Rare Infection in Transplant Recipients Linked to Donors

The way in which heart and lung transplant recipients acquired a specific species of bacteria, Mycoplasma hominis, had been previously undefined, and the bacterium was difficult to test for and detect. Originally, this bacterium was considered to reside exclusively in, and be a potential pathogen of the area of the reproductive and urinary organs. More...

Urinary Pathogen Resistance Increased Post Kidney Transplant

A urinary tract infection (UTI) is the most common complication after kidney transplantation and it can cause severe sepsis and transplant loss. Emergence of drug resistance among gram-negative urinary pathogens is the current challenge for urinary tract infection treatment after kidney transplantation. More...

FISH Method Developed for Analyzing Immune Response

Researchers have developed a method to analyze hundreds of thousands of cells at once using FISH-Flow for concurrent detection of mRNA and protein markers in single cells using fluorescence in situ hybridization (FISH) and flow cytometry. The new protocol currently evaluates immune responses and could lead to faster and more accurate diagnoses of illnesses, including tuberculosis (TB) and cancers. More...

Three Methods Evaluated for Malaria Detection

Malaria is a debilitating disease with high morbidity and mortality in Africa, commonly caused by different species of the genus Plasmodium in humans. Misdiagnosis is a major challenge in endemic areas because of other disease complications and technical expertise of the medical laboratory staff. More...
