Fungi-Fluor® Pneumocystis Kit (for U.S. & outside of Europe orders)Catalog Number 22363
Pneumocystis jiroveci (previously named P. carinii) is an organism that can cause Pneumocystis carinii pneumonia (PCP) in immunocompromised patients. PCP, long associated with morbidity and mortality with HIV-infected (AIDS) patients, is now increasing in prevalence among the non-HIV infected immunosuppressed population. Early detection allows the introduction of appropriate treatment and may improve chances of patient survival. The Fungi Fluor® Pneumocystis kit offers a fast, fluorescent staining procedure for Pneumocystis carinii in bronchial specimens.
Product is for research use only in Europe.
