Een unieke verdediging: Bacterie verliest celwand bij aanwezigheid virus
Bacteriën leven tijdelijk zonder hun celwand als er voor hen gevaarlijke virussen in de buurt zijn. Opmerkelijk, want de celwand vormt een stevige barrière tegen dreigingen van buitenaf. Toch is de vondst goed te verklaren én kan het een gevolg hebben voor het bestrijden van ziekteverwekkende bacteriën,…
