Tonic water added is known as bitter lemon or bitter lime, respectively. The quinine in tonic water will fluoresce under ultraviolet light. In fact, the sensitivity of quinine to ultraviolet light is such that it will appear visibly fluorescent in direct sunlight. Tonic water Tonic water (or Indian tonic water) is a carbonated soft drink in which quinine is dissolved. Originally used as a prophylactic against malaria, tonic water usually now has a significantly lower quinine content and is consumed for its distinctive bitter flavor. It is often used in mixed drinks, particularly in gin and tonic. Quinine was added to the
Human genetic resistance to malaria and loss of the Gerbich antigen and the Duffy antigen. These names refer to various proteins, enzymes, and the shape or function of red blood cells. The potent effect of genetically controlled innate resistance is reflected in the probability of survival of young children in areas where malaria is endemic. It is necessary to study innate immunity in the susceptible age group (younger than four years), because in older children and adults, the effects of innate immunity are overshadowed by those of adaptive immunity. It is also necessary to study populations in which random use of antimalarial drugs does not
