Use of a novel phosphatase test for simplified identification of species of the tribe Proteeae
No full textPhosphatase activity of 334 isolates of the tribe Proteeae carefully identified to species level has been evaluated by using both a number of conventional tests and three versions of the novel methyl green-phenolphthalein (MGP) method (G. Satta. R. Pompei, G. Grazi, and G. Cornaglia, J. Clin. Microbiol. 26:2637-2641, 1988). We found that the different species of Proteeae show different and easily distinguishable. behaviors by the MGP method, while all of them behave in a uniform way in the conventional tests. On studying the mechanism underlying these different behaviors, we found that the phosphatase activity of Morganella morganii and Providencia stuartii is higher than that of all other members of the family Enterobacteriaceae. Furthermore, we found that all P. stuartii strains display the property (shared by virtually none of the other species of Enterobacteriaceae) of excreting significant amounts of phosphatase. This extracellular activity is reliably detected by the MGP method but not by conventio

I dati etnografici tra dono e scambio: note su proprietà, controllo e uso delle informazioni etnografiche
No full textIl saggio analizza le diverse concezioni antropologiche riguardo ai "dati etnografici": si tratta di doni, merci o altro? Che tipo di rapporti di scambio sono istituiti tra coloro che forniscono i dati e coloro che li ricevono? A quali trasformazioni vanno incontro le pratiche di produzione dei dati etnografici in seguito all'emergere del problema della restituzione e del tema della proprietà culturale
