Acceleration of tetrazolium reduction by bacteria.
Conditions were assessed which would permit more rapid recognition of bacterial growth than has been previously reported using tetrazolium salts. Microtitration trays were used. 2-(p-Iodophenyl)-3(p-nitrophenyl)-5-phenyltetrazolium chloride is rapidly reduced by respiring cells in tissue homogenates but is more toxic than other tetrazoliums when added to growing bacterial cultures. Phenazine me...
متن کاملNitroblue tetrazolium test in experimental syphilis.
The reduction of nitroblue tetrazolium (NBT) by phagocytic leucocytes in peripheral blood has been examined in rabbits injected intratesticularly with Treponema pallidum, T. pallidum-free supernatant of orchitic testes, or normal rabbit testes supernatant. A significant (P less than 0.01) increase in NBT reduction was observed only in the infected animals.
متن کاملThe Chemistry of Formazans and Tetrazolium Salts
ÖZ E T Bu çalışmada tetrazolyum tuzları ve formazanların yapıları tanımlanmıştır. Ayrıca formazan-tetrazolyum sistemlerinin önemi ve kullanım alanları açıklanmıştır. Formazanların sahip oldukları conjugate p-system kaynaklanan tautomerleşme özellikleri ve geometrik izomerleri incelenmiştir. Bu bileşiklerin en yaygın kullanılan sentezleri ve yapılarının açıklanmasında önemli olan UV-visible, IR ...
متن کاملDetection of Fermentative Variants with Tetrazolium.
While trying to develop methods for finding dehydrogenase mutants, we found tetrazolium (triphenyl tetrazolium chloride) to be useful for detecting fermentative variants. This indicator has the advantage that the nonfermenting variants are stained a deep red whereas the fermenters and the background are neutral. For example, cultures of Escherichia coli K-12 were spread on nutrient agar plates ...
متن کاملTetranitro-blue Tetrazolium Reduction in Bacillus Subtilis
In order to decide whether in the bacterial cell the enzymes of the respiratory chain are located in "particulate elements" (1) or in the plasma membrane (2) we investigated the reduction of potassium tellurite in Gram-positive and Gram-negative bacteria. For the first time in 1962 (3), and in more detail in 1964 (4), we reported that with Bacillus subtilis we had found that reduction products ...
