1. 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

2. 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

3. 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

4. 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

5. 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

6. 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

7. 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

8. Potential pathogenic role of aggregative- adhering Corynebacterium diphtheriae of different clonal groups in endocarditis
Invasive diseases caused by Corynebacterium diphtheriae have been described increasingly. Several reports indicate the destructive feature of endocarditis attributable to nontoxigenic strains. However, few reports have dealt with the pathogenicity of invasive strains. The present investigation demonstrates a phenotypic trait that may be used to identify pote

9. Antimicrobial resistance among Brazilian Corynebacterium diphtheriae strains
The increasing problems with multidrug resistance in relation to Corynebacterium, including C. diphtheriae, are examples of challenges confronting many countries. For this reason, Brazilian C. diphtheriae strains were evaluated by the E-Test for their susceptibility to nine antibacterial drugs used in therapy. Resistance (MIC < 0.002; 0.38 µg/ml) to penicil

10. Prevalence of diphtheria and tetanus antibodies and circulation of Corynebacterium diphtheriae in São Paulo, Brazil
The introduction of routine vaccination against tetanus and diphtheria in Brazil has decreased the incidence and changed the epidemiology of both diseases. We then investigated the prevalence of Corynebacterium diphtheriae carrier status and diphtheria and tetanus immunity in São Paulo, Brazil. From November 2001 to March 2003, 374 individuals were tested f

11. Prevalência de bactérias patogênicas "não-orais" no biofilme dental subgengival de pacientes com periodontite crônica
Apesar da extensa literatura sobre a associação de bactérias orais e doenças sistêmicas, tem se dado pouca atenção à cavidade oral como um reservatório de bactérias patogênicas "não-orais". A microbiota oral é constituída de mais de 300 espécies bacterianas já caracterizadas, além de organismos não cultiváveis que vêm sendo descobertos at

12. Diphtheria remains a threat to health in the developing world: an overview
Changes in the epidemiology of diphtheria are occurring worldwide. A large proportion of adults in many industrialized and developing countries are now susceptible to diphtheria. Vaccine-induced immunity wanes over time unless periodic booster is given or exposure to toxigenic Corynebacterium diphtheriae occurs. Immunity gap in adults coupled with large numb
