The mechanism of light stimulation of active K and Cl influx and active Na efflux, in Hydrodictyon africanum has been investigated using different wavelengths of red light and different gas mixtures, and the inhibitors DCMU and CCCP. The active Cl influx requires photosystem 2, since its relative quantal efficiency falls with increasing wavelength of red light, and it is as sensitive to the inh...

Tuberculosis (TB) is an infectious and transmissible disease caused by Mycobacterium tuberculosis and closely related mycobacterial species (M. bovis, M. africanum, and M. microti). These species, obligate pathogens, compose what is known as the M. tuberculosis complex. Nontuberculous mycobacterial (NTM) species are mycobacterial species other than those belonging to the Mycobacterium tuberculo...
