1. Tricuspid Valve Repair with Autologous Pericardium in a Patient with Infective Endocarditis
Abstract Infective endocarditis is a rather uncommon disease, but it has significant mortality rates in the pediatric population (5% to 10%). We report a case of an infant patient with multiple vegetation in the tricuspid valve secondary to infective endocarditis caused by Corynebacterium diphtheriae. A tricuspid valvuloplasty was performed with a fenestrate

2. Septicemia in an immunocompetent adult in the Czech Republic caused by Corynebacterium diphtheriae nontoxigenic strain biotype mitis: emergence of invasive cases in Western Europe
ABSTRACT Dengue has been a significant public health problem in Colombia since the simultaneous circulation of the four dengue virus serotypes. The replicative fitness of dengue is a biological feature important for virus evolution and contributes to elucidating the behavior of virus populations and viral pathogenesis. However, it has not yet been studied in

4. Genomic analysis of a nontoxigenic, invasive Corynebacterium diphtheriae strain from Brazil
We report the complete genome sequence and analysis of an invasive Corynebacterium diphtheriae strain that caused endocarditis in Rio de Janeiro, Brazil. It was selected for sequencing on the basis of the current relevance of nontoxigenic strains for public health. The genomic information was explored in the context of diversity, plasticity and genetic relat

5. Corynebacterium diphtheriae putative tellurite-resistance protein (CDCE8392_0813) contributes to the intracellular survival in human epithelial cells and lethality of Caenorhabditis elegans
Corynebacterium diphtheriae, the aetiologic agent of diphtheria, also represents a global medical challenge because of the existence of invasive strains as causative agents of systemic infections. Although tellurite (TeO32-) is toxic to most microorganisms, TeO32--resistant bacteria, including C. diphtheriae, exist in nature. The presence of TeO32--resistanc

6. Multiplex polymerase chain reaction to identify and determine the toxigenicity of Corynebacterium spp with zoonotic potential and an overview of human and animal infections
Corynebacterium diphtheriae, Corynebacterium ulcerans and Corynebacterium pseudotuberculosis constitute a group of potentially toxigenic microorganisms that are related to different infectious processes in animal and human hosts. Currently, there is a lack of information on the prevalence of disease caused by these pathogens, which is partially due to a red

7. A fatal case of urosepsis due to Corynebacterium riegelii
Corynebacterium species other than Corynebacterium diphtheriae rarely cause infections in human but rather reside in flora, however they have been reported to cause opportunistic infections in both immunocompromised and immunecompetent patients. Here we report for the first time a case of an elderly female patient presenting with a fatal urosepsis caused by

8. Influência de pré-tratamentos de células epiteliais com penicilina e eritromicina na aderência e na viabilidade intracelular de Corynebacterium diphtheriae / Influence of epithelial cells pre-treatment with penicilin and erythromycin in adherence and intracellular viability of Corynebacterium diphtheriae
Diphtheria is a syndrome caused by Toxigenic Corynebacterium diphtheriae. Although immunization programs have kept diphtheria under control in the great majority of developed countries, the disease remains endemic in many parts of the world, especially in individuals partially immunized to diphtheria toxoid. Additionally, an increase in the number of cases o

9. Difteria pelo Corynebacterium ulcerans: uma zoonose emergente no Brasil e no mundo
O artigo revisa a literatura sobre a emergência de infecções humanas causadas por Corynebacterium ulcerans em diversos países, incluindo o Brasil. Foi realizada análise de artigos publicados entre 1926 e 2011 nas bases Medline/PubMed e SciELO, bem como artigos e informes do Ministério da Saúde. Apresenta-se um esquema de triagem, rápido, econômico e

10. Papel das hemaglutininas 67-72p de Corynebacterium diphtheriae na ligação a proteínas plasmáticas, superfícies celulares, invasão e indução de apoptose / Participation of hemagglutinin 67-72p of corynebacterium diphtheriae in binding to plasma proteins, cells surfaces, invasion and induction of apoptosis
Corynebacterium diphtheriae pode ser isolado tanto de quadros de difteria clássica, quanto de infecções sistêmicas, como endocardite. O fibrinogênio (Fbn) e a fibronectina (Fn) são glicoproteínas presentes na matriz extracelular de tecidos conjuntivos. A influência destas proteínas na patogênese das infecções locais e invasivas causadas por C. di

11. Fibrinogen binds to nontoxigenic and toxigenic Corynebacterium diphtheriae strains
The production of fibrinous exudates may play an important role in determining the outcome of bacterial infection. Although pseudomembrane formation is a characteristic feature of diphtheria, little is known about the fibrinogen (Fbn)-binding properties of Corynebacterium diphtheriae strains and the influence of the gene that codes for diphtheria toxin (tox

12. Expression and purification of the immunogenically active fragment B of the Park Williams 8 Corynebacterium diphtheriae strain toxin
The construction of a hexahistidine-tagged version of the B fragment of diphtheria toxin (DTB) represents an important step in the study of the biological properties of DTB because it will permit the production of pure recombinant DTB (rDTB) in less time and with higher yields than currently available. In the present study, the genomic DNA of the Corynebacte
