Garlic contains various nutrients and healthful ingredients. The content of garlic products is closely related to their processing methods, each compound has specific biological effects. Allicin, a heat labile compound, considered the most important factor in garlic. powder commonly prepared by subjecting raw thermal before being grounded into powder,and it interest compare activity with fish. ...

Vibrio cholerae, the agent of cholera, is a normal inhabitant of aquatic environments, in which it survives under a wide range of conditions of pH and salinity. In this work, we identified the nhaA gene in a wild-type epidemic strain of V. cholerae O1. nhaA encodes a protein of 382 amino acids that is very similar to the proteins NhaA of Vibrio parahaemolyticus, Vibrio alginolyticus ( approxima...

The population of Vibrios in diseased Penaeus monodon collected from culture ponds situated at Uran, Maharashtra (west coast of India) was studied. All animals collected were associated with more than one Vibrio species. Bacterial identification based on morphological and biochemical characteristics showed that four groups of Vibrios were present in shrimp hepatopancreas namely Vibrio parahaemo...

The Outer Membrane Protein (OMP) of Vibrio alginolyticus cell wall was administered intramuscularly (IM) to the tiger shrimp (Penaeus monodon Fab.) at 10, 20, 30 μg/kg bw. After 14 days infection, the tiger shrimps were challenged with 10(7) bacterial density of Vibrio harveyi for 24 hours. The total haemocyte count (THC), differential haemocyte count (DHC) and amount of total protein plasma (T...

Interleukin 1β (IL-1β), the first interleukin to be characterized, plays a key role in regulating the immune response. In this study, we determined the cDNA and genomic DNA sequences of the IL-1β gene from the large yellow croaker, Larimichthys crocea. Phylogenetic analysis indicated that the IL-1β (LcIL-1β) gene was most closely related to that of European seabass (Dicentrarchus labrax), shari...

Aquaculture is the fastest growing food sector globally and is established itself as high protein resource to fulfill the food demand since the natural resources exhibits over exploitation. But, presently, the biggest problem faced by the aquaculture industry worldwide is diseases caused due to various biological and non-biological agents. Among the groups of microorganisms that cause serious l...

Secondary metabolites of marine sponge Dendrilla nigra were tested for determining the efficacy of controlling shrimp bacterial pathogens. Based on the exploratory experiments, the chosen dose of D. nigra (500 mg/kg of shrimp) was used for pilot experiment. The percent relative protection (PRP) of shrimps treated with Dendrilla feed and challenged with various concentrations of bacterial pathog...

In torque generation by the bacterial flagellar motor, it has been suggested that electrostatic interactions between charged residues of MotA and FliG at the rotor-stator interface are important. However, the actual role(s) of those charged residues has not yet been clarified. In this study, we systematically made mutants of Vibrio alginolyticus whose charged residues of PomA (MotA homologue) a...

Four motor proteins, MotX, MotY, PomA, and PomB, have been identified as constituents of the Na(+)-driven flagellum of Vibrio species. In this study, the complete motX gene was cloned from Vibrio alginolyticus and shown to complement three mot mutations, motX94, motX115, and motX119, as well as a V. parahaemolyticus motX mutant. The motX94 mutant contains a frameshift at Val86 of MotX, while th...
