107dog.wordpress.com

 BASICS
OVERVIEW

• Sudden or recent onset of abnormally increased water content and/or solid content in the bowel movements

SIGNALMENT/DESCRIPTION of ANIMAL

•  Dogs or cats
• Any animal can suffer from acute diarrhea; kittens and puppies are affected most frequently

SIGNS/OBSERVED CHANGES in the ANIMAL

• Acute diarrhea is usually self-limiting (will resolve quickly), an isolated episode and does not affect the animal in general
• Other cases are mild, do not affect the animal in general, and resolve after a few days
• Sometimes it is sudden (acute) or very sudden (peracute) severe disease; more common in dogs (for example, parvovirus-related diarrhea) than cats 

Chronic Gastritis

BASICS
OVERVIEW

• Intermittent vomiting of more than 1 to 2 weeks’ duration, secondary to inflammation of the stomach (known as “gastritis”)
• Presence of shallow ulcers (known as “ erosions”) or ulcers in the stomach, dependent on the cause and duration of the stomach inflammation

SIGNALMENT/DESCRIPTION of ANIMAL
Species

Feline Infectious Peritonitis (FIP)

BASICS
OVERVIEW

• A generalized (systemic), viral disease characterized by subtle onset of signs, persistent fever that does not respond to treatment, Inflammatory nodular tissue reaction with the presence of pus (known as “pyogranulomatous tissue reaction”), accumulation of inflammatory fluids in body cavities, and high mortality

SIGNALMENT/DESCRIPTION of ANIMAL
Species

• Cats—domestic and exotic Breed Predilections
• Some families or lines of cats appear more susceptible to feline infectious peritonitis (FIP) Mean Age and Range
• Highest incidence of disease—in kittens 3 months to 3 years of age
• Incidence of disease decreases sharply after cats reach 3 years of age

Canine Parvovirus Infection

 BASICS
OVERVIEW

• Canine parvovirus (CPV) infection is characterized clinically by lack of appetite, vomiting, diarrhea, and weight loss; severe disease may result in generalized bacterial infection (known as “ sepsis”), presence of bacterial toxins in the blood (known as “ endotoxemia”), blood clotting disorder (known as “disseminated intravascular coagulopathy” or “DIC”), and acute respiratory distress syndrome (ARDS)
• The original canine parvovirus underwent genetic alterations, developing into CPV-1 and CPV-2; CPV-2 developed further into CPV-2a in 1980 and CPV-2b in 1984
• Most severe disease is associated with CPV-2b
• CPV-1 may cause unmanageable, usually fatal diarrhea in newborn puppies
• Recently CPV-2b has shown mutation into a variant form designated Glu426
