| novel lineages of giardia intestinalis identified by genetic analysis of organisms isolated from dogs in australia. | infection of suckling mice with giardia trophozoites recovered from the intestines of 11 dogs autopsied in central and southern australia in each case produced an established isolate. in contrast, only 1 isolate was obtained by inoculation of faecal cysts. the organisms grew poorly in comparison with isolates from humans or non-canine animal hosts. light microscopy revealed that the trophozoites had median bodies with the 'claw hammer' appearance typical of g. intestinalis (syn. g. duodenalis, g ... | 1998 | 9481769 |
