- Neisseria meningitidis (meningococcus): It produces meningococcal meningitis upon entering the bloodstream. It is highly contagious and deadly.
- Streptococcus pneumoniae (pneumococcus): It is the most common cause of bacterial meningitis in infants and children. It mostly causes pneumonia, ear or sinus infection.
- Haemophilus influenzae (hemophilus): It is present in the nose and throat of a person, which does not cause any problems. But if it spreads to other parts of the body, it can cause alarm.
- Listeria monocytogenes (listeria): We can find it in processed meats, unpasteurized cheeses and hot dogs. Most cases are due to the ingestion of contaminated food. Another way of contagion is during pregnancy, since listeria can cross the placental barrier and be fatal to the baby.
