first report of a parasitic copepod (pennella balaenopterae) infestation in a infestation by the parasitic copepod pennella balaenopterae was found in a stranded, 8-mo-old, female northern elephant seal (mirounga angustirostris). diagnosis was based on the finding of the cephalothoraxes of 14 adult female copepods from three subcutaneous sites. bacteria cultured from lesion exudate included arcanobacterium phocae, escherichia coli, edwardsiella tarda, an enterococcus sp., and proteus mirabilis. the lesions were drained and irrigated with chlorhexidine, and the seal was ...200212216795
synergistic and antagonistic hemolytic activities of bacteria of genus arcanobacterium and camp-like hemolysis of arcanobacterium phocae and arcanobacterium haemolyticum with psychrobacter phenylpyruvicus.a total of 57 bacteria representing eight species of genus arcanobacterium (a.) were investigated for hemolytic properties on blood agar containing sheep and rabbit blood and for camp-like reactions. an enhanced hemolysis on blood agar containing rabbit blood compared to sheep blood could be observed for a. haemolyticum, less pronounced for a. hippocoleae and a. pluranimalium. a synergistic hemolytic reaction with staphylococcal beta-hemolysin appeared to be constantly visible for a. hippocoleae ...200919249067
questionnaire survey of detrimental fur animal epidemic necrotic pyoderma in 2007, a previously unrecorded disease, fur animal epidemic necrotic pyoderma (fenp), was detected in farmed mink (neovision vision), foxes (vulpes lagopus) and finnraccoons (nyctereutes procyonoides) in finland. symptoms included severe pyoderma with increased mortality, causing both animal welfare problems and economic losses. in 2011, an epidemiologic questionnaire was mailed to all members of the finnish fur breeders' association to assess the occurrence of fenp from 2009 through the first ...201728774326
otariodibacter oris and bisgaardia genomospecies 1 isolated from infections in pinnipeds.we document the first associations of two recently described species of pasteurellaceae bacteria with lesions in wild pinnipeds in rehabilitation. samples were collected from nine lesions in four california sea lions (zalophus californianus) and two pacific harbor seals (phoca vitulina) during necropsy or admission examinations at a rehabilitation facility in northern california. seven pasteurellaceae isolates were identified using phenotypic tests and partial rpob gene sequencing. six strains o ...201323778617
characterization of a new epidemic necrotic pyoderma in fur animals and its association with arcanobacterium phocae infection.a new type of pyoderma was detected in finnish fur animals in 2007. the disease continues to spread within and between farms, with severe and potentially fatal symptoms. it compromises animal welfare and causes considerable economic losses to farmers. a case-control study was performed in 2010-2011 to describe the entity and to identify the causative agent. altogether 99 fur animals were necropsied followed by pathological and microbiological examination. the data indicated that the disease clin ...201425302603
staphylococcus spp., streptococcus canis, and arcanobacterium phocae of healthy canadian farmed mink and mink with pododermatitis.pododermatitis is a disease of concern for mink breeders in canada and worldwide, as it causes discomfort and lowers the breeding rates on farms affected by the disease. unfortunately, the etiology and pathogenesis of pododermatitis are still unknown. in this study, we compared staphylococcus spp. and streptococcus canis isolates from healthy mink with isolates from animals with pododermatitis on 2 farms in ontario. almost all hemolytic staphylococcus spp. isolated were shown to be staphylococcu ...201525852228
arcanobacterium pinnipediorum sp. nov., isolated from a harbour seal.a polyphasic taxonomic study was performed on an unidentified arcanobacterium-like, gram-stain-positive bacterium, strain 2710t, isolated from a harbour seal. comparative 16s rrna gene sequence analysis showed that this bacterial strain belonged to the genus arcanobacterium and was related most closely to the type strains of arcanobacterium phocae (98.4 % similarity) and arcanobacterium phocisimile (97.5 %). 16s rrna gene sequence similarities to the type strains of other arcanobacterium species ...201526373578
postvaccination wounds associated predominantly with arcanobacterium phocae in mink (neovison vison) at three mink farms.the emerging skin disease fur animal epidemic necrotic pyoderma (fenp) has been attributed to infection with arcanobacterium phocae (abp). the exact pathogenesis and risk factors of fenp have yet to be elucidated.201727917544
experimental infection of mink enforces the role of arcanobacterium phocae as causative agent of fur animal epidemic necrotic pyoderma (fenp).fur animal epidemic necrotic pyoderma (fenp) is a severe, often lethal infectious disease affecting all three fur animal species: mink (neovision vision), foxes (vulpes lagopus) and finnraccoons (nyctereutes procyonoides). previous studies showed an association between arcanobacterium phocae and fenp. an experimental infection was conducted to confirm the ability of a. phocae to infect mink either alone or concurrently with a novel streptococcus sp. found together with a. phocae in many cases of ...201627973532
arcanobacterium wilhelmae sp. nov., isolated from the genital tract of a rhinoceros (rhinoceros unicornis).abstracta polyphasic taxonomic study was performed on an unidentified arcanobacterium-like gram-stain-positive bacterium isolated from the genital tract of a rhinoceros. comparative 16s rrna gene sequencing showed that the bacterium belonged to the genus arcanobacterium and was most closely related to the type strains of arcanobacterium canis (98.8 %), arcanobacterium phocisimile (97.8 %), arcanobacterium phocae (97.7%), arcanobacterium haemolyticum (97.4 %), arcanobacterium hippocoleae (96.6 %) ...201728073403
Arcanobacterium canis sp. nov., isolated from an otitis externa of a dog and emended description of the genus Arcanobacterium Collins et al. 1982 emend. Yassin et al. 2011.A polyphasic taxonomic study was performed on previously unidentified Arcanobacterium-like Gram-positive bacteria isolated from otitis externa of a dog.Comparative 16S rRNA gene sequencing showed that the bacteria belonged to genus Arcanobacterium and were most closely related to Arcanobacterium haemolyticum (97.2%), Arcanobacterium hippocoleae (96.5%) and Arcanobacterium phocae (96.4%). The presence of the major menaquinone MK-9 H4 supported the affiliation of this strain to genus Arcanobacteri ...201122081713
characterization and clinical manifestations of arcanobacterium phocae infections in marine mammals stranded along the central california coast.between 1994 and 2000, 141 arcanobacterium phocae isolates were recovered from marine mammals that stranded along the central california coast (usa). arcanobacterium phocae was cultured from tissue sites with abnormal discharge or evidence of inflammation in 66 california sea lions (zalophus californianus), 50 pacific harbor seals (phoca vitulina richardii), 19 northern elephant seals (mirounga angustirostris), five southern sea otters (enhydra lutris nereis), and one common dolphin (delphinus d ...200312685077
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
phylogenetic analysis of the genus actinomyces based on 16s rrna gene sequences: description of arcanobacterium phocae sp. nov., arcanobacterium bernardiae comb. nov., and arcanobacterium pyogenes comb. nov.a systematic phylogenetic analysis of the genus actinomyces was performed. the 16s rrna gene sequences of 13 actinomyces species, an unnamed actinomyces strain (atcc 49338), and an actinomyces-like isolate from sea mammals were determined. comparative sequence analysis with closely related taxa revealed phylogenetic diversity and internal structure within the genus actinomyces. in addition, some members of other genera (viz., the genera arcanobacterium, mobiluncus, and rothia) were shown to be p ...19978995800
