Lactococcus garvieae infection in wild wrasse Coris aygula is reported, and the serological and molecular characteristics of the isolate are described. This is the first evidence of the presence of this pathogen in the Red Sea, and it follows the recent diagnosis of Mycobacterium marinum and Streptococcus iniae in wild fish from the same region. Whether all 3 pathogens are strains endemic to th...

The secreted globular head C1q (sghC1q) genes can be characterized as a family of genetic loci encoding signal peptides followed by single complement component 1q globular (gC1q) motifs. Members of this family have been referred to as precerebellin-like (Cblnl), C1q-like or ovary specific C1q-like factors, and are transcribed in response to infection and/or during early development. This study ...

Toll-like receptor (TLR) 3 is an important member of the TLR family, recognizes invading pathogens specifically double-stranded RNA viruses. In this paper, turbot (Scophthalmus maximus) TLR3 gene (smTLR3) was cloned and its expression profiles were analyzed with RT-PCR and In situ hybridization. Then its expression was investigated in cultured peripheral blood leukocytes (PBLs) simulated with p...

Ulva is a commercially important marine macroalga. It hosts both epiphytes and endophytes. The latter are assumed to protect through secondary metabolites. Previously, we demonstrated bioactive endophytes from macroalgae with great potential control diseases of aquaculture. In this study, introduced bacterial endophyte back into its original host ( sp.) survival over time in fresh freeze-dried ...

Streptococcosis is an infectious bacterial disease of both homeotherms and poikilotherms. Among the Streptococcus species that infect marine animals, agalactiae has broadest host spectrum, including different aquatic organisms in freshwater environments. The common dolphin ( Delphinus delphis ) categorized as Endangered Mediterranean Sea. There are few reports a streptococcal infection D . , ca...
