Cause. Several species of flies are always ready to lay their eggs in any available wound or sore; therefore wounds must be watched in the case of poultry, as with all other animals of the farmyard. The eggs laid by these flies hatch and develop into small footless grubs commonly known as maggots.
Treatment. Wash the wound with 1 to 2% creolin; remove as many of the maggots as possible with a pair of tweezers or a feather. If the maggots are deep-seated, stuff the wound with a cotton wad saturated with strong creolin or 10% carbolic acid. Examine next day and remove dead maggots. Treat again in a similar manner if the maggots are not all killed. Fish oil, or iodoform made into a paste with vaseline, will prevent the flies depositing their eggs, if smeared on the surface of the wound.
MITES (AIR-SAC)
Not a common parasite
Symptoms. There are no definite external symptoms. If the bird is very badly affected, there may be evidences of suffocation. This may end fatally. A post-mortem examination will show the mites in the air passages and bronchi as small yellowish and whitish particles, which on careful observation may be seen to move.
Fig. 15
The Air Sac Mite(From Salmon.)
Cause. A small mite (Sarcoptes lævis) which infests the air sacs and bronchi. These mites, when present in large numbers, obstruct the air passages and cause suffocation. A secretion from the mucous membrane affected, results from the presence of the mites and increases the obstruction of the air passages.
Treatment. The fumigation method tried for gapes has been recommended, but there is little reason to expect success.
