The fungal pathogen Candida albicans is an opportunistic fungal pathogen that causes oral and vaginal mucosal infections as well as systemic disease. The ability of C. albicans to adhere to host surfaces is positively correlated with its pathogenicity. We prepared a polyclonal anti-Candida albicans antibody in chicken egg yolk (anti-C. albicans IgY) and investigated its in vitro effectiveness i...
Treponema denticola has been recognized as an important oral pathogen of the "red complex" bacterial consortium that is associated with the pathogenesis of endodontal and periodontal diseases. However, little is known about the virulence of T. denticola due to its recalcitrant genetic system. The difficulty in genetically manipulating oral spirochetes is partially due to the lack of antibiotic ...
Cryptobacterium curtum Nakazawa etal. 1999 is the type species of the genus, and is of phylogenetic interest because of its very distant and isolated position within the family Coriobacteriaceae. C. curtum is an asaccharolytic, opportunistic pathogen with a typical occurrence in the oral cavity, involved in dental and oral infections like periodontitis, inflammations and abscesses. Here we desc...
Bacterial, viral and parasitic zoonotic pathogens that transmit via the fecal-oral route have a major impact on global health. However, the mechanisms underlying the emergence of such pathogens from the animal reservoir and their persistence in the human population are poorly understood. Here, we present a framework of human-to-human transmission of zoonotic pathogens that considers the factors...
Antimicrobial streamlining is the practice of converting a broad-spectrum empirical regimen to therapy with either a single, narrow-spectrum parenteral agent or an oral agent as soon as possible. This practice results in many benefits for the patient and the hospital. When intravenous catheters can be removed early, the frequencies of catheter-associated bacteremias and phlebitis are reduced, t...
BACKGROUND Tannases are tannin-degrading enzymes that have been described in fungi and bacteria as an adaptative mechanism to overcome the stress conditions associated with the presence of these phenolic compounds. RESULTS We have identified and expressed in E. coli a tannase from the oral microbiota member Fusobacterium nucleatum subs. polymorphum (TanBFnp). TanBFnp is the first tannase iden...
conclusions finally, it can be suggested that the extracts of this plant be applied as antimicrobial agents against these pathogens, particularly in biofilm forms. results the results showed that the a. sativum l. extract discs did not have any zone of inhibition for the tested bacteria. however, the mic values of a. sativum l. extracts (0.078 - 2.5 mg/ml) confirmed the high ability of these ex...

different species of streptomyces are common in most types of soil. some certain species are plant pathogenic especially on potato. this study was conducted to evaluate genetic diversity among some local streptomyces spp. strains isolated from soil and infected tubers in potato farms in northwest of iran. repetitive dna elements (box, eric and rep) as genetic markers were used for diversity stu...
background : a large number of plants are used for treatment of diseases because of their antimicrobial activities. this study aims to investigate the antimicrobial effects of some plants on the food pathogenic bacteria. methods : plant extracts were obtained using the rotary system, the minimum inhibitory concentration (mic) by diluting method against bacteria was determined. results : ...
