Yes, there are gram-positive spiral bacteria, known as spirochetes. One example is the bacteria Treponema pallidum, which causes syphilis. Spirochetes are characterized by their helical shape and flagella that run along the length of their cell body, allowing them to move in a corkscrew-like motion.

Which type of bacteria are present in curd either gram plus ve or gram -ve bacteria?
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.
Candida albicans gram positive or gram negative?
Candida albicans is a yeast and belongs to the fungal kingdom, so it does not have a gram classification like bacteria. Gram staining is a technique used to differentiate between gram-positive and gram-negative bacteria based on the composition of their cell walls.
Are archaebacteria gram positive or gram negative?
Archaebacteria are neither gram positive nor gram negative because they do not have peptidoglycan in their cell walls like bacteria. Instead, they have unique cell wall structures that make them distinct from both gram positive and gram negative bacteria.
What type of gram is H1N1 bacteria gram-positive or gram-negative?
H1N1 is a virus, not a bacteria. Viruses do not have cell walls like bacteria, so they are not classified as gram-positive or gram-negative.
Is hepatitis B gram negative or gram positive?
Hepatitis B virus is not a gram-negative or gram-positive bacterium because it is a virus, not a bacteria. Viruses do not have cell walls like bacteria, so they are not classified as gram-negative or gram-positive.
What shape are the gram positive bacteria?
The shape is not specific it could be coccus(spiral), spirila, or bacillus(rod), depends on the bacteria. Gram positives are more complex and need different antibiotics to get rid of them, like tetracycline
How do gram positive bacteria protect themselves?
Gram positive bacteria protect themselves using antibiotic resistance and their flagella to move. They do not have a membrane like the gram negative bacteria.
Which type of bacteria are present in curd either gram plus ve or gram -ve bacteria?

H1N1 is a virus, not a bacteria. Viruses do not have cell walls like bacteria, so they are not classified as gram-positive or gram-negative.
Is hepatitis B gram negative or gram positive?
Hepatitis B virus is not a gram-negative or gram-positive bacterium because it is a virus, not a bacteria. Viruses do not have cell walls like bacteria, so they are not classified as gram-negative or gram-positive.
Is HIV gram positive or gram negative?
HIV is a retrovirus that is not classified as either gram positive or gram negative. Gram staining is a test used to classify bacteria based on the structure of their cell walls, and it is not applicable to viruses like HIV.
Is herpes simplex gram positive or gram negative?
Herpes simplex virus is neither gram positive nor gram negative, as it is a virus and doesn't have a cell wall like bacteria do.
Can you elimintate gram positive bacteria from a gram positive gram negative mixture with mild detergent treatment?
No, mild detergent treatment would likely not effectively eliminate gram positive bacteria from a gram positive and gram negative bacterial mixture. Gram positive bacteria have thick peptidoglycan layers that make them more resistant to detergent treatment compared to gram negative bacteria. To selectively eliminate gram positive bacteria, other treatments such as antibiotics or disinfectants targeting gram positive bacteria specifically would be more effective.
What is the advantage of the gram stain over the simple stain?
gram staining differentiates between gram negative and gram positive bacteria by showing different colors. it shows blue or purple like color for gram positive bacteria and red color for gram negative bacteria. where as simple stain gives the same color to all the types of bacteria. hence it is difficult to differentiate between them.
Will staph grow on EMB agar?
Staphylococcus bacteria typically do not grow well on Eosin Methylene Blue (EMB) agar. EMB agar is selective for gram-negative bacteria, particularly Enterobacteriaceae, and contains dyes that inhibit the growth of gram-positive bacteria like Staphylococcus.
