The bacterium now named Arcanobacterium haemolyticum was first described in 1946 as the pathogenic agent causing pharyngitis and cutaneous infections among US service members and indigenous peoples of the South Pacific. [1, 2] As a result of its close resemblance to Corynebacterium pyogenes, some investigators believed the bacterium to be a mutant of this species and appended a …
Arcanobacterium haemolyticum was found in 1.4% and beta-haemolytic streptococci in 23% of throat cultures from army conscripts with sore throat (n = 498). 38% of the beta-haemolytic streptococci were of group A. Patients culture-positive for A. haemolyticum or beta-haemolytic streptococci had pharyngeal exudate, cervical lymphadenopathy and ear ache significantly more often--but cough less often--than …
Despite its prevalence, many emergency and primary care physicians may not be A. haemolyticum is reported as an in- frequent cause of peiitonsiDar abscess, pharyngitis, and tonsiDitis in children and young adults (>4). It was cultured from 12 of 129 children with pharyngotonsilli tis or scarlet fever, some of whom had a scarletiniforrn rash (5). Conclusions: Arcanobacterium haemolyticum infection should be considered in the differential diagnosis when evaluating a young adult with an exanthem. Antibiotic treatment is reliably efficacious, but the throat swab must be specifically cultured on 5% human blood agar in order to make the diagnosis. Arcanobacterium haemolyticum C. haemolyticum was first described and named by MacClean et al.
Conclusions: Arcanobacterium haemolyticum infection should be considered in the differential diagnosis when evaluating a young adult with an exanthem. Antibiotic treatment is reliably efficacious, but the throat swab must be specifically cultured on 5% human blood agar in order to make the diagnosis. Arcanobacterium haemolyticum C. haemolyticum was first described and named by MacClean et al. (14), who isolated it from pharyngeal infections in U.S. soldiers and natives in the South Pacific. Arcanobacterium haemolyticum was recovered from 0.5% of throat cultures of 3,922 patients seeking medical attention because of sore throat. Most of the patients positive for A. haemolyticum were 15–25 years old, and had fever (80%), lymphadenopathy (67%), pharyngeal exudate (69%) or skin rash (23%).

Haemolyticum), a coryneform Gram-positive bacillus, is a rare cause of head and neck infections, pharyngitis and sinusitis in teenagers and young adults 1 2. It is rarely isolated in most clinical laboratories, due to many difficulties in its recognition. Arcanobacterium haemolyticum, formerly known as Corynebacterium hæmolyticum, is a species of bacteria classified as a gram-positive bacillus. It is catalase-negative, aerobic, beta-hemolytic, and not motile.
No controlled trials of antimicrobial therapy have been conducted for pharyngitis caused by A haemolyticum. Many patients with pharyngitis have been treated with 1 dose of intramuscular penicillin

Detecting this agent requires special methods for culture, and it has not routinely been … 1. Acta Derm Venereol.

Pharyngitis Jump to Therapy Menu Etiology - Majority of cases (> 70%) of pharyngitis are of viral etiology and do not require antimicrobial therapy. - Group A Streptococcus (GAS) is most common bacterial cause of pharyngitis. - Occasionally pharyngitis is caused by Group C or G Streptococci, or Arcanobacterium haemolyticum.
G streptococci, Fusobacterium necrophorum, Arcanobacterium haemolyticum, Arcanobacterium haemolyticum has been implicated mainly in non-streptococcal pharyngitis and wound infections.
Infection with Arcanobacterium haemolyticum, a gram-positive rod, causes pharyngitis, typically in adolescents and young adults.
Antibiotic treatment is reliably efficacious, but the throat swab must be specifically cultured on 5% human blood agar in order to make the diagnosis. Arcanobacterium haemolyticum (A.h.) was recovered from 0.43% of throat cultures of 3715 patients with sore throat, scarlatina and various skin rash.
