What
is glanders?
Glanders
is an infectious disease that is caused by the bacterium
Burkholderia mallei. Glanders is primarily a disease
affecting horses, but it also affects donkeys and mules and
can be naturally contracted by goats, dogs, and cats. Human
infection, although not seen in the United States since 1945,
has occurred rarely and sporadically among laboratory workers
and those in direct and prolonged contact with infected,
domestic animals.
Why has
glanders become a current issue?
Burkholderia mallei
is an organism that is associated with infections in
laboratory workers because so very few organisms are required
to cause disease. The organism has been considered as a
potential agent for biological warfare and of biological
terrorism.
How common is
glanders?
The
United States has not seen any naturally occurring cases since
the 1940s. However, it is still commonly seen among domestic
animals in Africa, Asia, the Middle East, and Central and
South America.
How
is glanders transmitted and who can get it?
Glanders is
transmitted to humans by direct contact with infected animals.
The bacteria enter the body through the skin and through
mucosal surfaces of the eyes and nose. The sporadic cases have
been documented in veterinarians, horse caretakers, and
laboratorians.
What are the
symptoms of glanders?
The
symptoms of glanders depend upon the route of infection with
the organism. The types of infection include localized,
pus-forming cutaneous infections, pulmonary infections,
bloodstream infections, and chronic suppurative infections of
the skin. Generalized symptoms of glanders include fever,
muscle aches, chest pain, muscle tightness, and headache.
Additional symptoms have included excessive tearing of the
eyes, light sensitivity, and diarrhea.
-
Localized infections
– If there is a cut or scratch in the skin, a localized
infection with ulceration will develop within 1 to 5 days at
the site where the bacteria entered the body. Swollen lymph
nodes may also be apparent. Infections involving the mucous
membranes in the eyes, nose, and respiratory tract will
cause increased mucus production from the affected sites.
-
Pulmonary infections
- In
pulmonary infections, pneumonia, pulmonary abscesses, and
pleural effusion can occur. Chest X-rays will show localized
infection in the lobes of the lungs.
-
Bloodstream infections
- Glanders bloodstream infections are usually fatal within 7
to 10 days.
-
Chronic infections
- The chronic form of glanders involves multiple abscesses
within the muscles of the arms and legs or in the spleen or
liver.
Where is glanders
usually found?
Geographically, the disease is endemic in Africa, Asia, the
Middle East, and Central and South America.
How is glanders diagnosed?
The
disease is diagnosed in the laboratory by isolating
Burkholderia mallei from blood, sputum, urine, or skin
lesions. Serologic assays are not available.
Can
glanders spread from person to person?
In
addition to animal exposure, cases of human-to-human
transmission have been reported. These cases included two
suggested cases of sexual transmission and several cases in
family members who cared for the patients.
Is there a way
to prevent infection?
There is
no vaccine available for glanders. In countries where glanders
is endemic in animals, prevention of the disease in humans
involves identification and elimination of the infection in
the animal population. Within the health care setting,
transmission can be prevented by using common blood and body
fluid precautions.
Is there a
treatment for glanders?
Because
human cases of glanders are rare, there is limited information
about antibiotic treatment of the organism in humans.
Sulfadiazine has been found to be effective in experimental
animals and in humans.
