How is Peptostreptococcus transmitted?
COMMUNICABILITY: Human-to-human transmission can occur through bite wounds(8). RESERVOIR: Humans and animals(1,7). ZOONOSIS: Transmission of the bacterium to humans via dog and cat bites has been reported(9).
What causes Peptostreptococcus?
Anaerobic infections in the skin and soft tissue can be caused by the cutaneous anaerobic flora, mainly Peptostreptococcus, but are most often caused by contamination with the flora from adjacent mucosal surfaces.
Is Peptostreptococcus contagious?
MODE OF TRANSMISSION: Infection is usually associated with trauma or disease( 1). INCUBATION PERIOD: Unknown. COMMUNICABILITY: Human-to-human transmission can occur through bite wounds( 8).
What is the function of Peptostreptococcus?
Peptostreptococcus can cause brain, liver, breast, and lung abscesses, as well as generalized necrotizing soft tissue infections. They participate in mixed anaerobic infections, a term which is used to describe infections that are caused by multiple bacteria that do not require or may even be harmed by oxygen.
Is Peptostreptococcus a type of streptococcus?
Anaerobic gram-positive cocci that produce large amounts of lactic acid during the process of carbohydrate fermentation were reclassified as Streptococcus parvulus and Streptococcus morbillorum from Peptococcus or Peptostreptococcus. Most of these organisms are anaerobic, but some are microaerophilic.
How is Peptostreptococcus treated?
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.
Is Peptostreptococcus harmful?
Peptostreptococci can cause fatal endocarditis, paravalvular abscess, and pericarditis. The most frequent source of bacteremia due to Peptostreptococcus are infections of the oropharynx, lower respiratory tract, female genital tract, abdomen, skin, and soft tissues.
Is Peptostreptococcus a type of Streptococcus?
Which antibiotic is ineffective against Peptostreptococcus?
Imidazoles are ineffective against some anaerobic gram-positive cocci and all aerotolerant strains. The newer quinolones are effective against more than 90% of anaerobic cocci; ciprofloxacin is less effective.
What is Fusobacterium?
Fusobacterium is a genus of anaerobic, Gram-negative, non-sporeforming bacteria, similar to Bacteroides. Individual cells are slender, rod-shaped bacilli with pointed ends. Strains of Fusobacterium cause several human diseases, including periodontal diseases, Lemierre’s syndrome, and topical skin ulcers.
