Does Chryseobacterium grow on MacConkey?
Most strains of C. indologenes do not grow on MacConkey agar, but grow well on blood agar after 24 h incubation at 37°C [3-4]. This bacteria produces a biofilm on foreign materials (i.e., indwelling devices) and protease activity that may play an important role in the virulence of invasive infections [4, 9]. C.
Is sphingomonas oxidase positive?
Sphingomonas paucimobilis (S. paucimobilis), is a gram-negative, aerobic, non-fermentative, oxidase (+) and catalase (+) bacterium.
Is Chryseobacterium Gram-negative?
Chryseobacterium species are Gram negative, aerobic, nonfermentative, oxidase-positive, catalase-positive, and non-motile bacilli [1-2]. They produce a distinctive yellow to orange pigment on blood agar [3-4]. The most frequent isolates of Chryseobacterium species include Chryseobacterium indologenes, C.
Is Chryseobacterium gram negative?
Is sphingomonas gram positive?
Sphingomonas paucimobilis (S. paucimobilis) is a gram negative bacillus. It has existed in soil, drinking water and plants. It has been isolated from distilled water tanks, respirators, and hemodialysis devices at the hospital setting.
Does sphingomonas grow on MacConkey?
Sphingomonas spp., Sphingobacterium spp., Acidovorax facilis, and all CDC groups considered in this chapter grow well on routine laboratory media, such as 5% sheep blood and chocolate agars; however, most fail to grow on MacConkey agar.
What is the shape of C Indologenes?
C. indologenes is a yellow-pigmented, non-motile, oxidase positive, glucose non-fermentative, Gram-negative rod-shaped bacterium widely distributed in nature.
Is Stenotrophomonas gram-negative or positive?
gram-negative
Stenotrophomonas (Xanthomonas) maltophilia is a multidrug-resistant gram-negative bacillus that is an opportunistic pathogen [1-4], particularly among hospitalized patients.
