STAPHLOCOCCOSIS

exp date isn't null, but text field is

Causative Agent(s)

Staphylococcus aureus, a facultatively anaerobic, beta-haemolytic, and catalase and coagulase positive Gram-positive cocci.

Clinical Presentation and Epidemiology

Wounds are major points of entry into the bird’s body. Infection in any organ/tissue can cause septicaemia. There is tendency to spread to bones and joints such that the most common clinical presentation is lameness. Usually, the pathology affect the proximal tibiotarsus and proximal femur. S. aureus can also cause navel and yolk sac infections. S. aureus can also cause food poisoning.

Diagnostic Consideration

Examination of the synovial fluid aid diagnosis and is usually found to be white in colour. Cultural isolation from joint fluids, wounds, and other lesions, by selective plating and further microbiological examination can provide isolates for susceptibility testing of antibiotics

Management and Treatment

Staphylococcosis can be successfully treated with antibiotics, but an antimicrobial susceptibility test should be performed. Antibiotics used to treat Staphylococcus infections include penicillin, erythromycin, lincomycin and spectinomycin. Sanitation is important in control.
