12 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Ovine and caprine brucellosis infection is generally caused by Brucella melitensis biotype 1. It is reported that B. melitensis causes infection in cattle population as well because cattle, sheep and goats are handled together as part of the animal husbandry practices in many countries in the Eastern Mediterranean region. Zoonotic Diseases Symposium May 2011 Lefkoşa DESCRIPTION OF THE DISEASE

14 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Brucellosis is also endemic in some Mediterranean countries, namely Spain, Italy, Egypt, Portugal, Syria, Turkey, and Greece. Considering the public health risk, among all Brucella ssp, B. melitensis is the most pathogenic for humans and the most commonly isolated from human brucellosis Zoonotic Diseases Symposium May 2011 Lefkoşa DESCRIPTION OF THE DISEASE

17 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Where the B.melitensis prevalence (<%2) is low, the most appropriate method for eradication is test and culling. In countries where the prevalence (>%2) is high, Vaccination with Rev. 1 vaccine is the most cost effective way to control and eradicate the disease.

19 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Vaccination for the control of transmission of the diseases among the susceptible animals. When the disease prevalence comes to a moderate level for the country/regions, the strategy must be towards eradication of the disease through test and culling application. Zoonotic Diseases Symposium May 2011 Lefkoşa CONTROL AND ERADICATION STRATEGIES

20 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Basic principles for a succesfull control and eradiaction plan are as follows: 1-Determining diseases status -Survey studies -Efficient recoding 2- Determining the Eradication Strategy - Vaccination - Movement Control and Quarantine -Test and Slaughtering - Monitoring diseases status - Depopulation infected animal / flock - Animal waste and side product control - Diseases free certified farms - Public awareness campains Zoonotic Diseases Symposium May 2011 Lefkoşa CONTROL AND ERADICATION STRATEGIES

21 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan 2. Identification of Reactors The golden standard for diagnosing animals with active brucellosis is the reproduction of B. melitensis and/or diagnosis with the PCR. As a part of the testing and culling strategy, all animals older than six months old are tested with appropriate serological assays (e.g. RBPT, CFT and c-ELISA). Suspected cases are tested once again in one or two months. Positive animals are culled in no later than one month in registered slaughterhouses. Tissue samples (e.g. lymph nodes) are sent to a microbiology laboratory for bacteriological verification of the serological diagnosis. Zoonotic Diseases Symposium May 2011 Lefkoşa CONTROL AND ERADICATION STRATEGIES

22 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan 2. Identification of Reactors and Culling (Cont.) Lambs and goat kids of the reactors are separated from the flock. The flock is tested at regular intervals (30 to 60 days). The testing and culling process is continued until the flock is found negative in the last two consecutive tests. Negative flocks are monitored through serological tests performed initially once in every six months, and then one in every 12 months (surveillance). Approximately 5 per cent of the infected but seronegative lambs may stay seronegative until the later stages of their first pregnancy. Thus, eradication efforts based merely on testing and culling may not be sufficient. First Selected Zoonotic Diseases Symposium May 2011 Lefkoşa CONTROL AND ERADICATION STRATEGIES

23 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan 3. Control of the Animal Movements and Quarantine Quarantine measures should be applied immediately when there is a suspected brucellosis case. The quarantine may be partial or total in large enterprises practicing in various areas, depending on the flock management and prevalence of the infection. Even so, serosurveillance should be performed for different flocks of the same enterprise until infection-free status is achieved. The enterprises should take necessary measures to prevent contact with dogs and even birds that can assist in moving contaminated materials. Strict sanitation and disinfection measures should be applied for isolated animals. Suspected and risky animals should be dispatched for culling. All applications should be performed in compliance with the recommendations of the official veterinary surgeon. Declaration of the prohibition of animal movements by cordoning off will help the eradication efforts. Zoonotic Diseases Symposium May 2011 Lefkoşa CONTROL AND ERADICATION STRATEGIES

24 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan 4. Animal Waste and Side Products Control Aborted materials: Aborted foetuses, placenta of the infected animals, and other contaminating materials should be incinerated. These should be packed hygienically in plastics bags to prevent transmission to the personnel and other animals, and destroyed in rendering facilities. Disinfectans: Brucellas are sensitive to formalin of 0.03 %, phenol of 1 %, beta propiolactone of 0.01 %, sodium hypochoride, sodium hydroxide, iodines, disinfectants containing quarterner ammonium, ether and chloroform. Necessary amount of disinfectant should be available in the region. Acut brucellosis: Rapid response should be given to acute brucellosis cases, and disinfection process is performed under the supervision of the official veterinary surgeon.

25 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan 4.5. Vaccination Attenuated B. melitensis Rev.1 vaccine is used since whole-killed (dead) vaccines cannot stimulate the cellular immunity and live vaccines are better in preventing ovine and caprine brucellosis. Zoonotic Diseases Symposium May 2011 Lefkoşa 4. CONTROL AND ERADICATION STRATEGIES

26 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan 5. Vaccination B. melitensis Rev.1 vaccine Brucella melitensis Rev.1 vaccine is the most widely used vaccine for the prevention of sheep and goats brucellosis Antibodies: Antibodies disappear within four to six months in those animals subcutaneously vaccinated, while a resistance grows against the disease that will last three to five years. Vaccination time: It should be normally given to lambs and kids aged between 3 and 6 months as a single subcutaneous or conjunctival inoculation. Dose: The standard dose is between 0.5 × 109 and 2.0 × 109 Rev. 1 bacteria. Zoonotic Diseases Symposium May 2011 Lefkoşa CONTROL AND ERADICATION STRATEGIES

28 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan 4.5. Vaccination The subcutaneous vaccination induces strong antibody responses It is possible to separate between vaccinated and infected with c-ELISA. Instead, when this vaccine is administered conjunctively, it produces a similar protection without forming a persistent antibody response. Care must be taken when using Rev.1 vaccine (e.g. masks, gloves, antiseptics) since it is more pathogenic than the other vaccine strains. Rev.1 vaccine may cause abortion when animals are vaccinated during pregnancy. Therefore, adult animals should be vaccinated before mating or during the last month of pregnancy. If a mass vaccination is concerned, it is recommended to use the standard dose of Rev.1 administered conjunctively when the animals are not pregnant or during the lambing season (OIE, 2008). Zoonotic Diseases Symposium May 2011 Lefkoşa 4. CONTROL AND ERADICATION STRATEGIES

29 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Depopulation of Infected Flocks The most efficient way to eradicate ovine and caprine brucellosis is to quarantine the infected animals (M+) and all susceptible animals with high transmission risk (M1 and M2), and to cull them in a registered slaughterhouse. Disease-free (M3 or M4) enterprises should be created, and certified accordingly (78/52/EEC) Certified flocks will also be protected by biological safety measures. Their disease-free status will be monitored through serological tests to be performed once or twice in a year. Public Awareness and Media Brucellosis is a zoonotic infection The information should be provided via simple announcements, posters, internet pages, radio, TV, contact telephone numbers, forms, etc., Zoonotic Diseases Symposium May 2011 Lefkoşa CONTROL AND ERADICATION STRATEGIES

30 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan 7. Vector Control Although transmission via vectors is not important in the epidemiology of brucellosis, it is possible that cats, dogs, foxes, flies and ticks act as mechanical carriers and transmit the disease First Selected Zoonotic Diseases Symposium May 2011 Lefkoşa CONTROL AND ERADICATION STRATEGIES

31 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan 8. Establishment of Disease-Free Flocks Breeders of healthy flocks should be encouraged through provision of a Certificate for Disease-Free Status for the Brucellosis to all brucellosis-free flocks. First Selected Zoonotic Diseases Symposium May 2011 Lefkoşa CONTROL AND ERADICATION STRATEGIES

32 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan 1-Surveillance Studies There shall be survey studies as well as aetiological and serological surveys in order to identify the status of the disease.

41 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan 5.2. Sampling Methodology Determination of the sample size and sampling. Data from the Serology Laboratory of the Office of Veterinary has been taken as basis for the prevalence estimate. Prevalence of the population of the study (170 villages, 3,105 flocks, N = 206,443 sheep and N = 57,021 goats in 1,689 flocks) has been assumed 10 per cent. On the basis of this assumption, the calculation for sheep population has been made using the formula with 95 % confidence interval and 1 % error. Number of samples required has been calculated using the formula 1/n = 1/n + 1/N, and found 1/n = 1/3, /206,442 = n = 3,395. Using the same calculations, number of samples required for the goat population has been found 3,254. Zoonotic Diseases Symposium May 2011 Lefkoşa EPIDEMIOLOGY

42 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Laboratory Studies Collected blood serum samples will be tested with RBPT. CFT and c-ELISA tests will be applied to those samples that are found positive with RBPT. For microbiological samples, on the other hand, classical (isolation and identification of bacteria) and molecular methods (PCR with various primers) will be used for diagnosis on the basis of species and type. Detailed definition of the tests is given in Section 3. Zoonotic Diseases Symposium May 2011 Lefkoşa 5. EPIDEMIOLOGY

44 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Zoonotic Diseases Symposium May 2011 Lefkoşa 6. SELECTION OF THE STRATEGY STRATEGYADVANTAGESDISADVANTAGES Mass Vaccination It decreases human transmission risk. Flock immunisation is ensured in a short time. Disease is controlled in an efficient way, and disease-driven losses decrease. It is easily accepted by the producers. It is easy to organise and cost effective. Flock immunisation can be ensured with vaccination of young animals. It may cause abortion in pregnant animals. It is not possible to separate infected animals from vaccinated animals in the short term. Infected animals stay within the flock for some time more. Vaccination of Young Animals & Testing and Culling of Adult Animals It minimises the abortions caused by vaccination. Serological response of the healthy vaccinated animals helps separation of infected animals from vaccinated animals through testing. Flock immunisation is slow. Serological tests used to separate between vaccinated and infected animals are not optimum. They do not form a basis for accurate diagnosis of the disease in a single animal. Testing and Culling without Vaccination If successful, it results in elimination of the disease in the region. Diagnostic tests are more efficient, yet not optimal for unvaccinated animals. There is a risk for epidemic, followed by human infection. It is very costly. It requires effectively functioning Veterinary Services (animal identification and registry, laboratory support, control of animal movements) It is suitable only for places with low disease prevalence. Removal of the protection caused by vaccination may result in an increase in the prevalence of the disease. It may be necessary to cut all animals in a flock in order to have an effective strategy.

45 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Zoonotic Diseases Symposium May 2011 Lefkoşa IMPLEMENTATION OF THE STRATEGY The strategy for the control and eradication of ovine and caprine brucellosis in NC will be implemented on the basis of CA (competetive authority) approved plan in parallel with the following scenarios to be chosen according to the aetiological and serological prevalence studies.

46 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Zoonotic Diseases Symposium May 2011 Lefkoşa Scenario A Vaccination shall not be performed if the flock prevalence is found below 5 % and individual prevalence is found below 2 %. The eradication efforts shall then include biological safety, disinfection, control and animal movements as well as testing and culling for a duration of five years. A compansation scheme is suggested to be developed by CA. for the culling of infected sheep. Based on a calculation for 5 % flock prevalence and 1.0 % individual prevalence, it is anticipated that around 4,317 sheep and 1,180 goats (total 5,497) shall be culled. IMPLEMENTATION OF THE STRATEGY

47 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Zoonotic Diseases Symposium May 2011 Lefkoşa 7. IMPLEMENTATION OF THE STRATEGY Scenario B If the flock prevalence is found 5 % to 20 % and the individual prevalence is found between 2% and 5%, lambs and goat kids shall be vaccinated conjunctively with Rev. 1 vaccine when they are four to six months old (between June and August) for three years. This scenario targets to achieve a population immunisation of 80 % for the young animals. The vaccination campaign will continue for all lambs and goat kids (females and males) until the disease prevalence decreases down to 1 %. For the purposes of monitoring the vaccination activities, blood serums will be taken in third to fifth weeks after the vaccination, and measured for titration. It is anticipated that the flock owners, who permits vaccination of their animals, will be paid a compensation for their culled animals at a rate to be determined by the MANR (50 % - 75 %).

48 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Zoonotic Diseases Symposium May 2011 Lefkoşa 7. IMPLEMENTATION OF THE STRATEGY Scenario C If the flock prevalence is found higher than 20 % and the individual prevalence is higher than 5 %, all lambs and goat kids and adult sheep and goats shall be vaccinated for five years with Rev. 1 and Adult Rev. 1 since the transmission risk will be high in the country. Lambs and goat kids shall be vaccinated when they are three to six months old, while the adult animals shall be vaccinated 45 days after the birth or latest within one month prior to the ram / male goat addition. With this scenario, it is targeted to achieve a widespread immunisation (75 % and above) for females.

51 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Zoonotic Diseases Symposium May 2011 Lefkoşa 8. CONTRIBUTION TO REGIONAL/ NATIONAL ECONOMY Assuming 5 % flock prevalence and 1.0 % individual prevalence, ovine and caprine brucellosis causes a total of TL 3,195,480 financial loss in one year, calculated as below on the basis of basic financial losses (culling of infected sheep and goats, compensation for aborted foetuses, and destruction of milk in positive flocks). It is estimated that the annual loss will be TL 22,427,338 adding chances of sales / exportation of brood animals to the neighbouring countries in case of disease-free status (meaning an increase in the value of animals).

52 Small Ruminant Brucellosis in the northern part of Cyprus, Control and Eradication Plan Zoonotic Diseases Symposium May 2011 Lefkoşa 8. CONTRIBUTION TO REGIONAL/ NATIONAL ECONOMY Calculation Model Assumptions: Average individual prevalence for cattle, sheep and goats in NC is 1 per cent. Each animal with abortus infects five healthy animals. Average milk production is 150 litres per year for sheep and goats. Economic loss caused by abortus is TL 100 for sheep and goats. Milk price is TL 1.5 / litre for sheep and goat milk. Butchery value of normal (reactor / infected) animal is (TL … per animal): TL 350 per breeding sheep / goat TL 200 per butchery lamb With the assumption of 5 % flock prevalence: 3,105 dairy sheep flock – 190,229 sheep – flock average ,689 dairy goat flock – 51,989 goats – flock average 30.8
