RESUMO
Alcaligenes xylosoxydans protected pigeonpea from Fusarium wilt in a pot experiment and field trials. When seeds of pigeonpea (C. cajan) were treated with A. xylosoxydans and sown in soil infested with Fusarium, the incidence of wilt was reduced by 43.5% and resulted in 58% higher grain yield. The antifungal activity of A. xylosoxydans was based on chitinase production and was comparable in efficacy to commercial antifungal agents such as benlate, monitor WP, thiram and bavistin.

The enterococcus has emerged as one of the most important nosocomial pathogens: an organism with the ability to develop resistance to all available antibiotics. This article details the historic significance of the enterococcus and delineates the clinical presentations and therapeutic options for the clinician. In addition, recent guidelines from the Centers for Disease Control and Prevention are reviewed, and additional steps are suggested to prevent the spread of this scourge of the 1990s.
