Streptococcus pneumoniae is a common cause of respiratory tract infections (RTIs). The prevalence of Streptococcus pneumoniae strains with reduced susceptibility to antimicrobial agents has dramatically increased worldwide. Susceptibility to nine antimicrobial agents and serotypes were determined among 1,644 Streptococcus pneumoniae strains isolated from patients with RTIs in the Tohoku district of Japan from October to December every year from 1998 to 2007. The prevalence of penicillin G…

Antibiotic resistance profiles and multidrug resistance patterns of Streptococcus pneumoniae in pediatrics

S pneumoniae isolates showed high resistance to common antibiotics in mainland China, and 46.1% of invasive clinical isolates were multidrug resistant, so it is important to continued monitor the resistance of S pneumoniae when protein conjugate vaccine (PCV13) is coming in mainlandChina.

Penicillin-Resistant trend of Streptococcus pneumoniae in Asia: A systematic review

Investigation of the changing trend of penicillin-resistant S. pneumoniae (PRSP) in Asia over a 20 years period found variations in susceptibility rates among different centers in each country varied widely.

It is demonstrated that AMPs represent the promising new generation antibiotics as standalone therapeutics or in combination with conventional antibiotics.

Nationwide survey of Streptococcus pneumoniae drug resistance in the pediatric field in Japan

The Drug‐Resistant Pathogen Surveillance Group in Pediatric Infectious Disease conducted a nationwide surveillance of S. pneumoniae in 2000–2001, 2004, 2007, 2010 and 2012, and investigated changes in drug resistance.

Serotype Replacement in Adult Pneumococcal Pneumonia after the Introduction of Seven-Valent Pneumococcal Conjugate Vaccines for Children in Japan: a Systematic Literature Review and Pooled Data Analysis.

Serotype replacement occurred in adult cases of pneumococcal pneumonia following vaccination of children with PCV7 in Japan, and nationwide surveillance is warranted to investigate serotype replacement in the post-PCV13 phase.

Update on the clinical utility and optimal use of cefditoren

It is concluded that cefditoren is an adequate option for the treatment of mild-to-moderate community-acquired respiratory infections, especially in geographical areas with a reported prevalence of phenotypes exhibiting nonsusceptibility to common oral antibiotics.

Current Trend in Pneumococcal Serotype Distribution in Asia

Recent insights into the regulation of NK cell function and the T cell-mediated immune system as tumor immune surveillance are summarized, first attempts to exploit NK cell activation to improve immunity to tumors are attempted.



Antimicrobial susceptibility of respiratory tract pathogens in Japan during PROTEKT years 1-5 (1999-2004).

Telithromycin was highly active against all three pathogens examined throughout the study and accounted for the most erythromycin-resistant isolates in each study year.

Changing epidemiology of antimicrobial-resistant Streptococcus pneumoniae in the United States, 2004-2005.

The penicillin-resistant S. pneumoniae population has changed; most isolates are now closely related to 2 Pneumococcal Molecular Epidemiology Network clones that increased in prevalence from 1999-2000 to 2004-2005.

Trends of penicillin and erythromycin resistance among invasive Streptococcus pneumoniae in Europe.

The results indicate that appropriately dosed beta-lactams for empirical therapy are still the treatment of choice, and that macrolides should be used with prudence.

Rapid Increase of Pneumococcal Resistance to β‐Lactam and Other Antibiotics in Isolates from the Respiratory Tract (Nagasaki, Japan: 1975–1994)

The susceptibility of 101 pneumococcal isolates from the respiratory tract during 1991–1994 was examined and compared with the susceptibility of isolates over the period of 1975–1990, suggesting that anti‐pneumococcal antibiotics should be carefully chosen on the basis of susceptibility tests.

Antimicrobial Resistance among Clinical Isolates ofStreptococcus pneumoniae in the United States during 1999–2000, Including a Comparison of Resistance Rates since 1994–1995

Overall, antimicrobial resistance was highest among middle ear fluid and sinus isolates of S. pneumoniae; lowest resistance rates were noted with isolates from cerebrospinal fluid and blood.

The possible introduction and spread of international epidemic clones into Asian countries and the increasing problems of pneumococcal drug resistance in Asian countries for the first time are suggested.

Antibiotic susceptibility according to genotype of penicillin-binding protein and macrolide resistance genes, and serotype of Streptococcus pneumoniae isolates from community-acquired pneumonia in children.

The results suggest that introduction of conjugate vaccines into infants and children is necessary for the prevention of pneumococcal infections in Japan.

Susceptibilities to Levofloxacin in Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis Clinical Isolates from Children: Results from 2000-2001 and 2001-2002 TRUST Studies in the United States

If fluoroquinolones become a treatment option for pediatric patients, careful monitoring of fluoroquolone susceptibilities will be increasingly important in future surveillance studies.

Hospitalized community-acquired pneumonia due to Streptococcus pneumoniae: Has resistance to antibiotics decreased?

A decrease in drug resistance compared with a previous report and a relatively high incidence of serotype 1 pneumococcal CAP is found and a high prevalence of HIV-1 infection among individuals with pneumococal pneumonia is observed.
