Which bacteria are gram-positive bacilli?
Which bacteria are gram-positive bacilli?

- Anthrax.
- Diphtheria.
- Enterococcal infections.
- Erysipelothricosis.
- Listeriosis.
What types of bacteria are catalase positive?
Staphylococci and Micrococci are catalase-positive. Other catalase-positive organisms include Listeria, Corynebacterium diphtheriae, Burkholderia cepacia, Nocardia, the family Enterobacteriaceae (Citrobacter, E.
Are all Gram-positive bacteria catalase positive?
Staphylococcus and Micrococcus spp. are catalase positive, whereas Streptococcus and Enterococcus spp. are catalase negative. If a Gram-positive cocci is catalase positive and presumed to be a staphylococci, the coagulase test is often performed.
Is gram positive bacilli serious?
Though gram-negative bacteria are harder to destroy, gram-positive bacteria can still cause problems. Many species result in disease and require specific antibiotics.
What is Gram positive cocci meningitis?
Gram positive cocci bacteria include Staphylococcus aureus, Streptococcus pyogenes and Streptococcus pneumoniae. While Gram-negative cocci bacteria include Neisseria gonorrhoeae and N. meningitidis. Gram positive cocci bacteria are responsible for one-third of all bacterial infections in humans.
Is Gram positive diplococci?

Examples of gram-negative diplococci are Neisseria spp., Moraxella catarrhalis, and Acinetobacter spp. Examples of gram-positive diplococci are Streptococcus pneumoniae and Enterococcus spp. Oct 1 2019
What antibiotic is used for Gram positive cocci?
Penicillin G is most effective for treating anaerobic gram-positive cocci and microaerophilic streptococci. Other effective agents include other penicillins , cephalosporins, chloramphenicol , clindamycin, vancomycin , telithromycin, linezolid , quinupristin/dalfopristin, and carbapenems.
What makes a Gram positive organism Gram positive?
Gram-positive bacteria are bacteria with thick cell walls. In a Gram stain test, these organisms yield a positive result. The test, which involves a chemical dye, stains the bacterium’s cell wall purple. Gram-negative bacteria, on the other hand, don’t hold the dye.
