therapy for experimental intraabdominal sepsis: comparison of four cephalosporins with clindamycin plus gentamicin.	an experimental model of intraabdominal sepsis in rats was used for evaluation of treatment with four cephalosporins: cephalothin, cefazolin, cefoxitin, and cefamandole. doses were 115 mg of each of the cephalosporins/kg and, in additional experiments, 350 mg of cephalothin or cefazolin/kg. response to treatment was evaluated by mortality rate and the incidence of intraabdominal abscess. all four cephalosporins and gentamicin produced a similar reduction in mortality rates. there was a marked va ...	1977	321707
resistance to gentamicin: a growing concern.	gentaminic was introduced in 1969 as a broad-spectrum aminoglycoside effective in vitro against a majority of aerobic gram-negative bacilli. in recent years gentamicin-resistant clinical isolates have become more prevalent. in our laboratory in 1975, 32% of pseudomonas sp and 44% of indole-negative proteus sp isolates were resistant to gentamicin. resistance to tobramycin is also increasing; 24% of escherichia coli and 28% of indole-negative proteus sp isolates were found to be tobramycin-resist ...	1977	322294
esculin hydrolysis by enterobacteriaceae.	literature reports disagree concerning esculin hydrolysis in the family enterobacteriaceae. a total of 2,490 strains of the family were investigated for esculin hydrolysis by two methods, the esculin spot test and the pathotec incubation strip, which measures constitutive enzyme, and five growth-supporting methods, which determine both constitutive and inducible enzymes. the five growth-supporting media studied were: vaughn-levine, the standard esculin hydrolysis medium (p. r. edwards and w. h. ...	1977	330558
unusual enterobacteriaceae. "proteus rettgeri" that "change" into providencia stuartii.	a blood culture bottle from a patient with bacteremia contained both proteus rettgeri biogroup 5 and providencia stuartii (described in bergey's manual of determinative bactiology [8th ed., 1974] as proteus inconstans), which had the same unusual antibiotic resistance pattern. single colonies of this p. rettgeri biogroup 5 isolate were shown to produce urea- clones. if current taxonomy is used, the strain changed from p. rettgeri to p. stuartii in the laboratory and probably also in the patient. ...	1977	334793
