Development & Application of Computer Diagnosis, Prevention and Treatment Expert System on Sheep and Goat Disease
Progress in Veterinary Medicine, 2003Co-Authors: Li ShuAbstract:Experts have paid great attention to impart their knowledge experience with no time and regional limitation to help the peasant households in the diagnosis, prevention and treatment of sheep and Goat Disease. This study, a computer diagnosis, prevention and treatment expert system is established by adoption Visual Prolog Delphi etc. The symptom, diagnosis, prevention and treatment over 290 sheep and Goat Diseases have been entered into the knowledge base. Then the diagnosis is made through positive deduction. Last the corresponding prevention and treatment plan is available. The system has been put into use and obtains the anticipated effect.

Characterization of the 16S rRNA genes from Mycoplasma sp. strain F38 and development of an identification system based on PCR.
Journal of bacteriology, 1994Co-Authors: C R Bascuñana, Jens G. Mattsson, Göran Bölske, Karl-erik JohanssonAbstract:Mycoplasma sp. (strain F38) is the causative agent of contagious caprine pleuropneumonia, which is a Goat Disease of great global concern. Strain F38 belongs to the so-called "Mycoplasma mycoides cluster," and the members of this cluster have many biochemical and serological properties in common, which makes it difficult to differentiate between them by conventional methods. Their phylogenetic interrelationship are thus uncertain. The 16S rRNA gene of the rrnB operon from strain F38 was cloned and sequenced. The sequence was compared with the 16S rRNA sequences of related mycoplasmas, and phylogenetic trees were constructed by parsimony analysis. A three-way ambiguity among strain F38, Mycoplasma capricolum, and Mycoplasma sp. strain PG50 was observed in the trees. This observation is in agreement with a recent proposal to reclassify strain F38 and M. capricolum. A primer set was designed for in vitro amplification by PCR of a fragment of the 16S rRNA genes from the M. mycoides cluster. The amplimers of strain F38 could be distinguished easily from the corresponding amplimers from other members of the M. mycoides cluster by restriction enzyme analysis with PstI. This observation was utilized to design an identification system for strain F38. Part of the 16S rRNA gene of the rrnA operon from strain F38 was also cloned, and several sequence differences between the two rRNA operons were discovered, revealing microheterogeneity between the two 16S rRNA genes of this organism.

pastoralist knowledge of sheep and Goat Disease and implications for peste des petits ruminants virus control in the afar region of ethiopia
Preventive Veterinary Medicine, 2020Co-Authors: Bryony A Jones, Adem Muhammed, Katherine Homewood, D U PfeifferAbstract:Abstract Pastoralist areas of Ethiopia are vulnerable to drought, causing livelihood loss and famine. One approach to increasing pastoralist resilience is the control of livestock Disease, but there is limited information from pastoralist areas to inform control strategies. This study aimed to explore pastoralist concepts of small ruminant Disease and implications for infectious Disease surveillance and control in the pastoralist Afar Region. During 2013–14, qualitative and quantitative methods were applied in two villages of one district in the mid-west of the region. Semi-structured group interviews, incorporating participatory tools, explored pastoralist knowledge of small ruminant Diseases and their impact. These were followed by multiple visits in different seasons to 70 households for semi-structured and informal interviews, observation of management practices, clinical examinations, and weekly questionnaires of mortality and morbidity. Thematic analysis was applied to interview transcripts and field notes, and descriptive statistical analysis to quantitative data. Afar concepts of Disease causation, terminology and treatment were predominantly naturalistic, related to observable signs and physical causes, rather than personalistic factors (misfortune due to magical or spiritual agents). Disease occurrence was associated with malnutrition and adverse weather, and Disease spread with contact between animals during grazing, watering and migration. Disease occurrence varied by season with most syndromes increasing in frequency during the dry season. Names for Disease syndromes were related to the main clinical sign or body part affected; 70 terms were recorded for respiratory syndromes, diarrhoea, sheep and Goat pox, lameness, skin Diseases, ectoparasites, urinary and neurological syndromes and abortion. Some syndromes with pathognomonic signs could be linked to biomedical diagnoses but most were non-specific with several possible diagnoses. The syndromes causing greatest impact were diarrhoea and respiratory Disease, due to mortality, reduced milk production, weight loss, abortion, weak offspring and reduced market value. Afar applied a range of traditional methods and modern medicines to prevent or treat Disease, based on livestock keeper knowledge, advice of local specialists and occasionally advice from district veterinarians or animal health workers. In relation to surveillance for peste des petits ruminants (PPR), several terms were used for PPR-like syndromes, depending on the predominance of respiratory or diarrhoea signs. Therefore, whenever these terms are encountered during surveillance, the associated Disease events should be fully investigated and samples collected for laboratory confirmation. The Afar naturalistic concepts of Disease parallel biomedical concepts and provide a good foundation for communication between veterinarians and pastoralists in relation to PPR surveillance and control measures.

Research on diagnosing Disease method based on model of back propagation neural network
Computer Engineering and Design, 2011Co-Authors: Wang Jing-renAbstract:The similarity and difference between the AI course about training BP network is analyzed then solving problem and the physi-cal course about human expert learning,diagnosing then curing Disease in detail,and a diagnosing model based on the BP network CF knowledge rules is proposed,and the method of standardizing clinic presentation is designed and that of the transition from CF rules to training numeric vector samples,and an algorithm of diagnosis on the base of BP network is constructed at last.The data derived from some contrast diagnosis experiments about Goat Disease between the model and human experts demonstrate that: the model be able to reach 90% at diagnosis accurate and present a favorable overall performance,and bear a thick constructive significance to develop practical AI auxiliary Disease system.
