Fifty bacterial isolates isolated from dairy product, skin and blood from cancer and kidney failure dialysis patients were identified to twenty two species and the following genera:- Brevibacterium, Corynebacterium, Arthrobacter, Actinomyces, Exiguobacterium, Kocuria, Micrococcus, Rothia, Rhodococcus using a set of phenetic characteristics. Twelve isolates of the different species from the genera Brevibacterium, Arthrobacter, Corynebacterium, Kocuria, Rhodococcus, Rothia were selected and probed for lin gene by polymerase chain reaction. One species Kocuria rhizophila which inhibited most of the tested organisms did not have lin gene in the chromosome, while, the species Corynebacterium glucuronolyticum, Arthrobacter comminsii, Arthrobacter oxydans have the lin gene. Our results found there wide distribution of the structural gene encoding this linocin M18 within coryneform bacteria and also in the genus Kocuria.
