Protection between strains of Papaya ringspot virus: type w in zucchini squash involves competition for viral replication sites
(São Paulo - Escola Superior de Agricultura "Luiz de Queiroz", 2008)
A mild strain of Papaya ringspot virus - type W (PRSV-W), named PRSV-W-1, has proved to be very effective in the control of the disease in zucchini squash plants under greenhouse and field conditions. The aim of this work ...
Cellular immune responses in mice immunized with Anisakis simplex larval antigens
(Springer, 2001-05-01)
Cellular immune responses to Anisakis simplex L3 antigens were investigated in BALB/c mice injected subcutaneously with a homologous crude extract (CE). Popliteal lymph nodes (PLN) were found to be increased in size and ...
