RESUMEN
Because of structural and philosophical changes in health care, social work practitioners are having to interact more with other practitioners in health care settings. Many of those interactions are interdisciplinary and often involve an understanding of the application of professional values and ethics. The authors have suggested that social workers' influence on ethical decision making is correlated directly to their ability to contribute to those decisions. In their study, the authors tested five independent variables and one dependent variable to show the factors that are related significantly to social workers' influence on ethical decision-making processes in multidisciplinary health care settings.

A reduction in the viability of cowpea rhizobia was observed when Rhizobium trifolii IARI and cowpea Rhizobium strain 3824 were inoculated together in soil. The reduction in number of cowpea rhizobia in soil was found to be associated with the reduction in number of nodules per plant and retardation in plant growth. An antimicrobial substance was isolated from R. trifolii which, on electron microscopic investigation, demonstrated the presence of several phage-like structures.
RESUMEN
Rhizobium trifolii strains IARI and Rel-1 produced substances with broad and narrow activity spectra, respectively. Reproducible inhibitory zones of various sizes produced by R. trifolii IARI (2 to 14 mm) and R. trifolii Rel-1 (2 to 6 mm) were detected, depending upon the indicator organism used. The maximum production of these substances by both strains of R. trifolii was observed on l-arabinose agar. A preliminary characterization of the antimicrobial substance produced by strain IARI showed resistance to heat (75 to 80 degrees C for 45 min), trypsin, lysozyme, DNase I, and RNase A. On the other hand, the substance produced by strain Rel-1 showed sensitivity to heat (75 to 80 degrees C for 45 min) and trypsin, but resistance to lysozyme, RNase A, and DNase I.
