Most species of bacteria can be broadly divided into two groups, known as gram-positive and gram-negative. These categories reflect big differences in the microbes' biology, and they also dictate ...

An antibiotic developed some 80 years ago before being abandoned and forgotten could again offer exciting new solutions, this ...

Elements similar to SaPIs have been detected in related Gram-positive bacteria, prompting a name change to phage-related chromosomal islands (PRCIs). PRCIs are normally quiescent until they are ...

This medium is both selective and differential. The selective ingredients are the bile salts and the dye, crystal violet which inhibit the growth of Gram-positive bacteria. The differential ingredient ...

Researchers have discovered a new cell division pathway in MRSA that enables high-level resistance to β-lactam antibiotics, ...

Gram-negative bacteria, which are more pathogenic, had larger diversity, while the gram-positive bacteria were found more in ...

This electron microscopic image provided by the Centers for Disease Control and prevention depicts two, round-shaped, Gram-positive, Streptococcus pneumoniae bacteria.(AP) Doctors in North Texas say ...

Decades ago, scientists looking for an alternative to animal testing cloned factor C, the horseshoe crab protein that senses ...

anaerobic gram-positive cocci, and Fusobacterium species. The presence of these bacteria is only "normal" if the titer of resident flora is low. When bacterial titers exceed 1000 colony forming ...

2009). This preservative has activity against gram-positive and gram-negative bacteria, including Pseudomonas aeruginosa. It also covers some yeasts and fungi (Maier et al., 2009; Marks et al., ...

Among the bacteria identified were gram-positive cocci, which can lead to skin infections, and antibiotic-resistant gram-negative rods. The study noted that free weights had 362 times more bacteria ...
