查询词典 pathogens

The protozoa were isolated from field animal blood, vectors, pathogenic tissue and secretions. Based on differences of the pathogen morphology, vector species, experimental infected animals, single parasite clone and parasitic tissues, protozoiasis pathogens from different areas and animals in China were isolated and the vectors and transmission mode were also determined by vector transmission trial. Sequence analysis of 18S rRNA gene was used to study the phylogeny of partial isolated protozoa.
