Description

Outer membrane proteins (OMP) of the marine fish pathogen, Vibrio (Listonella) anguillarum, were examined in a wild type strain and an oxytetracycline (OTC) resistant strain. When the OTC resistant strain was cultured in the presence of OTC, the concentration of a major porin, Omp35La, decreased whereas the concentration of an unknown 26kDa OMP increased. The latter OMP was designated Omp26La. The change in the expression of Omp35La and Omp26La was unaffected by treatment with tetracycline, chlorotetracycline, maltose, rafinose and glucose. Additionally, heat shock treatment did not affect the OMP profiles. Although whether the regulation of both OMPs correlates or not is unclear, it is suggested that OTC specifically affected the expression of both OMPs in the OTC resistant strain. The nucleotide and deduced amino acid sequences of Omp26La were similar to the known OMP (OmpV) of Vibrio cholarae. From the amino acid composition and hydropathy profile, Omp26La was found to have a similar structure to porins such as OmpC and OmpF of E. coll.
