'Breath test' shows promise for diagnosing fungal pneumonia

Many different microbes can cause pneumonia, and treatment may be delayed or off target if doctors cannot tell which bug is the culprit. A novel approach—analyzing a patient's breath for key chemical compounds made by the infecting microbe—may help detect invasive aspergillosis, a fungal infecti... Read More

D- Zone Test for phenotypic detection of Inducible clindamycin Resistance

A positive D test indicates that the presence of macrolide-inducible resistance to clindamycin produced by an inducible methylase enzyme that alters the common ribosomal binding site for macrolides, clindamycin and the group B streptogrammins (quinupristin). This cross-resistance, called the ML... Read More
