Virulence properties and enterotoxin production of Aeromonas strains isolated from fish.
The biological activities in vivo and in vitro of 59 motile Aeromonas spp. isolated from fish and water tanks were simultaneously analyzed in poikilothermic and homoiothermic systems. A total of 64.3% of the isolates tested were pathogenic for fish, and 62% of Aeromonas hydrophila and A. sobria isolates either virulent or nonvirulent for fish were enterotoxigenic. Although the majority of the s...
متن کاملDistribution and virulence gene comparison of Aeromonas strains isolated from diseased fish and water environment.
A total of 71 Aeromonas strains were isolated in the south of Jiangsu Province China in order to analyze the difference ofAeromonas spp. distribution between diseased fish and water environment. The sequence of 16S rDNA and gyrB demonstrated that the 71 Aeromonas isolates could be divided into 4 species, including A. veronii (55), A. hydrophila (11), A. salmonicida (3) and A. media (2). A. vero...
متن کاملInvestigation of several virulence properties among Vibrio alginolyticus strains isolated from diseased cultured fish in Tunisia.
We analysed 34 Vibrio alginolyticus strains isolated from gilthead sea bream Sparus aurata L. and sea bass Dicentrarchus labrax L. cultured in fish farms on the Tunisian Mediterranean coast for the presence of several virulence properties such as extracellular products (ECP) production, growth in iron-limiting conditions and survival in fish serum. The results obtained with different substrates...
متن کاملNo difference in enterotoxin production among Staphylococcus aureus strains isolated from blood compared with strains isolated from healthy carriers.
The production of enterotoxin A, B, C and D by 196 Staphylococcus aureus strains isolated from blood cultures and 95 strains from nasal carriers was investigated. Half of the bacteraemia strains were from patients who died with or because of their infection, the other half from patients who survived. The nasal strains were selected to match the bacteraemia strains regarding phage types. Overall...
متن کاملCharacterization and Distribution of Virulence Factors in Aeromonas hydrophila Strains Isolated from Fecal Samples of Diarrheal and Asymptomatic Healthy Persons, in Ilam, Iran
Aeromonas hydrophila secretes several extracellular proteins including enterotoxin, hemolysin and aerolysin that are associated with the bacterial virulence. Previous studies have shown that two hemolytic toxins, hemolysin A and aerolysin A contribute to the virulence of Aeromonas hydrophila. In the current study, a total of 50 strains of Aeromonas hydrophila, including 28 (56%) strains isolate...
