RICERCA DI FAGI lN CAMPYLOBACTER TERMOFILI: DATI PRELIMINARI

Eighty Campylobacter jejuni/coli strains were screened for phage by induction with mitomycin C. After treatment of culturès with mitomycin C (1 μg/ml for 18 h), cells were removed by centrifugation and supernatants examined by electron microscopy Phage paiticles were recovered from one strain of C. ieiuni; electron micrographs showed that the phage head is isometric, 53 nm in diameter, and that the sheathed tail is about 113 nm long. The morphological feature of this phage qppears to be simiilar to that described by Rittchie et al. for a phage detected from C. jeiuni isolates.
