Is Enterococcus Gram-positive or negative?

Enterococci are Gram-positive facultative anaerobic cocci in short and medium chains, which cause difficult to treat infections in the nosocomial setting. They are a common cause of UTI, bacteremia, and infective endocarditis and rarely cause intra-abdominal infections and meningitis.

How do you get Proteus bacteria?

How is Proteus mirabilis transmitted? The bacterium spreads mainly through contact with infected persons or contaminated objects and surfaces.
