The acute phase proteins are biochemically and functionally unrelated protein predominantly synthesized in the liver. The local inflammatory cells i.e. macrophages and neutrophils secretes various cytokines like IL-1, IL-6, IL-8 (interleukins) and TNF-α into bloodstream in response to injury and tissue damage, which stimulate hepatocytes to produce protein and release them into the circulation; these proteins are called as acute phase protein (e.g. C-reactive protein (CRP), serum amyloid A (SAA), metal binding protein, lysozyme, lectin, etc...

Detailed information about patients with infections is required to ensure appropriate choice of treatment. Although white blood cell (WBC) counts, and C-reactive protein (CRP) levels are useful diagnostic indicators of infections, more rapid and easily assayed indicator(s) could improve diagnosis. Moreover, it is of pivotal importance to distinguish bacteria or viruses as causative pathogens. Overall, TLR2 and TLR4 expression levels in neutrophils derived from individuals (n = 118) with bacterial (n = 37) and viral (n = 34) infections were higher than those in control samples (n = 47)...

Structurally diverse glycans are expressed by all animate beings and exert diverse biological functions through specific interactions with glycan binding proteins (GBPs). In humans, glycan-GBP interactions are implicated in many disease-relevant processes in development, infection and immune response to bacterial and viral pathogens. Recent progress in chemical synthesis, including automated glycan assembly, has facilitated access to complex glycans that cannot be isolated from biological material. Glycan immobilization on microarrays allows rapid, multiplexed glycan-GBP interaction studies to reveal biological functions...

Human bocavirus (HBoV) is a parvovirus isolated about a decade ago and found worldwide in both respiratory samples, mainly from early life and children of 6-24 mo of age with acute respiratory infection, and in stool samples, from patients with gastroenteritis. Since then, other viruses related to the first HBoV isolate (HBoV1), namely HBoV2, HBoV3 and HBoV4, have been detected principally in human faeces. HBoVs are small non-enveloped single-stranded DNA viruses of about 5300 nucleotides, consisting of three open reading frames encoding the first two the non-structural protein 1 (NS1) and nuclear phosphoprotein (NP1) and the third the viral capsid proteins 1 and 2 (VP1 and VP2)...

Enterovirus A71 (EV-A71) is one of the main causative agents of hand, foot and mouth disease (HFMD). Unlike other enteroviruses that cause HFMD, EV-A71 is more frequently associated with severe neurological complications and fatality. To date, no effective licensed antivirals are available to combat EV-A71 infection. Little is known about the immunogenicity of viral non-structural proteins in humans. Previous studies have mainly focused on characterization of epitopes of EV-A71 structural proteins by using immunized animal antisera...

New diagnostic platforms often use naso- or oropharyngeal (NP/OP) swabs for pathogen detection for patients hospitalized with community-acquired pneumonia (CAP). We applied multi-pathogen testing to high-quality sputum specimens to determine if more pathogens could be identified relative to NP/OP swabs. Children (<18 years old) and adults hospitalized with CAP were enrolled over 2.5 years through the Etiology of Pneumonia in the Community (EPIC) study. NP/OP specimens with matching high-quality sputum (defined as ≤10 epithelial cells/low power field [lpf] and ≥25 white blood cells/lpf or a q-score definition of 2+) were tested by TaqMan Array Card (TAC), a multi-pathogen real-time polymerase chain reaction (PCR) detection platform...

BACKGROUND AND AIMS: Bacteremia is a common serious manifestation of disease in the intensive care unit (ICU), which requires quick and accurate determinations of pathogens to select the appropriate antibiotic treatment. To overcome the shortcomings of traditional bacterial culture (BC), we have adapted next-generation sequencing (NGS) technology to identify pathogens from cell-free plasma DNA. METHODS: In this study, 78 plasma samples from ICU patients were analyzed by both NGS and BC methods and verified by PCR amplification/Sanger sequencing and ten plasma samples from healthy volunteers were analyzed by NGS as negative controls to define or calibrate the threshold of the NGS methodology...
