, tal como a utilização de implantes biológicos ou sintéticos. Os vários tipos de implantes e enxertos testados para reparar os defeitos no músculo diafragma obtiveram bons resultados e baixas taxas de mortalidade, sugerindo uma nova alternativa no reparo de defeitos diafragmáticos

The benefits of proper nutrition and analgesia are closely linked when it comes to animals that are suffering from any illness and are hospitalized. In patients who are ill or under the stress of hospitalization, increase secretion of glucagon, catecholamines, cortisol and growth hormone antagonize the effects of insulin, leading to hyperglycemia and degradation of tissue proteins to provide substrate for gluconeogenesis. These changes result in loss of lean body mass, reflecting negatively on tissue repair processes, immune response and prognosis. Likewise, the pain induced by noxious stimulation can lead to protein catabolism, stress, immunosupression, delayed wound healing and acceleration of disease processes. This review confirms the nutrition and pain control importance in hospitalized patients, showing their physiological benefits and reduction in hospital stay when the clinician understands these benefits and the animals are treated with such care
