RESUMO
A trial was made to test the safety of a Brucella melitensis strain Rev. 1 vaccine when used in various doses on pregnant sheep and a control group of pregnant goats. It was found that local sheep were more susceptible than goats to the effects of this vaccine, and that the accepted dosage rate of 10+5 viable organisms, as recommended for adult goats, should not be used on pregnant sheep.

Seventy-eight British soldiers stationed in the Eastern Sovereign Base Area (ESBA) in Cyprus contracted Q fever in the period December 1974 to June 1975. Pneumonia developed in 59% of cases. Of 31 patients tested, 81% had biochemical evidence of hepatitis although only one became clinically jaundiced. Three patients (4%) suffered pericarditis. Treatment with tetracycline had no apparent effect on the course of the disease. Investigation revealed an abortion epidemic involving 21 mixed flocks of sheep and goats in the south-eastern coastal region. 11 of the flocks grazed in and around the ESBA. A serological survey of 10 affected flocks, and evidence collected from previous years, indicated that the abortion epidemic was the result of infection with Coxiella burneti. Infection in the humans was almost certainly acquired by inhalation of dust from brush contaminated with rickettsial parturition products of the aborting flocks. A human serological survey revealed a number of cases of subclinical Q fever in a susceptivle military population, and an asymptomatic epidemic in a largely immune local position.

The eradication of ox warble fly from Cyprus is described. Initially, the major part of the eradication consisted of dressing every bovine animal with derris at monthly intervals between December and May (inclusive), but in the final and critical stages when the level of infestation had fallen to 0-2 per cent, it was found that the most efficient and economical approach was to offer a financial reward to any stock-owner reporting the presence of warble fly.
