Congenital Cytomegalovirus Infection Diagnosed Via Dried Blood Spots

Cytomegalovirus is the leading cause of congenital infection (cCMV) affecting up to 0.8% of newborns in high-income countries and is the most common cause of non-genetic deafness in childhood. A wide range of diseases diagnosed either at birth or in childhood, has been correlated to cCMV infection. More...

Carbapenem-Resistant K. Pneumoniae Driven by Nosocomial Spread

Public health interventions to control the current epidemic of carbapenem-resistant Klebsiella pneumoniae rely on a comprehensive understanding of its emergence and spread over a wide range of geographical scales. More...

Direct Molecular Assay Developed for Zika Diagnosis

Zika virus (ZIKV), a mosquito-borne Flavivirus, is a positive single-stranded RNA virus with a nucleic acid length of about 10.7kb. This virus has been spreading rapidly and there have been large-scale outbreaks worldwide in recent years. ZIKV has drawn attention as it may cause severe symptoms while no specific medical treatment or vaccine is currently available. More...

Serum Siderocalin Measured in Patients with TB and HIV

Tuberculosis (TB) continues to be a significant cause of morbidity and mortality worldwide. The progression from uninfected or latently infected to active TB is often insidious and has minimal symptoms in the initial months, resulting in delayed diagnosis and poor outcomes. More...

Hematology Analyzer Screens for Malaria in Clinical Setting

Malaria is a vector-borne infectious disease that continues to have high morbidity and mortality globally. Diagnosis based only on clinical symptoms has very low specificity as there is no combination of symptoms that reliably distinguishes malaria from other causes of fever or influenza. More...

Allergy Risk Increased by Compound Found in Infant Gut

Gut microbiota (formerly called gut flora) is the name given today to the microbe population living in our intestine. A recent study of newborn infants has identified a compound produced by gut bacteria that appears to predispose certain infants to allergies and asthma later in life. More...

Cost-Effectiveness of Media for Melioidosis Diagnosis Reviewed

Melioidosis is a frequently fatal disease caused by a soil bacterium called Burkholderia pseudomallei that is widespread in the rural tropics. The yield of B. pseudomallei from sites with a normal flora is increased by culture using selective, differential media such as Ashdown’s agar and selective broth. More...
