does anyone treat routinely twice a year for cocci? I've never heard of that.
Also got the written reports back on the necropsies. The little legbar rooster :
Necropsy Performed on: 10-9-14 The rooster weighs 0.9 kg and is bright and alert, but recumbent and
unable to stand. On necropsy the rooster is thin with atrophy of breast muscle and no internal body fat. There is
feed in the gizzard, and the crop is empty. Stifle and hock joints appear normal on cut surfaces. Leg bones
appear normal on cross-section. No other gross lesions are noted.
Histopathology: Brain: there are prominent perivascular cuffs of small lymphocytes in the cerebrum,
brainstem and cerebellar subfolial white matter.
No microscopic lesions are observed in sections of liver, kidney, sciatic nerve, trachea, proventriculus,
gizzard, crop, lung, small intestine cecum, skeletal muscle and pancreas.
Bacteriology: No pathogens isolated from liver, lung and intestine.
Diagnosis:
Moderate lymphocytic encephalitis
(Probable Marek's disease)
Marek's disease is the most likely diagnosis based on histopathological lesions in brain, the
clinical history and elimination of other viruses (Newcastle disease and avian influenza) with the potential to
produce encephalitis.
Round worms and coccidia are observed on fecal floatation. Periodic treatment of the flock for intestinal
parasites is suggested.
The hen whose eyes turned grey and the asymptomatic rooster results, with eye results pending:
Addendum: Two additional birds, one hen and one rooster were submitted on 10-17. The iris of the hen had
slightly irregular and grey borders. Otherwise no gross lesions were noted in the rooster and the hen.
Histological evaluation of the following organs from the hen and rooster were normal (liver, kidney, trachea,
gizzard, proventriculus, brain, heart, pancreas, cecum, ileum, spleen, lung). The upper small intestine
(duodenum) of both bird contains moderate numbers of coccidial oocysts and schizonts (coccidiosis).
