The Global Meningitis Genome Partnership.

J Infect 2020 Jun 29. Epub 2020 Jun 29.

WHO, Geneva, Switzerland.

Genomic surveillance of bacterial meningitis pathogens is essential for effective disease control globally, enabling identification of emerging and expanding strains and consequent public health interventions. While there has been a rise in the use of whole genome sequencing, this has been driven predominately by a subset of countries with adequate capacity and resources. Global capacity to participate in surveillance needs to be expanded, particularly in low and middle-income countries with high disease burdens. Read More

Value of Broad Range 16S Ribosomal RNA Gene PCR / Sequencing (Br-PCR) of CSF in the Diagnosis of Bacterial Meningitis.

IDCases 2020 16;21:e00826. Epub 2020 May 16.

Department of Neurology, Mayo Clinic, FL, United States.

Bacterial meningitis is a life-threatening condition that requires quick and definitive diagnosis. Bacterial cultures from cerebrospinal fluid (CSF) return with a negative result as treatment with antimicrobials are sometimes started before sampling of CSF can be obtained which makes isolating the causative bacteria challenging. The value of Broad Range 16S Ribosomal RNA Gene Polymerase Chain Reaction / Sequencing of CSF (Br-PCR) can address this problem by amplifying and identifying any bacterial DNA present in a clinical sample.

Am J Trop Med Hyg 2020 May 26. Epub 2020 May 26.

Division of Infectious Diseases and International Health, Department of Medicine, University of Virginia, Charlottesville, Virginia.

Despite the implementation of effective conjugate vaccines against the three main bacterial pathogens that cause meningitis, , type b (Hib), and serogroup A, the burden of meningitis in West Africa remains high. The relative importance of other bacterial, viral, and parasitic pathogens in central nervous system infections is poorly characterized. Cerebrospinal fluid (CSF) specimens were collected from children younger than 5 years with suspected meningitis presenting at pediatric teaching hospitals across West Africa in five countries including Senegal, Ghana, Togo, Nigeria, and Niger.

Protein Oxidation Biomarkers and Myeloperoxidase Activation in Cerebrospinal Fluid in Childhood Bacterial Meningitis.

Antioxidants (Basel) 2019 Oct 1;8(10). Epub 2019 Oct 1.

Health Research Institute La Fe, Avenida Fernando Abril Martorell 106, 46026 Valencia, Spain.

The immunological response in bacterial meningitis (BM) causes the formation of reactive oxygen and nitrogen species (ROS, RNS) and activates myeloperoxidase (MPO), an inflammatory enzyme. Thus, structural oxidative and nitrosative damage to proteins and DNA occurs. We aimed to asses these events in the cerebrospinal fluid (CSF) of pediatric BM patients. Read More
