[Pneumonia due to silent aspiration: a diagnostic and therapeutic challenge].

Aspiration pneumonia (AP) may present as gross aspiration of large gastric contents or as a consequence of silent aspiration of contaminated oropharyngeal secretions.AP due to silent aspiration is caused by dysphagia and, in some instances, impaired cough reflex. Factors favouring the development of pneumonia include advanced age as well as severe comorbidity and impaired functional status.

Pneumococcal vaccines for prevention of adult pneumonia.

Streptococcus pneumoniae, pneumococcus, is one of most important bacterial pathogens in adult community-acquired pneumonia. Although it can cause a variety of illness including invasive diseases (IPD), pneumonia has a greater impact than IPD from the perspective of health economics. 23 valent pneumococcal polysaccharide vaccine (PPSV23) and 13 valent pneumococcal conjugate vaccine (PCV13) have been recommended for people ≥65 years old until recently based on evidence in preventing IPD and pneumonia.

Emergence of -bearing MDR-hypervirulent ST307.

We report for the first time whole-genome sequencing of four multidrug-resistant sequence type (ST) 307 recovered from patients in two hospitals in Armenia.
