Serotype Competence and Penicillin Resistance in Streptococcus pneumoniae
From 2003 to 2005, we prospectively collected 118 isolates of pneumococci belonging to 7 serotypes to investigate their competence under the influence of the synthetic competence-stimulating peptides. The degree of competence of the various serotypes differed significantly. Serotype 6B had the highest competence, followed by serotypes 14, 19F, 9V, 23F, 3, and 18C. Isolates belonging to serotype...
متن کاملImplications of Streptococcus pneumoniae penicillin resistance and serotype distribution in Kuwait for disease treatment and prevention.
Streptococcus pneumoniae causes serious infections. Treatment is difficult because of the emergence of penicillin resistance in S. pneumoniae. Pneumococcal vaccines offer the promise of control and prevention of pneumococcal infections. Serotype prevalence and penicillin susceptibility data for a country will predict the usefulness of the vaccines in that country. In Kuwait, the 23-valent polys...
متن کاملSerotype Prevalence and Penicillin-susceptibility of Streptococcus pneumoniae in Oman
Objectives: to determine the prevalent serotypes of Streptococcus pneumoniae and the rate of penicillin-nonsusceptibility among pneumococci in Oman. Methods: Pneumococcal isolates encountered during the period of September 2002 to December 2007 in the Royal Hospital were serotyped. Clinical information as well as the penicillin susceptibility reports were retrieved from the hospital information...
متن کاملPenicillin resistance and serotype distribution of Streptococcus pneumoniae in Ghanaian children less than six years of age
BACKGROUND The objective of this study was to determine the prevalence of nasopharyngeal carriage, serotype distribution, and penicillin resistance of Streptococcus pneumoniae in children ≤ 6 years of age in Ghana. METHODS A cross-sectional study was carried out on a cluster-randomized sample of children ≤ 6 years of age attending nurseries and kindergartens in Accra and Tamale, Ghana. Basic ...
متن کاملPenicillin resistance and serotyping of Streptococcus pneumoniae in Latin America.
Streptococcus pneumoniae (Strep. pneumoniae) is the main cause of bacterial pneumonia in children less than 5 years of age, with high mortality rates in developing countries. In 1993, the Regional System for Vaccines Group (SIREVA) of the pan-American Health Organisation (PAHO) began a study involving six Latin American countries to identify serotypes and their representativity in the new conju...
