| 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 |
| cryptosporidium spp. in pet birds: genetic diversity and potential public health significance. | to characterize the prevalence and assess the zoonotic transmission burden of cryptosporidium species/genotypes in pet birds in henan, china, 434 fecal samples were acquired from 14 families of birds in pet shops. the overall prevalence of cryptopsoridium was 8.1% (35/434) by the sheather's sugar flotation technique. the cryptosporidium-positive samples were analyzed by dna sequence analysis of the small subunit (ssu) rrna gene. three cryptosporidium species and two genotypes were identified, in ... | 2011 | 21557938 |
