Infection by leptospires of the Pomona serogroup in cattle and pigs in south west England.

Leptospires belonging to the Pomona serogroup were isolated from calves involved in two outbreaks of acute haemolytic disease which were characterised by jaundice, haemoglobinuria and high death rates. Retrospective case studies in which serological evidence of Pomona serogroup infection was found are also presented. Serovar pomona is the leptospire of the Pomona serogroup most commonly incriminated in clinical disease in domestic species, but the organisms isolated in this study were antigenically different to pomona and may represent a new serovar. The limited information available on the epidemiology of sporadic infection with leptospires of the Pomona serogroup in domestic species in the south west of England supports the contention that a serovar other than pomona is involved.

Sodium monochloroacetate poisoning of cattle and sheep.

Two separate incidents of poisoning, one involving the death of 10 cattle and the other four sheep following the use of sodium monochloroacetate, were investigated. The cattle drank from a farmyard drain overflow which undissolved herbicide entered. Sheep had access to spilt herbicide by a standpipe. Sodium monochloroacetate appears to be equally toxic to both sheep and cattle. The need to follow the manufacturers' instructions is emphasised.

Hyperlipoproteinemia and cerebral strokes.

Determination of lipoprotein patterns and of major plasma lipids was carried out in 171 patients with strokes. Of these, 22 had hyperlipoproteinemia (HLIPR) by paper electrophoresis and by elevation of principal plasma lipids (either cholesterol over 300 mg/100 ml or triglycerides over 200 mg/100 ml or both these components). More than two-thirds of the patients had at least one close relative with elevated blood lipids. Using criteria of the World Health Organization, these patients were classified as follows: 5 had HLIPR type IIa, 8 had HLIPR type IIb, 3 had HLIPR type III and 6 had HLIPR type IV. Phospholipids showed relatively little change from the values of normal controls. The numerical distribution of patients with stroke and HLIPR into the four different types corresponds quite well with the approximate frequency of these types of HLIPR in the general population. Thus, this study does not indicate that the patients with a particular type of HLIPR are at a greater risk to have a stroke than those belonging to other types.
