CASE REPORT SULPHUR POISONING IN CATTLE R. J. JULIAN AND K. B. Introduction Sulphur, usually mixed with lard or oil, has been used topically on livestock for the treatment of fungal and parasitic skin infections for many years. Sulphur has also been used orally as a tonic and for skin conditions in man and animals. Recent reports from Russia indicate that feeding sulphur to cattle is an effective method of prevention and treatment of ringworm (3, 4). This case report describes poisoning in a group of young cattle given sulphur orally by their owner as a treatment for ringworm.

Post-mortem Examination The seventh animal to die was presented for examination. The carcass was dehydrated, and the viscera were severely congested. Specific lesions were found only in the digestive tract. There was a pronounced odour of hydrogen sulphide when the rumen was opened. Much of the rumen mucosa appeared normal and well preserved; however, severe changes were present in the wall of the dorsal sac of the rumen above the level of ingesta. In this area, the mucosa was pale with a rough, caseous appearance and was tightly adherent. The wall was discoloured, hard, and thickened with

damage to the tissues and death of the animals may be caused by one or more of several products which may be produced in the digestive tract: Hydrogen sulphide gas, which is particularly toxic to the respiratory and central nervous systems, producing histotoxic anoxia; hydrogen sulphide in solution is relatively nontoxic, but the sulphide portion produces a cathartic action in the intestine (2); sulphur dioxide gas which is a powerful irritant particularly in the respiratory tract (2) and which, in the case described, may have produced the lesion above the level of the ingesta in the rumen. (Sulphur dioxide gas produces sulphurous acid when dissolved in water, such as on moist mucous membranes. When dissolved in the ingesta of the rumen, it would be neutralized); pentathionic acid which may be the product responsible for the therapeutic activity and the keratolytic property of sulphur and which has been shown to have germicidal and fungicidal activity (2). Morbidity and mortality in the animals described here and in the outbreak described previously (1) were likely due to the combined activity of these products. The acute deaths were likely due to the action of the hydrogen sulphide on the respiratory or central nervous system following inhalation or absorption of hydrogen sulphide gas from the rumen, or possibly to absorption of hydrogen sulphide and production of. sulphhemoglobinemia. Later mortality may have been due to dehydration from diarrhea. Damage to the digestive tract and the severe colic may have been caused by sulphur dioxide (sulphurous acid) or pentathionic acid and this may have

Summary A case of sulphur poisoning is described in which 12 of 20 cattle died following the feeding of sulphur. Respiratory distress and abdominal pain were the prominent signs. Examination of one animal revealed vasculitis and necrosis of the rumen and abomasal wall. The possible toxic effects of sulphur are discussed.

killed after sampling and the extent of their pulmonary lesions assessed. The parameters measured previously could then be compared between those which had extensive, moderate or minimal pulmonary lesions. Animals with pneumonia had higher body temperatures, plasma fibrinogen levels, mean colony counts of P. hemolytica in their nasal flora but lower serum antibody levels to P. hemolytica than those without pneumonia. Some parameters were related to the extent of pilmonary lesions.

Over a period of several years range cattle were brought from Western Canada, sampled for varying periods after arrival and either resold or killed. Parameters assessed were bacterial nasal flora, serum antibody to P. hemolytica and PI-3 virus, nasal antibody to P. hemolytica and PI-3 virus, body temperature, plasma fibrinogen, in some cases leukocyte counts and plasma cortisol. Fifty animals were
