gram-positive bacteria but can become gram negative if the smear is left to culture for a long period of time.
Two genera of bacteria that are gram variable are Mycobacterium and Corynebacterium. Gram variable bacteria may appear to be both gram-positive and gram-negative due to differences in their cell walls.
Coxiella species exhibit variable Gram stain results due to their unique cell wall structure, which contains features of both Gram-positive and Gram-negative bacteria. They possess a thick peptidoglycan layer typical of Gram-positive bacteria, but also have an outer membrane similar to that of Gram-negative bacteria. This dual characteristic can lead to inconsistent staining, depending on the specific conditions and techniques used during the Gram staining process. Additionally, their intracellular lifestyle and atypical growth patterns further contribute to the variability in staining results.
Kingdom Gram-Positive Bacteria is a kingdom within the domain Bacteria.
Gram positive
The bacteria present in curd are primarily Gram-positive bacteria. These include species like Lactobacillus acidophilus and Streptococcus thermophilus. Gram-negative bacteria are not typically found in curd as the fermentation process favors the growth of Gram-positive bacteria.
Two genera of bacteria that are gram variable are Mycobacterium and Corynebacterium. Gram variable bacteria may appear to be both gram-positive and gram-negative due to differences in their cell walls.
Gram-positive bacteria will appear purple or blue under a microscope due to retaining the crystal violet dye. Gram-negative bacteria will appear red or pink under a microscope due to losing the crystal violet dye and taking up the safranin counterstain. Gram-variable bacteria may show both purple and red/pink colors due to variations in their cell wall composition. Gram-indeterminate results may occur if the staining process is not carried out correctly or the bacteria are atypical in their cell wall structure.

Gram positive
i believe it is a gram bacteria which causes respiratory illness.
what are some of the reasons for a gram-variable reaction
Gram-negative bacteria have a thinner peptidoglycan layer in their cell walls compared to gram-positive bacteria. Additionally, gram-negative bacteria have an outer membrane that contains lipopolysaccharides, which is absent in gram-positive bacteria.

No, Gram-positive bacteria do not have lipopolysaccharides.
Typical gram-positive bacteria are staphylococci; typical gram-negative bacteria are bacilli.
Lactobacillus is gram positive bacteria
