called Weeksella zoohelcum (CDC 11j)
Note for Pet Owners:

You should seek the advice of
your veterinarian if your pet is ill as only he or she can correctly advise
on the diagnosis and recommend the treatment that is most appropriate for
your pet.
Bergeyella
zoohelcum is a zoonosis. Zoonoses
are diseases that are transmissible between animals and humans. Some of
these diseases are extremely serious and potentially life-threatening
others cause only transient, mild disease. At the
time an animal appears ill there is no way of knowing whether or not it
is a zoonosis. For this reason it is important to follow basic hygiene
precautions such as washing hands after handling animals, not allowing
animals to soil eating implements or plates. If your animal is ill use
protective plastic gloves and clear up and dispose of any mess (eg urine
and faeces) as soon as possible .

Description
This organism is asscoaited with infected bite wounds from cats and dogs, and
also other infections in humans (including septicaemia and pneumonia) that
have been in contact with animals carrying the organism
Cause
Bergeyella zoohelcum (Weeksella
zoohelcum (CDC 11j)) is a nonfermentative, gram-negative, rod-shaped,
non-spore-forming, non-motile aerobic bacterium found in the oral cavity of
dogs or cats which may very occasionally cause infection in bite wounds. The
organism is found in 38-90% of oral and nasal fluids, and gingival scrapings
taken from dogs. It is also found as a commensal in human oral flora.
Breed Occurrence
Natural inhabitant of oral flora of dogs and cats
Signs
Cats and Dogs : None reported in dogs and cats. The
organism was isolated from the necrotic lung tissue of a cat with respiratory
disease, but it's significance is unknown. Humans : Reported
signs include those associated with wound infections, abscesses,
septicaemia, meningitis
Complications
Cats and Dogs : None reported in dogs and cats
Humans : Risk of septicaemia and localisation in
remote sites eg heart.
Diagnosis
The organism can be identified by PCR
amplification and sequencing techniques
Treatment
This organism has been reported to be sensitive to various antibiotics
including β-lactams, macrolides, tetracyclines, cefotaxime,
ciprofloxacin and gatifloxacin.
Prognosis
Humans : Good if treated
promptly
Long term problems
Risk of septicaemia and localisation in other sites, eg heart resulting in
endocarditis
