J microbiol biotech - assuredBiol Open 15 March ; 8 3 : bio Anisakis simplex L3 larvae infect fish and other seafood species such as squid or octopi; therefore, humans consuming raw or undercooked fish may become accidental hosts for this parasite. These larvae are induced to enter hypometabolism by cold temperatures. It is assumed that sugars in particular trehalose and glycogen are instrumental for survival under environmental stress conditions. To elucidate the mechanisms of environmental stress response in A. The L3 of A. These results show that trehalose plays a key role in providing energy during the thermotolerance and starvation processes through the molecular and biochemical regulation of trehalose and glycogen metabolism. Anisakis simplex is a parasitic aquatic nematode that colonizes crustaceans, cephalopods, fish and marine mammals.
In recent years, aquaculture of the sea cucumber, Apostichopus japonicus Echinodermata: Holothuroideahas developed rapidly and become an important part of the aquaculture industry in China [ 1 ].
However, j microbiol biotech the rapid expansion of scale, a variety of diseases, for example, a typical skin ulcer syndrome SUShave emerged and hindered the healthy and sustainable aquaculture of A. Vibrio splendidus is one of the most important opportunistic pathogens that can infect A. Thus, http://rectoria.unal.edu.co/uploads/tx_felogin/puritan-writers-the-wonders-of-the-invisible/shining-shakarr.php of the pathogenic metabolic processes of V.
It is well known that iron is a critical element for bacterial growth [ 4 ], intracellular replication [ 5 ], and virulence [ 6 ]. However, the concentration of bio-available iron is usually lower than 10 M, a level far below what is needed for optimal bacterial growth [ 7 ].
Thus, bacteria have evolved several strategies to compete for iron from extremely insoluble ferric oxyhydroxide polymers in the natural environment or from iron-protein complexes such as transferrin or lactoferrin in host tissues [ 89 ]. The most common iron uptake pathways used by bacteria include those involving ferric complexes e.

In previous studies, the iron uptake process had been shown to be associated with the pathogenesis of V. Thus, we wondered whether the infectivity of V. Simple gallium salts such as gallium nitrate [Ga NO 3 3 ] [ 19 ] and gallium maltolate [ 20 ] have been determined to exhibit antibacterial activity, and they represent a new class of anti-infective j microbiol biotech that are different from antibiotics trust definition equity 21 ].
In this study, the effects of Ga NO 3 3 on the growth and iron uptake pathways of V. Since Ga NO 3 3 did not exhibit a strong inhibitory effect j microbiol biotech V. Based on the data obtained, the action mode of Ga NO 3 3 on the growth and the iron uptake of V. The V. Unless otherwise stated, all other chemicals used in this study were purchased from Sangon China.
The ability of V. The here of V. The inhibitory effect of Ga NO 3 3 on V. Cell-free seawater was obtained by filtration through a 0. An overnight culture of V.]
