Bacteria ID Flashcards
Largest group of pathogenic bacteria that is opportunistic
Coliforms
GNRODS
Can be spread by eating contaminated beef
E. Coli
Main reservoirs include: chickens, eggs, unpasturized milk, ground meat, and fish
Causes food poisoning or Typhoid F+
Salmonella
Found in soil, water, on plants, in humans and animals
Lg % of hospital infx by way of IV bags (Glucose/Dextrose)
Klebsiella
Subgenus of Salmonella
Largely seen in sheep
Arizona
Normal flora in human intestines
Swarms on BAP
Proteus
Common contaminant in dog and cat mouths and is isolated from dog and cat bites
Snuffles in rabbits
Pasturella
Poses an occupational risk to vet staff
W/in the repro tract of bovine, swine, goats, and humans
Eradicated from bovine from immunization of calves
Brucella
Poses an occupational risk to vet staff
Spread through contact with wild rabbits, rodents, or vectors
C/S: skin lesions and severe resp dz
Francisella tularensis
Causes cholera in humans
Comma shaped
Vibrio
Kennel cough in dogs
Bordetella
Dermatitis with blueish green purulent discharge
Primary pathogen of birds, reptiles, and amphibians
Fruity smell
Pseudomonas aeruginosa
Widespread in fresh water, sewage, and soil
Causes dz in fish, reptiles, and amphibians called Red Leg
Aeromonas
Species include: Bacillus,Listeria, Corynebacterium and Clostridium
GPRODS
Causes anthrax
one of the most pathogenic bacteria known to man
Produces an exotoxin that affects cardiovascular system
C/S: bleeding from all orifices, blood will not clot, no rigor mortis
Dx: blood draw from ear vein, DO NOT OPEN CARCASS
Bacillus anthracis
Contaminant of silage
20% mortality rate
One of the most deadly food borne pathogens
2 types: visceral and neural
Listeria monocytogenes
Causes caseous lymphadenitis, resp dz, and skin infx
Diptheria in humans
Pleomorphic
Corynebacterium
One of the most potent toxins to man
C/S: food poisoning and paralysis
One gram can kill one million people (Class A Bioweapon)
Inactivated by heat
Clostridium botulinium
Causes tetanus
Clostridium tetani
Causes GI infx and abortions
Thermophilic and microaerophilic
Campylobacter
Severe renal dz in dogs but rare in cats
Spread in urine
Leptospira
Need to acid fast stain to ID and survives phagocytosis
Tuberculosis in humans and cows
Mycobacterium
Need to acid fast stain to ID
Pleomorphic
No cell wall - resistant to penicillin
Pneumonia in humans and pigs
Mycoplasmas
Non-motile, GN bacteria that replicate within host cells
carried by parasites
Ex: Ehrlichia, Anaplasmatacae, Haemobartonella,
Rickettsial agents
