Profile and protective role of 61kDa and 47kDa antigens of Edwardsiella tarda in rohu (Labeo rohita)
Edwardsiella tarda is a versatile pathogen that could survive in different environmental conditions and infect economically important fish species. The whole cell antigenic proteins were extracted from E. tarda and assessed via Western blot using anti E. trada rohu and anti E. trada rabbit serum. Two strong reacted proteins with antibodies were recovered viz 61 kDa and 47 kDa from SDS PAGE gels...
متن کاملComparative proteomic analysis of extracellular proteins of Edwardsiella tarda.
A comparison of extracellular proteins of virulent and avirulent Edwardsiella tarda strains revealed several major, virulent-strain-specific proteins. Proteomic analysis identified two of the proteins in the virulent strain PPD130/91 as flagellin and SseB, which are virulence factors in bacterial pathogens. PCR amplification and DNA sequencing confirmed the presence of the genes that encode the...
متن کاملDomain analysis of the Edwardsiella tarda ferric uptake regulator.
Recent studies have shown that the ferric uptake regulator (Fur) of Edwardsiella tarda (Fur(Et)) shares high sequence identity with the Escherichia coli Fur (Fur(Ec)) at the N-terminal DNA-binding region. In the present study, the functional importance of the C-terminal region of Fur(Et) was investigated. It was found that Fur(Et) bearing deletion of the C-terminal 12 residues still possesses m...
متن کاملIsolation of Edwardsiella tarda from swine.
Edwardsiella tarda was isolated from the intestinal tract of a 2-month-old pig. This is the first reported isolation of Edwardsiella tarda from swine in the United States. Swine have been reported as potential carriers of Edwardsiella tarda, but pathogenicity of this organism for swine has not been determined. Although the pig had access to several farm ponds, the exact source of infection was ...
متن کاملNatural colistin resistance in Edwardsiella tarda.
All of 37 recent human isolates of Edwardsiella tarda were resistant to colistin. All strains were resistant to 6.3 mug of sodium colistimethate per ml; 82% of them were resistant to 100 mug/ml. With 34 Salmonella strains, the average minimal inhibitory concentration (MIC) was 1.6 mug of sodium colistimethate per ml. There was virtually no overlapping of MIC values between both groups of bacter...
