The macrophage chemotactic activity of Edwardsiella tarda extracellular products.
The chemoattractant capabilities of Edwardsiella tarda extracellular products (ECP) were investigated from two isolates, the virulent FL6-60 parent and less virulent RET-04 mutant. Chemotaxis and chemokinesis were assayed in vitro using blind well chambers with peritoneal macrophages obtained from Nile tilapia, Oreochromis niloticus, 5 days following squalene injection. Non-purified ECP derived...
متن کاملExpression of an iron-regulated hemolysin by Edwardsiella tarda.
The ability of Edwardsiella tarda to hemolyse red blood cells was investigated. Most E. tarda strains (> 80%) produced a hemolysin when assayed by either an agar overlay or contact-dependent hemolysis technique. This activity was cell-associated (CAH) and not released into the culture supernatant under routine conditions. When quantified, E. tarda strains significantly produced 30-40-fold highe...
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 کاملMyonecrosis caused by Edwardsiella tarda: a case report and case series of extraintestinal E. tarda infections.
Edwardsiella tarda is an unusual human pathogen. It is primarily associated with gastrointestinal disease, although recent reports of extraintestinal disease are broadening the current understanding of the clinical spectrum of E. tarda. A series of 11 cases of extraintestinal E. tarda infection is presented, including the first reported case of myonecrosis in an immunocompetent patient. Wound i...
متن کاملMaternal colonization and neonatal sepsis caused by Edwardsiella tarda.
A case of neonatal sepsis caused by Edwardsiella tarda, a bacterium usually associated with freshwater ecosystems, is described. The infant's mother was immersed in lake water during the sixth month of pregnancy and had vaginal and gastrointestinal colonization with the same strain of E tarda as the infant at the time of delivery. This case suggests that maternal exposures to contaminated bodie...
