    Abstract: The effects of air exposure on the antioxidant capacity of marine gastropod, Babylonia areolata, were evaluated. Superoxide dismutase (SOD) activity, malondialdehyde (MDA) content, and total antioxidant capacity (T-AOC) levels in the muscle and hepatopancreas in B. areolata were measured after air exposure and re-submersion. Results showed that SOD activity minimally increased in the hepatopancreas and muscle, after air exposure for 4h. SOD activity in the hepatopancreas was lower than the normal level after 20 h of air exposure and air exposure followed by 4 h of re-submersion. T-AOC levels in the hepatopancreas and muscle of B. areolata decreased significantly (P 〈 0.05) following the period of air exposure. MDA content in the hepatopancreas of B. areolata subjected to air exposure for 24 and 28 h was significantly higher than the normal level. SOD activity in the hepatopancreas and T- AOC level in the hepatopancreas and muscle of B. areolata recovered to the normal level after 12 h of air exposure followed by 8 h of re-submersion. Air exposure can cause oxidative damage to B. areolata. The antioxidative system can be restored after air exposure for less than 12 h followed by re-submersion for 8 h.

    Abstract: Streptococcus agalactiae (GBS) is an important Gram-positive pathogen of fish aquaculture worldwide. In this study, we performed a comparative analysis of GBS S03 (serotype III) and S07 (serotype Ia) isolated from Schizothorax spp.. We explored the association between phenotypic antibiotic resistance, virulence, and genomic characteristics. Antimicrobial sensitivity tests on 12 common antibiotics using the disc diffusion method revealed that the GBS S03 resisted seven antibiotics, while GBS S07 showed sensitivity to eleven antibiotics. Pathogenicity analysis demonstrated greater virulence of GBS S07 than S03. Then, the occurrence of antibiotic resistance and virulence genes were identified using the whole-genome sequence (WGS) of GBS S03 and GBS S07. Besides just GBS S03 had gyrA and parC gene mutations, there were mefE , tetO , lnuB , lsaE , APH3’ , and sat-4 resistance genes present only in GBS S03 genome. In addition to 51 virulence genes in both GBS S03 and S07 genomes, GBS S07 carried virulence genes associated with invasion, such as SAN_1519 , rfbA and cylE genes. There was complete concordance between genotypic evidence and phenotypic characteristics. Virulence factors and phylogenetic analysis showed that GBS S03 and human sources shared an extremely close evolutionary relationship. Our findings also provide important proof for using WGS as an effective tool for phenotypic predictions of GBS.
