Participatory analysis of seasonal incidences of diseases of cattle, disease vectors and rainfall in southern Sudan.

During an investigation into a chronic wasting disease in southern Sudanese cattle, a participatory appraisal method called a 'seasonal calendar' was used to understand local perceptions of seasonal variations in cattle diseases, disease vectors, intermediate hosts and rainfall. Repetition of a standardized seasonal calendar with Dinka informants demonstrated good reproducibility of the method. Comparison of rainfall data produced by seasonal calendars and objective measures of rainfall demonstrated good validity of the seasonal calendar method. Subjective assessment of seasonal calendar scoring patterns by veterinarians indicated that herders' perceptions of seasonal populations of biting flies, ticks and snails were similar to modern veterinary knowledge. The uses of seasonal calendars in veterinary epidemiology are discussed.

Clinical variation in foot and mouth disease: cattle.

Foot and mouth disease (FMD) in cattle is usually clinically obvious in the unvaccinated herds of countries in which the disease occurs only occasionally. However, in vaccinated herds and in some breeds indigenous to areas in which FMD is endemic, the disease may circulate undetected.

Survey of antimicrobial resistance in bacterial isolates from diseased cattle in France.

Since 1982, a national veterinary network has been involved in the monitoring of resistance to antimicrobial agents in the main pathogenic bacteria isolated from diseased cattle in France. It is based on 40 regional veterinary diagnostic laboratories and managed by a central reference laboratory (CNEVA Lyon). Highly standardized methods are used in the diagnostic laboratories. This network collects up-to-date information on antimicrobial resistance in veterinary isolates and gathers strains for specific studies on fastidious bacteria and for the analysis of mechanisms of resistance to antibiotics. Such a permanent survey is essential to establish a rational veterinary antibiotic policy. It could be connected to other compatible systems developed in other fields such as human medicine, food, and environment, to evaluate the importance of resistance and R-factors spread for public health. The limits and perspectives of this surveillance system are discussed.

Geographical information systems for studying the epidemiology of cattle diseases caused by Theileria parva.

Data on selected variables which influence the epidemiology of cattle diseases caused by Theileria parva were assembled and entered in a computerised geographical information system. Variables studied included the distributions of major hosts (cattle and buffalo), the vector ticks (Rhipicephalus appendiculatus and related species) and the reported presence of East Coast fever, corridor disease and January disease. In addition, the distribution of climatic suitability for R appendiculatus was assessed using the model CLIMEX run on an interpolated climate database developed for Africa. Distribution maps of each variable were produced. The potential value of geographical information systems in studies of disease epidemiology and control is discussed, with examples of how sensitivity may be enhanced by the inclusion of additional variables. In addition, subject areas in which poor data quality and inadequate data standardisation may limit the use of these systems are identified and discussed.

Serum apolipoprotein B-100 concentrations in healthy and diseased cattle.

The purpose of this study was to establish the normal range of serum apolipoprotein B-100 (APO B-100) concentration in clinically normal cattle, and to assess its abnormalities with clinical diseases. We measured the serum concentration of APO B-100 in cattle of varying ages, breeds and sex, maintained under normal field conditions. Blood samples were obtained from 735 apparently healthy cattle and 146 cows with various diseases. The concentration of serum APO B-100 in cattle was assayed by the single radial immunodiffusion method. The concentration of serum APO B-100 in healthy adult breeding bulls (mean +/- SD: Holstein; 101 +/- 46 microg/ml, Japanese Black; 106 +/- 46 microg/ml) was significantly (P<0.001) lower than that in cows (Holstein; 259 +/- 63, Japanese Black; 210 +/- 46 microg/ml), while that of APO B-100 in steers (Holstein; 290 +/- 86 microg/ml, Japanese Black; 302 +/- 90 microg/ml) was similar to the level in cows. The concentration of serum APO B-100 in cattle varied with sex and breed. APO B-100 concentration in cattle was decreased in association with metabolic disorders such as ketosis, displaced abomasum and fatty liver. From these results, it is assumed that the level of serum APO B-100 will be applied to diagnosis of metabolic diseases in cattle.
