| asymptomatic epidemic acquisition of group a streptococcus: antibody response to extracellular and type-specific antigens. | the antibody response of 40 institutionalized children involved in an epidemic associated with asymptomatic pharyngeal acquisition of a group a, m-11, t-11 typeable streptococcus was studied. titers of antibody to streptolysin o and to deoxyribonuclease b determined in sera collected from patients within two weeks of positive throat cultures were significantly higher than those in sera of controls (p smaller than 0.001). however, there was no rise in antibody titers in sera obtained from these p ... | 1975 | 1099146 |
| value of desiccated swabs for streptococcal epidemiology in the field. | streptococcal surveys in foreign countries or remote areas may be greatly enhanced by the use of calcium alginate swabs desiccated in sterile silica gel. delays of up to 4 weeks before return to a base laboratory are feasible, and the need for fresh media or laboratory facilities in the field may be eliminated. comparison of direct plating on crystal violet blood agar versus delayed silica gel preservation during surveys in uganda, haiti, colombia, and miami, fla., showed no significant loss of ... | 1973 | 4346975 |
| clinical and epidemiologic features of invasive group a streptococcal infections in children. | invasive group a streptococcal infection (igasi) is a disease of public health importance. the clinical epidemiology of igasi in children has not been studied extensively in florida, usa. the objective of this study was to describe the clinical and epidemiologic features of children hospitalized for igasi in florida, usa, during a 4-year period. | 2007 | 17532835 |
| postpartum invasive group a streptococcal disease in the modern era. | to describe the clinical features of individuals hospitalized for postpartum invasive group a streptococcus (gas) infection, a retrospective, population-based study of hospitalized patients in the state of florida was conducted. cases of postpartum invasive gas infection (occurring within 42 days of delivery) were compared to women with other manifestations of invasive gas disease with respect to their age at the time of admission. four cases of postpartum invasive gas infection were detected in ... | 2008 | 19125207 |
| blunt trauma as a risk factor for group a streptococcal necrotizing fasciitis. | anecdotal reports suggest that blunt trauma and seemingly innocuous musculoskeletal injuries (e.g., muscle strains) are risk factors for developing necrotizing fasciitis (nf) and myositis caused by group a streptococcus and other bacteria; however, this hypothesis has not been tested in analytic epidemiologic studies of invasive group a streptococcal (gas) disease. we conducted two case-control studies to determine whether nonpenetrating trauma is a risk factor for either nf or severe cellulitis ... | 2007 | 17697787 |

| invasive group a streptococcal infections in florida. | several previous studies of invasive group a streptococcal (gas) disease have been hindered by small sample sizes (< or = 100 patients) and limited generalizability. | 2003 | 14570340 |

| group a streptococcal antibodies in subjects with or without rheumatic fever in areas with high or low incidences of rheumatic fever. | the levels of streptococcal antibody titers in populations with or without rheumatic fever from an area with a relatively high incidence of rheumatic fever and an area with a low incidence of this disease were compared. streptococcal antibody titers were determined for two populations, each of which included children without rheumatic fever (nonrheumatic children) and rheumatic fever patients. the two populations were derived from two separate geographic areas, one with a high incidence of rheum ... | 2003 | 12965922 |
| invasive group a streptococcal disease and intensive care unit admissions. | to determine the clinical epidemiology of invasive group a streptococcal disease (igasd) and identify predictors of admissions into an intensive care unit (icu). | 2002 | 12447530 |
| a two-center review of bacteremia in the community hospital. | there are fewer studies on bacteremia coming from the community hospital, where the practicing family physician is likely to see this problem, than from the university hospital. the hypothesis of this study was that patterns of bacteremia would be different between the two types of hospitals. two hundred four patient episodes of culture-proven bacteremia from two analogous community hospitals were reviewed. bacteremia was discovered in 2.6 of 1,000 patients, which is lower than reports from univ ... | 1987 | 3546587 |
