If any links are broken the transmission of an infecion can be stopped. Infecions agents or pathogens: types of microbes that can cause infecions (viruses, bacteria, fungi, protozoa, and helminths (parasiic worms). Virus: iny pathogens, 10-100 imes smaller than a bacteria and much smaller than fungi. Consists a bit of dna or rna (but never both) with a protein coat. Cannot reproduce on its own, must invade a living cell to reproduce. Bacteria: one-celled organism with dna so they are able to reproduce. Bacteria harm the body by releasing either enzymes that digest body cells or toxins that produce speciic efects of disease as diphtheria or toxic shock syndrome. Tb, tetanus, honoree, scarlet fever, and diphtheria are examples of bacterial disease. They can be killed by anibodies w/o harming out cells.
