TL;DR: Evaluated pathogenicity of Plesiomonas shigelloides for "jundia" (Rhamdia quelen), different bacterial concentrations were inoculated via peritoneum and it was observed that intraperitoneal inoculation did not cause any change in the catfishes, regardless inoculated concentration.
Abstract: As worldwide aquaculture has grown, and intensification in fish raising, the animals are subject to bacterial diseases and others. With the aim of evaluating pathogenicity of Plesiomonas shigelloides for "jundia" (Rhamdia quelen), different bacterial concentrations (3 x 108 e 9 x 108 CFU - Colony Former Unit/ml) were inoculated via peritoneum. Eigthy four juvenile "jundia" averaging 24.37 ± 4,28g of weight and 14.42 ± 1,62cm of length were utilized. The inoculated animals were maintained for 21 days, in asbestos water tanks, at similar temperature, pH, alkalinity and hardness conditions. The "jundias" were slaughtered every other day for counting UFC/ml renal tissue. For daily inspections, it was observed that intraperitoneal inoculation of Plesiomonas shigelloides did not cause any change in the catfishes, regardless inoculated concentration. Bacteria counting in "jundias" kidneys was maintained between 105 and 106 UFC/ml until the 21st day, when the experiment was ended.

TL;DR: A case of infection for Pseudomonas aeruginosa and outbreaks caused by Bordetella bronchiseptica in chinchila farms from the region of Santa Maria, Southern Brazil is described.
Abstract: SUMMARY This report describes a case of infection for Pseudomonas aeruginosa and outbreaks caused by Bordetella bronchiseptica in chinchila farms from the region of Santa Maria, Southern Brazil. The affected animals presented apathy, anorexia, respiratory impairment and nasal secretion. The isolation of Pseudomonas aeruginosa was carried out through the culture of samples of lung whereas Bordetella bronchiseptica was obtained from lung, liver and swab of traqueal secretion. In this report, the clinical data and the pathological findings as well as the isolation and identification of these agents are described.
