Bacteria are microscopic unicellular organisms which are formed by prokaryotic cells. Although we sound so negative, these microorganisms are essential for life on our planet, because thanks to them perform many of the essential functions of ecosystems.

They are of vital importance for both human as well be worse, but in this case, we will stop only with those that are harmful to our health.

Below are several diseases caused by bacteria are detailed, causing symptoms in the patient, which bacteria are involved, the transmission mode and the usual vaccination schedule:

Diseases caused by bacteria


This disease is caused by the bacterium Clostridium botulinum.

Bacteria may enter the body through wounds or could live in food that has been improperly canned or poorly maintained.

Once incubated symptoms that could arise are:

  • Abdominal cramps.

  • Difficulty swallowing and speaking
  • Double vision
  • Sickness
  • Vomiting
  • Weakness with paralysis (equal on both sides of the body)

It is spread by:


Improperly canned or preserved food


It cured with a drug to combat bacteria (botulinum antitoxin).


This disease is caused by the bacterium Vibrio cholera.

Rarely, cholera is transmitted by person to person contact.

The symptoms are:

  • Vomiting
  • Diarrhea
  • Dehydration

It is spread by:

Contaminated food and water


Name: BS-WC.

The usual pattern for vaccination would be:

A dose of 50ml in children 2-5 years

A dose of 100ml in over 5 years

This disease is caused by the streptococcus bacteria.

Usually it affects children.

Once incubated symptoms that could arise are:

Viral infections that usually gets better without treatment.

Chemical irritation

Drug allergies





Vaccines routinely recommended for children or older than 65 years are:

Hib (Haemophilus influenzae type b)

PCV7 (Pneumococcal conjugate)

Meningococcal vaccine (MCV4) is recommended for:

Adolescents 11 to 12 years, with a booster shot between 16 and 18 years.

Children 2 years and older with problems with the immune system

People traveling to countries at risk

Bacterial pneumonia

  • Tremors

It is spread by:

Air (coughing, sneezing)

By close contact with a person who is a carrier or asymptomatic, that is, they are not sick but have bacteria in your body and can transmit it to susceptible and vulnerable.


Name: PPSV (Pneumococcal polysaccharide vaccine).

– Pneumococcal.

– Polysaccharide.

– Vaccine.

The usual pattern for routine immunization is currently:
