av H Hanberger · 2013 — tion of effective antimicrobial therapy is the critical determinant of survival in Arcanobacterium haemolyticum, Legionella pneumophila, Bordetella pertussis.

An Arcanobacterium haemolyticum infection is any of several types of infection with the gram-positive bacillus Arcanobacterium haemolyticum.It can cause an acute pharyngitis, and it may cause an exanthem characterized by an erythematous, morbilliform or scarlatiniform eruption involving the trunk and extremities.

Although serologic antibody tests for A. haemolyticum exist, none has been standardized or is commercially available. The organism is susceptible to penicillin, erythromycin, clindamycin, chloramphenicol, and tetracycline. All these agents appear appropriate for therapy. This article explores two pathogenic coryneform bacteria: Rhodococcus equi, a rare often fatal human pathogen, in which virtually all human infections occur among compromised hosts; and Arcanobacterium haemolyticum, which is responsible for many respiratory infections in healthy people. This article aims to bring about improved recognition of these two easily overlooked pathogens and considers mechanisms underlying the diseases, the immune response of the hosts, and treatment protocols.

Gram positive irregular bacilli (aerobic) Clinical Significance. This organism may be part of commensal flora of the respiratory and gastrointestinal tracts. Arcanobacterium bovis lesions can be prevented or minimized by feeds without coarse or sharp materials. Treatment. Penicillin or derivatives such as ampicillin or amoxicillin are treatments of choice.

Arcanobacterium haemolyticum is an infrequent agent of pharnygotonsillitis in children and young adults. Despite the fact that A. haemolyticum is fully sensitive to penicillin in vitro, penicillin treatment failures are frequent. The ability of A. haemolyticum to invade HEp-2 cells and survive intracellularly was investigated. All 12 strains tested, of which 10 were isolated from patients with

even a selective strep agar, is used to set up throat cultures, this overlooked and underreported cause of non-streptococcal pharyngitis is often missed. A. haemolyticum typically grows slowly and exhibits less well defined beta-hemolysis on sheep blood Arcanobacterium haemolyticum is an infrequent agent of pharnygotonsillitis in children and young adults. Despite the fact that A. haemolyticum is fully sensitive to penicillin in vitro, penicillin treatment failures are frequent.

One third of the patients had a history of recurrent tonsillitis. Three types of exanthema was described, scarlatiniform, urticarial 2015-11-21 Arcanobacterium haemolyticum is rarely isolated from clinical),material either in human or veterinary medicine. As for our country, there is only one official report with regard to the isolation Arcanobacterium Haemolyticum: two case reports Arcanobacterium Haemolyticum: due casi clinici M. Volante, l. Corina, a.M. ContuCCi, l. CalÒ, a. artuso institute of otolaryngology, Catholic university of sacred Heart, rome, italy Summary Two uncommon presentations of Arcanobacterium Haemolyticum infection (sinusitis and pharyngitis) are Arcanobacterium haemolyticum is an infrequent agent of pharyngotonsillitis in children and young adults.

in 1946 as a pathogen in cases of exudative pharyngitis and soft-tissue infections. In 1982 the previously named Corynebacterium haemolyticum was 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. Arcanobacterium haemolyticum has been implicated mainly in non-streptococcal pharyngitis and wound infections.

A. haemolyticum is commonly described in association with infective pharyngitis or soft tissue infections especially in the presence of underlying condition like diabetes. Less commonly reported infection includes osteomyelitis, brain abscess, and endocarditis.[ 5 ]

Macrolide antibiotics, such as erythromycin and clarithromycin, were also inhibitory to many strains. 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.

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. Detecting this agent requires special methods for culture, and it has not routinely been sought in patients with scarlet fever or pharyngitis.

Extended antibiotic therapy may be necessary. with Arcanobacterium haemolyticum in rural patients aged between 60-65 years. In two patients, one with cellulitis and the other with postoperative wound infection following amputation of the limb, Arcanobacterium haemolyticum was isolated repeatedly along with β haemolytic streptococci (BHS). The BHS belonged to Treatment.
