In vitro investigation of BK-218, a new oral and parenteral cephalosporin.
نویسندگان
چکیده
The antibacterial activity of BK-218 was similar to that of cefamandole when it was tested against several laboratory strains. The inhibiting effect of BK-218 was greater than that of cephalexin and cefoxitin on penicillin-binding proteins of Escherichia coli HB101. This result was in close correlation with the relative inhibition of radiolabeled glucosamine incorporation (greatest with BK-218) and with the lytic effect (most intensive with BK-218). BK-218 proved to be a good inhibitor for all five of the beta-lactamases that were investigated, although two enzymes (Enterobacter cloacae P99 and Pseudomonas aeruginosa Cilote) hydrolyzed it to some extent.

Background and Objective: Enterohemorrhagic Escherichia coli (EHEC) can cause diarrhea and hemorrhagic colitis in humans. The attachment of EHEC to intestinal epithelial cells is the first step of infection which the protein Intimin plays a key role in this process. An immunogen consisting of Intimin can inhibit the attachment of EHEC and prevent diarrhea. Encapsulation of antigens in particula...
