Methodology: In this study, we assessed the antibacterial susceptibility of these pathogens causing respiratory tract infections in Dakar, Senegal, during 2007-2008.\u00a0 A total of 290 bacterial isolates (75 H. influenzae, 10 M. catarrhalis, 105 S. pneumoniae, and 100 S. pyogenes) were collected.\u00a0 Results and Conclusions: All H. influenzae isolates were susceptible to amoxicillin\/clavulanic acid, ofloxacin, clarithromycin, cephalosporins, and macrolides.\u00a0 Overall, 26.7% of H. influenzae isolates were completely resistant to ampicillin.\u00a0 Among the M. catarrhalis isolates, 30% were resistant to ampicillin.\u00a0 All the isolates of H. influenzae and M. catarrhalis that were resistant to ampicillin were beta-lactamase producing strains.\u00a0 Among the S. pneumoniae isolates, 33.3% isolates exhibited intermediate susceptibility to penicillin G, and one isolate was completely resistant.\u00a0 All five isolates that were resistant to erythromycin expressed the M phenotype.\u00a0 S. pyogenes exhibited high susceptibility to all other antibiotics, except tetracycline.\u00a0 Our study suggests that except for M. catarrhalis, all other bacterial isolates are susceptible to cephalosporins, macrolides, and fluroquinolones.\u00a0 <\/jats:p>","DOI":"10.3855\/jidc.20","type":"journal-article","created":{"date-parts":[[2009,10,27]],"date-time":"2009-10-27T05:12:32Z","timestamp":1256620352000},"page":"660-666","source":"Crossref","is-referenced-by-count":9,"title":["Antimicrobial susceptibility of select respiratory tract pathogens in Dakar, Senegal"],"prefix":"10.3855","volume":"3","author":[{"given":"Aissatou Geuye","family":"Ndiaye","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheikh Saadbou","family":"Boye","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edwige","family":"Hounkponou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatou Bintou","family":"Gueye","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aida","family":"Badiane","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2222","published-online":{"date-parts":[[2009,10,22]]},"container-title":["The Journal of Infection in Developing Countries"],"original-title":[],"link":[{"URL":"https:\/\/www.jidc.org\/index.php\/journal\/article\/download\/19858566\/298","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.jidc.org\/index.php\/journal\/article\/download\/19858566\/298","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,7,24]],"date-time":"2019-07-24T00:24:52Z","timestamp":1563927892000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.jidc.org\/index.php\/journal\/article\/view\/19858566"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,10,22]]},"references-count":0,"journal-issue":{"issue":"09","published-online":{"date-parts":[[2009,10,27]]}},"URL":"https:\/\/doi.org\/10.3855\/jidc.20","relation":{},"ISSN":["1972-2680"],"issn-type":[{"value":"1972-2680","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,10,22]]}}}
