The performance of the dermatophyte test medium (DTM) RapidVet-D was assessed using hair samples collected from experimentally infected guinea pigs. Three dermatophyte species were included in the study: Microsporum canis, Trichophyton mentagrophytes and Trichophyton equinum. DTM substrates were inoculated with infected hairs and scales, incubated at 18, 21, 24, 27 or 37 degreesC and examined daily for 15 days. The rapidity of colour change was clearly related to the incubation temperature and to the number of infected hairs deposited on the reactive substrates. With the optimum incubation temperature 27 degreesC, a systematic colour change could be observed only a few days post-inoculation: 3 days with M. canis infected hairs, 4 days with T. equinum and 5 days with T. mentagrophytes.

Abstract7Li NMR is carried out between 150 and 450 K in Li‐deficient chlorides with LiCl‐type or the related Suzuki‐type structure. Diffusive motion of Li+ ions is observed and the analysis of experimental data for Li1−2xMgxCl with x = 0.01 shows that the introduction of 1% vacancies into the lattice enhances the Li+ mobility by a factor of 30 at 440 K. By increasing the number of vacancies, the activation energy decreases down to 0.38 eV for ordered Li6VCl8 which contains 12.5% vacancies and even to 0.25 eV for the disordered phase corresponding to the same composition.

7Li resonance has been carried out at 7.5, 11, 21 and 29 MHz on the Suzuki type-phase Li6VCl8. The spectra appear to be rather complex and strongly frequency dependent. From the thermal evolution of the isotropic and the anisotropic shifts one obtains the spin densities transferred to the 2s orbital of Li+, fs = 0.37% and to the 2p orbitals, fσ − fπ = 3.10%.

Ionic conductivity of phases with general formulaLixLn1/3Nb1−xTixO3 (Ln =La, Nd)has been determined for materials with a small value ofx, i.e., in composition range with aLn1/3NbO3perovskite related structure. The possible influence on the transport properties of the 2D character of the vacancy sublattice has been investigated by a NMR study on Li0.05Nb0.95Ti0.05O3.

Three kinds of intermediate solid-solutions appear in the phase diagrams of the binary systems LiClMCl2. They correspond to various distributions of ctions and vacancies in the available sites of a f.c.c. of chlorine atoms. The ionic motion of Li+ ions in the highly deficient solid-solutions has been concurrently investigated by NMR techniques and conductivity measurements.
