| natural infection with cryptosporidium galli in canaries (serinus canaria), in a cockatiel (nymphicus hollandicus), and in lesser seed-finches (oryzoborus angolensis) from brazil. | proventricular infection by cryptosporidium sp. or cryptosporidium galli has been associated with mortality, weight loss, diarrhea, and pasty feces. the purpose of this study is to report the occurrence of natural c galli infection in canaries (serinus canaria), in a cockatiel (nymphicus hollandicus), and in lesser seed-finches (oryzoborus angolensis) with clinical complaints of apathy and sporadic mortality. screening for cryptosporidium spp. using microscopic examination of fecal samples and s ... | 2008 | 19166068 |
| molecular characterization of cryptosporidium spp. from fecal samples of birds kept in captivity in brazil. | the aim of this study was to determine the prevalence of cryptosporidium species and genotypes in birds kept in captivity in brazil. a total of 966 samples from 18 families of birds was collected and stored in 5% potassium dichromate solution at 4 degrees c until processing. oocysts were purified in sheather sugar solution following extraction of genomic dna. molecular analyses were performed using nested-pcr for amplification of fragments of the 18s subunit of rrna gene and of the actin gene. a ... | 2009 | 19683397 |
| physical, epidemiological, and molecular evaluation of infection by cryptosporidium galli in passeriformes. | due to the scarcity of information related to the epidemiology of cryptosporidium infection in passerine birds, this study aimed to determine the periodicity of fecal shedding of cryptosporidium spp. oocysts, after natural infection, and its clinical signs, mortality, and molecular characterization. four hundred eighty fecal samples were collected from 40 birds, including 372 samples from 31 adult birds and 108 samples from nine young birds (up to 12 months old), housed in five aviaries, monthly ... | 2010 | 20407911 |
