Occurrence of root parsley pathogens inhabiting seeds

How Pathogens Affect Root Structure

Several groups of soil microorganisms cause diseases to the roots. These “soilborne” plant pathogens are particularly challenging since they often survive in soil for many years and each crop may be susceptible to several species. They belong to various systematic groups. Major groups are oomycetes, fungi, bacteria, protists, and nematodes. Few soilborne viruses affect vegetable crops. The impa...

Phylogeny and taxonomy of root-inhabiting Cryptosporiopsis species, and C. rhizophila sp. nov., a fungus inhabiting roots of several Ericaceae.

Three Cryptosporiopsis species have thus far been isolated from roots of woody plants. A fourth species, which was recently isolated from roots of Calluna vulgaris, Erica tetralix, Vaccinium vitis-idaea, and V. myrtillus in The Netherlands, is described here as new. Sporulation on the natural substratum has not been observed and the morphological description of this fungus is therefore based on...

In vitro antimicrobial effect of different root canal sealers against oral pathogens

Background and Purpose: Root canal therapy is the primary method for the treatment of an infected pulp in modern dentistry. The main aim of endodontic treatment is the elimination of bacteria and their products from infected root canals. In this study, we attempted to investigate the antimicrobial activity of three root canal sealers against oral pathogens. Materials and Methods: The antimic...

Occurrence of periodontal pathogens among patients with chronic periodontitis

The aim of the present study was to evaluate the presence of the periodontal pathogens that form the red complex (Tannerella forsythia, Porphyromonas gingivalis and Treponema denticola) and Aggregatibacter actinomycetemcomitans in patients with chronic periodontitis. The sample consisted of 29 patients with a clinical and radiographic diagnosis of chronic periodontitis based on the criteria of ...
