| severe group a streptococcal infections associated with a toxic shock-like syndrome and scarlet fever toxin a. | there is concern that group a streptococci, which have caused less serious infections in developed countries in recent decades, may be acquiring greater virulence. we describe 20 patients from the rocky mountain region who had group a streptococcal infections from 1986 to 1988 that were remarkable for the severity of local tissue destruction and life-threatening systemic toxicity. among the 20 patients (median age, 36), necrotizing fasciitis with or without myositis was the most common soft-tiss ... | 1989 | 2659990 |

| molecular characterization of streptococcus pyogenes isolates collected during periods of increased acute rheumatic fever activity in utah. | salt lake city, utah has seen a continuing resurgence of rheumatic fever (rf) since 1985. | 2004 | 14743048 |
| prevalence of chlamydia trachomatis and mycoplasma pneumoniae in children with and without pharyngitis. | the prevalence of chlamydia trachomatis, mycoplasma pneumoniae, group a beta-hemolytic streptococcus, and other treatable organisms was studied in children with and without pharyngitis. children aged 2 to 12 years were evaluated between november 1985 and april 1986 in three family practice offices in the salt lake city area. chlamydia trachomatis was not detected in the pharynx of any of the children studied. mycoplasma pneumoniae was cultured from 5 percent of the 242 children studied, group a ... | 1988 | 3128634 |
| association of 2009 pandemic influenza a (h1n1) infection and increased hospitalization with parapneumonic empyema in children in utah. | during previous influenza pandemics, many deaths were associated with secondary bacterial infection. in april 2009, a previously unknown 2009 influenza a virus (2009 h1n1) emerged, causing a global influenza pandemic. we examined the relationship between circulating 2009 h1n1 and the occurrence of secondary bacterial parapneumonic empyema in children. | 2010 | 20407400 |
| mechanisms of resistance for streptococcus pyogenes in northern utah. | the purpose of this study was to (1) determine the rates of penicillin and erythromycin resistance among streptococcus pyogenes isolates in northern utah, and (2) determine the genotype of the erythromycin resistant strains, thereby providing information regarding the mechanism of the resistance. | 2009 | 19354028 |
| temporal association of the appearance of mucoid strains of streptococcus pyogenes with a continuing high incidence of rheumatic fever in utah. | our objective was to confirm an observed temporal association of increased numbers of rheumatic fever cases concomitant with the appearance of an increased prevalence of mucoid strains of streptococcus pyogenes. during the resurgence of rheumatic fever (rf) that has occurred in the intermountain area surrounding salt lake city, utah, since 1985, the largest number of cases occurred in 1985 and 1986 and 12 years later in 1997 and 1998. during the initial outbreak and the later exacerbation of the ... | 2004 | 14993572 |
| molecular analysis of group a streptococcus type emm18 isolates temporally associated with acute rheumatic fever outbreaks in salt lake city, utah. | acute rheumatic fever (arf) and subsequent rheumatic heart disease are rare but serious sequelae of group a streptococcus (gas) infections in most western countries. salt lake city (slc), utah, and the surrounding intermountain region experienced a resurgence of arf in 1985 which has persisted. the largest numbers of cases were encountered in 1985-1986 and in 1997-1998. organisms with a mucoid colony phenotype when grown on blood agar plates were temporally associated with the higher incidence o ... | 2002 | 11980963 |
