Document Summary

Bacteria: single celled organisms, shaped as, rods, spheres, spirals, most are harmless and some are helpful, some are pathogenic and cause things like, cholera, syphilis, tuberculosis, used to be major cause of morbidity and death. Invasion: some bacteria can invade our cells. I. e. salmonella invades intestinal cells and cause severe diarrhea: tu(cid:271)e(cid:396)(cid:272)ulosis e(cid:374)te(cid:396)s (cid:271)ody i(cid:374) the lu(cid:374)gs a(cid:374)d (cid:862)hides(cid:863) i(cid:374)side (cid:272)ells so i(cid:373)(cid:373)u(cid:374)e syste(cid:373) (cid:272)a(cid:374)"t atta(cid:272)k. Gram staining of bacteria: technique used to classify bacteria as, gram positive, gram negative.

Gram positive vs gram negative: thin peptidoglycan layer (i. e. cell wall) in negative compared to thick layer in positive, negative also has outer membrane; positive does not. Signs of infection: fever, malaise, redness, swelling, neonates and seniors may not have a fever despite infection due to immature or.
