Similarity Analysis of DNAs
In contrast to gram-negative bacteria, nearly all gram-positive bacteria must be digested with a lytic enzyme before they can be lysed by a detergent. In addition to lysozyme, which is the enzymeExpand
1 Determination of DNA Base Composition
Publisher Summary This chapter discusses the determination of DNA base composition. The deoxyribonucleic acid (DNA) of most organisms contains the purine bases adenine (A) and guanine (G) and theExpand
Deoxyribonucleic Acid Homologies Among Strains of Bacillus sphaericus
The genetic relatedness of 62 strains of Bacillus sphaericus, 4 strains of B. pasteurii, 6 strains of B. brevis, and 1 strain each of B. globisporus and B. aminovorans was examined byExpand
Geodesic Acoustic Waves in Hydromagnetic Systems
In toroidal systems with geodesic curvature an electrostatic acoustic mode occurs with plasma motion in the magnetic surfaces, perpendicular to the field. In typical stellarators this mode shouldExpand
Emendation of Bacteroidaceae and Butyrivibrio and Descriptions of Desulfomonas gen. nov. and Ten New Species in the Genera Desulfomonas, Butyrivibrio, Eubacterium, Clostridium, and Ruminococcus
The family Bacteroidaceae is emended to include bacteria that are monotrichous or lophotrichous. The genus Butyrivibrio is emended to include lophotrichous bacteria. Desulfomonas, a new genus ofExpand
Resistive instabilities in general toroidal plasma configurations
Previous work by Johnson and Greene on resistive instabilities is extended to finite‐pressure configurations. The Mercier criterion for the stability of the ideal magnetohydrodynamic interchange modeExpand
Taxonomy of the Lactobacillus acidophilus Group
A total of 89 strains designated Lactobacillus acidophilus were examined for physiological properties, type of lactic acid produced, cell wall sugar pattern, guanine plus cytosine content ofExpand
Use of Nucleic-Acid Homologies in the Taxonomy of Anaerobic Bacteria
Nucleic acid homology studies are providing a common base for establishing bacterial groups. Few phenotypic characteristics have consistently correlated with homology data among the various groups ofExpand
Phylogenetic Study of the Genus Campylobacter
The phylogenetic relationships of all species in the genus Campylobacter, Wolinella succinogenes, and other gram-negative bacteria were determined by comparison of partial 16S ribosomal ribonucleicExpand
Human Immunodeficiency Virus Type 1 (HIV-1)Quasispecies at the Sites of Mycobacterium tuberculosis InfectionContribute to Systemic HIV-1 Heterogeneity
ABSTRACT We have recently reported an increased heterogeneity in the human immunodeficiency virus type 1 (HIV-1) envelope gene (env) in HIV-1-infected patients with pulmonary tuberculosis (TB)Expand
