Clinical Characteristics and Pathology

Detailed Clinical and Pathological Characteristics

General

WATERFOWL Acute disease with generalized, multi-systemic signs and general but sometime minimal septicaemic lesions.

Clinical Characteristics

WATERFOWL
  • Peracute or acute general disease.
  • Depression, anorexia, enteritis (sometimes haemorrhagic), weight loss and death.

(B11.40.w8, B13.46.w1).

Incubation

WATERFOWL Peracute or acute infection (B11.40.w8).

Mortality / Morbidity

WATERFOWL --

Pathology

WATERFOWL
  • Gross lesions may be seen in chronic disease, but are usually absent in peracute disease.
  • Liver - congestion, necrotic foci
  • Spleen - enlarged
  • Respiratory - lungs congested and petechiated
  • Gastro-intestinal tract - congestion and petechiation on serosal surfaces. May be enteritis, sometimes haemorrhagic. Necrotic colitis may be seen with Salmonella infections.

Similar Diseases (Differential Diagnosis)

WATERFOWL Identification of the organism involved is recommended. Various bacteria including Erysipelothrix rhusiopathiae, Escherichia coli, Pseudomonas spp. Salmonella spp., Streptococcus spp. and others may be responsible for neonatal septicaemia. Systemic infections may also be linked to Localized infections such as yolk sacculitis (Omphalitis / Yolk Sacculitis) (B11.40.w8, B13.46.w1).
