ABSTRACT
The incidence of vaccine-type Streptococcus pneumoniae carriage and disease have declined in vaccinated children as well as in unvaccinated children and adults. However, diseases caused by non-vaccine type (NVT) S. pneumoniae are increasing. In this study, we report an invasive pneumococcal disease (IPD) caused by NVT multidrug-resistant (MDR) S. pneumoniae transmitted from a vaccinated infant to an unvaccinated healthy woman, and the clinical characteristics of this serotype. A 29-year-old previously healthy woman visited our hospital with fever and headache. She had been breastfeeding her baby for 8 months. She was diagnosed with brain abscess and sinusitis caused by S. pneumoniae. Although the patient had no previous exposure to antibiotics, antibiotic susceptibility test identified the pathogen as MDR. The patient's family members were examined using nasopharyngeal swabs for bacterial culture. The serotype of S. pneumoniae identified from the blood, abscess, and sputum of the patient was 15B/C. After investing the patient's family members, we found that the serotype from nasopharyngeal specimen of her baby was the same. We described an invasive MDR pneumococcal disease in an immunocompetent young adult in the community. IPD likely spread to the patient by close contact with her baby, who harbored S. pneumoniae of NVT. The spread of NVT S. pneumoniae in the post-vaccine era has increased in the community, and resistance pattern for S. pneumoniae of 15B/C changed compared to the pre-pneumococcal conjugate vaccine era. The spread of MDR pathogens causing IPD among family members should be monitored.

We compared the serotypes of Streptococcus pneumoniae between the pre-pneumococcal conjugate vaccine (PCV)13 era and post-PCV13 era among homogenous inhabitants of an isolated South Korean island. A total of 325 S. pneumoniae strains were isolated. In the pre-PCV13 era, 19A/F, 15A/F, 19B, and 23A serotypes were identified. In the post-PCV13 era, 15 serotypes were identified. The 19F and 23A serotypes showed the highest prevalence in the pre- and post-PCV13 era, respectively. After PCV13 introduction, the PCV 13 serotype coverage rate was decreased (80.0% and 30.5% in the pre- and post-PCV13 eras, respectively), while the proportion of non-PCV 13 serotypes increased.
ABSTRACT
OBJECTIVES: This study was conducted to investigate the current status and to suggest future directions for health management of teenagers who use healthy school tuck shops to improve teenagers' eating habits while reducing and preventing obesity. METHODS: A total of 29 students (16 middle school students and 13 high school students) took part in the interview for this study, and the interview was conducted for each school's focus group by using qualitative research methodology. RESULTS: The current status of using healthy school tuck shops and suggested future directions were divided into two categories. Personal barriers such as discrepancies between personal perceptions and behaviors and lack of food choice suitable to individual tastes can be solved by rebuilding the operating system to provide intuitive promotion of behavior and customized products through improvements in existing products and new product development. A lack of consistent management from low utilization convenience and difficulty in maintaining a constant purchase price can be handled by establishing a solution to restricted physical access for products, as well as seeking profit by improving distribution costs via continuous cooperation between the school and community. CONCLUSIONS: Continuous funding and a system that reflects the needs and preferences of healthy school tuck shop users should be applied for sustainable operation of healthy school tuck shops to improve teenagers' eating habits.
