Species affected: All fowl, especially turkeys, chickens, game birds, and waterfowl, are susceptible.
Clinical signs: Staphylococcal infections appear in three forms -- septicemia (acute), arthritic (chronic), and bumblefoot. The septicemia form appears similar to fowl cholera in that the birds are listless, without appetite, feverish, and show pain during movement. Black rot may show up in eggs (the organism is passed in the egg). Infected birds pass fetid watery diarrhea. Many will have swollen joints (arthritis) and production drops (see Table 3).
The arthritic form follows the acute form. Birds show symptoms of lameness and breast blisters, as well as painful movement (see Table 3). Birds are reluctant to walk, preferring to sit rather than stand.
Bumblefoot is a localized chronic staph infection of the foot, thought to be caused by puncture injuries. The bird becomes lame from swollen foot pads (see Table 3).
Transmission: Staphylococcus aureus is soil-borne and outbreaks in flocks often occur after storms when birds on range drink from stagnant rain pools.
Treatment: Novobiocin (350 g/ton) can be given in the feed for 5-7 days. Erythromycin and penicillin can be administered in the water for 3-5 days or in the feed (200 g/ton) for 5 days. Other antibiotics and drugs are only occasionally effective.
Prevention: Remove objects that cause injury. Isolate chronically affected birds. Provide nutritionally balanced feed.
Guido came up lame, dead lame. His wouldn't use his back leg at all. I'm pretty sure it was broken. Drew put him down today. I'll be processing him tomorrow so I can see if I am right.
I know he was a pain in the ass but he was sweet too. Hope he is running free with his brother now.
