Nitrogenase activity (acetylene reduction activity) was found to occur universally in the Cyperus papyrus swamp in Lake Naivasha. Low rates of acetylene reduction activity (0.9–104.9 nmol C2H4 g d.wt. roots-1 h-1) were associated with excised roots of C. papyrus but higher rates of activity (89.0–280.4 nmol C2H4 g d.wt. roots-1 h-1) were associated with(More)
The distribution of Salmonella typhi, S. paratyphi A. and S. paratyphi C. agglutinins among 364 sera from a randomly selected group of healthy individuals in Nairobi and Naivasha (Kenya) were analysed in relation to bacteriologically confirmed cases of typhoid fever at the Kenyatta National Hospital (KNH).
