Studies on Argentine Phylacia species (Hypoxylaceae) using a polythetic taxonomic approach

A TAXONOMIC STUDY ON ALTERNARIA SPECIES IN IRAN (2)

In the continuation of studies on Alternaria species, some 500 isolates were obtained from seeds, soil and plant parts from various localities of Iran. Prior to morphological examination, pure cultures were obtained by single conidium and single chain methods. Descriptions for each taxon are based on cultures developed on potato carrot agar. Inoculated plates were incubated at 23-25°C under a c...

Taxonomic Studies on Canine and Feline Gastric Helicobacter Species

Taxonomic Studies on the Enterococci *

Although the term "Enterococcus" appeared in bacteriological literature as early as 1899 (Thiercelin26) this bacterial group has yet to assume the position merited by its occurrence and by its distinctive characteristics. The fault lies primarily in the failure of workers to cover all phases in the study of their strains and in an inability to correlate the results of different studies, rather ...

A taxonomic approach to evaluation of the charge state model using twelve species of sea anemone.

The charge-state model of electrophoretic variation was tested by comparing the distances between nearest electromorphs of five enzyme loci within polymorphic species and among pooled species of sea anemone. If the charge-state model is generally true, and in particular if it allows linear distance between electromorphs to be used as a measure of genetic distance, then electromorphs of differen...

Taxonomic re-evaluation of species in Talaromyces section Islandici, using a polyphasic approach

The taxonomy of Talaromyces rugulosus, T. wortmannii and closely related species, classified in Talaromyces sect. Islandici, is reviewed in this paper. The species of Talaromyces sect. Islandici have restricted growth on MEA and CYA, generally have yellow mycelia and produce rugulosin and/or skyrin. They are important in biotechnology (e.g. T. rugulosus, T. wortmannii) and in medicine (e.g. T. ...
