A questionnaire survey about on farm dairy cow mortality was carried out among veterinary practitioners in Italy between January 2013 and May 2014. The study aimed at investigating the main circumstances of death in dairy cows (euthanasia, emergency slaughter or unassisted death), the primary causes and the risk factors of death. Out of 251 dead cows involved (across 137 farms), 54.6% died assisted and 45.4% were found dead. The main causes of death were metabolic/digestive disorders (22.3%) and mastitis/udder problems (17...

In countries where bovine tuberculosis (bTB) is still prevalent the contact among different animal species in extensive systems contributes to the circulation of Mycobacterium bovis (M. bovis) and other members of the Mycobacterium tuberculosis complex (MTC). Thus, free-range pigs can develop subclinical infections and may contribute to disease spread to bovine and wildlife. Serodiagnosis has been proposed as a screening tool for detecting infected pig herds; however, the value of this method to obtain an accurate diagnosis in this species is still not clear...

The One Health concept has been extensively used to describe those practices that support transdisciplinary collaborations involving animal and human health and the environment. During the past International Society of Veterinary Epidemiology and Economics (ISVEE) conference in Merida (Mexico) in November 2015, a panel discussion was held to identify gaps and needs required for success with such approaches. Key messages included further development of dynamic, transdisciplinary collaborations, new mechanisms for obtaining, integrating and interpreting data from diverse sources, the identification of One Health joint priorities and resources for the veterinary and public health professions, and operationalization and institutionalization of One Health...

Infection with bovine viral diarrhea virus (BVDV) results in major economic losses either directly through decreased productive performance in cattle herds or indirectly, such as through expenses for control programs. The aim of this systematic review was to review financial and/or economic assessment studies of prevention and/or mitigation activities of BVDV at national, regional and farm level worldwide. Once all predefined criteria had been met, 35 articles were included for this systematic review. Studies were analyzed with particular focus on the type of financially and/or economically-assessed prevention and/or mitigation activities...

The way that an economist and an animal health professional use economics differs and creates frustrations. The economist is in search of optimizing resource allocation in the management of animal health and disease problems with metrics associated with the productivity of key societal resources of labour and capital. The animal health professional have a strong belief that productivity can be improved with the removal of pathogens. These differences restrict how well economics is used in animal health, and the question posed is whether this matters...

Tick-borne disease in dogs is common in South-east Asia and includes babesiosis and ehrlichiosis. These diseases can be largely prevented by compliant use of tick preventive products. This study investigated knowledge of ticks and tick-borne disease and use of tick preventive agents by a large sample of dog owners in Hong Kong. A total of 492 valid questionnaires were completed by owners attending veterinary practices, approached by researchers at common dog-walking areas, or targeted via local social media sites for pet owners...

The application of epidemiology in national veterinary services must take place at the interface between science and politics. Animal health policy development and implementation require attention to macro-epidemiology, the study of economic, social and policy inputs that affect the distribution and impact of animal or human disease at the national level. The world has changed fast over the last three decades including the delivery of veterinary services, their remit and the challenges addressed by public and animal health policies...

The planet's mean air and ocean temperatures have been rising over the last century because of increasing greenhouse gas (GHG) emissions. These changes have substantial effects on the epidemiology of infectious diseases. We describe direct and indirect processes linking climate change and infectious diseases in livestock with reference to specific case studies. Some of the studies are used to show a positive association between temperature and expansion of the geographical ranges of arthropod vectors (e.g. Culicoides imicola, which transmits bluetongue virus) while others are used to illustrate an opposite trend (e...

As the world continues to react and respond inefficiently to emerging infectious diseases, such as Middle Eastern Respiratory Syndrome and the Ebola and Zika viruses, a growing transdisciplinary community has called for a more proactive and holistic approach to prevention and preparedness - One Health. Such an approach presents important opportunities to reduce the impact of disease emergence events and also to mitigate future emergence through improved cross-sectoral coordination. In an attempt to provide proof of concept of the utility of the One Health approach, the US Agency for International Development's PREDICT project consortium designed and implemented a targeted, risk-based surveillance strategy based not on humans as sentinels of disease but on detecting viruses early, at their source, where intervention strategies can be implemented before there is opportunity for spillover and spread in people or food animals...

The aim of this paper is to identify risk factors associated with equine fractures in flat horse racing of Thoroughbreds in North America. Equine fractures were defined as any fracture sustained by a horse during a race. This was a cohort study that made use of all starts from the racecourses reporting injuries. The analysis was based on 2,201,152 racing starts that represent 91% of all official racing starts in the USA and Canada from 1st January 2009-31st December 2014. Approximately 3,990,000 workout starts made by the 230,034 Thoroughbreds that raced during that period were also included in the analysis...

The microbiologically and serologically-based prevalence of human enteropathogenic Yersinia spp. at moment of slaughter varies between pig farms due to different herd-level factors. A face-to-face questionnaire concerning a broad range of farm aspects (e.g., management and housing system, biosecurity, and hygiene measurements) was performed on one hundred farms. Factors influencing the seropositivity of 7047 pigs against human pathogenic Yersinia spp. were determined and compared to the microbiology. At the slaughterhouse, pieces of diafragm of on average 70 slaughter pigs per batch were sampled to determine the level of antibodies against enteropathogenic Yersinia spp...

A recent study on paratubercolosis in semi-extensive dairy sheep and goat farms in Apulia revealed a flock positivity of 60.5% and a seroprevalence of 3.0% for sheep and 14.5% for goat, with peaks of 50%. In such a context, providing detailed economic information is crucial for the implementation of a suitable control plan. In this paper we investigated the impact of Mycobacterium avium subspecies paratuberculosis (MAP) on profit efficiency of the Apulian dairy sheep and goat farms. Empirical results through a stochastic frontier model showed that the uninfected farms had a mean level of profit efficiency of 84%, which dropped to 64% in the presence of paratubercolosis as it negatively affected the productivity of feeding, veterinary and labour factors...

Vaccination is the most effective strategy for controlling Bluetongue virus (BTV) spread and economic consequences thereof. In this study we verified in sheep, using one commercially available inactivated vaccine for BTV-8 (BTVPUR AlSap 8), when, during the recommended vaccination schedule, animals start to be effectively protected against challenge with wild-type strain. To this aim, sheep were challenged at different time points shortly after the first vaccine injection. Twenty-four Sarda sheep were divided into four groups vaccinated two weeks before challenge (Group A), one week before challenge (Group B) and concurrently with challenge (Group C)...

In human and veterinary medicine, reducing the risk of occupationally-acquired infections relies on effective infection prevention and control practices (IPCs). In veterinary medicine, zoonoses present a risk to practitioners, yet little is known about how these risks are understood and how this translates into health protective behaviour. This study aimed to explore risk perceptions within the British veterinary profession and identify motivators and barriers to compliance with IPCs. A cross-sectional study was conducted using veterinary practices registered with the Royal College of Veterinary Surgeons...

AIM: At present very little information is available on antimicrobial use patterns in small animal veterinary practice in South Africa. The aim of this study was firstly to provide some indication of antimicrobial use patterns, and secondly to ascertain if the country's small animal veterinarians make use of prudent use guidelines to optimise their antimicrobial use in order to minimise the development of antimicrobial resistance. METHODOLOGY: In order to understand use patterns, a questionnaire was circulated to registered South African veterinarians, whose responses were evaluated by descriptive statistics...

Electronic medical records from first opinion equine veterinary practice may represent a unique resource for epidemiologic research. The appropriateness of this resource for risk factor analyses was explored as part of an investigation into clinical and pharmacologic risk factors for laminitis. Amalgamated medical records from seven UK practices were subjected to text mining to identify laminitis episodes, systemic or intra-synovial corticosteroid prescription, diseases known to affect laminitis risk and clinical signs or syndromes likely to lead to corticosteroid use...

The sea louse is considered an important ectoparasite that affects farmed salmonids around the world. Sea lice control relies heavily on pharmacological treatments in several salmon-producing countries, including Chile. Among options for drug administration, immersion treatments represent the majority of antiparasitic control strategies used in Chile. As a topical procedure, immersion treatments do not induce a long lasting effect; therefore, re-infestation from neighbouring farms may undermine their efficacy...
