Swine influenza: clinical, serological, pathological, and virological cross‐sectional studies in nine farms in Argentina

BACKGROUND Influenza A viruses (IAV) are important pathogens responsible for economic losses in the swine industry and represent a threat to public health. In Argentina, clinical, pathological, and virological findings suggest that IAV infection is widespread among pig farms. In addition, several subtypes of IAV, such as pH1N1, H3N2, δ1H1N1, and δ2H1N2, have been reported. OBJECTIVES To evalu...

Studies on Immunity to Swine Influenza

Of the two etiological components of swine influenza, only the filtrable virus possessed immunizing properties. H. influenzae suis, while essential to the production of the disease, played only a secondary and contributory rôle and, alone, conferred no immunity. Serum of swine convalescent from the filtrate disease neutralized the swine influenza etiological complex of organism and virus. Intra...

Comparative studies on the ultrastructure of nucleoli in human lymphosarcoma cells and leukemic lymphocytes.

various cultured cells by actinomycin D or chromomycin A3 (1 1, 12, 23). In all these cell types, the nucleolar shape seems to reflect a low rate of nucleolar RNA synthesis. Although the ultrastructural morphology of undifferen tiated and well-differentiated cells of lymphosarcomas (poorly and well-differentiated malignant lymphomas) is very similar to leukemic lymphocytes in various stages of ...

Studies on the distribution of blood flow in amelanotic melanoma and reticulum cell lymphosarcoma during growth.

SUMMARY The distribution of intravenously administered ‘69Ybmicro spheres, 88RbCl, and a vital staining dye has been examined in amelanotic melanoma and reticulum cell lymphosarcoma of the hamster. The intensity of the dye stain within the tumor tissue was proportional to the uptake of the isotopic indicators by the tissue. Intensely stained tumor tissue has a significantly greater uptake of ...
