28
ETEC in Pigs - Epidemiology
Disruption of equilibrium between maternal immunity and infection pressure Sow - MMA Piglet - Low birthweight
29
ETEC in Pigs - Pathogenesis

30
ETEC in Pigs - Diagnosis
Agglutination test | PCR
31
ETEC in Pigs - Treatment
Hydration | Antimicrobial
32
ETEC in Pigs - Prevention
Keep infection pressure low and maternal immunity high Proper Hygiene Vaccination Selection of receptor free piglets
33
VTEC in Pigs - Symptoms
EDEMA - Swollen eyelids, hoarse voice, CNS symptoms | Anorexia
34
VTEC in Pigs - Virulence
F 4,18 | St2e
35
VTEC in Pigs - Epidemiology
Sow to piglet | Weaning --> stress, changes in intestinal flora, maternal immunity
36
VTEC in Pigs - Pathogenesis
Excretion --> infection pressure increases --> contamination of other piglets
37
VTEC in Pigs - Toxin
Hyper acute - enterorrhagia Acute - permeability blood vessels edema Slower - intravascular coagulation Endotoxins - Shock and acute mortality
38
VTEC in Pigs - Diagnosis
Clinical signs Pathologic findings Bacteriology Virulence factors
39
VTEC in Pigs - Treatment
Reduce stress, Feed composition, Flora adaptation | Not yet affected - antimicrobial therapy
40
VTEC in Pigs - Prevention
Reduce stress Feed composition Adaptation of flora - probiotics, vaccination Receptor negative animals
41
EPEC in Pigs
Rare Diarrhea at weaning Diagnosis - Isolation + PCR
42
UTI in Pigs - Predisposing Factors
``` Hygiene Water intake Obstipation Age Individual ```
43
UTI in Pigs - Symptoms
Anorexia Hematuria Vaginal exudate General Malaise
44
UTI in Pigs - Diagnosis
Bacteriology
45
UTI in Pigs - Treatment
Culling | Antibiotics

51
ETEC in Bovine - Virulence
F 5,41,17 CS31A | STa,b
52
ETEC in Bovine - Pathogenesis
Orap uptake --> XXX intestine --> enterotoxin production --> secondary septicemia Immunity/infection pressure imbalance
53
ETEC in Bovine - Diagnosis
ELISA | Culture + Virulence factor
54
ETEC in Bovine - Therapy
Separate sick animals Provide hydration Antibiotics NSAIDs
55
ETEC in Bovine - Prevention
Hygiene - separate calves from mothers | Antibiotics
56

59
Septicemia in Bovine - Virulence
Serum resistance Iron uptake systems Capsule F17, CS31A, CNF1 and CNF2
60
Septicemia in Bovine - Pathogenesis
Bacteria PO --> lymph tissue of head, throat, intestine | Umbilical cord --> septicemia colostrum
61

73
E. Coli in Poultry - Clinical Signs
Neonatal - Colibacillosis Respiratory - colibacillosis and septicemia Peritonitis
74
E. Coli in Poultry - Pathogenesis Neonatal
Yolk rest infection --> sepsis --> death Yolk rest infection --> Polyserosistis/airsac/pericardia --> growth retardation Contamination of egg shell Neonatal contamination Manipulation of chicks
75
E. Coli in Poultry - Pathogenesis Respiratory Colibacillosis
