Certain zoonotic bacterial diseases A20-A28 >
infection due to Yersinia pestis
A gram-negative bacterial infection caused by yersinia pestis.
It is usually transmitted to humans from bites of infected
rodent fleas. It is manifested as a bubonic, septicemic, or
pneumonic plague. In bubonic plague, the lymph nodes adjacent
to the site of the skin bite are infected and enlarged. In
septicemic plague, the infection spreads directly through the
bloodstream. In pneumonic plague, the infection spreads to the
lungs either following bubonic plague, or by inhalation of
infective droplets. If untreated, it may lead to death.
Acute infectious disease caused by yersinia pestis that affects
humans, wild rodents, and their ectoparasites; bubonic plague
is the most common form.
An acute infectious disease caused by yersinia pestis that
affects humans, wild rodents, and their ectoparasites. This
condition persists due to its firm entrenchment in sylvatic
rodent-flea ecosystems throughout the world. Bubonic plague
is the most common form.
An infectious disease
Plague is an infection caused by the bacterium yersinia pestis.
The bacteria are found mainly in rats and in the fleas that
feed on them. People and other animals can get plague from rat
or flea bites. Historically, plague destroyed entire civilizations.
In the 1300s, the "black death," as it was called, killed approximately
one-third of europe's population. Today plague is uncommon. This is
largely due to better living conditions and antibiotics. There are
three forms of plague:
bubonic, which causes the tonsils, adenoids, spleen and thymus to
become inflamed. Symptoms include fever, aches, chills and tender
septicemic, in which bacteria multiply in the blood. It causes fever,
chills, shock and bleeding under the skin or other organs
pneumonic, in which the bacteria enter the lungs and cause pneumonia.
People with the infection can spread this form to others. This type
could be a bioterror agent
treatment for plague is a strong antibiotic.
There is no vaccine for plague.
Tularemia A21- >
infection due to Francisella tularensis
A plague-like disease of rodents, transmissible to man. It is
caused by francisella tularensis and is characterized by fever,
chills, headache, backache, and weakness.
A serious gram-negative bacterial infection caused by francisella
tularensis. It is transmitted to humans through bites from infected
insects, inhaling airborne bacteria, handling infected animals, or
consuming contaminated food or water. Signs and symptoms include
skin ulcers, mouth sores, lymphadenopathy, sore throat, fever and
Disease caused by francisella tularensis and transmitted to man
from rodents through the bite of a deer fly, chrysops discalis,
and other bloodsucking insects; symptoms consist of a prolonged
fever and often swelling of the lymph nodes; rabbits are important
Anthrax A22- >
infection due to Bacillus anthracis
An acute infection caused by the spore-forming bacteria bacillus
anthracis. It commonly affects hoofed animals such as sheep and
goats. Infection in humans often involves the skin (cutaneous
anthrax), the lungs (inhalation anthrax), or the gastrointestinal
tract. Anthrax is not contagious and can be treated with antibiotics.
An infection caused by bacillus anthracis bacteria. It may affect
the lungs, gastrointestinal tract, or skin. Patients with lung
infection present with fever, headaches, cough, chest pain and
shortness of breath. Patients with gastrointestinal infection
present with nausea, vomiting and bloody diarrhea. Patients with
skin infection develop blisters and ulcers.
Anthrax is a disease caused by bacillus anthracis, a microbe that
lives in soil. Many people know about it from the 2001 bioterror
attacks. In the attacks, someone purposely spread anthrax through
the United States Mail. This killed five people and made 22 sick.
Anthrax affects farm animals more often than people. But it can
cause three forms of disease in people. They are:
cutaneous, which affects the skin. People with cuts or open sores
can get it if they touch the bacteria.
inhalation, which affects the lungs. You can get this if you
breathe in spores of the bacteria.
gastrointestinal, which affects the digestive system. You can
get it by eating infected meat.
antibiotics often cure anthrax if it is diagnosed early. But
many people don't know they have anthrax until it is too late
to treat. A vaccine to prevent anthrax is available for people
in the military and others at high risk.
Infectious bacterial zoonotic disease usually acquired by
ingestion of bacillus anthracis; marked by hemorrhage and
serous effusions in the organs and cavities and symptoms of
Brucellosis A23- >
A gram negative bacterial infection caused by bacteria of the
genus brucella. Humans are infected by ingesting unpasteurized
milk or meat from infected animals. Signs and symptoms include
fevers, sweating, weakness, headache, muscle pain, arthritis
Infection caused by bacteria of the genus brucella mainly
involving the mononuclear phagocyte system. This condition
is characterized by fever, weakness, malaise, and weight loss.
Rat-bite fevers A25- >
A syndrome characterized by recurring fever, rash, and
arthralgias occurring days to weeks after a rat bite. The
causative agents are either streptobacillus moniliformis
or spirillum minus.
Erysipeloid A26- >
An infection caused by erysipelothrix rhusiopathiae that
is almost wholly restricted to persons who in their occupation
handle infected fish, shellfish, poultry, or meat. Three forms
of this condition exist: a mild localized form manifested by
local swelling and redness of the skin; a diffuse form that
might present with fever; and a rare systemic form associated
Leptospirosis A27- >
A contagious bacterial infection caused by spirochetes of the
genus leptospira. Humans are infected by contact with water and
soil which have been contaminated with animal waste products.
The signs and symptoms include an initial flu-like phase, followed
by a second phase in which patients may develop meningitis, liver
failure and renal failure.
Infections with bacteria of the genus leptospira.
