Detection and intensity of urease activity in enterobacteriaceae greatly varies as a function of the media or techniques used, or both. A comparative investigation on several solid and liquid media led us to the following conclusions. (i) Detection of Proteus spp. can be adequately performed with the highly selective solid medium described by Cook (1948), as well as with the different liquid me...

the formation of chlamydospores of phytophthora parsiana, a newly described high temperature tolerant pathogen of woody plants, were investigated in culture media and in infected roots of susceptible host plants. different solid agar media and cleared v-8 juice broth were inoculated with different isolates of p. parsiana and incubated for four days at room temperature before they were transferr...
