A failure to turn off GTP-activated Ga has dire consequences. For example, in the disease cholera, cholera toxin produced by the bacterium Vibrio cholerae binds to Ga and prevents GTP hydrolysis, resulting in the continued excretion of sodium and water into the gut. 

In addition to these microorganisms, three other types are readily destroyed Enteric vegetative bacteria (Eberthella, Shigella, Salmonella and Vibrio species) Worms such as the block flukes (Schistosoma, species) Viruses (for example, the virus of infectious hepatitis). Each of these groups of organisms differs in its reaction with chlorine. 

Vibrio (i) Curved, rod-shaped bacterial cell, (ii) Bacterium of the genus Vibrio. Virion Virus particle the virus nucleic acid surrounded by protein coat and in some cases other material. 

To identify the specific aldehyde that is actually involved in the light-emitting reaction of living luminous bacteria, Shimomura et al. (1974a) extracted and purified the aldehyde from 40 g each of the bacterial cells of P. phosphoreum, Achromobacter (Vibrio or Photobacterium) fischeri, and an aldehydeless mutant of A. fischeri. The aldehyde fractions were purified, and then oxidized with Tollens reagent (silver oxide dissolved in ammonia) to convert the CHO group into the COOH group. Then the acids obtained were analyzed by mass spectrometry. The results indicated that P. phosphoreum had contained a mixture of aldehydes dodecanal (5%), tetradecanal (63%) and hexadecanal (30%), as shown in Table 2.2. Thus, tetradecanal was clearly predominant in... 

Ulitzer and Hastings, 1979 Riendeau and Meighen, 1980). The chemical structure of the autoinducer of P. (Vibrio) fischeri was determined by Eberhard et al. (1981) to be an acylhomoserine lactone (1), shown below. The autoinducer of Vibrio harveyi was found to be another acylhomoserine lactone (2) by Cao and Meighen (1989).
