Test Discriminates Between Viral and Bacterial Infections
Lower respiratory tract infection (LRTI) commonly causes hospitalization in adults but because bacterial diagnostic tests are not accurate, antibiotics are frequently prescribed. Antibiotics are lifesaving drugs, but overuse is leading to antibiotic resistance, one of the world's most pressing health threats. More...10 Aug 2017
Methods Compared for Chagas Disease Diagnosis
Chagas Disease (CD) is a chronic infectious disease caused by the protozoan flagellate Trypanosoma cruzi. In endemic countries, CD is transmitted mainly through the contact with feces of different triatomine bugs. Due to increased migration, CD has become an international health problem.

TB Screening Recommended for High-Risk Healthcare Workers Only
Routine screening for and treatment of latent tuberculosis (TB) infection has traditionally been an important part of TB prevention in Canadian and US healthcare institutions, but recent data have called into question its cost effectiveness. A new study has found that the current strategy of annual screening of is ineffectively expensive, suggesting that a switch to screening only high-risk healthcare workers is needed.

New Test Distinguishes Zika from Similar Viral Infections
Zika is a mosquito-borne disease and is linked to severe congenital birth defects. Assays already exist to detect Zika virus infection, but they either work only shortly after infection or are poor at differentiating Zika from other flaviviruses. More...02 Aug 2017
Powassan Virus Diagnosed in Patients with Tick-Borne Diseases
Powassan virus (POWV) lineage II, also known as deer tick virus, is an emerging tick-borne flavivirus transmitted by Ixodes scapularis ticks, which are also the primary vector for the Lyme disease pathogen Borrelia burgdorferi. More...02 Aug 2017
Antimicrobial Therapy Biomarker Enumerates Eosinophil Count Changes
Eosinopenia as a criterion of sepsis has been the subject of debate for decades and the pathophysiology of eosinopenia is related to the migration of eosinophils to the inflammatory site, presumably as a result of chemotactic substances secreted during the acute phase of inflammation. More...01 Aug 2017
Accuracy of Malaria Tests Evaluated for Febrile Children
It remains challenging to distinguish malaria from other fever causing infections, as a positive rapid diagnostic test does not always signify a true active malaria infection. Antigen persistence could increase the rate of false positive test results, leading to a wrong diagnosis in settings where other diagnostic tools are unavailable. More...01 Aug 2017
