| first detection of corynebacterium ulcerans producing a diphtheria-like toxin in a case of human with pulmonary infection in the rio de janeiro metropolitan area, brazil. | the frequency and severity of human infections associated with corynebacterium ulcerans appear to be increasing in different countries. here, we describe the first c. ulcerans strain producing a diphtheria-like toxin isolated from an elderly woman with a fatal pulmonary infection and a history of leg skin ulcers in the rio de janeiro metropolitan area. | 2008 | 18660996 |
| corynebacterium ulcerans isolated from an asymptomatic dog kept in an animal shelter in the metropolitan area of rio de janeiro, brazil. | corynebacterium ulcerans was isolated from nares of one asymptomatic dog kept in an animal shelter in the metropolitan area of rio de janeiro, brazil. the rna polymerase beta subunit-encoding gene was sequenced to confirm the species identity. c. ulcerans strains producing phospholipase d, but not diphtheria toxin, are able to cause severe disease in humans, such as pneumonia and granulomatous nodules in pulmonary tissues. the infection rate varies really widely by region, probably because of th ... | 2010 | 20055577 |
| Corynebacterium ulcerans diphtheria: an emerging zoonosis in Brazil and worldwide. | The article is a literature review on the emergence of human infections caused by Corynebacterium ulcerans in many countries including Brazil. Articles in Medline/PubMed and SciELO databases published between 1926 and 2011 were reviewed, as well as articles and reports of the Brazilian Ministry of Health. It is presented a fast, cost-effective and easy to perform screening test for the presumptive diagnosis of C. ulcerans and C. diphtheriae infections in most Brazilian public and private laborat ... | 2011 | 22124745 |
| corynebacterium ulcerans isolates from humans and dogs: fibrinogen, fibronectin and collagen-binding, antimicrobial and pfge profiles. | corynebacterium ulcerans has been increasingly isolated as an emerging zoonotic agent of diphtheria and other infections from companion animals. since pets are able to act as symptomless carriers, it is also essential to identify virulence potential for humans of these isolates. in this work the ability of c. ulcerans to bind to fibrinogen (fbg), fibronectin (fn) and type i collagen as well the genetic relationship among strains isolated from human and asymptomatic dogs in rio de janeiro (brazil ... | 2014 | 24281735 |
