Paratuberculosis in farmed red deer (Cervus elaphus) in Ireland.

Paratuberculosis was diagnosed in one 18-month-old and two 30-month-old hinds in a herd of 70 red deer (Cervus elaphus) in Ireland. Loss of condition and intermittent diarrhoea were the main clinical findings. Clumps of acid-fast organisms were found in the faeces of the three deer. Post mortem examination of one deer showed a slight swelling and pallor of the intestinal tract and associated lymph nodes. Histopathology showed a severe, granulomatous enteritis and lymphadenitis, with extensive cellular infiltration, notably with epithelioid macrophages containing numerous acid-fast organisms. Mycobacterium paratuberculosis was isolated from intestinal and lymph node samples. Paratuberculosis was also confirmed in one of nine clinically normal, yearling stags, sampled at slaughter. Complement fixation tests and enzyme-linked immunosorbent assays gave higher readings for clinically affected deer than healthy ones. Acid soil on the farm was believed to be a contributory cause.

Accidental carbadox overdosage in pigs in an Irish weaner-producing herd.

A weaner ration containing carbadox at concentrations of 331 to 363 mg/kg was accidentally fed to suckling and weaned pigs in an 84 sow herd. Discarded ration was fed to 36 sows. One hundred and sixty five weaner pigs died in a 10 week period with clinical signs including refusal to eat, ill thrift, the passing of hard pelleted faeces, posterior paresis and death in seven to nine days. The surviving weaners did not thrive and some males showed poor testicular development. Sows and suckling pigs that consumed the ration also failed to thrive as did the progeny of affected sows. The main pathological finding was obliteration of the zona glomerulosa of the adrenal cortex. Increased potassium and decreased sodium concentrations in serum were the most notable and consistent biochemical findings.

An outbreak of ringworm in sheep in Ireland caused by Trichophyton verrucosum.

An outbreak of ringworm in sheep in Ireland caused by Trichophyton verrucosum is described. The flock consisted of 110 sheep and two separate groups within the flock were affected. Eleven of the first group of 23 sheep and five of the second group of 25 sheep showed lesions. Contact with infected cattle and fomites contaminated by the cattle are believed to have caused the outbreak. An excellent response was obtained in both infected groups by treatment with griseofulvin at a dose rate of 7.5 mg/kg daily for seven days.
