Arcanobacterium haemolyticum osteomyelitis and sepsis: a diagnostic conundrum. Surg Infect (Larchmt) 2013; 14:322. Miyamoto H, Suzuki T, Murakami S, et al. Bacteriological characteristics of Arcanobacterium haemolyticum isolated from seven patients with skin and soft-tissue infections.
Arcanobacterium haemolyticum (A.h.) was recovered from 0.43% of throat cultures of 3715 patients with sore throat, scarlatina and various skin rash. In a 57.90% patients A.h. was the only bacterial pathogen isolated, while in the remainder beta-haemolytic streptococci, Haemophilus and S. aureus were also detected. beta-haemolytic streptococci were much more frequent than A.h. in the throat cultures (26.83%).
In two patients, one with cellulitis and the other with postoperative wound infection following amputation of the limb, Arcanobacterium haemolyticum was isolated repeatedly along with beta haemolytic streptococci (BHS). Arcanobacterium hemolyticum is a β‐hemolytic Gram‐positive, pleomorphic, facultative anaerobic, non‐acid‐fast rod that has been implicated as an etiologic agent of non‐streptococcal pharyngitis, especially in adolescents and young adults, as well as a cause of skin and wound infections, osteomyelitis, sepsis, and central nervous system infections. Performing the optochin test. 1) Using a inoculation loop, steak two or three suspect colonies of a pure culture to be tested on 5% sheep blood agar plate. 2) Place an optochin disc (6mm, 5 µg) within the streked area of the plate.

Show abstract. Infections of the pharynx. Arcanobacterium haemolyticum, tidigare Corynebacterium haemolyticum, har beskrivits som orsak till svalginfektioner hos ungdom mellan 10 och 30 år, icke så sällan tillsammans med skarlatineformt utslag. Prevalensen hos svalginfekterade har angivits till 2 % och hos friska i samma ålder till 0,2-0,5 % (1-3).

2014年1月20日 Arcanobacterium haemolyticum の細菌学的検討. 愛媛大学 Table 3 Antimicrobial susceptibility of Arcanobacterium haemolyticum strains.
A. haemolyticum was resistant to cotrimoxazole and GGS was resistant to tetracycline. The susceptibilities of 138 clinical isolates of Arcanobacterium haemolyticum to 11 antimicrobial agents were tested. All strains were susceptible to phenoxymethylpenicillin, cephalosporins, erythromycin, azithromycin, clindamycin, vancomycin, doxycycline, and ciprofloxacin but were resistant to trimethoprim-sulfamethoxazole. In vitro testing of A. haemolyticum isolated from human infections shows susceptibility to erythromycin, gentamicin, clindamycin, and cephalosporins (42).

From India, we report the first case of Arcanobacterium haemolyticum causing pyothorax in an immunocompetent adolescent male patient. The probable mode of infection is also discussed. Arcanobacterium (/ ɑːr ˈ k eɪ n oʊ b æ k ˌ t ɪər i ə m /) is a genus of bacteria.They are gram-positive, non–acid fast, nonmotile, facultatively anaerobic, and non–endospore forming. They are widely distributed in nature in the microbiota of animals (including the human microbiota) and are mostly innocuous.Some can cause disease in humans and other animals (for example Arcanobacterium haemolyticum, formerly known as Corynebacterium haemolyticum, is a bacterium classified as a Gram-positive bacillus and is catalase-negative, aerobic, beta-haemolytic, nonmotile. It is part of the normal flora of the pharynx, but may cause head and neck infections, pharyngitis and sinusitis. In an 18-month period all throat cultures in our laboratory were examined for Arcanobacterium haemolyticum and clinical information was obtained.
