Resumo:A taxonomic study using a polyphasic approach 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 % 16S rRNA gene sequence similarity), Arcanobacterium phocisimile (97.8 %), Arcanobacterium phocae (97.7 %), Arcanobacterium haemolyticum (97.4 %), Arcanobacterium hippocoleae (96.6 %), Arcanobacterium pinnipediorum (96.4 %) and Arcarnobacterium pluranimalium (95.4 %). DNA-DNA hybridization values between strain 647T and Arcanobacterium canisDSM 25104T were very low, 13.4 % (reciprocal 15.9 %). The genomic DNA G+C content of strain 647T was 58.7 mol%. The presence of the major menaquinone MK-9(H4) supported the affiliation of this strain to the genus Arcanobacterium. The polar lipid profile consisted of the major components diphosphatidylglycerol, phosphatidylcholine and an unidentified phosphoglycolipid. The results of physiological and biochemical testing clearly distinguished the unknown bacterium from other species of the genus Arcanobacterium. Based on these tests, it is proposed that the unknown bacterium should be classified as a representative of a novel species of the genus Arcanobacterium named Arcanobacterium wilhelmaesp. nov. The type strain is 647T (=DSM 102162T=LMG 29418T).

Resumo:BACKGROUND: 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. ANIMALS: Three mink from each of three different mink farms (A-C) with postvaccination skin wounds at the vaccination site and six mink from an unaffected mink farm (D) that had used the same vaccine batch and vaccination site (hind leg). METHODS AND RESULTS: All mink from farms A-C had severe necrotizing to necropurulent dermatitis where they were vaccinated intramuscularly in the hind leg. ABP was the sole bacterium cultured from six of nine wounds. Using 16S-23S rDNA intergenic spacer region and BOX-PCR, the ABP isolates from these wounds were indistinguishable from isolates originating from several cases of FENP. CONCLUSIONS AND CLINICAL IMPORTANCE: This is the first report of FENP-like lesions at the site of vaccination, in the days following the procedure, associated with ABP. At farms with FENP vaccination, procedures should be considered carefully.

Título:Survival of Streptococcus suis, Streptococcus dysgalactiae and Trueperella pyogenes in dry-cured Iberian pork shoulders and loins.

Idioma:eng
Resumo:Dry-cured hams, shoulders and loins of Iberian pigs are highly appreciated in national and international markets. Salting, additive addition and dehydration are the main strategies to produce these ready-to-eat products. Although the dry curing process is known to reduce the load of well-known food borne pathogens, studies evaluating the viability of other microorganisms in contaminated pork have not been performed. In this work, the efficacy of the dry curing process to eliminate three swine pathogens associated with pork carcass condemnation, Streptococcus suis, Streptococcus dysgalactiae and Trueperella pyogenes, was evaluated. Results of this study highlight that the dry curing process is a suitable method to obtain safe ready-to-eat products free of these microorganisms. Although salting of dry-cured shoulders had a moderate bactericidal effect, results of this study suggest that drying and ripening were the most important stages to obtain dry-cured products free of these microorganisms.

Resumo:Arcanobacterium hemolyticum (A.haemolyticum) is a gram-positive bacillus. Man is the primary environmental reservoir. It is essentially an opportunistic pathogen in immunocompromised patients and may be responsible for infections of the skin and pharynx in healthy subjects, especially in children and adolescents. It can cause superinfections of chronic ulcers, but occasionally it causes invasive infections. Its isolation from culture samples is always difficult because it simulates many bacteria to which it is often associated in pathological products. There are not recommendations concerning the study of its antibiotics sensitivity. Arcanobacterium Bacteremia are rare to our knowledge, only sixteen case reports have been described in the literature. We here report another case of a patient with A.haemolyticum bacteremia secondary to superinfection of gluteal eschars.

Resumo: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 FENP. Different inoculation methods were tested to study possible routes of transmission. Typical signs, and gross- and histopathological findings for FENP were detected when naïve mink were infected with the tissue extract of mink with FENP, using a subcutaneous/ intradermal infection route. Edema, hemorrhage, necrosis and pus formation were detected in the infection site. A pure culture preparation of A. phocae alone or concurrently with the novel Streptococcus sp. caused severe acute signs of lethargy, apathy and anorexia and even mortality. The histopathological findings were similar to those found in naturally occurring cases of FENP. In contrast, the perorally infected mink presented no clinical signs nor any gross- or histopathological lesions. This study showed that A. phocae is able to cause FENP. The study also indicated that predisposing factors such as the environment, the general condition of the animals, temperature and skin trauma contribute to the development of the disease.

Resumo:BACKGROUND: An adult male galago (Otolemur garnettii) presented for fight wounds following pairing for breeding. Treatment was symptomatic with recovery. Following resolution, the animal re-presented and died, despite additional treatment. METHODS: Necropsy, histopathology, bacterial cultures, and 16S RNA sequencing. RESULTS: A large intrathoracic/intra-abdominal abscess due to Trueperella pyogenes was found at necropsy. CONCLUSIONS: T. pyogenes should be considered in abscesses/wounds of galagos.

Idioma:eng
Resumo:In the present study 28 Trueperella pyogenes strains isolated from various origins could successfully be identified with a newly designed loop-mediated isothermal amplification (LAMP) assay based on gene cpn60 encoding chaperonin. No cross reaction could be observed with control strains representing four species of genus Trueperella and seven species of closely related genus Arcanobacterium. The present cpn60 LAMP assay might allow a reliable and low cost identification of T. pyogenes also in laboratories with less specified equipment.

Resumo:The objectives of this study were to report the prevalence of Escherichia coli and Trueperella pyogenes in the uterus of postpartum dairy cows before the onset of postpartum metritis (PPM) and to quantify their association with subsequent occurrence of PPM, to quantify the association between the presence of genes encoding E. coli virulence factors (VF) and PPM, and to determine the accuracy of using early postpartum uterine bacteriology results (bacteria and VF) to identify cows at risk of PPM. A prospective cohort study was conducted on 3 commercial dairy farms. Uterine swabs were collected from 371 Holstein dairy cows (3 commercial herds) at 1 to 7d in milk and submitted to the laboratory for identification of E. coli, T. pyogenes, and E. coli VF. A total of 40 VF were tested using the radioactive probe hybridization method. Postpartum metritis was defined as the presence of a fetid watery red-brown uterine discharge, associated with fever (rectal temperature >39.5°C), and systemic signs of illness (dullness, reduced appetite, and milk production). Surveillance of PPM was done by trained farmers blinded to laboratory results and cows were followed until 21d in milk. Statistical analyses were conducted using 2×2 tables and mixed logistical regression models. Prevalences of E. coli, T. pyogenes, and PPM were 42, 34, and 15%, respectively. A total of 32 VF were found in E. coli isolates. Most prevalent VF were extraintestinal pathogenic genes such as fimH (89%), hlyE (87%), and iss (70%). Cows positive for intrauterine E. coli were 3.2 times more likely to have subsequent PPM compared with bacteriologically negative cows. Cows with VF hra1 in their uterus were 2.7 times more likely to have PPM than cows positive for E. coli and negative for hra1 and 5.9 times more likely than bacteriologically negative cows. Cows with VF kpsMTII in their uterus were 3.2 times more likely to have PPM than cows positive for E. coli and negative for kpsMTII and 6.2 times more likely than bacteriologically negative cows. Using E. coli, hra1, and kpsMTII as predictors for subsequent PPM, positive predictive values were 23, 31, and 42%, respectively, whereas the negative predictive values were 91, 80, and 78%, respectively. Overall, these results showed that E. coli and some VF were associated with PPM.

Resumo:Trueperella bernardiae is a Gram-positive coryneform bacilli which role as human pathogen is unknown because it has been usually considered a contaminant. Furthermore its identification by biochemical test was difficult. We describe a prosthetic joint infection in a women who years ago underwent a total knee replacement with superinfection and necrosis of the patellar tendon as major complications. In the sample of synovial fluid collected grew a gram-positive bacilli which was identified by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) as T. bernardiae. The patient was treated with ciprofloxacin and currently preserves the prosthesis without signs of infection.

Idioma:eng
Resumo:In the present study, three Arcanobacterium pluranimalium strains isolated from bovine milk samples of three cows of three farms (two cows with subclinical mastitis) could successfully be identified by phenotypical investigations, by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) analysis and genotypically by sequencing the molecular targets 16S rDNA, 16S-23S rDNA intergenic spacer region (ISR), the ß subunit of bacterial RNA polymerase encoding gene rpoB, the glyceraldehyde 3-phosphate dehydrogenase encoding gene gap, the elongation factor tu encoding gene tuf, and the pluranimaliumlysin encoding gene pla. The latter could also be identified by a loop-mediated isothermal amplification (LAMP) assay. The presented phenotypic and genotypic approaches might support the identification of A. pluranimalium in future and might help to understand the role this species plays in bovine mastitis.
