Which obligate anaerobe produces cytotoxin?
Which obligate anaerobe produces an enterotoxin-like entity?
True/False. The immune response plays a major role in resolving the pyonecrotic process involving obligative anaerobes.
The immune response plays a MINOR role in resolving the pyonecrotic process involving obligative anaerobes.
True/False. Non-spore forming anaerobes are part of the normal flora.
Which toxin produced by this group of bacteria is inhibitory to polymorphnucleotides?
What is a key aspect to the samples taken for diagnosis of anaerobes?
The samples have a very repugnant odor (same for invasive clostridia)
Due to volatile fatty acid production
What increases the chance of bacterial infection with this group?
Very low blood supply and low O2 supply
Describe the "glove box" that is used to isolate this group of bacteria.
IMPORTANT FOR ISOLATION: reduce O2 in environment
"glove box" - anaerobic chamber where you place your hands in gloves to be able to manipulate the samples within the chamber
How does the general pathogensis for these obligate anaerboes work with faculative bacteria?
Continous synergistic inflammatory response between anaerobes and falcultative anaerobic bacteria
(capsule, cell wall, toxins, phagocytes)
What are the common facultative organisms that are synergistic with anaerobes during infection?
Pasteurella and enterics in dogs/cats
Beta-hemolytic streptococci and enterics in horses
Arcanobacterium pyogenes and enterics in ruminants
**would treat for both anaerobes and facultative organisms**
Dichelobacter is gram _____.
Fusobacterium necrophorum is gram ______.
Which anaerobe is a causative agent of bovine liver abcesses?
Which anaerobes are the caustive agents of foot rot? Which species is susceptible?
Dichelobacter nodsus and Fusobacterium nercrophorum
Contagious infectious dz affecting epidermal portions of food of sheep and goats - causes cripling lameness
Whic anaerobe causes calf diphteria?
**calf diphteria - necrotic pharyngitis or laryngitis
Which anaerobe causes necrotic rhinitis of pigs?
Which part of the body would you swab to isolate F. necrophorum?
The oral cavity and gastrointestinal tract of animals
Which anaerobe produces leukotoxin and hemagluttinin that facilitates the survival of synergistic bacteria?
Synergistic bacteria: D. nodsus and A. pyogenes
How would you treat foot rot?
Removal and exposure of diseased tissue - hoof triming with disinfectants or antibiotics (penicillen and streptomycin)
