Agriculturally important grasses contain numerous diazotrophic bacteria, the interactions of which are speculated to have some other benefits to the host plants. In this study, we analyzed the effects of a bacterial endophyte, Azospirillum sp. B510, on disease resistance in host rice plants. Rice plants (Oryza sativa cv. Nipponbare) were inoculated with B510 exhibited enhanced resistance agains...

Pseudomonas aeruginosa is one of the most host-susceptible pathogenic bacteria to cause acute and chronic infections in humans animals. Notably, its infection can especially fatal infectious pneumonia minks. Many previous mink studies have investigated pathology, pathogenesis, serology, antimicrobial resistance, virulence gene, vaccination, related diseases P. aeruginosa. However, relationship ...

1. Lysine deficiency has been produced in rats by placing the weanling animals on an experimental diet in which gluten replaced the casein of the control diet. Both diets were complete in all other known requirements. 2. The resistance of the deficient animals to a subcutaneous challenge of several concentrations of B. anthracis spores, was decreased. Deaths occurred within 2 days post inoculat...

As biologic organization became increasingly complex during the evolutionary process, evidently survival value became attached to the development of hormonally mediated regulatory mechanisms. It would not be surprising to find that as mechanisms of resistance to infection also became more complex, these also came under hormonal influence to some degree. Thus, the study of the influence of hormo...
