Helper bacteria and pathogenicity assessments

New Phytologist, 1999
In the field, pathogens exist in a diverse and dynamic ecological environment with other organisms (Blakeman, 1993; Preece & Dickinson, 1971). We tend to assume that these other organisms are ‘benign’ or perhaps in competition with the pathogen to occupy a particular niche.

Salmonella and other pathogenic bacteria

Science of The Total Environment, 1981
The bacterial origin of waterborne diseases was discovered at the turn of this century. Introduction of slow sandfiltration, chlorination, and bacteriological control dates back to the same period. Although greater concern is given to-day to chemical pollutants or to viruses, bacteria are still a menace to countries with advanced water treatment ...

Proteins of Pathogenic Bacteria

1948
Publisher Summary An understanding of the factors and mechanisms determining the virulence of pathogenic organisms, the nature of the toxins and antigens that they produce, and the nature of the immune response are increasingly dependent on developments in the field of protein chemistry. The usefulness of quantitative immunochemical methods as an aid

Genetic variation in pathogenic bacteria

Trends in Genetics, 1992
In contrast to textbook ideas of pure cultures and defined strains, genetic variation is a fact of life in the microbial world. It not only allows pathogens to establish themselves in their chosen host, but also allows them to resist that host's subsequent attempts to evict them.

Evolutionary genomics of pathogenic bacteria

Trends in Microbiology, 2001
Complete genome sequences are now available for multiple strains of several bacterial pathogens and comparative analysis of these sequences is providing important insights into the evolution of bacterial virulence. Recently, DNA microarray analysis of many strains of several pathogenic species has contributed to our understanding of bacterial diversity,

Visualization of Pathogenicity Regions in Bacteria

Genetica, 2000
We show here how pathogenicity islands can be analysed using GenomeAtlases, which is a method for visualising repeats, DNA structural characteristics, and base composition of chromosomes and plasmids. We have applied this method to the E. coli plasmid pO157, and the Y. pestis plasmid pPCP1.

Pathogenic strategies of enteric bacteria

Nature, 2000
Enteric bacteria use a limited array of macromolecular systems to implement diverse pathogenic strategies. The cellular targets of several enteric virulence factors have recently been identified. The themes that have emerged from these studies include the exploitation of molecules that regulate the actin cytoskeleton and the activation of apoptotic ...
