Epidemiology of ovine listeriosis in Great Britain.

A retrospective study of 75 sheep flocks affected with listeriosis during January to June 1982 was made. Seven flocks experienced more than one form of listeriosis. Encephalitis was the commonest form, occurring in 60 flocks, and only lambs were affected in 10 of these flocks. In the remaining 50 flocks only single cases in adults were recorded in eight flocks. The mean attack rate for encephalitis in adults was 2.5 per cent. Listeric abortions occurred in 18 flocks and was the only form of listeriosis in 13 flocks. Silage was fed in 59 of the affected 60 flocks. A significant association between silage feeding and the development of listeric encephalitis was found in these flocks with the estimated relative risk being 3.8. Winter housing was not found to be associated with the development of listeric encephalitis.

Experimental infection of pregnant ewes with Listeria monocytogenes.

Eight 18-month-old ewes were infected orally with Listeria monocytogenes between 77 and 91 days of pregnancy. Only one ewe aborted, 10 days after the first infecting dose, at 94 days of gestation; L monocytogenes was isolated from several sites in both its aborted fetuses. Two days after the first infecting dose all the ewes exhibited mild illness and pyrexia lasting for two to three days but the ewe which aborted was seriously ill until nine to 10 days after aborting. Agglutination tests carried out on 2-mercaptoethanol reduced sera revealed a strong immunological response in all the infected ewes but in the ewe which aborted this response was delayed. Four uninfected ewes which were kept as controls remained healthy throughout the experiment and showed no evidence of 2-mercaptoethanol resistant antibodies to L monocytogenes. Growth retardation lines, occurring at the time of and after experimental infection, were found in the bones of 14 of 17 newborn lambs in both the infected and control groups; in the aborted lambs these lines occurred before the infection.

Nutritional myodegeneration in dairy cows.

A syndrome is described in which parturient dairy cows showed clinical signs consistent with milk fever but failed to respond to conventional therapy. The affected cows were reluctant to walk, moved stiffy and in severe cases became recumbent. The condition was apparently precipitated by low vitaimin E and selenium intake, stress of pregnancy and in one outbreak erratic feeding. Skeletal and cardiac myodegeneration were observed grossly and histologically but an almost full term fetus from an affected cow showed no muscle lesions. A high incidence of retained placentae was also recorded.

Listeria monocytogenes in "oven-ready" poultry.

Listeria monocytogenes was isolated from 10 out of 68 "oven-ready" poultry (ie, 14-7 per cent) purchased at 26 different shops and supermarkets. The organisms belonged to type 4 and 1/2; from one chicken both serotypes were isolated.
