Selective medium for recovering specific populations of rhizobia introduced into tropical soils.
Experiments were designed to evaluate the usefulness of antifungal agents and streptomycin for recovering low densities of rhizobia inoculated into tropical soils. The results showed that yeast-mannitol agar (pH 6.0) containing 500 mug of streptomycin, 400 mug of cycloheximide and 50 mug of benomyl or chlorothalonil per ml was the best selective medium.
متن کاملEcological indicators of native rhizobia in tropical soils.
The relationship between environment and abundance of rhizobia was described by determining the populations of root nodule bacteria at 14 diverse sites on the island of Maui. Mean annual rainfall at the sites ranged from 320 to 1,875 mm, elevation from 37 to 1,650 m, and soil pH from 4.6 to 7.9. Four different soil orders were represented in this study: inceptisols, mollisols, ultisols, and an ...
متن کاملReliability of the most-probable-number technique for enumerating rhizobia in tropical soils.
We used six rhizobium-legume systems to test the reliability of the most-probable-number (MPN) technique for enumerating rhizobia introduced into 14 sites representing four soil orders. The range-of-transition values (the number of dilution steps between the first not-entirely-positive and the last not-entirely-negative growth units) were compared for each species and for each soil. The probabi...
متن کاملCost effectiveness of influenza vaccination for specific populations in Iran
Introduction: Influenza viruses are the major respiratory pathogens worldwide and high-risk groups such as healthcare workers may develop severe forms of the disease. The purpose of this study was to evaluate the cost-effectiveness of influenza vaccination for 4 target groups including pregnant women, elderly people (aged over 65 years), healthcare workers and school-age children in Iran. Metho...
