These findings tell us that many people who eat at fast-food restaurants may not be making informed choices because they don't know how many calories they're consuming, Block said. None of the chains involved in the study included nutritional information on their menus, the researchers pointed out.
Diphtheria is caused by the c orynebacterium diphtheriae bacterium. Itâs most commonly spread through person-to-person contact or contact with items that have the bacteria on them.Coming into contact with items such as an infected personâs cup or used tissue can transfer the bacteria.he vaccine for diphtheria is given in a single shot (along with vaccines for pertussis and tetanus) that is called DTaP. The DTaP vaccine is administered in a series at 2, 4, and 6 months of age, and then again at around 1 and 4 years of age.
Back to Top Causes. Diphtheria spreads through respiratory droplets (such as from a cough or sneeze) of an infected person or someone who carries the bacteria but has no symptoms. The bacteria most commonly infects your nose and throat. The throat infection causes a gray to black, tough, fiber-like covering, which can block your airways. In some cases, diphtheria infects your skin first and causes skin lesions. Once infected, the bacteria make dangerous substances called toxins. The toxins spread through your bloodstream to other organs, such as the heart and brain, and cause damage. Because of widespread immunization (vaccination) of children, diphtheria is now rare in many parts of the world.
