“…Neither donor nor recipient cell filtrates had an effect on plasmid transfer by conjugation among Bacillus strains (4), differentiating this mating process from that observed among some streptococci (6). In our experiments mating ability was monitored indirectly by measuring the transmission of the selectable plasmid pBC16.…”

“…We do not regard the discovery of homologous replicons in Staphylococcus, Streptococcus, and Bacillus species as very surprising in itself, since these genera have long been recognized to include members with natural mechanisms for efficient uptake of and transformation by both chromosomal and plasmid DNAs (9,12,17,19,20,27,28). Recent reports of conjugative plasmids in these bacteria that transfer across genus barriers, as well as species barriers (4,10,16,23), further strengthen the conclusion that intergeneric exchange of genetic material in their natural environments must be relatively common among them. We were surprised, however, by the very high degree of sequence homology between pBC16 and pAMalAl apparent in their restriction fragment fingerprints.…”

“…1988). Στα ί δια περίπου επίπεδα κυμαίνονται και τα μεγέθη των συζευκτικών R πλασμιδίων των στρεπτόκοκκων, τα οποία όμως φέρουν γονίδια ανθεκτικότητας στην τετρακυκλίνη, καναμυκίνη, στρεπτομυκίνη, ερυθρομυκίνη και λινκομυκίνη (LeBlanc 1981. Clewell 1981.…”

“…Αυτό κω δικοποιεί τρεις πρωτεΐνες: Την τρανσποζάση που είναι υπεύθυνη για τη μετατό πιση του Τη3, την ρεσολβάση που είναι απαραίτητη για την ενσωμάτωση του σε συγκεκριμένη θέση και την β-λακταμάση τύπου ΤΕΜ-1 που καθορίζει την ανθεκτι κότητα στις πενικιλλίνες. Το πρότυπο που προτάθηκε από τον Clewell (1981) δέ χεται ότι τα τρανσποζόνια, αφού αποκοπούν από το χρωματόσωμα, έχουν τρείς επιλογές: α) να επανέλθουν στο χρωματόσωμα, β) να παρεμβληθούν σε ένα πλασμίδιο ή γ) να μεταβιβαστούν με σύζευξη σε άλλο βακτήριο.…”
