being the only laboratory in sweden performing cytotoxin-assay from cases of c. difficile enterocolitis during 1979-1981 , we have observed that the frequencies with which clindamycin/lincomycin are associated with c. difficile enterocolitis have decreased from 30 % ( 1979 ) to 9 % ( 1981 ) while the role of cephalosporins has increased from 18 % to 29 % .
