Antibiotics are medications used to kill or prevent the spread of disease causing bacteria in the body. There are two types of antibiotics which manage infectious diseases differently: 1. Bactericidal Antibiotics: this is when the antibiotic completely kills off the Bacteria. It does this by damaging or interfering with the bacteria’s cell contents or wall. An example of this type of antibiotic is Penicillin which is in fact the first type of antibiotic to be discovered. 2. Bacteriostatic Antibiotics:

Observations: When Malaria is present and infects red blood cells‚ parasites can infect cells carrying defective hemoglobin which may result in death. Allele frequency changes over time depending on the pressures or circumstances facing a particular population. African populations are especially impacted by both malaria and sickle cell anemia. Depending on the impacted population‚ allele frequency often shifts and well suited organisms are likely to survive and allele frequencies can increase
