Microbes Identified In Leukemic Febrile Neutropenia

Despite diagnostic advances in microbiology, the etiology of neutropenic fever remains elusive in most cases. Infectious complications of neutropenia occur in more than 80% of patients who undergo chemotherapy for hematological malignancy and 10% to 50% of those with visceral malignancies. More...

Pneumonia Panel Helps Curb Inappropriate Antibiotic Usage

Pneumonia is swelling (inflammation) of the tissue in one or both lungs. It's usually caused by a bacterial infection or a virus. The symptoms of pneumonia can develop suddenly over 24 to 48 hours, or they may come on more slowly over several days. More...

Multiplex Immunoassays Enable Quantification of Malaria Antigens

The standard of care for malaria diagnosis is blood smear microscopy and antigen detection through rapid diagnostic test (RDT). Microscopy has limitations in terms of difficulty in identifying mixed infections and RDTs are more amenable for the diagnosis of malaria in settings with limited laboratory infrastructure. More...
