@article{fdi:010026106, title = {{V}accine potential of a recombinant glutathione {S}-transferase cloned from {S}chistosoma haematobium in primates experimentally infected with an homologous challenge}, author = {{B}oulanger, {D}. and {W}arter, {A}. and {S}ellin, {B}ertrand and {L}indner, {V}. and {P}ierce, {R}.{J}. and {C}hippaux, {J}ean-{P}hilippe and {C}apron, {A}.}, editor = {}, language = {{ENG}}, abstract = {{P}atas monkeys were twice immunized with a #{S}chistosoma haematobium$-derived recombinant glutathione {S}-transferase ({S}h28{GST}) then challenged with an homologous calibrated challenge. {BCG} and {F}reund's {C}omplete {A}djuvant ({FCA}) were used as adjuvants in two distinct protocols. {S}pecific {I}g{C} and {I}g{A} antibody responses were intense and homogeneous in the animals receiving {S}h28{GST} in the presence of {FCA}, whereas {BCG} could only induce moderate and heterogeneous antibody titres. {N}o significant effect on worm burdens was evidenced 36 weeks post-infection in either group of {S}h28{GST}-immunized animals compared to their matched controls receiving an irrelevant protein. {A}lthough not significant, 50% reductions in the numbers of eggs located in all tissues ({FCA} group) and in the urogenital system ({BCG} group) were noted. {M}oreover, the total number of excreted eggs was dramatically diminished by 60% and 77% in the {BCG} and {FCA} groups, respectively. {T}hese reductions reached 75% and 80% in the urines of vaccinated monkeys. {B}ladder pathology was also reduced in the animals displaying the lowest urinary egg excretions. {T}here was no clear positive or negative correlate between antibody responses and individual levels of protection. {T}aken as a whole, our results show that {S}h28{GST} was capable of significantly reducing #{S}. haematobium$ worm fecundity in experimentally infected primates. {A}lthough {FCA} induced higher levels of protection, the efficacy of {BCG} as an adjuvant appeared sufficient to justify consideration of the future application of this new formulation as a vaccine against human urogenital schistosomosis.
