Proteínas transmembranales de organismos tipo rickettsia (OTR) en animales acuáticos: Factores de adherencia, invasión e infección

Abstract: Abstract.-Besides participating in the transport of essential compounds and as recipients of phages, transmembrane proteins of rickettsia-like organisms (RLO), play an important role in the infection process of commercially important organisms such as fish, mollusk and crustaceans. Recently a new classification of RLO which divides them into four groups was reported: ancestral, typhus, the spotted fever and transitional. To date, only the typhus (TG) and spotted fever (SFG) groups have been reported as pathoge… Show more

“…Therefore, we hypothesize that WS disease requires the presence of the Candidatus Xenohaliotis californiensis along with a significant drop in the relative abundance of Mycoplasma, causing a concomitant decrease in Mycoplasma / Candidatus Xenohaliotis californiensis ratio, as observed in our study. A potential mechanism of Mycoplasma -induced protection might be based on the presence of sialic acid lyase activity degrading the α 2,3 sialic acid residues at the receptor domains of that host cell, which are recognized by the outer membrane proteins A (OmpA) of rickettsia -like organism [ 34 ]. The OmpA has previously been described as putative adhesin favoring Rickettsia attachment to epithelial cells in vitro [ 35 ].…”
