ANTAGONISMS AMONG ENTERIC PATHOGENS AND COLIFORM BACTERIA

Antagonisms among enteric pathogens and coliform bacteria.

That some strains of the coliform group of bacteria exert inhibitory effects on other microorganisms, when grown in association in liquid media, was reported first by Nissle in 1916. Because of the multiplicity of factors involved when organisms are growing in heterogeneous mixtures in liquid media, the nature of the inhibiting agent is difficult to ascertain. Gratia of Belgium (1925) observed ...

Molecular and evolutionary relationships among enteric bacteria.

Classification of bacterial species into genera has traditionally relied upon variation in phenotypic characteristics. However, these phenotypes often have a multifactorial genetic basis, making unambiguous taxonomic placement of new species difficult. By designing evolutionarily conserved oligonucleotide primers, it is possible to amplify homologous regions of genes in diverse taxa using the p...

Antibiotic resistance among coliform and fecal coliform bacteria isolated from sewage, seawater, and marine shellfish.

Seawater and shellfish samples collected in the vicinity of a marine sewage outfall were examined for the incidence of antibiotic resistance among coliform and fecal coliform bacteria over a 2-year period. Seventy percent or more of these two groups of bacteria from both sources were resistant to one or more antibiotics. Forty-five percent of the isolates resistant to streptomycin or tetracycli...
