A review of network analysis terminology and its application to foot-and-mouth disease modeling and policy development. Dubé, C., Ribble, C., Kelton, D., McNab, B. (2009).  Transboundary and Emerging Diseases, 56: 73-85.

Summary:  Livestock movements are important in spreading infectious diseases and many countries have developed regulations that require farmers to report livestock movements to authorities. This has led to the availability of large amounts of data for analysis and inclusion in computer simulation models developed to support policy formulation. Social network analysis has become increasingly popular to study and characterize the networks resulting from the movement of livestock from farm-to-farm and through other types of livestock operations.  Network analysis is a powerful tool that allows one to study the relationships created among these operations, providing information on the role that they play in acquiring and spreading infectious diseases, information that is not readily available from more traditional livestock movement studies. Recent advances in the study of real-world complex networks are now being applied to veterinary epidemiology and infectious disease modeling and control.  A review of the principles of network analysis and of the relevance of various complex network theories to infectious disease modeling and control is presented in this paper.

Factors associated with the early detection of foot-and-mouth disease during the 2001 epidemic in the UK.  McLaws, M., Ribble, C.S., Martin, S.W., Wilesmith, J. (2009). Canadian Veterinary Journal. 50: 53-60.

Abstract: An essential objective of an effective foot-and-mouth disease (FMD) eradication campaign is to shorten the infectious period by rapidly detecting and destroying cases of disease. The purpose of our investigation was to identify factors associated with the early detection of clinical FMD during the 2001 outbreak in the United Kingdom. We performed a logistic regression analysis, using early versus late detection of disease as the outcome of interest.  During the 2001 FMD outbreak in the United Kingdom, infected premises were more likely to be detected early under the following circumstances: 1) cattle (particularly dairy) were infected rather than sheep; 2) a recently confirmed infected premises was within 3 km of the new case; and 3) the case was initially reported by the farmer, rather than a Local Disease Control Centre-initiated surveillance activity (patrol, tracing, pre-emptive cull). Our findings suggest that reporting by farmers and initiatives that increase farmer education and awareness should be encouraged.

Identification, characterization and deduced amino acid sequence of the dominant protease from Kudoa paniformis and Kudoa thyrsites: A unique cytoplasmic cysteine protease.

Abstract: Kudoa paniformis and Kudoa thyrsites (Myxozoa: Myxosporea) infections are associated with severe proteolysis of host muscle tissue postmortem.  The present study was undertaken to identify and characterize the protease responsible for myoliquefaction and determine mechanisms controlling protease function in vivo. N-terminal sequence analysis of partially purified protease from hake muscle infected with K. paniformis and K. thyrsitesK. paniformis amino acid sequence data, a corresponding cDNA sequence from K. thyrsitesKth-CL). The translated amino acid sequence lacked a signal sequence characteristic of lysosomal and secreted proteins suggesting a unique cytoplasmic location. Only the proenzyme form of Kth-CL was present in Atlantic salmon muscle anti-mortem but this form became processed in vivo when infected muscle was stored at 4 °C. The proenzyme of Kth-CL showed uninhibited activity at pH 6.0, negligible activity at pH 6.5 and no measurable activity at pH 7.0 whilst the processed protease showed stability and function over a broad pH range (pH 4.5–8.8). The pH dependent processing and function of Kth-CL was consistent with histidine residues in the proregion playing a critical role in the regulation of Kth-CL.
