The aquatic environment is the habitat of many microorganisms, including Plesiomonas shigelloides and Aeromonas species which are pathogenic to human and animals. In the present investigation, we evaluated the occurrence of these pathogens from marine mammals beached or accidentally captured by fishing net in southeastern (RJ) and southern (RS) coastal Brazilian regions. A total of 198 swabs fr...

A total of 103 strains of Aeromonas spp. isolated from clinical and from environmental samples was compared by using SDS-PAGE of periplasmic proteins patterns. Strains isolated from Polish children suffering from gastroenteritis did not appear similar to strains isolated from human living in Hong-Kong. Aeromonas sp. strains did not show a tendency to cluster according to their origin. Our resul...

Background: Motile Aeromonas species cause heavymortalities in carp farms during spring and summer in Iran. Objectives: The aim of this study was to detect phenotypicand genotypic characterization of motile Aeromonas species isolated fromdiseased carps in some northern and southern provinces of Iran. Methods: A number of 40 samples from 22 fish farms werecollected. The identified motile Aeromon...

A total of 82 strains of presumptive Aeromonas spp. were identified biochemically and genetically (16S rDNA-RFLP). The strains were isolated from 250 samples of frozen fish (Tilapia, Oreochromis niloticus niloticus) purchased in local markets in Mexico City. In the present study, we detected the presence of several genes encoding for putative virulence factors and phenotypic activities that may...

The use of antioxidants and antibacterial compounds obtained from natural sources is important for human animal health, as well controlling diseases. aim this study was to evaluates the antioxidant potentials effects water extracts C. sativa, U. dioica, A. deliciosa aurantium against selected Gram-negative (Vibrio harveyi, Vibrio vulnificus, anguillarum, rotiferianus, campbellii, ponticus Aerom...

An acute infectious disease of northern sheatfish (Silurus soldatovi) was found in a commercial aquaculture pond Tianjin, China. Herein, two dominant bacterial strains were isolated from naturally diseased and identified as Aeromonas veronii Vibrio cholerae. Seven healthy seven fish that collected the used for gut microbiota analysis by high-throughput 16S rRNA gene sequencing. The α-diversity ...

Genes encoding two major outer membrane proteins (OMPs) of the bacterial pathogen Aeromonas veronii, Omp38 and Omp48, were used to construct DNA vaccines. The protective effect of such vaccines against motile aeromonad septicaemia was evaluated in spotted sand bass (Paralabrax maculatofasciatus), an endemic species of the Mexican Northwest Pacific coast and a potential resource for the aquacult...

Collagen-binding protein (CNBP) synthesized by Aeromonas veronii is located conserved within the subcellular fraction. The results of this study show that 98% of the total CNBP produced by Aer. veronii is present in the extracellular medium, and that the remaining CNBP is distributed either on the cell surface, within the periplasm or anchored on the outer membrane. CNBP is specifically secrete...

Traveler's diarrhea is the most common health problem of international travelers. We determined the prevalence of Aeromonas spp. associated with traveler's diarrhea and analyzed the geographic distribution, clinical features, and antimicrobial susceptibility. Aeromonas spp. were isolated as a cause of traveler's diarrhea in 18 (2%) of 863 patients. A. veronii biotype sobria was isolated in nine...
