Complete Type III Secretion System of a Mesophilic Aeromonas hydrophila Strain

Abstract: We have investigated the existence and genetic organization of a functional type III secretion system (TTSS) in a mesophilic Aeromonas strain by initially using the Aeromonas hydrophila strain AH-3. We report for the first time the complete TTSS DNA sequence of an Aeromonas strain that comprises 35 genes organized in a similar disposition as that in Pseudomonas aeruginosa. Using several gene probes, we also determined the presence of a TTSS in clinical or environmental strains of different Aeromonas species: A… Show more

“…The pathogenicity of mesophilic aeromonads has been linked to a number of different determinants, such as toxins, proteases, outer-membrane proteins (Nogueras et al, 2000), lipopolysaccharide (LPS) (Merino et al, 1996), flagella Rabaan et al, 2001) and type III secretion system (Vilches et al, 2004). The O-antigen LPS plays an important role as a virulence factor in many Gram-negative bacteria (see Finlay & McFadden, 2006 for a review).…”

“…As primeiras possuem como fatores de virulência mais estudados as colicinas e as enterotoxinas termoestável (ST) e termolábil (LT), já as salmonelas possuem um aparato sofisticado para invasão e colonização, que envolve diversas proteínas e é conhecido como Sistema de Secreção Tipo III, utilizado também por outros microrganismos como Aeromonas hydrophila (MATTÉ MH, 1995 MATTÉ GR, 2003; BALABAN e RASOOLY, 2000; FIGUEIREDO, 2004;VILCHES et al, 2004;TORRES et al, 2005;FOSTER, 2005).…”

“…A virulência desses microrganismos está associada a diversos fatores como: presença de adesinas, produção de hemolisinas, toxinas e diversas proteínas envolvidas na aderência, invasão e desorganização/rearranjo cinético da célula alvo, dentre outros. (MATTÉ MH, 1995MATTÉ GR, 2003;NATARO e KAPER, 1998;BALABAN e RASOOLY, 2000;FIGUEIREDO, 2004;VILCHES et al, 2004;TORRES et al, 2005;FOSTER, 2005).…”
