causes tooth decay, part of the "strep viridans group"
causes pneumonia, ear infections
causes more deaths than any other vaccine-preventable disease. They are preventable by a vaccine can cause pneumonia and childhood ear infections.(can be life treating) has a capsule if you make a strain without a capsule then it is unable to cause disease.
G.A.S= Group A Strep = can cause scarlet fever(upper respiratory and you get rash)
can lead to rheumatic fever. M protein is similar to a particular protein in cardiac muscle. Can also cause flesh eating diseases like necrotising fasciitis
diphtheria, exotoxin from infecting phage/ it was treated with horse serium
creates pseudomembrane, which can block trachea.
Gram -positive rod
causes meningioencephalitis (listeriosis)stillbirths and spontaneous abortions
they are spore formers and common in soilscutaneous- painless, usually if your around sheep, and common in soilsGastral Intestinal- get by eating contaminated meatPulmonary- w/o treatment it is 95% fatal. Difficult to diagnose and hard to treat, you get the disease because of the toxin the bacteria makes.
Gram Positive sporeformer
forms terminal endospores. causes botulism. These spores make toxin= Botulism neurotoxin3 forms1. wound
2. food poisoning
3. floppy baby syndrome( flaccid paralysis)
causes gas gangreneit is a strict anaerobe/most common in nursing homes.
Gram positive sporeformer
causes tetanus(spastic paralysis)
causes gonorrhea, neonatal blindness, and arthritis
non sexual contact. Happens to people who are in college dorms. people infected are at risk for gas gangrene.
normal intestinal microflora, necessary for the normal mouse gut vasculature
causes whooping cough, peaks at prodromal stage
normal enteric flora,severe diarrhea(from strain O157:H7)
is second invader after respiratory viruses causes pneumonia
gastroenteritis, common in catheter patients.
commonly causes nosocomial gastroenteritis and urinary tract infections.
grows in Swarming motility- regulated by quorum sensing. they sense that there is no nutrients in the spot they are inoculated and they grow flagella and move to a spot where there is food. and then they leave their flagella. causing a rippling effect.
Gram-negative rods/ Opportunisticyou get it most likely following medical implants , burns and cystic fibrosis
binduce their own phagocytosis by manipulating the human cytoskeleton from outside the human cell. 50% off chicken eggs have salmonella. Gets into GI tract causes diarrhea. It can also cause Typhoid fever-
FECAL COLIFORM = G-, lactose fermenting rods from GI tract.
Gram negative rods
red pigment, recent AB-resistant opportunistic pathogen
Gram-negative rodsbacillary dysentary
known as black plague. wild rodents carry it
bubonic-spread through fleas and rodents, which then infect humans. 50% fatal if untreated. cannot directly person to person. only by fleas. progresses to pneomonic plague.
Pneomonic plague- can spread person to person. it is 100% fatal. you get bacterial all over your body.
