taxonomic dissection of the genus micrococcus: kocuria gen. nov., nesterenkonia gen. nov., kytococcus gen. nov., dermacoccus gen. nov., and micrococcus cohn 1872 gen. emend.the results of a phylogenetic and chemotaxonomic analysis of the genus micrococcus indicated that it is significantly heterogeneous. except for micrococcus lylae, no species groups phylogenetically with the type species of the genus, micrococcus luteus. the other members of the genus form three separate phylogenetic lines which on the basis of chemotaxonomic properties can be assigned to four genera. these genera are the genus kocuria gen. nov. for micrococcus roseus, micrococcus varians, and mi ...19957547287
analysis of intestinal flora of a patient with congenital absence of the portal vein.a 14-year-old female patient, admitted for a closer examination of liver tumour (hepatocellular adenoma), was diagnosed as having a congenital absence of the portal vein. the blood ammonia level (approximately 120 micrograms dl-1) in the superior mesenteric vein was markedly low compared to the normal value of 300-350 micrograms dl-1 in the portal vein. the decreased ammonia concentration and urease activity of the patient's faeces were demonstrated. the dominant intestinal flora in the faeces o ...19938364525
