Aquaculture is a fast growing industry with its development hampered by bacterial diseases. Vibriosis caused Harveyi clade strains known for causing heavy loss especially in shrimp aquaculture farms. For farm treatment and pathogen spread management, veterinarians researchers need reliable identification tools. A range of methods have been presented Vibrio spp. recent literature but little feed...

Flagellums have been reported to play a critical role in the protective immunity in host. In clostridia genera it is coded by flagellin (fliC) gene. Previous southern blot analysis has suggested that Flic gene may has two copies in genome of C. chauvoei. We studied sequences of two copies (fliA and fliB) of flagellin gene in Iranian isolates. In this study, four specific primers for fliA, fliB ...

In silico tools are employed to examine the evolutionary relationship to possible vaccine peptide candidates' development. This perspective sheds light on the proteomic changes affecting the creation of HLA specific T-cell stimulating peptide vaccines for HIV. Full-length sequences of the envelope protein of the HIV subtypes A, B, C and D were obtained through the NCBI Protein database were ali...

A gene probe, CAP-21, which demonstrated interrelationships between the members of the Mycoplusma mycoides cluster w a s developed. The probe easily differentiated mycoplasmas in this cluster by clear and predictable hybridization patterns in Southern blots and separated the cluster into four groups. Strains of M. mycoides subsp, mycoides which were capable of causing contagious bovine pleuropn...

The cytochrome B gene (MTCYB) within the mitochondrial genome has been widely used in species identification and taxonomic research. In this study, the population variation of the MTCYB gene in humans was demonstrated. The sequence polymorphism of the MTCYB gene was determined in 417 subjects in 8 populations in Taiwan (Taiwan Chinese, mainland Chinese, Filipino, Thai, Vietnamese, and Caucasian...

The asteroidal sperm-activating peptides (asterosaps) from the egg jelly bind to their sperm receptor, a membrane-bound guanylate cyclase, on the tail to activate sperm in sea stars. Asterosaps are produced as single peptides and then cleaved into shorter peptides. Sperm activation is followed by the acrosome reaction, which is subfamily specific. In order to investigate the molecular details o...

To clarify the phylogenic relationship of channel catfish with other fishes, the cytochrome b (Cyt b) gene of the catfish was cloned and sequenced. Channel catfish (Ictalurus punctatus) belonging to the family Ictaluridae in the order Siluriformes showed a 78.4-87.4% similarity to all but one fish of the family Cyprinidae and river loach Crossostoma lacustre of the family Balitoridae in the ord...
