evaluation of the rapid cb plus system for identification of corynebacterium species and other gram-positive rods.due to the difficulty of identifying corynebacterium spp. with standard methods, we compared them with the rapid cb plus system (remel, lenexa, kans. [formerly innovative diagnostic systems, norcross, ga.]), which consists of 4 carbohydrate and 14 preformed enzyme tests, for the identification of 98 clinical isolates of corynebacterium sp., other coryneforms, listeria monocytogenes, and 17 atcc strains. forty (95%) of 42 strains of corynebacterium spp. were accurately identified to the species l ...19989466773
actinomyces pyogenes septic arthritis in a diabetic farmer.we report a case of septic arthritis and osteomyelitis of the left ankle due to actinomyces pyogenes in a diabetic farmer. few confirmed human cases of a. pyogenes infection have been reported, partly because of inadequate identification of this bacterium. bacteriological characteristics of the organism, which resembles arcanobacterium haemolyticum, are described with a review of previous case reports.19989733386
phospholipase d-neutralization in serodiagnosis of arcanobacterium haemolyticum and corynebacterium pseudotuberculosis infections.phospholipase d (pld) neutralization was used to examine sera of humans (n = 40) with a spontaneous infection by arcanobacterium haemolyticum, sheep and goats (n = 76 and 79 respectively) with a spontaneous infection by corynebacterium pseudotuberculosis, mice (n = 26) experimentally immunized with pld from a. haemolyticum (pld-a) and mice (n = 28) experimentally immunized with pld from c. pseudotuberculosis (pld-c). pld-a and pld-c were also used as neutralizing antigens. a positive result of n ...19989987184
systemic and deep-seated infections caused by arcanobacterium haemolyticum.arcanobacterium haemolyticum has been implicated mainly in non-streptococcal pharyngitis and wound infections. rarely, it has been reported to cause systemic infection, often in combination with other pathogens. two cases of systemic and deep-seated infections caused by arcanobacterium haemolyticum are reported, and the literature is reviewed. sixteen cases of bacteremia and seven cases of non-bacteremic deep-seated have been published previously. eight of the bacteremic and two of the non-bacte ...19989796659
[bacteriological and clinical aspects of corynebacterium].the microbiologists use the term corynebacteria to describe aerobically growing, asporogenous, irregularly sharped gram-positive rods. they comprise strictly aerobic bacteria isolated from environment as well as preferentially anaerobic bacteria found in clinical specimens. a large part of these bacteria is considered as commensal of skin and mucous membranes. this group of organisms has recently been subjected to considerable taxonomic revisions, which have resulted in the proposal of several n ...19989754261
antimicrobial susceptibilities and biotypes of arcanobacterium haemolyticum blood isolates.isolates obtained from the blood of ten patients with arcanobacterium haemolyticum septicaemia were biotyped as smooth or rough using morphological and biochemical criteria, and their susceptibilities to 18 antibacterial agents were determined. nine of the clinical cases included here have not been reported previously and are discussed in brief. one of the strains was highly resistant to macrolides and clindamycin. with one exception, the strains belonged to the smooth biotype. the data presente ...199910691208
arcanobacterium haemolyticum and mycoplasma pneumoniae co-infection.systemic infection caused by arcanobacterium haemolyticum is uncommon. we report a case of empyema and bacteraemia caused by this organism concomitant with mycoplasma pneumoniae infection.199910090506
[a diagnostic medium for arcanobacterium haemolyticum and other bacterial species reacting with hemolytic synergism to the equi-factor of rhodococcus equi].colonies of arcanobacterium haemolyticum on common blood agar can be easily overlooked. therefore a diagnostic medium was developed, on which a. haemolyticum colonies produce a conspicuous zone of complete hemolysis. the medium under question is blood agar prepared from the columbia blood agar base and 5% washed sheep erythrocytes sensitised with equi factor (ef) of rhodococcus equi. optimally, 10 activity units (au) of ef per 1 ml were used. ef was titrated on a non-nutrient medium consisting o ...200011040494

three cases of arcanobacterium haemolyticum associated with abscess formation and cellulitis.arcanobacterium haemolyticum has been described as an unusual pathogen causing pharyngotonsillitis and systemic disease in patients with predisposing conditions. a case of soft tissue abscess with no apparent portal of entry is reported in a healthy 31-year-old man who presented with a breast tumor. a second case of abscess formation in a 50-year-old patient with complicated wound healing is presented. in addition, a case of arcanobacterium haemolyticum cellulitis in a 25-year-old female is repo ...199910614955
upper respiratory tract infections in adolescents.while upper respiratory tract infections (urtis) cause much infectious morbidity in infants and young children, adolescents are not immune to infections. adolescents experience two to four episodes of viral nasopharyngitis annually. in addition to group a streptococcus (gas), pharyngitis may occur with other streptococci, arcanobacterium haemolyticum, epstein-barr virus, neisseria gonorrhoeae, and other pathogens. uvulits, typically in association with gas, occurs occasionally. peritonsillar abs ...200010916122

periodontal bacteria in rabbit mandibular and maxillary abscesses.despite the high incidence of odontogenic abscesses in pet rabbits, published data on the bacteriology of these infections are lacking, and clinical cultures are often ambiguous, making antibiotic choices difficult. in order to define the bacteriology of these infections, 12 rabbit mandibular and maxillary abscesses were cultured aerobically and anaerobically. all specimens yielded pathogenic bacteria, including fusobacterium nucleatum, prevotella heparinolytica, prevotella spp., peptostreptococ ...200211880435
arcanobacterium hippocoleae sp. nov., from the vagina of a horse.a polyphasic taxonomic study was performed on a previously unidentified gram-positive, facultatively anaerobic, diphtheroid-shaped organism isolated from a vaginal discharge of a horse. comparative 16s rrna gene sequencing demonstrated that the strain was a member of the genus arcanobacterium, but sequence divergence values of >4% with described species of this genus (viz: arcanobacterium haemolyticum, arcanobacterium bernardiae, arcanobacterium phocae, arcanobacterium pluranimalium and arcanoba ...200211931175
[detection of arcanobacterium haemolyticum in primoculture using the reverse camp test].arcanobacterium haemolyticum was isolated from 8,641 throat swabs in 49 cases (0.56%), from patients aged 16 to 24 years only, twice more often from men than from women. the isolation was achieved on sheep blood agar supplemented with streak with staphylococcus aureus strain producing beta-lysine. in all cases the presence of a. haemolyticum colonies was disclosed by the irregular periphery of haemolysis around the staphylococcal streak after the 48-hour incubation. the technique described shoul ...200111329730
lemierre's disease caused by co-infection of arcanobacterium haemolyticum and fusobacterium necrophorum: a case report.we report the first case of lemierre's disease caused by a co-infection with a. haemolyticum and f. necrophorum. a characteristic skin rash and predominant growth on multiple blood cultures suggests a causative role for arcanobacterium. failures of penicillin therapy in a. haemolyticum infections should be considered when the initial antibiotic regimen is chosen.200212217717
[infections by arcanobacterium haemolyticum: an emerging pathogen].arcanobacterium haemolyticum is a grampositive rod wich belonged, until a short time ago, to corynebacterium genus, and recently classified in a new genus, with only one specie. human is the main reservoir. it has been isolated from the skin and pharinx of healthy individuals, but also it is cause of infection, specially pharingitis, in children, and chronic cutaneous ulcus, in diabetic patients. less frequently, it is cause of osteomyelitis, meningitis, pneumonia, abscess, endocarditis and seps ...200212420635
