Clinical manifestations are similar to those of GABHS pharyngitis, although about half of patients with A haemolyticum pharyngitis develop a rash, Arcanobacterium haemolyticum Infections.

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. 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.

One third of the patients had a history of recurrent tonsillitis. 2011-05-12 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. 2008-06-01 Abstract. 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. Abstract. 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.

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.

I t is associated primarily with human pharyngitis and mixed wound infections. Subperiosteal and peritonsillar abscess, osteomyelitis, endocarditis and septicaemia due to Arcanobacterium haemolyticum have been reported.

There are increasing reports of systemic infections caused by this organism. From India, we report the first case of Arcanobacterium haemolyticum causing pyothorax in an immunocompetent adolescent male patient.

In 1982 the previously named Corynebacterium haemolyticum was included in a new genus to reflect major differences in cell wall components and chemotaxonomic characters, the genus 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 (Arcanobacterium haemolyticum infections).

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%). In this age group, 2% of the throat cultures proved positive for A. haemolyticum. Arcanobacterium haemolyticum was found in 1.4% and beta-haemolytic streptococci in 23% of throat cultures from army conscripts with sore throat (n = 498).

PDF | Introduction Arcanobacterium haemolyticum (formerly known as Corynebacterium haemolyticum) is the causative agent of sore throat and also causes.

Arcanobacterium haemolyticum, formerly known as Corynebacerium haemolyticum, is a gram-positive bacillus. While A. haemolyticum is part of the normal flora of the pharynx, it can sometimes be a causative agent of pharyngitis. 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.

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.
