Biological basis of Gram staining
- Bacteria have both of cell wall and cell membrane
- Human and other animal cells have no cell wall
- Plant cells have cell wall
- Some bacteria have thick cell wall without outer membrane
- Other bacteria have thin cell wall with outer membrane
- Cell wall contains a layer of Peptidoglycan
- Thick peptidoglycan layer catches and keep crystal violet with iodine
- Outer membrane catches crystal violet with iodine but easily lose them by ethanol rinsing

Essential knowledge of malaria
- Epidemiology and disease burden of malaria worldwide
- Especially of Plasmodium falciparum
- Essential lifecycle
- Mosquito stage
- Human liver stage
- Human red cell stage
- Only P. vivax and P. ovale have hypnotic stage in liver cause relapse
- All species cause recrudescence due to inadequate/improper treatment
- Fever, Anemia, Splenomegaly
- Cerebral malaria almost only by P. falciparum, which leads to high mortality
- Diagnosis made by Rapid Diagnostic Test (RDT) and Blood smear microscopy (Giemsa staining)
- Blood smear includes thick smear (just to detect Plasmodium) and thin smear (confirm species of Plasmodium and degree of parasitemia as disease severity)
