Methods Explored for Gram-Negative Non-Fermentative Bacteria ID

The non-fermentative Gram-negative bacteria are widely distributed in the environment and have become increasingly common isolates in the clinical laboratory. Being ubiquitous in nature, they are often disregarded as contaminants. More...

Immunoassays Compared to Improve Diagnosis of Chagas Disease

Chagas disease (CD), caused by the protozoan Trypanosoma cruzi, is a vector-borne infection of significant public health concern in Latin America, where nearly six million people are infected and 70 million are at risk of infection. More...

PCR Kit Developed for Detection of Q-fever Pathogen

Coxiella burnetii is an obligate intracellular bacterium that causes Q fever in animals and humans. The infection results from inhalation of a spore-like small-cell variant, and from contact with the milk, urine, feces, vaginal mucus or semen of infected animals. More...

Disrupted TGFB Signaling Linked to Increased Cancer-Related Bacteria

Following careful analysis of DNA sequences collected in The Cancer Genome Atlas, researchers have proposed that CEACAM (carcinoembryonic antigen related cell adhesion molecule) proteins disrupt TGFB signaling, which alters the composition of the intestinal microbiome to promote development of colorectal cancer. More...

Stunted Microbiota and Opportunistic Pathogen Colonize C-Section Birth

Immediately after birth, newborn babies experience rapid colonization by microorganisms from their mothers and the surrounding environment. Infants born by Caesarean section have gut microbiomes that differ from those of infants born vaginally, carrying more hospital-associated opportunistic pathogens. More...
