Taxonomy of Pseudomonas Piscicida (bein) Buck, Meyers, and Leifson.

STUDIES OF FLAVOBACTERIUM PISCICIDA BEIN: I. Growth, Toxicity, and Ecological Considerations.

Species of Flavobacterium are abundant in marine environments, occurring in sea water and sediments as well as in the slime and feces of various fish. The activity of flavobacteria in fish spoilage is not uncommon (Castell and Mapplebeck, 1952). Other than the studies of these latter workers, only the investigations of MacLeod and his associates (MacLeod et al., 1954, 1958) deal, to any extent,...

Bacterial taxonomy: a critique.

or neo-Adansonian taxonomy has also created considerable interest. That our conventional taxonomy has many shortcomings is obvious, and the purpose of this paper is to review the history of some areas of conventional taxonomy, to state my personal views for improvements, and to evaluate critically some publications on numerical taxonomy. If this paper is to have an impact for improvement, it se...

Boost symmetry in the Quantum Gravity sector

We perform a canonical quantization of gravity in a second-order formulation, taking as configuration variables those describing a 4-bein, not adapted to the space-time splitting. We outline how, neither if we fix the Lorentz frame before quantizing, nor if we perform no gauge fixing at all, is invariance under boost transformations affected by the quantization.

Usefulness of Leifson staining method in diagnosis of Helicobacter pylori infection.

The Leifson staining method was used to diagnose Helicobacter pylori infection and was compared to histology, culture, and the rapid urease test (RUT). Histology gave the best sensitivity (98%), compared to Leifson staining (97%), culture (92%), and RUT (85%) (P < 0.005). Leifson staining is a sensitive, rapid, economical method for diagnosis of H. pylori infection in dyspeptic patients.
