Protection Against Invasive Infections in Children Caused by Encapsulated Bacteria.

Front Immunol 2018 20;9:2674. Epub 2018 Nov 20.

Vaccine Evaluation Center, BC Children's Hospital Research Institute, Vancouver, BC, Canada.

The encapsulated bacteria , and (Group B Streptococcus) have been responsible for the majority of severe infections in children for decades, specifically bacteremia and meningitis. Isolates which cause invasive disease are usually surrounded by a polysaccharide capsule, which is a major virulence factor and the key antigen in protective protein-polysaccharide conjugate vaccines. Protection against these bacteria is largely mediated via polysaccharide-specific antibody and complement, although the contribution of these and other components, and the precise mechanisms, vary between species and include opsonophagocytosis and complement-dependent bacteriolysis.

[Optimization of real-time multiplex polymerase chain reaction for the diagnosis of acute bacterial meningitis and Neisseria meningitidis serogrouping].

Mikrobiyol Bul 2018 Jul;52(3):221-232

Yıldırım Beyazıt University Faculty of Medicine, Department of Medical Microbiology, Ankara, Turkey.

Streptococcus pneumoniae, Neisseria meningitidis and Haemophilus influenzae type B are responsible for about 80-85% of acute bacterial meningitis cases among adults and in our country it is mandatory to report bacterial meningitis cases caused by these agents. In recent years, disease control programs have focused especially on these three pathogens in our country. It is very important to know the causative agent of meningitis for prevention/control measures, choice of treatment regimen, and prediction of the severity and the course of the disease. Read More

Mechanisms of Blood Brain Barrier Disruption by Different Types of Bacteria, and Bacterial-Host Interactions Facilitate the Bacterial Pathogen Invading the Brain.

Cell Mol Neurobiol 2018 Oct 16;38(7):1349-1368. Epub 2018 Aug 16.

Department of Biomedical Science, Faculty of Medicine and Health Sciences, Universiti Putra Malaysia, 43400 UPM, Serdang, Selangor, Malaysia.

This review aims to elucidate the different mechanisms of blood brain barrier (BBB) disruption that may occur due to invasion by different types of bacteria, as well as to show the bacteria-host interactions that assist the bacterial pathogen in invading the brain. For example, platelet-activating factor receptor (PAFR) is responsible for brain invasion during the adhesion of pneumococci to brain endothelial cells, which might lead to brain invasion. Additionally, the major adhesin of the pneumococcal pilus-1, RrgA is able to bind the BBB endothelial receptors: polymeric immunoglobulin receptor (pIgR) and platelet endothelial cell adhesion molecule (PECAM-1), thus leading to invasion of the brain.

Diagnosing causes of headache within the postpartum period.

J Obstet Gynaecol 2018 Jul;38(5):728

a Obstetrics Department, Ninewells Hospital, University of Dundee , Dundee , UK.

Background: Headache is one of the most common symptoms following delivery and the underlying cause may be benign or life threatening. Identification of the cause of headache in the postpartum period can be challenging and relies on a comprehensive history and thorough examination, with particular focus on the presence or absence of neurological signs, which may suggest a more serious diagnosis (Nelson-Piercy 2010 ). However, through clinical experience and research, we have noted that post-partum headache is significantly under-recognised and treated (Goldszmidt et al. Read More
