| |
| − | *Commensal of the equine intestinal and reproductive tract
| |
| − | *Pathogenesis and clinical signs:
| |
| − | **Foals infected ''in utero'' or or after birth via the umbilicus
| |
| − | **Infection at birth causes severe enteritis and septicaemia within 24 hours, known as sleepy foal disease
| |
| − | **Foals become pyrexic and recumbent
| |
| − | **Death usually occurs within 1-2 days
| |
| − | **In foals that survive neonatal infection the condition progresses to cause joint infections and purulent nephritis, enteritis or pneumonia
| |
| − | **''A. equuli'' in [[Joints Inflammatory - Pathology#In Horses|arthritis of horses]]
| |
| − | **Abortion, septicaemia and [[Peritoneal Cavity Inflammatory - Pathology#In horses|peritonitis in horses]]
| |
| − | *Diagnosis:
| |
| − | **Specimens cultured on blood agar and MacConkey agar and incubated aerobically for 1-3 days
| |
| − | **Sticky colonies with variable haemolysis on blood agar
| |
| − | **Lactose-fermenting colonies on MacConkey agar
| |
| − | *Treatment and control:
| |
| − | **Antimicrobials ineffective unless early in course of disease
| |
| − | **Blood trasfusion and administration of colostrum
| |
| − | **Good hygiene
| |
| − | **Consider prophylactic antibiotics for new-born foals
| |
| − | **Bacteria susceptible to streptomycin, tetracyclines and ampicillin
| |
| − | *In other animals:
| |
| − | **Septicaemia in piglets
| |
| − | **Arthritis and enteritis in pigs
| |
| − | **Enteritis in calves
| |
| − | **RTX group cytotoxin present
