| molecular characterization of cryptosporidium from animal sources in qinghai province of china. | the presence of cryptosporidium oocysts in 20 zoo animals of the xining zoo, 16 farm yaks and 42 farm goats in qinghai province, china was investigated by an immunofluorescence test (ift). the species and/or genotypes were determined by nested polymerase chain reaction (pcr) and sequence analysis of a fragment of the small subunit (ssu) rrna gene. cryptosporidium oocysts were found in 16 zoo animals, 2 yaks, and 15 goats by ift. the ift positive samples were further investigated by pcr, and 16 o ... | 2007 | 17701218 |
| genetic structuring and recent demographic history of red pandas (ailurus fulgens) inferred from microsatellite and mitochondrial dna. | clarification of the genetic structure and population history of a species can shed light on the impacts of landscapes, historical climate change and contemporary human activities and thus enables evidence-based conservation decisions for endangered organisms. the red panda (ailurus fulgens) is an endangered species distributing at the edge of the qinghai-tibetan plateau and is currently subject to habitat loss, fragmentation and population decline, thus representing a good model to test the inf ... | 2011 | 21585580 |
