Arcanobacterium Haemolyticum (A. 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. It has been known to cause head and neck infections, pharyngitis, and sinusitis (Arcanobacte Arcanobacterium haemolyticum: clinical significance, diagnosis, and antimicrobial therapy. Arcanobacterium haemolyticum is a causative agent of pharyngitis, skin and soft tissues infections, and can cause severe infections in patients with pneumonia, osteomyelitis, septicemia, and pneumothorax.

The difficulties still encountered in the clinical diagnosis are underlined, since this organism could easily pass unrecognized in bacteriological cultures. 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 (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 …. Arcanobacterium haemolyticum (A.h.) was Pharyngitis and exanthema caused by Arcanobacterium haemolyticum.

In an 18-month period all throat cultures in our laboratory were examined for Arcanobacterium haemolyticum and clinical information was obtained. The great majority of the patients suffered from pharyngitis or tonsillitis, accompanied by a rash in 46% of cases. One third of the patients had a history of recurrent tonsillitis.

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%).

A haemolyticum exhibits variable susceptibility to penicillin and is identified more easily on human or rabbit blood agar than on sheep agar, the media traditionally used to identify GABHS. It is Request PDF | On Jun 1, 2001, P Carlson and others published Pharyngitis and exanthema caused by Arcanobacterium haemolyticum [5] | Find, read and cite all the research you need on ResearchGate 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%). Arcanobacterium haemolyticum is a gram-positive rod that has been reported to cause acute pharyngitis and scarlet fever-like rash, particularly in teenagers and young adults.

Throat culture is the gold standard for diagnosing streptococcus pharyngitis. G streptococci, Fusobacterium necrophorum, Arcanobacterium haemolyticum, Arcanobacterium haemolyticum has been implicated mainly in non-streptococcal pharyngitis and wound infections.

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. 2017-04-24 2017-04-24 Infection with Arcanobacterium haemolyticum, a gram-positive rod, causes pharyngitis, typically in adolescents and young adults. One report that analyzed 3992 throat cultures for A. haemolyticum and beta-hemolytic streptococci found that 0.5% of throat cultures were positive for A. haemolyticum , and most patients with positive cultures with this organism were between 15 and 25 years old. In an 18-month period all throat cultures in our laboratory were examined for Arcanobacterium haemolyticum and clinical information was obtained. The great majority of the patients suffered from pharyngitis or tonsillitis, accompanied by a rash in 46% of cases.
