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... |

The aim of this study was to isolate, genotype and evaluate the antimicrobial susceptibility of Clostridium perfringens found in species Tinamidae, Cracidae and Ramphastidae in Brazil. C. perfringens was isolated in 13 (5%) out of 260 swab samples and five (8.3%) out of 60 stool samples. All strains were classified as C. perfringens type A, and nine (50%) were positive for the beta-2 toxin-encoding gene. No strains were positive for the necrotic enteritis toxin B-like (NetB)-encoding gene. All isolates were susceptible to penicillin, metronidazole and vancomycin, whereas four (22.2%), five (27.8%) and 13 (72.2%) strains were considered resistant to erythromycin, oxytetracycline and lincomycin, respectively. |
