Biosensor Chips Identify Antibiotic Treatment Faster

Bacterial infections are still a major cause of death in the Western world, and because of over and mistreatment antibiotics resistant bacterial stains are increasing every day. In the UK, it is estimated that 300,000 patients a year acquire infections in hospital, with over 9,000 dying from bacterial infections. More...

Severity Biomarker Found for Leprosy and Leishmaniasis

Visceral leishmaniasis (VL) is a systemic, and most severe form of leishmaniasis and soluble CD163 (sCD163) levels can serve as biomarker for disease severity in several inflammatory disorder, including leprosy. More...

Antigenic Targets Compared for Melioidosis Serodiagnosis

Melioidosis, caused by Burkholderia pseudomallei, is a life-threatening infection endemic in tropical countries and definitive diagnosis of the disease relies upon bacterial culture, which requires suitable laboratory facilities and reliable antibody testing. More...

Lymphocyte Subtyping Proves Useful in Predicting Pneumonia

Pneumocystis jirovecii is an opportunistic fungus that can cause interstitial pneumonia in the immunocompromised host and is associated with a high mortality rate. Antimicrobial prophylaxis reduces the occurrence of P. jirovecii pneumonia (PCP) considerably in susceptible patients. More...

Novel Assay Discriminates Several Aspergillus Species

Invasive aspergillosis (IA) is mainly caused by Aspergillus fumigatus and when diagnosis is made early and first line therapy with voriconazole is initiated promptly, a relatively low mortality is observed. More...
