systematics of primary osmotrophic euglenids: a molecular approach to the phylogeny of distigma and astasia (euglenozoa).	nuclear-encoded ssu rrna genes from nine strains of distigma and three strains of astasia were sequenced and analysed phylogenetically with maximum-likelihood and maximum-parsimony methods. it could be demonstrated that the genus distigma is paraphyletic, consisting of two distinct clades: one comprises four strains of the type species, distigma proteus, and the other includes four strains of distigma curvatum, distigma gracile, distigma sennii and distigma elegans. these findings are well corro ...	2003	12710635
trends in antimicrobial susceptibilities among enterobacteriaceae isolated from hospitalized patients in the united states from 1998 to 2001.	longitudinal surveillance of enterobacteriaceae for antimicrobial susceptibility is important because species of this family are among the most significant and prevalent human pathogens. to estimate rates of in vitro antimicrobial susceptibility among hospitalized patients in the united states, data from the surveillance network were studied for 14 agents tested against 10 species of enterobacteriaceae (n = 384,279) isolated from intensive-care-unit (icu) patients and non-icu inpatients from 199 ...	2003	12709339

effect of rho family gtp-binding proteins on amoeba proteus.	while there is a number of studies on the effects of rho gtpases on the actin-based cytoskeleton in higher eukaryotes, studies in protozoans are rather limited. the problem seems to be intriguing since the structure of protozoan cytoskeletons is distinct from most vertebrate cells. by blocking endogenous rho family proteins of highly motile amoeba proteus with c3 transferase and antibodies against human rhoa and rac1, we tried to assess the in vivo role of these proteins in amoebae. in migrating ...	2003	12664280
