Plasmid-mediated resistance to gentamicin in Staphylococcus aureus: the involvement of a transposon.

abstract：:Campylobacter-like organisms, isolated from the gastric antrum of Rhesus monkeys, were compared with Campylobacter jejuni and C. pylori. They were similar to C. pylori by light microscopy, in ultrastructural morphology, in enzymic, fatty-acid-methyl-ester, and protein-profile analysis, and in antigenic reactivity with...
