belong to a diverse group of bacteria known as aerobic actinomycetes, characterized as being Gram-positive rods with partially acid-fast, non-motile, filamentous branches; other properties include being catalase-positive and methenamine silver-positive.

In the last 30 years, gram-positive bacteria have been the most frequent pathogens in bloodstream infections in cancer patients. However, more recently, an increase in the frequency of bacteremias caused by gram-negative rods has been reported in many centers worldwide, with gram-negative pathoge...

are small Gram-negative cocco-bacilli, which are nonmotile, noncapsulate, and nonspore-forming. They are catalase positive and mainly oxidase positive. Francisella tularensis is a small, nonmotile, bipolar staining Gram-negative coccobacillus. It is an obligate aerobe and grows poorly on ordinary...
