Corynebacterium pseudotuberculosis و نقش بیماریزایی آن در حیوانات و انسان

Corynebacterium diphtheriae, Corynebacterium ulcerans and Corynebacterium pseudotuberculosis—General Aspects

V. A. de. C. Azevedo Departmento de Biologia, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais, Belo Horizonte, MG, Brazil Abstract Corynebacterium diphtheriae, Corynebacterium ulcerans and Corynebacterium pseudotuberculosis are potentially diphtheria toxin-producing microorganisms related to different infectious processes involving both human and animal hosts. This chapte...

Degenerate Four Wave Mixing in Photonic Crystal Fibers

In this study, Four Wave Mixing (FWM) characteristics in photonic crystal fibers are investigated. The effect of channel spacing, phase mismatching, and fiber length on FWM efficiency have been studied. The variation of idler frequency which obtained by this technique with pumping and signal wavelengths has been discussed. The effect of fiber dispersion has been taken into account; we obtain th...

omas, and is limited to the cranial-spinal axis, without systemic disease. A known high-risk group for PCNSL comprises patients with immunosuppression, but in the last 15-20 years there has been a threefold increase in patients who are immunocompetent, and the causative factors for this increase are unknown [l-31. PCNSL commonly presents as a rapidly space-occupying lesion. Rarely, patients wit...

An improved Corynebacterium pseudotuberculosis vaccine for sheep.

Extensive experiments in mice confirmed that the immunogenicity of a Corynebacterium pseudotuberculosis vaccine could not be significantly improved with the use of various adjuvants. Immunity against C. pseudotuberculosis likewise could not be enhanced by incorporating various immunostimulants into the vaccine or by the use of live vaccines. However, a combination of aluminium hydroxide gel and...

Corynebacterium ulcerans and Corynebacterium pseudotuberculosis responses to DNA probes derived from corynephage beta and Corynebacterium diphtheriae.

Strains of Corynebacterium ulcerans and Corynebacterium pseudotuberculosis (Corynebacterium ovis) were examined for the production of diphtheria toxin. A majority of C. ulcerans strains (25 of 37) and 1 C. pseudotuberculosis strain (1 of 14) gave a positive Elek test for diphtheria toxin, and for all strains but 1, production of diphtheria toxin was inhibited at the same level of Fe2+ as was th...
