gram negative
No, Staphylococcus Aureus is a gram positive facultative anaerobe. It has a cell wall surrounding a peptidoglycan layer, however does not produce an endospore like many other gram positive bacteria. Staphylococcus Aureus is a cocci shaped bacteria with pyogenic properties.
A negative result for a spore stain indicates that the organism does not form endospores. Endospore formation is a survival mechanism for some bacteria to withstand harsh environments, so a negative result suggests that the organism may be more susceptible to environmental stressors.
Pseudomonas aeruginosa does not form endospores. In Gram staining, it typically stains gram-negative due to its thin peptidoglycan layer and outer lipid membrane.
Streptobacillus is a gram negative, oxidase negative, catalase negative, non motile organism, and 0.3-0.7 µm by 1-5 µm in lengthEscherichia coliMost of the Enterobacteriaceae are Catalase Positive. E. coli is Catalase Positive and Oxidase Negative. Do not report the previous as an answer. For gram negative, catalase negative and oxidase negative rods, it is likely that you have bacteria of the Bacteroides genus.
Gram-positive bacteria and Gram-negative bacteria are different in their colouration when dyed and viewed with a light microscope. Gram-positive appear violet, and Gram-negative appear red. Gram-positive and Gram-negative classification, however, has nothing to do with size.

no. in general, only gram-positive bacteria such as Bacillus and Clostridium produce endospores.
Bacillus and Clostridium are the two main groups of gram-positive bacteria that are capable of forming endospores. Endospores are dormant, resistant structures that allow these bacteria to survive in harsh environments.

gram positive
No, Haemophilus influenzae is a gram-negative bacterium that does not produce endospores. Endospores are a unique survival structure produced by some species of bacteria, such as Bacillus and Clostridium.

Gram-positive cells are purple and the Gram-negative cells are red.
