The authors relate the results of examining 92 patients with acute pneumococcal pneumonia (APP). The bacteriological methods of studying the tracheal contents and pleural exudate, performed before treatment turned out highly informative. As regards the course of APP, the bacteremic , classic (infiltrative) and pleurisy-complicated varieties were distinguished. It was established that the bacteremic variety of APP may be accompanied by bactericidal shock eventuating in a lethal outcome which is not observed in other varieties. 19.6% of patients with APP demonstrated abacterial fever and 27.1% severe pleuropulmonary complications. The development of the latter ones is predictable according to the presence of pleurisy and fever lasting over 5 days. An opinion is advanced that the continuance of antibacterial therapy over 5 days is not desirable whatever the APP variety.

Background: Purulent meningitis poses a significant clinical challenge with high mortality. We present the case of a 54-year-old female transferred to our emergency department with suspected bacterial meningitis, later diagnosed as an Austrian syndrome.
Case Presentation: The patient exhibited subacute somnolence, severe headache, nausea and fever.

Pneumococcal pneumonia is one of the most common causes of severe pneumonia and pneumonia-related mortality globally. It ranked among the leading causes of morbidity and mortality in children under five years in Ethiopia. Vaccination reduces the burden of pneumonia and pneumococcal infections in both children and adults.

Aim: Community-acquired pneumonia (CAP) significantly contributes to high infant mortality in Kazakhstan and developing effective treatment methods is critical. The aim of this study was to explore the microbiological and immunological characteristics of CAP in vaccinated and unvaccinated paediatric patients.
Methods: The study was carried out in the Regional Children's Clinical Hospital and the research centre of Karaganda Medical University, Republic of Kazakhstan.

Streptococcus pneumoniae (SPN) is a significant pathogen causing pneumonia and meningitis, particularly in vulnerable populations like children and the elderly. Available pneumonia vaccines have limitations since they only cover particular serotypes and have high production costs. The emergence of antibiotic-resistant SPN strains further underscores the need for a new, cost-effective, broad-spectrum vaccine.

Purpose: In the setting of an established childhood pneumococcal vaccination programme with immediate initiation and treatment of antiretroviral therapy (ART) for people living with HIV (PLWH), the risk of adult pneumococcal community-acquired pneumonia (CAP) is not recently described. We aimed to investigate CAP incidence, recurrence, mortality, risk factors and microbiology before and during the COVID-19 pandemic.
Participants: Adults aged ≥18 years were enrolled in three South African provinces from March 2019 to October 2021, with a brief halt during the initial COVID-19 lockdown.
