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
