AI Article Synopsis
- Staphylococcus aureus is a common pathogen that can be found in the respiratory tract, and a study was conducted in Vietnam to explore the risk factors for carrying this bacterium, including its methicillin-resistant form (MRSA).
- The study included 1,016 participants from urban and rural areas of northern Vietnam, revealing an overall S. aureus prevalence of 29.8%, with higher rates among younger individuals and urban dwellers, as well as a link to antibiotic use.
- The research identified age and socio-economic status as significant risk factors for both S. aureus and MRSA carriage, indicating that nasopharyngeal colonization is notably more common in children and more
Article Abstract
Background: Staphylococcus aureus is a common human pathogen that can colonise the respiratory tract and cause infection. Here we investigate the risk factors associated with nasopharyngeal carriage of S. aureus (including methicillin-resistant S. aureus [MRSA]) in Vietnam.
Methods: Between February and June 2012, nasal and pharyngeal swabs for S. aureus culture, and demographic and socioeconomic data were taken from 1016 participants in urban and rural northern Vietnam, who were randomly selected from pre-specified age strata.
Results: Overall S. aureus prevalence was 303/1016 (29.8%; adjusted for age: 33.8%). Carriage in the main cohort was found to be associated with younger age (≤5 years [OR 3.13, CI 1.62-6.03]; 6-12 [OR 6.87, CI 3.95-11.94]; 13-19 [OR 6.47, CI 3.56-11.74]; 20-29 [OR 4.73, CI 2.40-9.31]; 30-59 [OR 1.74, CI 1.04-2.92); with ≥60 as reference), living in an urban area (OR 1.36, CI 1.01-1.83) and antibiotics use (OR 0.69, CI 0.49-0.96). MRSA was detected in 80/1016 (7.9%). Being aged ≤5 years (OR 4.84, CI 1.47-15.97); 6-12 (OR 10.21, CI 3.54-29.50); 20-29 (OR 4.01, CI 1.09-14.77) and wealth (>3/5 wealth index, OR 1.63 CI 1.01-2.62) were significant risk factors for MRSA carriage.
Conclusions: Nasopharyngeal carriage of S. aureus is present in one-third of the Vietnamese population, and is more prevalent among children. Pharyngeal carriage is more common than nasal carriage. Risk factors for S. aureus (including MRSA) carriage are identified in the community.

We describe two cases of uncomplicated pharyngitis caused by hypervirulent Klebsiella pneumoniae (hvKp) in a family, initially in an immunocompetent adolescent, followed by possible household spread resulting in similar presentations in the patient's parent. Genomic analysis confirmed hvKp from the two cases were genetically identical and typed as K2-ST3252. Nasopharyngeal carriage and respiratory secretion/droplet may play an important yet underrecognized role in the transmission of hvKp.

Background: The prevalence of meningococcal carriage and serogroup distribution is crucial for assessing the epidemiology of invasive meningococcal disease, forecasting outbreaks and formulating potential immunization strategies. Following the meningococcal carriage studies conducted in Turkey in 2016 and 2018, we planned to re-evaluate meningococcal carriage in children, adolescents and young adults during the COVID-19 pandemic period.
Methods: In the MENINGO-CARR-3 study, we collected nasopharyngeal samples from 1585 participants 0-24 years of age, across 9 different centers in Turkey.
Background: In settings with low pneumococcal conjugate vaccine (PCV) coverage, multi-age cohort mass campaigns could increase population immunity, and fractional dosing could increase affordability. We aimed to evaluate the effect of mass campaigns on nasopharyngeal pneumococcal carriage of Pneumosil (PCV10) in children aged 1-9 years in Niger.
Methods: In this three-arm, open-label, cluster-randomised trial, 63 clusters of one to four villages in Niger were randomly assigned (3:3:1) using block randomisation to receive campaigns consisting of a single full dose of a 10-valent PCV (Pneumosil), a single one-fifth dose of Pneumosil, or no campaign.

Background: Streptococcus pneumoniae is an important cause of pneumonia, sepsis, and meningitis, which are leading causes of child mortality. Pneumococcal conjugate vaccines (PCVs) protect against disease and nasopharyngeal colonization with vaccine serotypes, reducing transmission to and among unvaccinated individuals. Mozambique introduced 10-valent PCV (PCV10) in 2013.
