what are the types of vagal indigestion of cows
- type 1: can’t burp- esophageal obstruction,cervical mass, free gas bloat:tetanus, frothy bloats
- type 2: foailure of omasal transport: hardware disease, liver abscess, cancer
- type 3: pyloric outflow obstuction- abomasal ulcer/adhesion, displacement, sand impaction
abomasal tosion
Creat (fluid to serum creat 2:1)

actinomycosis
A. bovis- bacteria- branching gram + rod
skin scrape
silicate
advanced traumatic reticulopericarditis
- hardware disease
- breaks through the reticulum and stabs through diaphragm and maybe into heart
- arches back- reluctance to dip when withers pinched, cranial abdominal pain, bottle jaw, brisket edema
- plasma fibrinogen >1000
- nrutrophilia, left shift
- if chronic: globulin rises and albumin falls

intussusception
gestation period for cow
283
(9 months)
free gas bloat, failure to eructate
type 2 vagal indigestion
- failure of omasal transport: fluids do not leave reticulo-rumen
- mild acid-base electrolyte abnormalities (type 3 has severe)
- papple
type 3 vagal indigestion
- pyloric outflow not working
- can be very large (papple?)
- internal vomiting: abdomasal contents move into rumen. Increases the rumen Cl= lowCl in blood causing alkalosis
- Cl in abomasum is usually reabsorbed in the duodenum. In type 3, Cl instead moves into the rumen
- H ions from the abomasum are usually buffered in duodenum by pancreatic and duodenal bicarb
- because the cow has low Cl, the anion is replaced by making bicarb by renal mechanisms to maintain neutrality= becomes alkalotic
- paradoxic aciduria: cow is hypovolemic, kidneys try to save Na to keep water, that means Na is traded for H= acid urine
- Treatment: IV fluids high in Cl (KCl 50-100 gram per L of NaCl), usually 2ndary to peritonitis, can cause Afib (usually does not need to be treated- will resolve)
why will type 3 vagal indigestion cause paradoxic aciduria
type 3: pyloric outflow blocked= Cl into rumen= becomes alkolytic
* will become hypovolemic, low Cl, lowK as water is pulled into rumen.
* kidneys will try to maintain blood pressure by keeping Na, they will exchange H, making acidic urine

common bacteria that can cause respiratory disease in cows
what are 4 common viral diseases that cause respiratory disease in cows
- infectious bovine rhinotracheitis (IBR)- bovine herpesvirus 1
- parainfluenza 3 (PI-3)
- Bovine respiratory syncytial virus
- bovine viral diarrhea virus
shipping fever is caused by
Mannheimia haemolytica (gram - bacteria)
M. hemolytica produces —
shipping fever in cow
* gram negative bacteria that makes leukotoxin and endotoxin
vaccine should include leukotoxin
can work with BVDV to cause immunosupression and brochopneumonia
histophilus somni causes
TEME (Bovine thrombotic meningoencephalitis )
* respiratory, neuro disease, polyarthritis
will have yellow (xanthochromia) CSF
CSF from a sick neuro/respiratory cow with yellow CSF could be
Histophilus somni

enzootic pneumonia
bronchopneumonia- chronic abscesses in lungs
gram negative coccobacillus
mycoplasma bovis is what type of bacteria
- has no cell wall- need to pick antibiotics carefully
- gram negative ish- pleomorphic
- Facultative anaerobe
- cause respiratory and musculoskeletal infections in cattle, including pneumonia, mastitis, and arthritis.
- bovine respiratory disease complex (BRD) and can cause chronic infections
can cause bronchopenumonia, polyarthritis, and ear infection in cows

malignant catarrhal fever (MCF)
clinical signs of malignant catarrhal fever
Clinical signs: cloudy eyes/corneal opacity, mucous nasal discharge, thichened cracked skin, diarrhea, high fever, depressed, enlarged lymphnodes, RBC in urine, oral erosion
diagnosis: elisa for serum antibodies, PCR on blood or tissue, can have false neg with asymptomatic carriers
Pathology: T lymphocytic vasculitis that causes obliterative arteries
Prevention: keep sheep away from cattle and bison and keep wildebeest away, no vaccines avilable
- Caused by gamma herpes virus: Alcelaphine herpesvirus type 1 (A1HV-1 (wildebeest reservoir)
- Ovine herpesvirus type 2- sheep assos MCF virus (sheep reservoir)
- Caprine herpesvirs type 2 (reservoir goats)
- MCFV of white tailed deer (reservoir unknown)
- only survives hours in environment
- shed in nasal secretions and other fluids by carriers (sheep and wildebeest)
- cattle usually dead end hosts
- 50% of cattle can be asymptomatic
- vertical transmission in utero and via milk in cattle and bison
