RESUMO
A review of the literature on stringhalt in horses is presented, including the aetiology, clinical signs, pathology and treatment of this disease. Three New Zealand outbreaks of stringhalt are reported and discussed. The occurrence of these (and most previously reported outbreaks) in the late summer and autumn, and the association of the disease with various weeds, indicates a likely toxic aetiology.
RESUMO
The protozoan parasite, Eimeria leuckarti was present in the ileal mucosa of a 7-month-old Thoroughbred filly which was destroyed with acute peritonitis resulting from perforation of the rectum. The parasite was considered to be of no clinical significance and the signs of colic noted prior to the rectal rupture were related to the vascular lesions caused by infection with Delafondia vulgaris.

A severe gastroenteritis affected Ontario pigs in the Spring of 1964 and again in 1966. The mortality of pigs less than a week of age was 100%, in older pigs there were few deaths although morbidity in these pigs approximated 100%. Viruses were isolated from the brains, intestines, and intestinal lymph nodes of baby pigs. One of these isolates, given by mouth to two colostrum deprived piglets, induced a severe enteritis 36 hours after administration and both of the piglets died 24 hours later. The characteristics of the disease and the virus bear a striking resemblance to transmissible gastroenteritis as seen in the United States of America and the United Kingdom.
