Since 2000, Macrorhabdus ornithogaster "megabacteriosis" has been diagnosed in the avian diseases laboratory in a diversity of avian species and varied spectrum of disease. The disease in some species (chickens, turkeys, guinea fowls) was clinically characterized by emaciation, prostration, loss of appetite, cachexia and death, with a typically chronic course. A more acute disease was observed in finches (canary-Serinus and zebra-Taeniopygia) and budgerigars (Melopsittacus undulatus). The large rod shaped organism, visible from 100 times magnification, with and without staining, could be detected in sick and also in reasonably normal individuals of some species, such as chickens, turkeys, quails and pigeons. In rheas (Rhea americana), ostriches (Struthio... |

Relata-se um caso fatal de sarcosporidiose em pássaro-preto (melro), Gnorimopsar chopi chopi, caracterizado por intensa prostração, respiração superficial e decúbito lateral. Embora não tenham sido observadas alterações significativas no sistema respiratório, o quadro clínico confundia-se com doença nesse sistema, em decorrência do comprometimento dos músculos ligados à respiração. |

Investigaram-se as causas da mortalidade de peixes ocorrida em janeiro de 2005 na bacia do Rio São Francisco, Brasil. Edwardsiella tarda foi isolada dos rins de pacu Myleus micans. O isolado, denominado Et-LIS, caracterizado por bastonetes Gram negativos móveis, foi identificado por testes bioquímicos e confirmado pelo kit comercial Bactray. A susceptibilidade a 10 drogas das 12 testadas foi determinada pelo método de difusão de discos, enquanto as características de virulência foram avaliadas mediante inoculação experimental em Cyprinus carpio e em Oreochromis spp. Ambas as espécies desafiadas apresentaram sinais compatíveis com infecção por E. tarda. As tilápias (Oreochromis spp.) morreram 48h após a inoculação, enquanto as carpas (Cyprinus carpio)... |

Resistance training evokes myocardial adaptation; however, the effects of a single resistance exercise session on cardiac performance are poorly understood or investigated. This study aimed to investigate the effects of a single resistance exercise session on the myocardial contractility of spontaneously hypertensive rats (SHRs). Male 3-month-old SHRs were divided into two groups: control (Ct) and exercise (Ex). Control animals were submitted to sham exercise. Blood pressure was measured in conscious rats before the exercise session to confirm the presence of arterial hypertension. Ten minutes after the exercise session, the animals were anesthetized and killed, and the hearts were removed. Cardiac contractility was evaluated in the whole heart by the... |

We studied the effects of the acute administration of small doses of lead over time on hemodynamic parameters in anesthetized rats to determine if myocardial contractility changes are dependent or not on the development of hypertension. Male Wistar rats received 320 µg/kg lead acetateiv once, and their hemodynamic parameters were measured for 2 h. Cardiac contractility was evaluated in vitro using left ventricular papillary muscles as were Na+,K+-ATPase and myosin Ca2+-ATPase activities. Lead increased left- (control: 112 ± 3.7 vs lead: 129 ± 3.2 mmHg) and right-ventricular systolic pressures (control: 28 ± 1.2vs lead: 34 ± 1.2 mmHg) significantly without modifying heart rate. Papillary muscles were exposed to 8 µM lead acetate and evaluated 60 min later.... |
