Common Bacterial Diseases in Dogs
The bacteria can be cultured from nasal swabs or transtracheal washings.
Treatment: Treat all upper respiratory infections by placing the animal in a
warm, draft-free environment, humidifying the atmosphere, and avoiding
stressful activities that can interfere with a smooth recovery. Antibiotics are
indicated if the dog develops fever and a mucopurulent nasal discharge. Antibiotics
are also indicated for all cases of upper respiratory infection in which
bordetella is isolated. Antibiotics given by nebulizer may be more effective
than those given orally or by injection. This is because the bacteria attach to
the mucosal surface of the respiratory tract and are difficult to reach with
Prevention: Bordetella vaccinations are not routine, but may be advisable for
show dogs, boarded dogs, dogs who go to grooming salons or obedience classes, and dogs who live
Campylobacteriosis is a disease that produces acute infectious diarrhea in
puppies. It also occurs in kennel dogs and strays-most of whom are in poor
condition and are suffering from other intestinal infections.
The bacteria is acquired by contact with contaminated food, water, uncooked
poultry or beef, and animal feces. Campylobacteria can survive for up to five
weeks in water or unpasteurized milk.
The incubation period is one to seven days. Signs of acute infection include
vomiting and a watery diarrhea that contains mucus and sometimes blood. The
disease usually runs its course in five to fifteen days, but may be followed by
chronic diarrhea in which bacteria is shed in the feces.
Treatment: Treat mild diarrhea. Keep the dog warm, dry, and in a stress-free
environment. More severely affected dogs will require veterinary management
with intravenous fluids to correct dehydration. Antibiotics may be advisable.
Erythromycin and ciprofloxin are the drugs of choice.
Public health considerations:Campylobacteriosis is a common cause of
diarrhea in humans. Most human cases arise from contact with newly acquired
kittens and puppies who are suffering from diarrhea. Parents should be aware
that puppies with diarrhea may harbor a human pathogen. Good hygiene is
essential, especially for young children and people who are
