Leptospirosis
 Dogs
become infected by leptospires when abraded skin comes into contact with the
urine of an infected host. The organisms quickly spread through the bloodstream
leading to fever, joint pain, and general malaise which can last up to a week.
The organism settles in the kidneys and begins to reproduce, leading to further
inflammation and then kidney failure.
Milder signs are often
seen with the kidneys being the main organs effected. Jaundice is seen less often and is
less severe. However damage to the kidneys may cause problems later in life.
Dogs that recover can excrete the bacteria in the urine for up to a year.
Two forms of disease are seen.
Leptospira icterohaemorrhagiae (Weil's disease), Incubation period, 5-15 days.
Transmission, by rats or dogs which kill
rats. Dogs may be infected by rat urine on the ground, in ponds or water bowls.
Major signs,
High temperature, severe thirst, increased frequency of urination,
abdominal pain, depression, diarrhea containing blood, jaundice, vomiting.
Leptospire canicola
(Lamppost disease and Stuttgart disease), Incubation period,5-15 days.
Transmission, Dog to dog via sniffing at urine (hence lamppost connection).
Major signs, Similar to those described under
Leptospire icterohaemorrhagiae except that jaundice is much less seen.
