Classificado no gênero Morbillivirus da família Paramixoviridae, o vírus da cinomose possui RNA de fita simples de polaridade negativa, é causador de doença multissistêmica, altamente contagiosa e grave dos cães e carnívoros selvagens, e com elevado índice de mortalidade em animais não vacinados ou com falhas vacinais. Com o objetivo de avaliar as alterações histopatológicas no coração, particularmente na região do miocárdio ventricular esquerdo, de cães naturalmente infectados com o vírus da cinomose, foram estudados 35 animais, de ambos os sexos e com idades variadas. Das 35 amostras enviadas ao Laboratório de Medicina Veterinária Preventiva do Hospital Veterinário de Uberaba, 100% (35/35) mostrou-se soropositivas para a cinomose (técnica de imunoensaio em fase sólida) e tiveram no miocárdio ventricular esquerdo as seguintes alterações histopatológicas: miocardite, degeneração hialina, hiperemia e hemorragia, com 42,8% (15/35), 31,4% (11/35), 14,3% (5/35) e 11,4% (4/35), respectivamente. Tendo utilizado o teste Qui-Quadrado com nível de significância de 0,05, conclui-se que existe alta correlação (p=0,02) entre os animais infectados com o vírus da cinomose e as alterações histopatológicas observadas no miocárdio ventricular esquerdo.

Classified pertaining to the genus Morbillivirus of the Paramyxoviridae family, the canine distemper virus is a RNA single-stranded virus with negative polarity and causes a multisystemic disease, serious and highly contagious for dogs and wild carnivores, with a high mortality rate in non-vaccinated animals or with vaccine fails. With the objective to evaluate heart histopathological alterations, particularly in the left ventricular myocardium, in dogs naturally infected with canine distemper virus, 35 dogs, males and females of different ages, were studied. All the 35 samples sent to the Veterinary Hospital of Uberaba were serum-positive for distemper (immunoassay technique in solid phase) and had in the left ventricular myocardium the following histopathologic alterations: myocarditis, hyalin degeneration, hyperemia and hemorrhage, in 42.8% (15/35), 31.4% (11/35), 14.3% (5/35) and 11.4% (4/35), respectively. Having carried out the Qui-Quadrado test with a significancy level of 0.05, it can be concluded that there is a high correlation (p=0.02) between the infected animals with canine distemper virus and histopathological alterations found in the left ventricular myocardium.

There is a growing interest in microbial lipase production due to its great potential for industrial applications such as food additives, industrial reagents and stain removers, as well as for medical applications. Specially for medical applications a high degree of purity is required, which is accomplished with high resolution chromatographic techniques. Affinity chromatography is considered a very high resolution chromatographic technique. In this work the adsorption isotherms and kinetics of the adsorption of lipase from Geotrichum sp on biospecific resin were determined. The resin was prepared using EAH sepharose 4B gel (Pharmacia), made to react with oleic acid as the specific ligand.The lipase was produced in a five-liter fermenter, with both complex and synthetic media. Fermentation conditions were a temperature of 30°C, an aeration of 1VVM and an agitation of 400 rpm. Maximum lipase activity was around 28 U/ml after 10 hours of fermentation for the complex medium. The kinetic model and parameters were determined by dynamic fitting to experimental results using the fourth-order Runge-Kutta method.
