| seroprevalence of cryptosporidium parvum infection of dairy cows in three northern provinces of thailand determined by enzyme-linked immunosorbent assay using recombinant antigen cpp23. | cryptosporidium parvum is the most frequent parasitic agent that causes diarrhoea in aids patients in thailand. cryptosporidiosis outbreaks in humans may be attributed to contamination of their drinking water from infected dairy pastures. a 23-kda glycoprotein of c. parvum (cpp23) is a sporozoite surface protein that is geographically conserved among c. parvum isolates. this glycoprotein is a potentially useful candidate antigen for the diagnosis of cryptosporidiosis by enzyme-linked immunosorbe ... | 2009 | 20698436 |
| seroprevalence of neospora caninum infection in dairy cows in northern provinces, thailand. | neospora caninum, an obligate intracellular protozoan parasite, is the causative agent of neosporosis, recognized as a major cause of bovine abortion around the world. thailand is a developing agricultural country located in southeast asia. livestock developments particularly in dairy cows of this country have been hampered by low productivity including milk and slow growth rate due to the impact of many pathogens including n. caninum. currently, there is no effective method for control of neosp ... | 2014 | 24827103 |
