E. coli bovines canines felines Flashcards
What are the E. coli diseases in Bovines
ETEC
EPEC and EHEC
septicemia
Calfs
ETEC
Calfs older than one week E. coli?
EPEC & EHEC
Neonate calfs that didn’t get their mothers colostrum?
Septicemia
Virulence Factors of ETEC Bovine
Fimbrial F5 (most common) F41 (freq w/ F5) F17- role unclear CS31A- role unclear- DIARRHEA OLDER ANIMALS
Toxins
Sub type A & B
Pathogenesis ETEC Bovine
Oral uptake
Multiplication
Enterotoxin Production
(Secondary septicemia)
What causes ETEC in cows?
Colostrum- too little too late too few in antibodies
Dx of ETEC in Bovines
Elisa
Culture + Virulence factors (agglutination or PCR)
Tx of ETEC in bovines?
Separate ill animals
Hydration
Antibiotics
NSAIDS
Bovine ETEC milking farm Tx
Hygiene- separate calfs from cows.
Colostrum- of multi parts animals
EHEC and EPEC bovine Genes Age of illness signs zoonotic? therapy?
EPEC- eae EHEC-eae + VT 1-8wks muccoid diarrhea +/- Blood large intestine Zoonotic (O157:H7) Antibiotics
Only one slide of info on Dz
Mastitis bovines E. coli details?
No virulence factors known
DDx: Gram+/Gram-
Gram- w/ fever
Freq lost udder quarter
Prevention: hygine
Tx: systemic Antibiotics
E. coli septicemia virulence factors for bovines
Serum resistance Iron uptake systems endotoxin capsule Adhesion factors (P, F17, Afae-VIII, CS31A) CNF1, CNF2toxins
Septicemia bovines hyperaccute?
Acute mortality
Shock
Acute septicemia bovines
General symptoms
Fast mortality
Slower Septicemia with organ localization?
Poly arthritis, pneumonia, pleuritis, menigo-encephalitis
Dx: Septicemia Bovines
Clinically (age, signs, colostrum: low gamma globulins in serum)
Isolation + PCR for virulence genes
Tx: Septicemia Bovine
NSAID (Shock)
antibiotics
Gamma globulins (plasma from older animals
Prevention of septicemia in cows
Colostrum
E. coli in Dogs
ETEC, EPEC, VTEC, EIEC: both in clinically healthy as well as diarrheic K9s
Freq found w/ other pathogens (Parvo, C. perfringens, parasites)
E. coli puppies
CNF1 E. coli- diarrhea and septicemia
Cystitis Canine E. coli
Fimbria
Serotypes
Hemolytic pattern?
Type 1, F12, F13
O2, O4, O6, O83
50% alpha-hemolytic
Cystitis in cats due to E. coli
not common cats have high urine osmolarity
Pyometra K9 E. coli
Same strains as cystitis
Whats the most important BacT disease in Broilers and Layers?
E. coli
Facultative pathogen
E. coli serotypes in poultry and birds?
O1, O2, O78
Clinical appearance of E. coli in Avian species
Neonatal- Colibacillosis
Respiratory- Clibacillosis & septicemia
Pertonitis- Layers
Dx: E. coli avian
Pathological lesions
Isolation from different internal organs (Liver, spleen, lung)
DDx: E. coli avian
Yolk rest infection (omphalitis)
Salmonella, staph, proteus, clostridia, pseudomonos, enterococcus
Acute sepsis
Pasteurella, salmonella, strep, erysipelothrix
Coligranuloma
TB, tumor, chronic blackhead syndrom (turkey)
Airsaculitis
CRD, NDV, IB, ORT, aspergillosis
Tx: E. coli birds
Very difficult
Antibiotics
Prevention
Hygiene
stress
tempurature
Vaccine (Poulvac) for breeding stock
Scabby hip/ necrotic dermatitis in broilers?
E. coli O78, O2
Difficult to diagnose (Feathers)
Found at slaughter
prevent by lowering animal density
RPEC
Rabbit pathogenic E. coli
Dx of RPEC
clinical symptoms
Isolation and subtyping (necessary)
Tx of RPEC
antibiotics
