Pneumonic plague is uncommon in dogs; most dogs with plague have bubonic or septicemic plague
and signs of fever, lethargy, and peripheral lymphadenopathy (7).
Pneumonic plague is one of three forms of plague (the others are septicemic plague
and bubonic plague) and is hypothesized to be responsible for the "Black Death" that depopulated Europe in the 1300's.
We generally assume that all individuals from each population are susceptible to the disease, the recovered individuals confer temporary immunity and return to be susceptible again, and the infectious are all individuals with either bubonic plague or pneumonic or septicemic plague
pestis was initially passed from person to person--say, when an infected individual coughed on a healthy person--and most likely caused lung infections known as pneumonic plague or blood infections called septicemic plague
, the researchers report in the Oct.
Bubonic is one of three commons types of plague along with pneumonic plague, an infection of the lungs, and septicemic plague
, an infection of the blood, according to (https://www.nlm.nih.gov/medlineplus/ency/article/000596.htm) United States National Library of Medicine .
, accounting for approximately 10% of cases, can occur from a flea bite or from direct contact with infectious fluids; infection spreads directly through the bloodstream with no localizing signs.
Bubonic plague can progress to septicemic plague
if bacteria move from the lymphatic into the circulatory system.
Three forms of plague are recognized in cats and people: bubonic plague, septicemic plague
and pneumonic plague.
More than half of the cases (eight) were bubonic plague, while the rest were primary septicemic plague
. Two patients developed secondary plague pneumonia.
, bubonic plague, and pneumonic plague were all part of the problem.
which lymphadenopathy is not apparent, may progress to septicemic plague
with dissemination by the blood to diverse parts of the body including the meninges.
