Cefazolin had activity equivalent to cephalothin against\n            <jats:italic>Streptococcus pneumoniae, Staphylococcus aureus<\/jats:italic>\n            , group A streptococci, and\n            <jats:italic>Proteus mirabilis<\/jats:italic>\n            . Cefazolin was four- to eightfold more active against\n            <jats:italic>Escherichia coli<\/jats:italic>\n            and slightly more active against\n            <jats:italic>Klebsiella pneumoniae<\/jats:italic>\n            , whereas cephalothin was slightly more active against indole-positive\n            <jats:italic>Proteus<\/jats:italic>\n            species. After a 500-mg dose of cefazolin intramuscularly, peak concentrations in the serum were high enough to inhibit all strains of\n            <jats:italic>S. pneumoniae, S. aureus<\/jats:italic>\n            , group A streptococci,\n            <jats:italic>E. coli, K. pneumoniae<\/jats:italic>\n            , and\n            <jats:italic>P. mirabilis<\/jats:italic>\n            , as well as 60% of strains of\n            <jats:italic>Proteus<\/jats:italic>\n            species other than\n            <jats:italic>P. mirabilis<\/jats:italic>\n            . All of 26 patients (18 with pneumonia, 6 with urinary tract infection, and 2 with skin infections) responded clinically and bacteriologically to cefazolin therapy. There were no major side effects of therapy, and no patient complained of pain at the site of intramuscular injection. Cefazolin is an effective cephalosporin which can be used intramuscularly for therapy of serious bacterial infections. Its major advantages over other cephalosporins are higher, more sustained concentrations in the blood and apparent lack of pain on intramuscular injection.\n          <\/jats:p>","DOI":"10.1128\/aac.3.2.168","type":"journal-article","created":{"date-parts":[[2012,6,27]],"date-time":"2012-06-27T23:57:02Z","timestamp":1340841422000},"page":"168-174","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":45,"title":["Clinical and In Vitro Evaluation of Cefazolin, a New Cephalosporin Antibiotic"],"prefix":"10.1128","volume":"3","author":[{"given":"Kristen","family":"Ries","sequence":"first","affiliation":[{"name":"Department of Medicine, Division of Infectious Diseases, Medical College of Pennsylvania 19129"},{"name":"Veterans Administration Hospital, Philadelphia, Pennsylvania 19104"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew E.","family":"Levison","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Infectious Diseases, Medical College of Pennsylvania 19129"},{"name":"Veterans Administration Hospital, Philadelphia, Pennsylvania 19104"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donald","family":"Kaye","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Infectious Diseases, Medical College of Pennsylvania 19129"},{"name":"Veterans Administration Hospital, Philadelphia, Pennsylvania 19104"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","container-title":["Antimicrobial Agents and Chemotherapy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.asm.org\/doi\/pdf\/10.1128\/AAC.3.2.168","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.asm.org\/doi\/pdf\/10.1128\/AAC.3.2.168","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,2,21]],"date-time":"2022-02-21T23:09:21Z","timestamp":1645484961000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.asm.org\/doi\/10.1128\/AAC.3.2.168"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1973,2]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1973,2]]}},"alternative-id":["10.1128\/AAC.3.2.168"],"URL":"https:\/\/doi.org\/10.1128\/aac.3.2.168","relation":{},"ISSN":["0066-4804","1098-6596"],"issn-type":[{"value":"0066-4804","type":"print"},{"value":"1098-6596","type":"electronic"}],"subject":[],"published":{"date-parts":[[1973,2]]},"assertion":[{"value":"1973-02-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
