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.

Stomoxys calcitrans parasitism associated with cattle diseases in Espírito Santo do Pinhal, São Paulo, Brazil.

The stable fly has been of great significance to livestock production in the county of Espirito Santo do Pinhal; it has a painful bite, sucks blood, and carries many diseases. The aim of this study was to establish a relationship between the parasitism of Stomoxys calcitrans, manure management, cattle diseases, and technical support. According to the farmers the stable fly reaches its highest level in the rainy season, the same period in which diseases were detected. Most of the farmers said that they did not receive technical assistance. The association of inappropriate manure management, verified in this survey, with the low frequency of technical visits, resulted in a low level of technology utilization. Better technological assistance could moderate the stable fly infestation and help manage serious cattle diseases.

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.

Cerebrospinal fluid S-100B concentrations in normal and diseased cattle.

We measured the concentrations of S-100B, a marker protein used in humans to detect brain damage, in the cerebrospinal fluid (CSF) of clinically normal cattle (n=15, mean age +/- SD: 31.8 +/- 37.5 months) and of cattle with various inflammatory disorders (n=43, 70.6 +/- 31.9 months). The mean +/- SD CSF S-100B level was 2.9 +/- 1.6 ng/ml in the normal group and 7.0 +/- 7.4 ng/ml in the diseased group. Thirteen diseased cattle that had developed no obvious neurological signs showed abnormally high S-100B concentrations (> 8.0 ng/ml), whereas the two cattle with neurological disorders did not. No particular disease could be related to the S-100B rise. Therefore, it remains inconclusive whether measurement of CSF S-100B concentration is useful in veterinary neurological diagnosis.

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.
