Yeah it is Deb, I'll copy the post from the person's FB page, it's really heartbreaking, she's lost 60 birds that she recently bought in that were infected and already lost nearly 50 of her own birds, it appears that the big problem is that the eggs can hang around and cause reinfestation. Sounds like a horrible situation, she's working with vets but it's always worth looking at other's opinions and experiences.
Quote from her FB page
this is what is happening in my stud right now
worms are a big deal
don't underestimate the short time they can infect your birds
Large Roundworms (dsearidia spp.):
Ascaridia hermaphrodita and closely related roundworms are common in psittacines, especially the larger Australian parakeets. Their importance as a cause of disease in these birds has only recently been realized. The very similar Ascaridia columbae is common in pigeons and A. galli in gallinaceous birds. The worms, which are probably cosmopolitan in distribution are easily visible to the naked eye on post-mortem examination or when they are passed in the feces. They can measure as much as 10 cm. in length, are whitish in colour and round in cross section, being about as thick as an ordinary pin. The life cycle of the worm is direct. The eggs are passed in the feces and the larvae develop in the egg outside the body of the bird. Within 1 to 2 weeks the eggs become infective to the host, but they can remain viable for over three months under suitable conditions of warmth and moisture. Direct sunlight kills the eggs, however. When the eggs are ingested by a suitable host the larvae are released in the small intestine. The larvae live in the gut and also penetrate the wall of the intestine. After moulting they reach the adult stage, produce eggs and the cycle is repeated. Young birds of most species are more susceptible to infestation than adults, but in parakeets this is not necessarily the case. Parakeets lose condition and may develop apparent paralysis of the legs, because the worms in these birds most frequently cause trouble by impacting and blocking the small intestine. In a small parakeet, only a few worms may produce trouble, since they are relatively large and often difficult for the bird to pass; this is because the diameter of the lower part of the small intestine is smaller than that of the duodenum where the worms are most frequently found.
birds then fall ill to septicemia causeing the lining of gut to become infected and birds dieing due to worms not being able to be passed
in turn causeing very quick transference of cross infection to whole stud
Adult birds are more susceptible. In parental flocks, cocks are far more susceptible than hens.
Treatment
The most efficient treatment in breeding flocks or laying hens is individual intramuscular injections of a long-acting tetracyclines, with the same antibiotic in drinking water, simultaneously. The mortality and clinical signs will stop within one week. But the bacteria might remain present in the flock.
Clinical signs and post-mortem lesions
In acute cases, a green diarrhoea can be an early symptom.
The most typical symptom, in chronic cases, is the swelling of the wattles. It is more frequent in resistant local breeds. Rather than a general infection, localized infections are more characteristic. These often occur in the respiratory tract including the sinuses and pneumatoics bones, hock joints, sternal bursa, foot pads, peritoneal cavity and oviducts.
In acute cases, the most typical p.m. lesion is the petechiae observed in the epicardial fatty tissue. Necrotic foci on liver are usually found and general hyperemia is common. Due to the speed of infection and mortality, birds are in good body condition and do not exhibit the signs of prolonged illness.
no guarantee birds will ever be well and decision to cull whole flock left in my hands
does anyone have any ideas about this or experience themselves help would be much appreciate links infor people whom have delt with it all welcome
