| sarcocystis lindsayi-like (apicomplexa: sarcocystinae) of the opossum (didelphis aurita) from southeastern brazil. | sporocysts of sarcocystis were obtained from intestinal scrapings of three out of five opossums (didelphis aurita) trapped in the southeastern region, of the state of rio de janeiro, brazil. fifteen caged budgerigars (melopsittacus undulatus) received, orally, twenty-six sporocysts in 500 ml pbs, but only five belonging to one of the groups developed clinical signs, that consisted of anorexia, lethargy, ruffled feathers and dyspnoea, and parasitism in tissues. two of the five budgerigars died on ... | 2008 | 20059875 |
| didelphis aurita (marsupialia: didelphidae): a new host for sarcocystis lindsayi (apicomplexa: sarcocystidae). | nine opossums, didelphis aurita , were captured in the city of seropédica, state of rio de janeiro, brazil and examined for species of sarcocystis. sporocysts were observed in the mucosal scrapings of the small intestine from 3 opossums. five budgerigars, melopsittacus undulatus , were infected with sporocysts from each of these infected opossums and 5 budgerigars were used as controls. of the 15 sporocyst-treated budgerigars, 5 birds that received sporocysts from 1 of the infected opossums deve ... | 2012 | 22571294 |
| identification of opossums didelphis aurita (wied-neuweid, 1826) as a definitive host of sarcocystis falcatula-like sporocysts. | this study was conducted to identify the sarcocystis species that infect the opossum didelphis aurita in order to determine which sporocysts they are excreating in to the environment and help determine the role of d. aurita in the epidemiology of sarcocystis. sporocysts were obtained from intestinal tracts of 8 of 13 d. aurita trapped in rio de janeiro state, brazil, and were orally inoculated into melopsittacus undulatus and balb/c nude mus musculus. portions of organs and muscles were processe ... | 2018 | 29192336 |
