| The aim of the present study was to determine whether lipoarabinomannan (LAM), in combination with Freund’s incomplete adjuvant (FIA), was able to improve cell-mediated and antibody-mediated immune responses against ovalbumin (OVA) in cattle. Twenty-three calves were assigned to four treatment groups, which were subcutaneously immunized with either OVA plus FIA, OVA plus FIA and LAM from Mycobacterium avium subsp avium, FIA plus LAM, or FIA alone. Lymphoproliferation, IFN-γ production and cell subpopulations on peripheral blood mononuclear cells before and 15 days after treatment were evaluated. Delayed hypersensitivity was evaluated on day 57. Specific humoral immune response was measured by ELISA. Inoculation with LAM induced higher levels of... |

| La leishmaniasis visceral es una enfermedad zoonótica producida por el protozoario Leishmania infantum (syn. chagasi) transmitida por el flebótomo Lutzomyia longipalpis y que tiene al canino como principal reservorio en áreas urbanas y periurbanas. En el presente trabajo se realizó un estudio electroforético retrospectivo de 40 sueros de caninos enfermos con diagnóstico parasitológico confirmado de leishmaniasis obtenidos entre los años 2006 y 2008 en la ciudad de Posadas, provincia de Misiones, Argentina. El 80 % (32 de 40) de las muestras presentaron alteraciones en el perfil electroforético caracterizadas por la disminución de la relación albúmina/globulina y la presencia de hipergammaglobulinemia de tipo policlonal en el 52,5 % de los casos (21 de 40)... |
