Overview of Cattle Diseases Listed Under Category C, D or E in the Animal Health Law for Which Control Programmes Are in Place Within Europe.

The COST action "Standardising output-based surveillance to control non-regulated diseases of cattle in the European Union (SOUND control)," aims to harmonise the results of surveillance and control programmes (CPs) for non-EU regulated cattle diseases to facilitate safe trade and improve overall control of cattle infectious diseases. In this paper we aimed to provide an overview on the diversity of control for these diseases in Europe. A non-EU regulated cattle disease was defined as an infectious disease of cattle with no or limited control at EU level, which is not included in the European Union Animal health law Categories A or B under Commission Implementing Regulation (EU) 2020/2002. A CP was defined as surveillance and/or intervention strategies designed to lower the incidence, prevalence, mortality or prove freedom from a specific disease in a region or country. Passive surveillance, and active surveillance of breeding bulls under Council Directive 88/407/EEC were not considered as CPs. A questionnaire was designed to obtain country-specific information about CPs for each disease. Animal health experts from 33 European countries completed the questionnaire. Overall, there are 23 diseases for which a CP exists in one or more of the countries studied. The diseases for which CPs exist in the highest number of countries are enzootic bovine leukosis, bluetongue, infectious bovine rhinotracheitis, bovine viral diarrhoea and anthrax (CPs reported by between 16 and 31 countries). Every participating country has on average, 6 CPs (min-max: 1-13) in place. Most programmes are implemented at a national level (86%) and are applied to both dairy and non-dairy cattle (75%). Approximately one-third of the CPs are voluntary, and the funding structure is divided between government and private resources. Countries that have eradicated diseases like enzootic bovine leukosis, bluetongue, infectious bovine rhinotracheitis and bovine viral diarrhoea have implemented CPs for other diseases to further improve the health status of cattle in their country. The control of non-EU regulated cattle diseases is very heterogenous in Europe. Therefore, the standardising of the outputs of these programmes to enable comparison represents a challenge.

Existence and Quality of Data on Control Programs for EU Non-regulated Cattle Diseases: Consequences for Estimation and Comparison of the Probability of Freedom From Infection.

Some European countries have successfully implemented country-specific control programs (CPs) for infectious cattle diseases that are not regulated or are regulated only to a limited extent at the European Union (EU) level. Examples of such diseases include bovine viral diarrhea (BVD), infectious bovine rhinotracheitis (IBR), and Johne's disease (JD). The CPs vary between countries in the design and quality of collected data as well as methods used to detect infection and estimate prevalence or probability of freedom from infection. Differences in disease status between countries and non-standardized approaches to assess freedom from infection pose a risk for countries with CPs for non-regulated diseases as infected animals may influence the progress of the disease control or eradication program. The implementation of output-based standards allows estimation and comparison of the probability of freedom for non-regulated cattle diseases in European countries. The aim of the current study was to assess the existence and quality of data that could be used for estimating freedom from infection in European countries. The online data collection tool was sent to 32 countries participating in the SOUND control COST Action and was completed by 24 countries. Data on cattle demographics and data from CPs of IBR and BVD exist in more than 50% of the response countries. However, data describing risk factors and CP of JD was reported as existing in <25% of the countries. The overall quality of data in the sections on demographics and CPs of IBR and BVD were evaluated as "good", but risk factors and JD data were mostly evaluated as "fair." Data quality was considered less good mainly due to two quality criteria: accessibility and accuracy. The results of this study show that the quantity and quality of data about cattle populations and CPs are relatively similar in many surveyed countries. The outcome of this work provides an overview of the current situation in the European countries regarding data on EU non-regulated cattle diseases and will further assist in the development and implementation of output-based standards.

Infectious Abortions in Small Ruminants: Challenges for Diagnosis and Public Health.

In this study, we report an abortion outbreak in a ruminant herd consisting of goats, sheep, and cows, with scenarios in two consecutive years. In early 2017, abortions occurred in ∼70% of goats and 66% tested positive for Coxiella burnetii (C. burnetii) and 40% of goats were positive for Chlamydophila abortus (C. abortus). In February 2018, the same herd reported an abortion rate of 75%, with 55% positive for C. burnetii, 36% for C. abortus, and 22% for Toxoplasma gondii. Six goat milk samples were positive for C. burnetii by molecular analysis. Three family members were positive for C. burnetii. C. burnetii could be considered as the main cause of abortions in the first and second year. Animals that undergo an infection and abortion are prone to secondary infections. Vaccination or other rapid interventions should be initiated to protect animals and humans.

Serological and clinical survey of Canine Leishmaniasis in Southwestern Region of Kosovo.

Canine Leishmaniasis caused by Leishmania infantum is endemic in Mediterranean countries. The disease represents an important public health issue in Kosovo in which the autochthonous cases by humans were reported in the last years. The objective of this study was to survey the serological and clinical data of Canine Leishmaniasis in dogs in southwestern region of Kosovo. The blood samples were collected from stray dogs in four municipalities, respectively Prizren, Gjakova, Rahovec and Deçan. The total 125 samples were collected between April/September 2016. Antibodies of Leishmania infantum were detected by competitive enzyme-linked immunosorbent assay (ELISA IgG). Out of total 125 serum samples, 23 dogs (18.4%) were positive for Leishmania infantum. In three of 23 infected dogs (13%) were shown the clinical signs of Canine Leishmaniasis as skin and ocular lesions, decreased appetite, lameness, diarrhea, lethargy and progressive weight loss. The highest infection rate was detected in Prizren municipality (21.6%), followed by Gjakova (17.6%), Rahovec (17.1%) and Deçan (7.8%). The present study confirmed that the Leishmaniasis is endemic in southwestern part of Kosovo and emphasized the need to establish the surveillance and control of this disease.
