The use of DAPI reduces the time required for making AG determinations compared to standard methods because it eliminates the need to assess cell wall dissolution and cytoplasmic fusion, and lack of staining is presumptive evidence that the fused cells are dead as a result of imperfect fusion.

Role of pfkA and General Carbohydrate Catabolism in Seed Colonization by Enterobacter cloacae
Genetic and biochemical restoration experiments provide strong evidence that the quantities of reduced carbon sources found in seed exudates and the ability of microbes to use these compounds play important roles in the colonization of the spermosphere. Expand
Importance of pfkA for Rapid Growth ofEnterobacter cloacae during Colonization of Crop Seeds
The mutation in pfkA appears to decrease the level of colonization by E. cloacae for seeds that release small quantities of reduced carbon compounds by decreasing the size of the pool of compounds that support rapid growth by this bacterium. Expand
Biological Control of Damping‐off of Cucumber caused by Pythium ultimum with a Root‐Colonization‐Deficient strain of Escherichia coli
Results from this study indicate that E. coli is capable of suppressing damping-off of cucumber caused by P. ultimum and both strains 501R3 and S17R1 provided effective biocontrol of pre-emergence and post-emERGence damping of cucumbers caused by Pythium ultimum. Expand
Amino acids as reduced carbon sources for Enterobacter cloacae during colonization of the spermospheres of crop plants
Abstract Enterobacter cloacae 501R3 grew in vitro and in natural soil on seven amino acids, commonly found in seed exudates, when these compounds were supplied as sources of reduced C. A collectionExpand
Isolation and modulation of growth of a colonization-impaired strain of Enterobacter cloacae in cucumber spermosphere.
Enterobacter cloacae A-46 was isolated for use in an environmental containment strategy for genetically modified derivative strains with enhanced biocontrol activity and was incapable of proliferation in cucumber spermosphere in the absence of casamino acids. Expand
Broad spectrum anti-biotic activity and disease suppression by the potential biocontrol agent Burkholderia ambifaria BC-F
The demonstrated ability of isolate BC-F to suppress disease caused by animal and fungal pathogens of many crop plants may be due to the ability to persist for long periods in association with roots of diverse crop plants in different soils and the production of a metabolite(s) with broad spectrum anti-biotic activity.

Acute poisoning by selenious acid.
A 2 yo male child ingested approximately 15 ml of a Gun Blue solution containing selenious acid, nitric acid and copper nitrate and died 17 d after ingestion despite aggressive treatment. Expand
Use of a Colonization-Deficient Strain of Escherichia coli in Strain Combinations for Enhanced Biocontrol of Cucumber Seedling Diseases
Seed treatments containing combinations of Escherichia coli S17R1 and Burkholderia cepacia Bc-B provided significantly greater (P ≤ 0.05) suppression of cucumber seedling pathogens in a field soilExpand
Mutation of rpiA in Enterobacter cloacae decreases seed and root colonization and biocontrol of damping-off caused by Pythium ultimum on cucumber.
Experiments reported here indicate a key role for rpiA and possibly the pentose phosphate pathway in suppression of damping-off and colonization of subterranean portions of plants by E. cloacae. Expand
