Microbiology: Some General Concepts

Appendages:
Think of appendages as limbs of bacteria.
Appendages must contain protein (Either just protein or Glycoprotein)

Bacteria Appendages:
Flagellum, Sex Pilus and FImbrae

Flagellum:
Think of Flagellum as the hind limbs or legs.
So Flagellum like leg is used for motility.
Since flagellum is used for one purpose = Motility, then it must contain only protein.
i.e One Purpose (Movement) = One Content (Protein)

Fimbrae (FB):
Helps bacteria to draw itself closer to a cell different from it
Helps bacteria attach to other cells it gets close to.
Fimbrae is Upper Fore limb. It uses its limbs to draw close to other cells and hold on to them.
FB makes a FB, ie Fimbra..........

Essay On Measles (Approx. 2000 Words) Supervised By Dr. Demba (MRC, The Gambia)

 Measles virus, a paramyxovirus is one of the main causes of death in children in developing countries and responsible for some deaths in industrialized nations. Infection resorts to immunosuppression, making the host more susceptible to secondary infections with a range of viral and bacterial pathogens and causing most measles associated (Carter et al, 2007).

Measles is an acute highly viral infectious disease. Before vaccines, infection was nearly universal during childhood. It has no known animal reservoir and no asymptomatic carrier state has been recorded (Roy P et al, 2015).

Measles is still a common and fatal disease especially in developing countries. It is primarily transmitted through large respiratory droplets. It is highly infectious, with greater than 90% secondary attack rates among susceptible persons (CDC, 2015). It infects nearly 30 million children per year worldwide. Complications related to pneumonia, diarrhea and malnutrition usually cause death (Orenstein et al, 2004).

WHO estimates that of the approximately two- thirds of the global burden of death due to measles, a
