TL;DR: In this paper, the initial phase of the 2001 foot and mouth disease (FMD) outbreak in the UK, before the ban on animal movements was imposed, is analysed descriptively using SNA.

TL;DR: Proportionally, the most often applied oral antimicrobial drugs were: doxycycline, amoxicillin, combination trimethoprim-sulphonamides and polymyxin E.

TL;DR: It is concluded that housing calves in groups of under 10 calves is preferable from a health and growth perspective.

TL;DR: Heterogeneity in movements between farms should be used to evaluate the risk potential of disease transmission for each premise and must be considered when modelling disease spread between premises.

TL;DR: Existing systematic reviews on agri-food public-health topics revealed a scarcity of rigorously conducted intervention research, indicating a need for additional high quality primary studies.

TL;DR: The results of the neutering campaign from 1991 to 2000; and a survey, on 103 cat colonies, on the effects of demographic control of urban feral-cat colonies in the city of Rome, are presented.

TL;DR: Termination of AGPs was only a temporary risk factor for increased usage of therapeutic antimicrobials in food-animals in Sweden and Denmark; however, an exception might be usage in weaning piglets in Denmark.

TL;DR: Investigating the possible impact of dilution and inflammation on the association between somatic cell count and yield found that dilution-adjusted SCC values fitted the data better and resulted in a slightly lower milk loss per SCC category compared with un adjusted SCC.

TL;DR: Results of this study suggest that several risk factors may explain why dairy cattle in Brazil may become exposed to N. caninum, and further investigation of these factors is necessary.

TL;DR: Even though tick resistance to amitraz is a present problem there was no evidence that it was associated with the risk factors analyzed in this survey.

TL;DR: Four alternatives to the existing Danish control strategy for Salmonella in pork were compared in a cost-benefit analysis and only hot-water decontamination was socio-economically profitable.

TL;DR: It is found that the odds of a flock being positive for Campylobacter spp.

TL;DR: It is shown that liquid-feeding and all-in all-out management of the grower-finisher barns can reduce the Salmonella prevalence, and dry- feeding and continuous flow system increased risk of finding Salmoneella in the individual pig.

TL;DR: The model demonstrates that improving herd management practices to control infection spread (hygiene) is often more cost-effective than testing; not all herds should test as part of a paratuberculosis control program.

TL;DR: The effects of risk factors and control policies following the highly pathogenic avian influenza (HPAI) epidemic that struck northern Italy's poultry industry in the winter of 1999-2000, where flock density was highest, were evaluated.

TL;DR: It was concluded that the incidence of diarrhoea and CRTD in 91-210-day-old Swedish dairy calves is higher than previously reported from dairy herds in Sweden and the USA, and that diarrhoeA, increased respiratory sounds andCRTD are associated with season, a history of disease during the first 90 days of age and, to some extent, housing factors.

TL;DR: Cow test day somatic cell counts were categorised according to the magnitude of change since the previous test day reading, to examine which categories were responsible for the summer increase, and Markov chain Monte Carlo methods provided a valuable and flexible platform for parameter estimation in reasonably complex multilevel models.

TL;DR: In this article, the authors evaluate the problem in Sierra de San Pedro, estimating the prevalence of TB in wild boar and red deer, the main wild artiodactyls in the area, and domestic cattle since 1992-2004, by the use of a low-cost surveillance method based on detailed pathological inspection of hunted animal carcasses.

TL;DR: Findings from a nested case-control study investigating factors associated with the occurrence of pelvic and tibial stress fractures in Thoroughbred racehorses in training in the UK suggest surface maintenance and construction may play a role.

TL;DR: Pigs from herds with only dry feeders had five-fold higher odds of testing Salmonella positive when compared with pigs from herd with combinations of wet/dry style feeders, and interventions at these two points should be considered when designing growing pig facilities to reduceSalmonella shedding.

TL;DR: Ring vaccination (when used with either limited or extended pre-emptive depopulation) reduced both the size and variability of the predicted number of infected farms, and reducing the time between disease incursion and commencement of controls had the greatest effect.

TL;DR: The methods presented offer a means of evaluating and understanding the various factors that can influence overall accuracy of PST procedures, and effects of the following factors on the overall PST sensitivity and specificity: dilution (pool size), cross-contamination, and cross-reaction.

TL;DR: Based on the interpretation of the final model, it is suggested that a minimum of 50h spent outdoors over a 4-week period is necessary to have a marked result on the prevalence of hock lesions.

TL;DR: The homogeneous model indicates that the critical community size for the persistence of CBPP falls within the typical herd sizes for pastoral communities in East Africa suggesting that individual isolated herds are capable of maintaining infection indefinitely.

TL;DR: Drought climatic conditions in conjunction with a greater awareness among farmers could be responsible factors for the prevalence and long-term trend of liver fluke disease in sheep, cattle and goats in the Fars province.

TL;DR: This paper provides condensed literature review and contextual information concerning antimicrobial use in animals and antimicrobials use data collection techniques in the United States.

TL;DR: The negative predictive value of the California Mastitis Test was >95% for herds with major-pathogen intramammary-infection prevalence <15%, so that selective dry-cow therapy might be reasonable for such herds if cows were screened with the CMT.

TL;DR: The present study was conducted to estimate the direct losses due to Neospora caninum in Swiss dairy cattle and to assess the costs and benefits of different potential control strategies.

TL;DR: It was concluded, from the level of polyparasitism evident in this study, that adult cattle should be considered in preventative approaches to bovine helminthosis.

TL;DR: It is demonstrated that both clinical and subclinical mastitis is common in smallholder dairying in Tanzania, and that some of the risk and protective factors for mastitis can be addressed by practical management of dairy cows following effective knowledge transfer.
