Are gram-positive cocci aerobic or anaerobic?

Anaerobic gram-positive cocci of clinical significance are found in three gram-positive genera (Peptostreptococcus, Gemella, and Streptococcus) and one gram-negative genus (Veillonella). There are other genera of anaerobic cocci, but they are rarely isolated from clinical specimens.

Which type of cocci are gram-positive obligate anaerobes?

Gram-positive anaerobic cocci (GPAC) are better known to most bacteriologists as peptococci or peptostreptococci; most clinical isolates are identified to species in the genus Peptostreptococcus.

What causes gram-positive cocci in chains?

Staphylococcus aureus aureus is the most common cause of AHO and septic arthritis. It appears on Gram stain as Gram-positive cocci in clusters. S. aureus usually can be treated successfully with semisynthetic penicillins (e.g., oxacillin, nafcillin) or first generation cephalosporins (e.g., cefazolin).

Are gram-positive bacteria anaerobes?

Abstract. Among the Gram-positive anaerobic bacteria associated with clinical infections, the Gram-positive anaerobic cocci (GPAC) are the most prominent and account for approximately 25–30% of all isolated anaerobic bacteria from clinical specimens.

What does gram positive cocci mean?

noun, singular: gram-positive coccus. A group of spherical bacteria that retains the violet stain following gram staining. Supplement. Gram staining is a useful method for the rapid identification of bacterial species, especially those that are causing disease.

Is gram-positive cocci serious?

Gram-positive cocci: Staphylococcus aureus is a gram-positive, catalase-positive, coagulase-positive cocci in clusters. S. aureus can cause inflammatory diseases, including skin infections, pneumonia, endocarditis, septic arthritis, osteomyelitis, and abscesses.

What are Gram positive rods?

Description of Gram-positive rods. Gram-positive rods: A large group of rod-shaped bacteria that retains the crystal violet stain when treated by Gram’s method. Source: Diseases Database.

What is Gram positive in clusters?

Gram positive cocci in clusters is usually an indication that you have staphylococcus in the culture. This is an organism which can cause a number of infections ranging from skin infections to pneumonia to bloodstream infections.

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.
