Article: Evaluation of a wild white-tailed deer population management program for controlling chronic wasting disease in Illinois, 2003-2008[show abstract] [hide abstract]
ABSTRACT: We evaluated population management programs for controlling chronic wasting disease (CWD) in wild white-tailed deer in Illinois between November 2002 and March 2008. The intervention consisted of measures of deer removal from three deer population control programs: Illinois Department of Natural Resources culling, deer population control permits and nuisance deer removal permits. We included in the analysis a total of 14,650 white-tailed deer CWD test results. These data also included location and demographic data collected from both deer harvested in the interventions as well as deer from hunter harvests and deer vehicle collisions. We quantified intervention pressures as the number of years of intervention, the total number of deer removed and the average number of deer removed per year. We accounted for temporal and spatial variations of intervention by using mixed logistic regression to model the association between intervention pressures and CWD prevalence change. The results showed that deer population management intervention as practiced in Illinois during the study period was negatively associated with CWD prevalence and the strength of association varied depending on age of deer and the measure of intervention pressure. The population management programs showed a more consistent association with reduced CWD prevalence in fawn and yearling white-tailed deer than in adult deer. Our results also suggested that frequent and continuing intervention events with at least moderate intensity of culling were needed to reduce CWD prevalence. A longer study period, however, is needed to make a more definite conclusion about the effectiveness of similar population management programs for controlling CWD in wild white-tailed deer.

Article: The risk of a positive test for bovine tuberculosis in cattle purchased from herds with and without a recent history of bovine tuberculosis in Ireland.[show abstract] [hide abstract]
ABSTRACT: A retrospective cohort study was conducted to assess if cattle sold from Irish dairy herds within 7 months of herd de-restriction (clearance to trade) from a bovine-tuberculosis (BTB) episode had an excess risk of testing positive for BTB during the following 2 years, and to determine other risk factors associated with this outcome. If possible, a predictive metric for herds at high risk of selling future BTB-positive cattle would be generated. The unexposed cohort included all cattle sold within 7 months of the annual herd test in a random sample of dairy herds that did not test positive for BTB in 2003. The exposed cohort consisted of all cattle sold within 7 months of the date of de-restriction in all dairy herds that cleared a BTB episode in 2003. Only cattle sold from herds that were initially found to test positive for BTB using the single intradermal comparative tuberculin test (SICTT)-and not due to discovery of a BTB-positive animal at slaughter-were included as exposed cattle. To aid in the development of a predictive metric, the exposed cohort was subcategorized based on the number of reactors to the SICTT in the herd of origin during the BTB episode immediately prior to sale. The final exposure categories of 0 (unexposed), 1-7, and >or=8 total reactors were considered the unexposed, mildly exposed, and severely exposed cohorts, respectively. A multivariable logistic regression model was fit to the final BTB status of the animal using a generalized estimating equation method (GEE), assuming an exchangeable correlation structure of animals within herds, and using robust standard errors. Exposure level and the other available herd- and animal-level information were modeled. After controlling for other risk factors including the size of the herd of origin and the sex and age of the animal, the three-level exposure variable significantly improved the model (based on a change in Quasi-Akaike Information Criteria of 2.2) and demonstrated a trend of increasing risk of a future positive BTB test with increasing exposure category. The severely exposed cohort of animals had significantly higher risk of a future positive BTB test than the unexposed cohort (OR=1.78, p=0.030).Preventive Veterinary Medicine 11/2009;

Article: Comparison between dairy cow disease incidence in data registered by farmers and in data from a disease-recording system based on veterinary reporting.[show abstract] [hide abstract]
ABSTRACT: Sweden has a national disease-recording system based on veterinary reporting. From this system, all cattle-disease records are transferred to the dairy industry cattle database (DDD) where they are used for several purposes including research and dairy-health statistics. Our objective was to evaluate the completeness of this data source by comparing it with disease data registered by dairy farmers. The proportion of veterinary-treated disease events was estimated, by diagnosis. Disease incidence in the DDD was compared, by diagnosis and age, with disease data registered by the farmers. Comparison was made, by diagnosis, for (i) all disease events and (ii) those reported as veterinary-treated. Disease events, defined as "observed deviations in health, from the normal" were recorded by the farmers during January, April, July and October 2004. For the diagnoses calving problems, peripartum disorders, puerperal paresis and retained placenta, incidence proportions (IP) with 95% confidence intervals (CIs) were estimated. For all other disease problems, incidence rates (IR) were used. In total, 177 farmers reported at least 1 month and 148 reported all 4 months. Fifty-four percent of all disease events in the farmers' data were reported as veterinary-treated. For several of the most common diagnoses, the IRs and IPs for all events were significantly higher in farmers' data than in the DDD. Examples are, in cows: clinical mastitis, cough, gastro-intestinal disorders and lameness in hoof and limb; and in young stock: cough and gastro-intestinal disorders. For veterinary-treated events only, significant differences with higher IR in the farmers' data were found in young stock for sporadic cough and sporadic gastro-intestinal disorders. The diagnosis "other disorders" had significantly more events in the DDD than in farmers' data, i.e. veterinarians tended to choose more unspecific diagnoses than the farmers. This result indicates that the true completeness is likely to be higher than our estimate. We conclude that for the time period studied there was differential under-reporting associated with the diagnosis, the age of the animal and whether the herd was served by a state-employed or private veterinarian.Preventive Veterinary Medicine 02/2009; 88(4):298-307.
Article: The relationship between porcine circovirus 2 antigen score and antibody titre and histology of lymph nodes in 375 euthanased sick and healthy pigs from 113 British pig farms with and without postweaning multisystemic wasting syndrome.[show abstract] [hide abstract]
ABSTRACT: Data from a cross-sectional study of 113 British pig herds carried out in 2004 were used to investigate the associations between postweaning multisystemic wasting (PMWS) in pigs and herds and porcine circovirus 2 (PCV2) antigen score and antibody titre, and associated histological signs in lymph nodes. The sensitivity and specificity of published herd definitions for PMWS were tested on the study farms to consider the role of PCV2 in PMWS. Herds were defined as PMWS-affected, -unaffected or -recovered based on current and past postweaning mortality (PWM), grower pigs with clinical signs of rapid wasting, hairiness and pallor and no other known cause of death on the farm. PCV2 antigen and antibody were not used in the definition of PMWS. In each PMWS-affected herd, up to three sick pigs with the clinical signs above and one healthy pig of a similar age were taken for postmortem examination (PME). In all other herds at least one healthy pig was taken for PME. Lymph nodes were analysed for PCV2 antigen and histological changes, and serum samples were analysed for PCV2 antibody. PCV2 antibody was present in all the herds sampled. There was a non-linear association between PCV2 antigen and antibody. There was no association between the presence of high scores of PCV2 antigen in pigs and the presence of high PWM in herds. PCV2 antigen score was significantly higher in sick than healthy pigs within farms, and high PCV2 score was associated with giant cells, coalescence and absence of germinal centres in lymph nodes. These results did not vary by PMWS-affected, -unaffected or -recovered farms. PCV2 antigen was present at high scores in approximately 10% of healthy pigs on all farms. All three herd definitions of PMWS were highly sensitive, defining PMWS-affected herds as affected, but had a specificity ranging from 23% to 43%. We conclude that the current diagnostic tests for PCV2 indicated higher scores of virus in sick pigs but were not useful to define pigs or herds with PMWS. The ubiquity of PCV2 and the lack of specificity of the PCV2 tests indicate that PCV2 may be a necessary but not sufficient cause of PMWS disease. Linking this with the knowledge that the herd breakdowns occurred in a space time epidemic indicates that another infectious co-factor may be necessary for disease to occur.Preventive Veterinary Medicine 02/2009; 88(3):213-9.
Article: Back-calculation method shows that within-flock transmission of highly pathogenic avian influenza (H7N7) virus in the Netherlands is not influenced by housing risk factors.[show abstract] [hide abstract]
ABSTRACT: To optimize control of an avian influenza outbreak knowledge of within-flock transmission is needed. This study used field data to estimate the transmission rate parameter (beta) and the influence of risk factors on within-flock transmission of highly pathogenic avian influenza (HPAI) H7N7 virus in the 2003 epidemic in The Netherlands. The estimation is based on back-calculation of daily mortality data to fit a susceptible-infectious-dead format, and these data were analysed with a generalized linear model. This back-calculation method took into account the uncertainty of the length of the latent period, the survival of an infection by some birds and the influence of farm characteristics. After analysing the fit of the different databases created by back-calculation, it could be concluded that an absence of the latency period provided the best fit. The transmission rate parameter (beta) from these field data was estimated at 4.50 per infectious chicken per day (95% CI: 2.68-7.57), which was lower than what was reported from experimental data. In contrast to general belief, none of the studied risk factors (housing system, flock size, species, age of the birds in weeks and date of depopulation) had significant influence on the estimated beta.Preventive Veterinary Medicine 02/2009; 88(4):278-85.
Article: Assessment of the effects of supplementation with vitamin E on health and production of feedlot cattle using meta-analysis.[show abstract] [hide abstract]
ABSTRACT: Delivery of supplemental antioxidant vitamins to cattle placed in feedlots might be expected to improve health and performance outcomes by reducing the effects of oxidative stress to which these cattle are presumably exposed. Meta-analytic procedures were used in this study to assess published experiments on the effects of vitamin E supplementation in feedlot cattle. The health outcome of morbidity, and the production outcomes of average daily gain (ADG) and gain to feed ratio (G:F), were analysed. The currently available data do not support the use of supplemental vitamin E administered as an injection (morbidity risk ratio=1.17; P=0.17). The authors conclude that supplemental dietary vitamin E should be fed within the [NRC, 1996. National Research Council. Nutrient Requirements of Beef Cattle, 7th ed. Natl. Acad. Press, Washington, DC] recommended range.Preventive Veterinary Medicine 02/2009; 88(4):229-46.
Article: The role of backyard poultry flocks in the epidemic of highly pathogenic avian influenza virus (H7N7) in the Netherlands in 2003.[show abstract] [hide abstract]
ABSTRACT: In recent years, outbreaks of highly pathogenic avian influenza (HPAI) viruses have caused the death of millions of poultry and of more than 200 humans worldwide. A proper understanding of the transmission dynamics and risk factors for epidemic spread of these viruses is key to devising effective control strategies. The aim of this study was to quantify the epidemiological contributions of backyard flocks using data from the H7N7 HPAI epidemic in the Netherlands in 2003. A dataset was constructed in which flocks in the affected area were classified as susceptible (S), infected but not yet infectious (E), infectious (I), and removed (R). The analyses were based on a two-type SEIR epidemic model, with the two types representing commercial poultry farms and backyard poultry flocks. The analyses were aimed at estimation of the susceptibility (g) and infectiousness (f) of backyard flocks relative to commercial farms. The results show that backyard flocks were considerably less susceptible to infection than commercial farms (g = 0.014; 95%CI = 0.0071-0.023), while estimates of the relative infectiousness of backyard flocks varied widely (0 < or = f < or =5). Our results indicate that, from an epidemiological perspective, backyard flocks played a marginal role in the outbreak of highly pathogenic avian influenza in the Netherlands in 2003.Preventive Veterinary Medicine 01/2009; 88(4):247-54.
