Study Notes

Bovine Viral Enteritis

Rinderpest

Highly contagious viral disease of cattle
Family: Paramyxoviridae, Genus: morbillivirus (RNA)
High fever, anorexia, decreased milk yield
Nasal/ocular mucopurulent discharge, severe bloody diarrhea, dehydration, shock, death
Gross findings: Focal erosions and ulcers of the upper GI, hemorrhagic, necrotic, edematous Peyer’s patches, hemorrhage and congestion of cecum, colon, rectum (zebra stripes)
Microscopic findings: Lymphoid necrosis, necrosis of intestinal crypts, syncytia, intracytoplasmic & intranuclear inclusion bodies

Bovine Viral Diarrhea (BVD)

Acute, highly contagious, worldwide disease of cattle
Family: Flaviviridae, Genus: Pestivirus
High morbidity and mortality, fever, diarrhea, pneumonia
Gross findings: Erosions and ulcerations of the GI, linear esophageal ulcerations, Peyer's patches swollen, necrohemorrhagic
Infection at various stages of gestation can lead to fetal death, abortion, mummification, congenital defects (cerebellar hypoplasia), or persistent infection

Rotavirus and Coronavirus

Common causes of calf diarrhea
Attack the villi of the small intestine
Rotavirus (1-2 weeks old), Coronavirus (calves < 3 weeks old)
Often associated with each other and other diarrhea pathogens

Canine parvovirus enteritis (CPV-2)
Canine distemper

Canine Parvovirus Enteritis

Interstitial myocarditis in puppies (rare)

Canine Distemper

Colibacillosis
Salmonellosis
Enterotoxemia (Clostridium perfringens)

Colibacillosis

Gram-negative bacteria
Non-virulant strains are considered normal flora
Most common cause of neonatal diarrhea in calves and pigs
Enterotoxigenic E.coli (ETEC): Ingestion of virulent bacteria > adherence to small intestinal enterocytes > toxin production > diarrhea

Salmonellosis

Important zoonosis worldwide
Fecal-oral route of transmission
Disease Forms: Septicemic, Acute Enteric, Chronic Enteric
Most animals are symptomless carriers
Stressors and diseases that compromise immune competence or disrupt the enteric bacterial ecosystem are often implicated

Enterotoxemia

Caused by Clostridium perfringens
Characterized by sudden death in well-nourished animals, necrotizing/hemorrhagic enterocolitis and toxemia
Gram positive, sporulating, anaerobic bacillus
Five strains (A-E) based on production of exotoxins (alpha, beta, epsilon, and iota)
Epsilon toxin (ETX) is the third most potent clostridial toxin
