Facklamia species are Gram-positive, facultatively anaerobic bacteria that present a challenge for clinical labs to identify. It's α-hemolytic, catalase negative and is often misidentified as ...

Gram-positive bacteria have thick cell walls. A Gram stain test, which involves a chemical dye, stains the bacterium’s cell wall purple. On the other hand, gram-negative bacteria stain pink instead.

The most prevalent type of gram-positive bacteria found was coagulase-negative staphylococcus, making up about 40 percent of the cases. This was followed by Streptococcus viridans (12 percent ...

More than good or bad bacteria, researchers have now unveiled that positive and negative bacterium are responsible for periodontitis symptoms - Gram-positive and Gram-negative, that is.

Nineteen of the 56 patients had bacteremia from viridans streptococcus ... acute respiratory distress accompanied by a blood culture positive for S. mitis. She was admitted to the intensive ...

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 ...

The following information was assessed: number of presumed and culture-positive endophthalmitis cases, source of infection, microbiological result (aqueous and/or vitreous culture and Gram ...

The present report deals with the in vitro anti-microbial activity of novobiocin and its efficacy in the treatment of a variety of surgical infections due to staphylococci and other gram-positive ...
