It is because pseudomonas poses outer membrane. That is why it doesnot a gram positive bacteria.

Is mycobacteria a gram positive?

Neky said: (May 19, 2015)  
That is the problem now, because mycobacteria does not undergo gram staining but acid fast stain.

Pseudomonas is gram negative.

How I conclude because both mycobacteria and pseudomonas are not gram positive?

Kedir Seid said: (Jun 17, 2016)  
Both psudomonas and mycobacteria are gram negative.

Admatha Chimwasu said: (Aug 30, 2016)  
Pseudomonas is gram negative.

Pseudomonas is gram negative bc outer available.

So I think pseudomonas and mycobacteria both are right options.

I agree the answer is pseudomonas, because mycobacteria is neither gram-positive nor gram-negative of course it seems like gram positive and the other g positive.

Yeah, mycobacteria is acid fast.

Pseudomonas are Gram negative bacteria. Because it's outer layer thin and phosphoglycan are absent.

Dominique said: (Oct 5, 2017)  
I agree that the answer is pseudomonas, because it is a gram negative.

Aishat said: (May 1, 2018)  
Streptococci are also gram negative bacteria while staphylococcus is gram positive.

Dwamena Patience said: (Oct 15, 2018)  
Pseudomonas is the answer because it posses the characteristics of gram negative.
