Complete mitochondrial genome and the phylogenetic position of the blackspotted catshark (Carcharhiniformes: Scyliorhinidae).

In this study, the mitogenome of the blackspotted catshark was first determined. This circle molecular was rich in A (30.7%)+T (30.

[Effects of three antigens extracted from Vibrio vulnificus on the immunological protection of Nibea albiflora].

Nibea albiflora was immunized by intraperitoneal injection with either Lipopolysaccharide (LPS) or outer membrane protein (OMP) extracted from Vibrio vulnificus or formalin killed Vibrio vulnificus (FKC). The influence of the three antigens on the immunological function of Nibea albiflora was determined at different time points following the injection by testing the agglutinating antibody titers of the serum, lysozyme activity of the serum, phagocytic activity of the blood and the relative survival percentage. The results showed that the three antigens have higher immunogenicity and antigenicity than the control group(injection with sterile saline).

[Identification of a Vibrio splendidus strain isolated from ill Sciaenops ocellatus].

Objective: We isolated bacterial strain named M-1 from ill Sciaenops ocellatus with ulceration, and further analyzed the phylogenetics of the bacterial strain.

Methods: We characterized the strain on the basis of its morphology, physiology, and sequence comparison of 16SrRNA and HSP60 genes.

Results: Strain M-1 was identified as Vibrio splendidus.
