Similarities of Giardia antigens derived from human and animal sources

Analysis of proteins from membrane and soluble fractions of Giardia duodenalis trophozoites of two Brazilian axenic strains

“…In general, the electrophoretic patterns reported are complex and homogeneous, with the detection of multiple protein bands ranging from 140 to 10 kDa 21 , 122 to 10 kDa 2 or 250 to 14 kDa 24 . The overall homogeneity of the protein patterns is consistent with the results showed in previous investigations 2,7,21,24,25 that employed other strains. Heterogeneity has been observed in the 20-25 kDa and 50-56 kDa regions 7,26 .…”

“…The complexity of protein fractions of Giardia duodenalis trophozoites has been reported by several authors 2,5,6,7,12,21,25 . In our study, Fig.…”

“…Considering that the composition and complexity of Giardia strains might be associated with aspects of the host-parasite relationship, characterization of trophozoites proteins from axenic strains have been conducted in order to expand the knowledge of this parasite and to detect differences between strains 2,5,6,7,12,21,25 . The proteins of trophozoites have been studied in terms of their localization and with respect to their nature and properties.…”

Efficacy of oxfendazole for the treatment of giardiosis in dogs. Experiments in dog breeding kennels

“…Some strains of this protozoan have a zoonotic aspect: some animal strains being able to infect human. There are populations adjusted to each kind of host, but interspecific transmissions are still possible (Capon, 1989;Gasser, 1990;Hopkins, 1997;Meloni et al, 1995). Screening and struggle measures against this enteritic parasite are bound to expand.…”

“…It is considered by several authors to be a zoonosis, even though various adjusted strains host species are genetically singled out (Capon, 1989;Gasser, 1990;Hopkins, 1997;Thompson et al, 2000). Some strains seem to be able to infect human from livestock or dogs and vice versa, and, in the opposite, other strains seem to be very specific.…”
