Cholera, whooping cough, diphtheria and bacillary dysentery: bacterial diseases.

Cholera: provoked by Vibrio cholerae, causes whitish diarrhea due to the release of toxins in the small intestine, causing the release of water and mineral salts by the cells present there. This factor can cause death from renal failure, approximately one day after the onset of symptoms, if the proper treatment is not applied. The infection is caused by ingestion of water and food contaminated by the feces of affected people.

Whooping cough: The Bordetella pertussis it is responsible for the intense coughing. As these are successive, they leave the individual without breathing until they stop, causing that, when breathing is resumed, it reproduces a very characteristic squeaking sound. This bacteria is transmitted by inhaling droplets of saliva containing the transmitting agent, usually eliminated in the speech, coughing or sneezing of infected people. There is vaccine against pertussis.

Diphtheria (croup): affecting mainly children, it is transmitted by inhalation of respiratory secretions containing the bacteria

Corynebacterium diphteriae. Thanks to the toxin it releases, the patient has organs of the respiratory system, such as the tonsils and pharynx, affected. For this reason, it can cause death from suffocation. Fever and difficulty speaking and swallowing - mainly due to a membrane that appears in the throat - are characteristic manifestations. There is preventive vaccine.

Do not stop now... There's more after the advertising ;)

bacillary dysentery (shigellosis): caused by bacteria of the genus Shigella, it causes watery and severe diarrhea due to the action of its toxins, released in the small intestine. Its infection is caused by ingestion of water or food contaminated by the feces of sick people. It can cause dehydration and, in more severe cases, seizures.
