haemolyticum in South Korea. arms and legs. A. haemolyticum is a beta-hemolytic gram-positive, pleomorphic, facultative anaerobic rod that has been implicated as an etiologic agent of non-streptococcal pharyngitis, especially in adolescents and young adults. Corynebacterium haemolyticum, now named Arcanobacterium haemolyticum, was first

in 1946 (26) as a pathogen in cases of exudative pharyngitis and soft-tissue infections. 1. Acta Derm Venereol. 2001 May;81(2):143-4. Pharyngitis and exanthema caused by Arcanobacterium haemolyticum.

Acute pharyngitis attributable to Arcanobacterium haemolyticum often is indistinguishable from that caused by group A streptococci. Fever, pharyngeal exudate, lymphadenopathy, rash, and pruritus are common, but palatal petechiae and strawberry tongue are absent. This report describes a case of chorioamnionitis caused by Arcanobacterium haemolyticum, an unusual organism associated with this infection, described mostly in association with infective pharyngitis rarely with bacteremia and soft tissue infections. Arcanobacterium hemolyticum infections are a common cause of pharyngitis and rash in the 10- to 30-year-old age group.

Fever, headache, fatigue, and malaise are variably present. The specific microbiologic cause of pharyngitis can rarely be distinguished based on clinical features alone.

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 Two uncommon presentations of Arcanobacterium Haemolyticum infection (sinusitis and pharyngitis) are described, emphasizing the poor response to commonly used antibiotics and the possibility of serious local and systemic complications. 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.

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. One third of the patients had a history of recurrent tonsillitis. 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 2020-07-16 · Arcanobacterium haemolyticum is a rare infectious pathogen that principally causes pharyngitis in adolescents and soft-tissue infections in immunocompromised elderly patients. Its treatment consists of supportive care and antibiotics, resulting in a good prognosis without any long-term sequelae when recognized and treated promptly.
