Pneumonia is the main cause of children mortality worldwide, and its major treatment obstacle stems from the microorganisms increasing development of resistance to several antibiotics. Photodynamic therapy has been presenting, for the last decades, promising results for some subtypes of cancer and infections. In this work we aimed to develop a safe and efficient in vitro protocol for photodynamic inactivation of Streptococcus pneumoniae, one of the most commonly found bacteria in pneumonia cases, using two near-infrared light sources and indocyanine green, a FDA approved dye...

As children age, they become less susceptible to the diverse microbes causing pneumonia. These microbes are pathobionts that infect the respiratory tract multiple times during childhood, generating immunological memory. To elucidate mechanisms of such naturally acquired immune protection against pneumonia, we modeled a relevant immunological history in mice by infecting their airways with mismatched serotypes of Streptococcus pneumoniae (pneumococcus). Previous pneumococcal infections provided protection against a heterotypic, highly virulent pneumococcus, as evidenced by reduced bacterial burdens and long-term sterilizing immunity...

In Streptococcus pneumoniae, the type 1 pilus is involved in many steps of pathogenesis, including adherence to epithelial cells, mediation of inflammation, escape from macrophages, and the formation of biofilms. The type 1 pilus genes are expressed in a bistable fashion with cells switching between ON and OFF expression states. Bistable expression of these genes is due to their control by RlrA, a positive regulator subject to control by a positive feedback loop. The type 1 pilus genes are also thought to be negatively regulated by a large number of repressors...

BACKGROUND: Routine immunisation with pneumococcal conjugate vaccines (PCV7/10/13) has reduced invasive pneumococcal disease (IPD) due to vaccine serotypes significantly. However, an increase in disease due to non-vaccine types, or serotype replacement, has been observed. Serotypes' individual contributions to IPD play a critical role in determining the overall effects of PCVs. This study examines the distribution of pneumococcal serotypes in children to identify leading serotypes associated with IPD post-PCV introduction...

BACKGROUND: Once a well-recognized entity, occult bacteremia (OB) is no longer a significant or serious bacterial infection. First following the introduction of the Haemophilus influenzae type B vaccine and now with the implementation of the conjugate pneumococcal vaccine (PCV), the number of cases has declined significantly. This has led to a change in many published guidelines to avoid taking blood cultures in fully vaccinated children presenting with fever. In Israel, the introduction of the PCV13 is now widespread...

BACKGROUND: Pneumonia causes an enormous burden of childhood disease globally, particularly in low- and middle-income countries. Pneumococcus is the most common bacterial aetiology of pneumonia; however, antimicrobials are limited and may not adequately address the local epidemiology of the region. AIM: To undertake a review and meta-analysis of pneumonia studies in sub-Saharan Africa to evaluate antimicrobial susceptibility patterns in childhood pneumonia. METHODS: Articles published in PubMed and Google between 2006 and 2016 which evaluated antimicrobial susceptibility profiles of pneumococcal pneumonia in children in sub-Saharan Africa were identified...

Antibiotic use not only selects for resistance in pathogenic bacteria, but also in commensal flora of exposed individuals. Little is known epidemiologically about antibiotic resistance in relation to people with HIV infection in sub-Saharan Africa. This study investigated the carriage of antibiotic resistant bacteria among HIV infected children at a tertiary hospital in Ghana. One hundred and eighteen HIV positive children were recruited at the Korle-Bu Teaching Hospital in Ghana and nasopharyngeal specimens were collected from them...

The aim of this retrospective study was to review the diagnostic accuracy of real-time polymerase chain reaction (PCR) testing of cerebrospinal fluid (CSF) samples for Streptococcus pneumoniae DNA in comparison with traditional bacterial culture. The hypothesis was that PCR is more sensitive than culture and would detect more cases of pneumococcal meningitis, particularly in children treated with antimicrobials before CSF sampling occurred. Patients younger than 16 years who had a CSF sample tested for S.pneumoniae DNA by PCR between 2004 and 2015 were included...
