The antibacterial effects of 209 Pseudomonas strains isolated from spoiled iced fish and newly caught fish were assessed by screening target organisms in agar diffusion assays. One-third (67 strains) inhibited the growth of one or several of six target organisms (Escherichia coli, Shewanella putrefaciens, Aeromonas sobria, Pseudomonas fluorescens, Listeria monocytogenes, and Staphylococcus aure...

INTRODUCTION Seabirds have been historically used to monitor environmental contamination. The aim of the present study was to test the suitability of a species belonging to the Procellariiformes group, the Manx shearwater, Puffinus puffinus, as a sentinel of environmental health, by determining contaminant levels (trace metals and organochlorine compounds) from carcass tissues and by isolating ...

Aeromonas sobria serine protease (ASP) is an extracellular serine protease secreted by the organism. Here, we identified the amino acid residue of ASP that contributes to substrate specificity by using both synthetic peptides and biological protein components. The results showed that the arginine residue at position 566 (Arg-566) of ASP, which is located in the extra occluding region of ASP clo...

525 vaccine. The vaccine contained formaldehyde detoxified, aluminium adsorbed diphtheria and tetanus toxins, 25 and 75 flocculation units/ml respectively (SBL, Sweden). The subjects were randomised by using sealed envelopes to receive the vaccine subcutaneously (21 subjects) or intracutaneously (18). The mean age was 29-8 (range 23-43) years, with no difference between the groups. Seven of the...
