Serological Classification and Comparison of Cell Surface Hydrophobicity and Biofilm and Proteases Formation between the Clinical and Environmental Isolates of Pseudomonas Aeruoginosa
Background & Aims: Pseudomonas aeruoginosa is an opportunistic pathogen and an important cause of nosocomial infections. Different factors are involved in the pathogenicity of this bacterium. This study was performed to compare some factors associated with the virulence of clinical and environmental isolates of P. aeruoginosa. Methods: The present study was performed on 25 environmental isolate...
متن کاملIron uptake mechanisms in the fish pathogen Tenacibaculum maritimum.
We present here the first evidence of the presence of iron uptake mechanisms in the bacterial fish pathogen Tenacibaculum maritimum. Representative strains of this species, with different serotypes and origins, were examined. All of them were able to grow in the presence of the chelating agent ethylenediamine-di-(o-hydroxyphenyl acetic acid) (EDDHA) and also produced siderophores. Cross-feeding...
متن کاملTenacibaculosis infection in marine fish caused by Tenacibaculum maritimum: a review.
Tenacibaculum maritimum is the aetiological agent of an ulcerative disease known as tenacibaculosis, which affects a large number of marine fish species in the world and is of considerable economic significance to aquaculture producers. Problems associated with epizootics include high mortality rates, increased susceptibility to other pathogens, high labour costs of treatment and enormous expen...
متن کاملThe Complete Genome Sequence of the Fish Pathogen Tenacibaculum maritimum Provides Insights into Virulence Mechanisms
Tenacibaculum maritimum is a devastating bacterial pathogen of wild and farmed marine fish with a broad host range and a worldwide distribution. We report here the complete genome sequence of the T. maritimum type strain NCIMB 2154T. The genome consists of a 3,435,971-base pair circular chromosome with 2,866 predicted protein-coding genes. Genes encoding the biosynthesis of exopolysaccharides, ...
متن کاملPhenotypic characterization and description of two major O-serotypes in Tenacibaculum maritimum strains from marine fishes.
Tenacibaculum maritimum is the etiological agent of marine flexibacteriosis disease, with the potential to cause severe mortalities in various cultured marine fishes. The development of effective preventive measures (i.e. vaccination) requires biochemical, serological and genetic knowledge of the pathogen. With this aim, the biochemical and antigenic characteristics of T. maritimum strains isol...
