| a mathematical model for the 1973 cholera epidemic in the european mediterranean region. | for the cholera epidemic that occurred in the european mediterranean region in the summer of 1973, a simple deterministic mathematic model is proposed; it consists of a system of two ordinary differential equations which concern the evolution of the human infective population in a town community and of bacteria population in the sea. it is conjectured that the infection process obeys a non linear saturation-type law. a phase space analysis is performed for the system of equations. conclusions ar ... | 1979 | 538301 |
| bacterial flora of the schistosome vector snail biomphalaria glabrata. | the aerobic heterotrophic bacterial flora in over 200 individuals from 10 wild populations and 3 laboratory colonies of the schistosome vector snail biomphalaria glabrata was examined. internal bacterial densities were inversely proportional to snail size and were higher in stressed and laboratory-reared snails. the numerically predominant bacterial genera in individual snails included pseudomonas, acinetobacter, aeromonas, vibrio, and several members of the enterobacteriaceae. enterobacteriacea ... | 1979 | 539821 |
| asparaginase production by human clinical isolates of vibrio succinogenes. | three human isolates of vibrio succinogenes produced asparaginase. apparent km's were 87,220, and 320 microm. the rate of glutamine hydrolysis was between 2.8 and 3.5% of the rate of asparagine hydrolysis. asparaginase production was not induced by ammonium ions, and enzyme yields were lower than those obtained with the rumen strain. | 1979 | 539825 |
