Hfq is an RNA-binding protein that plays an important role in many cellular processes. In this study, we examined the biological effect of the Hfq of Edwardsiella tarda, a severe fish pathogen with a broad host range that includes humans. To facilitate the study, a markerless hfq in-frame deletion wild type, TXhfq, was constructed. Compared to the wild type TX01, TXhfq exhibited (i) retarded pl...

Edwardsiella tarda is a Gram-negative enteric bacterium affecting both animals and humans. Recently, a type III secretion system (TTSS) was found in Ed. tarda. Such systems are generally used by bacterial pathogens to deliver virulence factors into host cells to subvert normal cell functions. Genome-walking was performed from the eseB and esrB genes (homologues of Salmonella sseB and ssrB, resp...

In this study, the effects of sublethal nitrite and sublethal ammonia on experimentally infected Nile Tilapia’s haematological and immunological parameters have been investigated. The groups were K: control group, Group A: ammonia exposed group, AB: infected with Edwardsiella tarda and exposed to ammonia, Group N: nitrite exposed group, NB: infected with E. tarda and exposed to nitrite, B: infe...

Knowing the entire sequence of the gene encoding the DNA gyrase Subunit A (gyrA) of Edwardsiella tarda could be very useful for confirming the role of gyrA in quinolone resistance. Degenerate primers for the amplification of gyrA were designed from consensus nucleotide sequences of gyrA from 9 different Gram-negative bacteria, including Escherichia coli. With these primers, DNA segments of the ...

Impediment to the aquaculture industry and consequently, impoverishment of Nigerian populace can be attributed several factors ranging from managemental infectious or noninfectious. Despite abundantly blessed land capacity nourishment, continues face losses. As part very important agents known cause high morbidity mortality across fish species is Edwardsiella tarda. E. tarda directly associated...
