Jacobs, MD, PhD, Case Western Reserve Medical School, reported on a study of serotypes of \u003Cem\u003ES. pneumoniae\u003C\/em\u003E isolated in a University Hospital setting in the United States between January 1997 and December 2005. Vaccine associated types remained relatively constant. The appearance of type 19A increased from \u0026lt;10%\/year in 2002 to 30%\/year by 2005. Drug resistance in type 19A to beta-lactams, azithromycin and clindamycin also increased.\u003C\/p\u003E\n         \u003Cp id=\u0022p-4\u0022\u003EDr. Jacobs also presented evidence showing changes in the serotype distribution and drug resistance patterns of pneumococcal isolates before and after the introduction of PCV7. Serotypes of \u003Cem\u003ES. pneumoniae\u003C\/em\u003E were isolated by the Clinical Microbiology Laboratory of the University Hospitals of Cleveland from January 1997 to December 2005. Of 1,119 strains isolated, 377 (33.7%) were MDR, all were penicillin nonsusceptible; 219 were also resistant to a macrolide and trimethoprim-sulfamethoxazole (SXT). Resistance to clindamycin was seen in 141 MDR isolates.\u003C\/p\u003E\n         \u003Cp id=\u0022p-5\u0022\u003EDr. K.K. Hsu presented an analysis of serotype distribution and antibiotic resistance of invasive pneumococcal disease (IPD) isolates identified via surveillance of microbiology reports of isolates collected from sterile body sites of children \u0026lt;18 years in Massachusetts. Between October 2001 and September 2005, 357 cases of IPD were identified (269 in children \u0026lt;5 years). Serotyping was available for 263 (74%) cases; 61 (23%) were vaccine-type and 202 (77%) were nonvaccine-type. Serotype 19A was the etiology in 58 (22%) cases and progressively increased over the 4 years (10%, 11%, 29%, and 45% of IPD isolates [years 1\u20134 respectively]; p\u0026lt;0.01). No other nonvaccine-type demonstrated a significant increase over this period.\u003C\/p\u003E\n         \u003Cp id=\u0022p-6\u0022\u003EDr. D.J. Farrell presented the year 5 data (2004\u20132005) from the PROTEKT US program, which monitors trends in the prevalence and antibacterial susceptibility of an erm(B)+mef(A) serotype 19A clone, not covered by the current PCV7 pneumococcal vaccine. In year 5, 148 erm(B)+\u003Cem\u003Emef\u003C\/em\u003E(A) serotype 19A isolates were collected from patients aged 0\u20132 years of age. Among these pediatric patients, the erm(B)+\u003Cem\u003Emef\u003C\/em\u003E(A) 19A clone accounted for 21.9% (148\/1440) of all erythromycin-resistant SP isolates collected in year 5, compared with 1.1% (9\/825) in year 1 and 8.5% (60\/710) in year 3. All \u003Cem\u003Eerm\u003C\/em\u003E(B)+\u003Cem\u003Emef\u003C\/em\u003E(A) serotype 19A isolates in year 5 were MDR (resistant to \u22652 antibacterial classes), with high rates of resistance to amoxicillin-clavulanate (83.1%), cefuroxime (100%), erythromycin (100.0%), cotrimoxazole (100%), and tetracycline (100.0%). Resistance to telithromycin was rare (0.7%) and no isolates were levofloxacin resistant.\u003C\/p\u003E\n         \u003Cp id=\u0022p-7\u0022\u003EType 19A has steadily increased in prevalence, as well as in resistance to common drug classes.

Common among patients aged 0\u20132 years, this SP 19A clone exhibits a high degree of MDR, particularly to the P-lactams and the macrolides. Results of the studies presented at the 2006 ICAAC conference in San Diego point to a growing need to include this serotype in future vaccine formulations.\u003C\/p\u003E\n      \u003C\/div\u003E\u003Cul class=\u0022copyright-statement\u0022\u003E\u003Cli class=\u0022fn\u0022 id=\u0022copyright-statement-1\u0022\u003E\u00a9 2006 MD Conference Express\u003C\/li\u003E\u003C\/ul\u003E\u003Cspan class=\u0022highwire-journal-article-marker-end\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Cspan id=\u0022related-urls\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Ca href=\u0022http:\/\/mdc.sagepub.com\/content\/6\/4\/4.abstract\u0022 class=\u0022hw-link hw-link-article-abstract\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EView Summary\u003C\/a\u003E\u003C\/div\u003E  \u003C\/div\u003E\n\n  \n  \u003C\/div\u003E\n\u003C\/div\u003E\n  \u003C\/div\u003E\n\u003C\/div\u003E\n\u003C\/div\u003E\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_figures.js?nzlzcq\u0022\u003E\u003C\/script\u003E\n\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_openurl.js?nzlzcq\u0022\u003E\u003C\/script\u003E\n\u003C\/body\u003E\u003C\/html\u003E"}
