Organisation of veterinary public health activities in countries of the Eastern Mediterranean region.

This review covers the organisation of veterinary public health (VPH) activities in countries of the Eastern Mediterranean region, with reference to zoonoses and hazards to man from foods of animal origin. A study of the region shows that no separate VPH units exist within the national Veterinary Services. Although these Services are gradually being upgraded and strengthened, most of their resources are spent in controlling serious contagious animal diseases such as foot and mouth disease, rinderpest and Newcastle disease. Rabies, present in almost every country of the region, is a zoonosis which no Veterinary Service can ignore. Other serious zoonoses affecting the region include echinococcosis, brucellosis, leishmaniasis, anthrax, toxoplasmosis and tuberculosis. Salmonellosis is one of the most serious food-borne zoonoses, while hazards from the increased presence of additives, pesticides, antibiotics and hormones in foods of animal origin are other emerging VPH problems. Many obstacles hamper efficient reorganisation of VPH activities. These include the inherited colonial system of assigning VPH activities to other authorities (health inspectors) rather than to Veterinary Services; the confusion as to which authority should actually be responsible in a given field; the lack of epidemiological studies and knowledge of the real extent of VPH problems; lack of training; inadequately staffed and poorly equipped Veterinary Services; and lack of public awareness. Nonetheless, a few countries have made excellent progress in reorganising VPH activities and in eradicating serious zoonoses. International organisations like the OIE, FAO and WHO can help greatly in establishing efficient VPH programmes.

Newcastle disease in Cyprus: a review.

The first Newcastle disease epidemic in Cyprus was reported in 1949 to 1950 and between 1953 and 1959 there was a second. In November 1977 another Newcastle disease outbreak occurred. Measures implemented immediately were; quarantine of all foci of infection, destruction of diseased and in-contact birds disinfection of premises and island-wide (Government controlled) vaccination. Within a month the epidemic was brought under control. In all 47 outbreaks were recorded with the loss of about 35,000 birds. Only 2 commercial units were affected, the remaining outbreaks occurring in premises of back-yard poultry keepers. The virus was the Asiatic type.

The 1977 outbreak of bluetongue in Cyprus.

Bluetongue outbreaks, ranging from isolated cases to widespread infections, have occurred in Cyprus in about half of the years since 1924. Serious outbreaks occurred in 1924, 1939, 1943, 1946, 1951, and 1965. Most cases occurred in September, October, November and December. The last outbreak prior to 1977 was in 1969. Virus types isolated in the past were types 3 and 4. In 1977 the outbreak was serious, affecting 13.1 per cent of 27,837 in-contact sheep; these were scattered in 303 flocks of 65 villages throughout the Government-controlled area. The virus type isolated was type 4. Culicoides were involved in bluetongue transmission in the island.

The anti-echinococcosis campaign in Cyprus.

A national anti-echinococcosis campaign was started in 1971, in which education of the public, the control of dogs and the control of slaughter were emphasised. The campaign has already achieved almost total elimination of infection in food animals born subsequent to its initiation. Stray dogs are rare and all others are registered and examined three or four times a year. Infection in dogs has decreased by over 80 per cent (from 6-8 in 1972 to 1-1 in 1976). Legislation governing abattoir functioning and dog control is in force. Violation of legislation is penalised, although the level of awareness of the problem by the public, who co-operate willingly, does not often warrant this.

Vaccination of adult sheep with reduced doses of Brucella melitensis strain Rev.1: Safety and serological responses.

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.
