Optochin-resistant Streptococcus pneumoniae.
Streptococcus pneumoniae (pneumococcus) remains a major cause of mortality and morbidity at the extremes of age. With increasing antibiotic resistance, its accurate early identification is important for initial management [1]. Its identification in clinical laboratories relies on colony morphology, α-haemolysis on blood agar, and optochin susceptibility. The bile solubility test, although simpl...
متن کاملCharacterization of in vitro-generated and clinical optochin-resistant strains of Streptococcus pneumoniae isolated from Argentina.
Optochin susceptibility is a key test used for pneumococcal diagnosis, but optochin-resistant (Opt(r)) pneumococci have been reported in the last 2 decades. In this work, we characterized eight Opt(r) clinical strains which presented a new mutation, G47V, a predominant A49S mutation (recently reported in Brazil) and A49T. These mutations were found in the c subunit of the F(0)F(1) ATPase encode...
متن کاملEmergence of Optochin Resistance among Streptococcus pneumoniae in Japan
The optochin susceptibility test is a key method for differentiating Streptococcus pneumoniae from other -hemolytic streptococci; however, optochin-resistant (Opt) S. pneumoniae have been reported in the last two decades. In this study, we investigated the isolation frequency of Opt S. pneumoniae in the North Kyushu area of Japan, and biochemically and genetically characterized Opt S. pneumoni...
متن کاملDrug-resistant Streptococcus pneumoniae.
Streptococcus pneumoniae remains a major cause of infection in both children and adults, annually resulting in significant morbidity and mortality. The past two decades have seen an alarming worldwide increase in the incidence of drug-resistant S. pneumoniae (DRSP). DRSP is now common throughout the United States, and physicians are questioning how best to approach this epidemic. With the intro...
متن کاملPenicillin-resistant Streptococcus Pneumoniae
Streptococcus pneumoniae is a major cause of pneumonia, meningitis, septicemia, acute otitis media, and other serious infections, severely affecting infants, young children, and the elderly. In the past, S. pneumoniae was uniformly susceptible to penicillin, which remained the drug of choice for serious infections. However, since the mid-1960s, resistance to penicillin, which was first reported...
