What else can I help you with?
Does bacilus subtilis test negative for coagulase test?
Yes, Bacillus subtilis is negative for the coagulase test. Coagulase is an enzyme produced by some bacteria (such as Staphylococcus aureus) that causes blood plasma to clot, resulting in a positive test. Bacillus subtilis does not produce coagulase, so it will not clot the plasma and will have a negative test result.
Can staphylococcus saprophyticus hydrolyse starch?
No, it is negative
Is staphylococcus epidermitis gram positive or negative?
Gram positive.
The effect of ampicillin chloramphenicol erythromycin methicillin penicillin streptomycin sulphafurazole tetracycline on staphylococcus albus pseudomonas fluorescents micrococcus luteus baci?
Ampicillin, erythromycin, penicillin, and methicillin are effective against Staphylococcus albus but not against Pseudomonas fluorescens. Chloramphenicol, erythromycin, and streptomycin are effective against Pseudomonas fluorescens. Chloramphenicol and erythromycin are effective against Micrococcus luteus. Tetracycline is effective against Bacillus sp., including Bacillus subtilis. Sulphafurazole is effective against many gram-negative bacteria, including Pseudomonas fluorescens.
Is staphylococcus arueus of upper resp gram positive or gram negative?
S. arureus is a gram posotive cocciScientific classificationDomain:BacteriaKingdom:EubacteriaPhylum:FirmicutesClass:BacilliOrder:BacillalesFamily:StaphylococcaceaeGenus:StaphylococcusSpecies:S. aureus
What does not belong with the others bacillus escerichia lactobacillus staphylococcus streptococcus?
Escherichia does not belong...bacteria of this Genus are Gram negative, the rest are Gram positive bacteria.
Does bacilus subtilis test negative for coagulase test?
Yes, Bacillus subtilis is negative for the coagulase test. Coagulase is an enzyme produced by some bacteria (such as Staphylococcus aureus) that causes blood plasma to clot, resulting in a positive test. Bacillus subtilis does not produce coagulase, so it will not clot the plasma and will have a negative test result.
Is staphylococcus a gram-negative or gram-positive bacterium?
Staphylococcus is a gram-positive bacterium.
Can staphylococcus saprophyticus hydrolyse starch?
No, it is negative
Is staphylococcus epidermitis gram positive or negative?
Gram positive.
Which bacilli are gram positive oxidase negative and catalase positive?
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.
What is Urease test results for bacillus cereus?
Bacillus cereus is positive for the urease test, meaning it can break down urea to produce ammonia and increase the pH of the media. This can be observed by a color change in the media from yellow to pink or magenta.
Is Escherichia coli gram negative or gram positive?
it is Bacillus with gram negative.
The effect of ampicillin chloramphenicol erythromycin methicillin penicillin streptomycin sulphafurazole tetracycline on staphylococcus albus pseudomonas fluorescents micrococcus luteus baci?
Ampicillin, erythromycin, penicillin, and methicillin are effective against Staphylococcus albus but not against Pseudomonas fluorescens.

Tetracycline is effective against Bacillus sp., including Bacillus subtilis. Sulphafurazole is effective against many gram-negative bacteria, including Pseudomonas fluorescens.
Is bacillus subtilis positive or negative for starch hydrolysis?
it is positive for starch hydrolysis
What are some examples of gram positive bacteria in microbiology?
TEN EXAMPLES OF GRAM NEGATIVE BACTERIA ARE:1. Staphylococcus2. Streptococcus3. Enterococcus4. Bacillus5. Corynebacterium6. Nocardia7. Clostridium8. Actinobacteria9. Listeria10. Mycoplasma.
On the basis of gram reaction only can you distinguish between staphylococcus and streptococcus?
If the Gram stain is properly done, and based on color alone: - you CANNOT distinguish between Staphylococcus (positive/purple) and Streptococcus (positive/purple) - you CAN distinguish between Staphylococcus (positive/purple) and Neisseria (negative/red) - you CANNOT distinguish between Escherichia (negative/red) and Proteus (negative/red) - you CAN distinguish between Escherichia (negative/red) and Bacillus (positive/purple) Gram positives will stain purple because of the retention of the dye (crystal violet) in their thick peptidoglycan cell walls. On the other hand, Gram negatives have a thin cell wall and cannot retain the purple stain, so when they are counterstained, they will appear red
