Arcanobacterium haemolyticum is an organism that commonly causes pharyngitis and wound infections. It does not usually cause systemic invasive disease. The organism presents a difficult diagnostic problem because the Clinical Microbiology laboratory has a propensity to view them as diphtheroid organisms of the Corynebacterium species, thus contaminants or normal flora.

Blood cultures were drawn Arcanobacterium on the basis of genetic analysis in. 1982, and has been associated with pharyngitis, recurrent throat infections, wound infections, septicaemia Introduction. Arcanobacterium Haemolyticum (A. Haemolyticum), a coryneform Gram-positive bacillus, is a rare cause of head and neck infections, pharyngitis and Corynebacterium diphtheria, C. ulcerans — cause diphtheria. Arcanobacterium haemolyticum — causes arcanobacterial pharyngitis. Yersinia enterocolitica — Arcanobacterium haemolyticum has been associated with tonsillitis, pharyngitis and may cause a rash in young adults and occasionally in children.

abstract = "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. Trueperella pyogenes (Arcanobacterium) looks the same like A. haemolyticum in Gram stain and colony morphology, but T pyogenes is slightly larger and with increased hemolysis McConkey no growth BBAØ growth Characteristics. Gram-positive bacilli difteroid growth both-aerobic-and-anaerobic haemolyticum, a beta-hemolytic organism that can cause pharyngitis and wound infections.

of the human pathogen Arcanobacterium haemolyticum B Helen Jost1, Erynn A Lucas1, Stephen J Billington2, Adam J Ratner3* and David J McGee4* Abstract Background: Arcanobacterium haemolyticum is an emerging human pathogen that causes pharyngitis, wound infections, and a variety of occasional invasive diseases.

Arcanobacterium haemolyticum pharyngitis

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.

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. 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%).

Detecting this agent requires special methods for culture, and it has not routinely been sought in patients with scarlet fever or pharyngitis. MICROBIOLOGY Arcanobacterium haemolyticum was first described by MacLean et al. in 1946 (26) as a pathogen in cases of exudative pharyngitis and soft-tissue 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. The role of A. hemolyticum as an animal Rhodococcus equi and Arcanobacterium haemolyticum, formerly classified in the genus Corynebacterium, are members of the loosely defined taxon "coryneform" bacteria. Although they are the etiologic agents of distinct human infections, both organisms are frequently overlooked, which results in missed or delayed diagnoses.

Tonsillitis and rash associated with Corynebacterium haemolyticum. J Infect DiS 1986;154:1937-l940. 2. Karpathios T et al. Arcanobacterium haemolyticum in

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.
