Summary Information
Morphology, Staining and Metabolism information at genera level (Staphylococcus)

(Classification of bacterial species is an evolving discipline. The information in Wildpro has been carefully referenced to the source material, as far as possible. Readers requiring further clarification should consult the source materials and more recent publications. Classification information in Wildpro will be altered when clear and scientifically endorsed new information regarding taxonomic divisions becomes available to us.

This section is currently predominantly used in Wildpro to link different data types and demonstrate inter-relationships. It does not contain detailed information on the bacteria species itself.)

Common synonyms --
Notes Staphylococcus aureus frequently colonizes the skin, nose and oropharynx of healthy animals. (B47) (B75) It occurs worldwide (B21)

Associated Diseases linked in Wildpro
"Staphylococcus aureus is a potential pathogen causing a wide range of infections; major infections include furuncles (boils) carbuncles, impetigo, toxic epidermal necrolysis, pneumonia, osteomyelitis, meningitis, endocarditis, mastitis, bacteraemia, various abscesses, food poisoning (via enterotoxin), enterocolitis, urogenital infections and toxic shock syndrome." (B75) (B88) (B21)
Associated Waterfowl Diseases Bumblefoot (Pododermatitis, Chronic arthritis-synovitis) Waterfowl Disease Summary Inflammation and bacterial infection of the connective tissues of the foot, linked to abrasive surfaces.
Waterfowl in which the disease has been recorded.
Omphalitis / Yolk Sacculitis (Infected yolk sac, Yolk infection, Omphophlebitis, Yolk sacculitis) Waterfowl Disease Summary Bacterial infection of the yolk sac and/or umbilical area. May lead to, and is predisposed by, yolk sac retention.
Waterfowl in which the disease has been recorded.
Staphylococcosis (Staphylococcus Infection, Infective Arthritis, Staphylococcal septicaemia, Staphylococcal blood poisoning) Waterfowl Disease Summary Bacterial infection which may be seen as a localized skin infection (e.g. Bumblefoot), arthritis, or as a generalized, septicaemic infection.
Waterfowl in which the disease has been recorded.
Salpingitis (Oviduct Infection, Oviduct Inflammation) Waterfowl Disease Summary Inflammation of the oviduct, usually associated with infection, sometimes with associated peritonitis.
Waterfowl in which the disease has been recorded. Domestic ducks and domestic geese
Dead-in-Shell Waterfowl Disease Summary Embryos are fairly fully-formed but die shortly before or during the hatching process begins.
Waterfowl in which the associated disease has been recorded.
  • Species not specified.
Early Embryonic Death (Early Embryonic mortalitity) Waterfowl Disease Summary
  • Death early in incubation, usually considered to be within the first week of incubation or the first third of incubation.
  • Eggs may apprear to be "clear" i.e. no development detected, or may show a "blood ring". If incubated for some time they may be addled.

(J23.29.w1, B42, B106, B116.11.w2)

Waterfowl in which the associated disease has been recorded.
  • Species not specified.
Mid-incubation Embryonic Death Waterfowl Disease Summary Death of the embryo in the middle period of incubation. 
Waterfowl in which the associated disease has been recorded.
  • Species not specified.

Antibiotic Use and Resistance
Antibiotic susceptibility testing should be undertaken on all coagulase positive isolates and also when a coagulase-negative isolate appears to be significant. (B21)
Listed Antibiotics recorded as having efficacy SYSTEMIC:
  • chloramphenicol (B47) (B88)
  • lincomycin (B47) (B88)
  • spiromycin (B47)
  • erythromycin (B47) (B88)
  • rifampicin (B47)
  • fluoroquinolones (B88)
  • vancomycin (B88)
  • Trimethoprim-sulfas (B88)
  • cephalosporins (first generation) (B88)
  • oxacillin (and other penicillin resistant compounds) (B47) (B88)


  • Nitrofurantoin (B47)
  • Fucidine (B47)
  • 2-chloro-4-phenol-phenol (B47)
Listed Antibiotics recorded as RESISTANCE
  • Plasmid-encoded, multiple antibiotic resistance is common and antibiotic therapy should be dependant on susceptibility testing. (B47) (B21)
  • Beta-lactamase penicillin resistance is common. (B47) (B21)
  • Commonly resistant to penicillin, streptomycin and tetracyclines. (B88)
