Impetigo: is caused by Staphylococcus aureus or Streptococcus pyogenes. Streptococcus infection causes small pus-filled lesions that later form scabs. On the other hand, when Staphylococcus are responsible, thin-walled blisters appear that, when they break, leave the skin inflamed and moist. These bacteria penetrate the skin through preexisting wounds or cracks, through direct contact with the lesions of affected people, objects or utensils contaminated by these.
leptospirosis: a Leptospira interrogans is responsible for this disease, being released in the urine of animals such as rats and dogs. Contact with water, soil, food and objects contaminated by bacteria promotes human contagion, with symptoms including fever and headache, muscles and joints. Skin lesions may appear and also affect lungs, kidneys and liver, with risks of leading the individual to death if not treated in time. There are vaccines only for use in animals, such as dogs, cattle and swine, and its annual application is recommended. Sick people do not transmit the disease to other people.
Meningitis: in this disease, whose responsible bacteria are Neisseria meningitidis, Hemophilus influenzae or Streptococcus pneumoniae; the affected individual usually experiences severe headache, fever, and neck stiffness due to involvement of the meninges. Vomiting episodes are also common. It is transmitted by inhaling droplets of respiratory secretions from sick people. Medical help is essential, as it can lead to death. There is preventive vaccine.
Tetanus: deep skin lesions, when coming in contact with spores of the Clostridium tetani, cause muscle contractions capable of causing death by asphyxia due to the action of their toxin - if the treatment for the disease is not done in a timely manner. The use of vaccine and serum are important measures to avoid the problems caused by this micro-organism.
Do not stop now... There's more after the advertising ;)
