Bacilli rod shaped eg. salmonella; flagella (circles. Gram positive- purple (this means taking up the stain crystal violet easily) Gram negative pink (does not take up the stain crystal violet) Anaerobic bacteria do not require oxygen eg. clostridia spp. Once you seal out the oxygen in a can for example you have a low oxygen environment causing the growth of clostridia. Facultative anaerobic bacteria can grow in presence or absence of oxygen examples include: salmonella species, e. coli, s. aureus. Thermophile- can grow at high temperatures (out of the danger zone) Halophile can tolerate high concentrations of salt e. g vibrio cholera (cholera out(cid:271)(cid:396)eak (cid:272)o(cid:374)(cid:272)e(cid:396)(cid:374) (cid:449)he(cid:374) the(cid:396)e"s ea(cid:396)th(cid:395)uakes o(cid:396) distu(cid:396)(cid:271)a(cid:374)(cid:272)es to the (cid:449)ate(cid:396) system) Onset symptoms: 2-5 days (consumption to when you become ill) Symptoms include abdominal pain and bloody diarrhea; (self limiting illness meaning that if you are a healthy adult you should only be ill for a few days before your body creates a defense against the disease)
