Abstract:
To segment the pebrine from the background effectively, this paper focuses on the research of image segmentation technology on the basis of HSI color model. Owing to the complex background and poor contrast of the pebrine image, the method of contrast enhancement is adopted to improve the image quality; the technology of target extraction based on HSI model is used to realize the direct extraction of the colorized object image from the background, which utilizes the color characteristic of pebrine image; Meanwhile, the research on the threshold processing on the basis of shape feature of pebrine image can be done to improve the efficiency of algorithm, which minimizes the influence of non-target image, and the method of morphology can be applied to eliminate the hole or dot noise, and to separate the adhesive pebrines, which increases the accuracy of pebrine recognition. The result shows the method reasonable and effective.

Abstract:
Aiming to achieve the automatic detection and accurate identification of pebrine images, the fuzzy contrast enhancement algorithm was utilized to enhance the contrast of the target image in order to improve the image’s quality; Owing to the color character of light green for the pebrine, the image segmentation technique based on the HSI model can be applied to extract the pebeine image, at the same time, the morphology theory can be adopted to remove the noises such as the hole noise and point noise, and to separate the bond particles; The region labeling can be done on the binary image after the image segmentation, then the shape parameters of pebrine can be extracted, by making full use of the feature parameters, the method of neural network based on genetic algorithm is applied to recognize the pebrine image. These experiments show that the method has achieved satisfactory image recognition results.

Abstract:
With the development of the PCR technology, especially the improvement of its reagent and a method of pebrine detection by PCR in infected Bombyx mori eggs was established.With the 16sRNA gene of Nosema bombycis as target sequence, the results of extraction of genomic DNA from purified microspores showed that 1.3×10-7µg DNA can be extracted from each spore. The sensitivity detection showed the detection limit of Nosema bombycis DNA was 3.25×10-2pg, i.e. 4 spores. (PCR system volume is 25µl). The method of total DNA extraction from pebrine infected silkworm eggs just before hatching was created. The result showed that extracting total DNA from silkworm eggs after the eggs had been treated with 30% KOH met the PCR detection requirements. The result of application study showed the spores in the pebrine infected egg just before hatching can sensitively be found with PCR. The result of a group of eggs just before hatching detection showed that the maximum PCR detection level was of a pebrine infected eggs just before hatching in 300 healthy eggs when the total DNA extraction had been purified with Agarose electrophoresis. The probability of identifying groups of one pebrine spore in infected eggs just before hatching mixed with 100 healthy ones was about 80%.

Abstract:
Indonesian silk farming (Sericulture) has experienced two waves of a pebrine epidemic (also known as pepper disease) and grasserie. The first pebrine epidemic occurred in 1973 and the second one occurred in 2010. Natural silk production in Indonesia has undergone dramatic decline after these epidemics. In addition to the disease, other factors also simultaneously contributed to the decline. This research examines the conditions and challenges to national natural silk industry recovery after a pebrine epidemic. The present study employs a survey and focus group discussion in three regencies (Wajo, Soppeng, and Enrekang), which took place in September 2016. Findings show that there are three major factors which contribute to the decline of national silk production, namely the: i) epidemic of silkworm disease, ii) quality of silkworms and the process of silkworm provision, iii) insufficiency of farmer means of production, and iv) lack of guidance and assistance for the farmers. Without interventions and greater support to properly maintain silkworm operations a potentially lucrative economy for rural farmers could go unrealized. The implications of this research also highlight key potential interventions for working with communities and supporting the overall resilience of national silk production in Indonesia.

Abstract:
Abstract This article is a case study of silkworm production in Bursa in the nineteenth century. This case was chosen mainly to discuss the relationship between scientific agricultural knowledge and peasants’ knowledge. The article argues that neither type of knowledge was static and that hybrid knowledge was the product of the interaction between scientific and peasants’ knowledge. Furthermore, it analyses how scientific knowledge turned from a cure for pebrine, a disease of silkworms, into a means of standardisation and control of the peasants’ production by the government and the Ottoman Public Debt Administration so that they could increase their revenue from sericulture. In this framework, the article also discusses how peasants’ knowledge changed partly by embracing scientific knowledge and partly by resisting it.

Abstract:
No presente trabalho procede-se a uma descrição sobre os aspetos considerados mais relevantes relativos à vida e à obra do extraordinário cientista e humanista do século XIX – Louis Pasteur. Contextualiza-se, também, em vários pontos, a sua obra com a de outros cientistas da época, enquadrando os trabalhos por si realizados em descobertas anteriores. Abordam-se os magníficos estudos feitos no âmbito da cristalografia (que muito contribuíram para a moderna estereoquímica) e da fermentação, como um mecanismo utilizado por certos microrganismos para produzir energia na ausência de oxigénio, facto totalmente inédito na época. Explica-se como Pasteur, de uma forma inteligentíssima, conseguiu pôr fim à velha teoria da geração espontânea. Refere-se como surgiu a genial ideia da pasteurização, termo em homenagem ao grande sábio, que veio a modificar toda a indústria do vinho, da cerveja e de tantos outros alimentos, estabelecendo a importância da microbiologia na indústria alimentar. Abordam-se os estudos realizados por Pasteur sobre doenças infeciosas (a pebrina, a cólera das galinhas, o carbúnculo e a raiva), incluindo os espetaculares procedimentos que conduziram à elaboração das primeiras vacinas que ensinaram aos cientistas mais novos a fabricar outras, salvando-se tantas vidas.
In this paper it proceeds to a description of the aspects considered most relevant for the life and work of the extraordinary nineteenth century scientist and humanist - Louis Pasteur. It also contextualizes, at various points, his work with other scientists of that time, framing the work performed by them in previous findings. It addresses the magnificent studies within the crystallography (which greatly contributed to modern stereochemistry) and fermentation, as a mechanism used by certain microorganisms to produce energy in the absence of oxygen, a totally new fact at the time. It explains how Pasteur, in a very intelligent way, managed to put an end to the old theory of spontaneous generation. It refers to the start of the genial idea of pasteurization, term in honor of the great sage who changed all the wine industry, beer and many other foods, establishing the importance of microbiology in the food industry. It address the studies undertaken by Pasteur on infectious diseases (pebrina, cholera chickens, anthrax and rabies), including the spectacular procedures that led to the development of the first vaccine which taught the young scientists to manufacture others, saving so many lives.

Abstract:
The class or order Microsporidia was elevated in to the phylum Microspora by Sprague and Vavra (1997) and Sprague and Becnel (1998) subsequently suggested that the term Microsporidia instead be used for the phylum name. Miicrosporidia, i.e. Nosema bombycis, were first described about 150 years ago as the cause of the disease pebrine in silkworms. In 1922, there were descriptions of gram-positive spores consistent with microspordiosis in the brain of rabbits that were being used for investigations on poliomyelitis (Wright and Craighead 1922). From 1923 to 1926, Levaditi and colleagues studied the organisms seen by Wright and Craighead, which they named Encephalitozoon cuniculi, recognizing them as Microsporidia and demonstrating their lack of host specificity by transmitting infections from rabbits to mice, rats and dogs (Levaditi et al. 1923). Microsporidia were clearly confirmed of being a cause of human disease in 1959 (Matsubayashi et al. 1959), when they were isolated from the cerebrospinal fluid of a 9 year old boy with encephalitis with seizures, coma, and fever lasting about 25 days. Bergquist et al. (1984) reported a 2 year old child with encephalitis and seizures who had Encephalitozoon spores in urine and Margileth et al. (1973) isolated the microsporidium Anncaliia (Nosema) connori from a 4 month old athymic male infant who died with severe diarrhoea and malabsorption. Microsporidia can produce a wide range of clinical diseases. A diarrhoeal syndrome associated with microsporidiosis and HIV infection was reported by Desportes et al. (1985) and the number of articles describing human disease increased rapidly after 1990. In addition to gastrointestinal tract involvement, it has been recognized that Microsporidia can infect virtually any organ system; and patients with encephalitis, ocular infection, sinusitis, myositis, and disseminated infection are well described in the literature.

Abstract:
Microsporidia are obligate intracellular eukaryotic pathogens related to the Fungi that can infect both vertebrates and invertebrates. They were first identified about 150 years ago as the cause of pebrine, a disease of silkworms, with the description of Nosema bombycis in these economically important insects. They were first described in mammalian tissue samples about 75 years ago and starting 30 years ago they were recognized as pathogenic organisms responsible for a diarrhoeal syndrome in patients with AIDS. In addition to the gastrointestinal tract, it is now appreciated that microsporidia can infect virtually any organ system. The phylum Microsporidia contains about 1,400 species, distributed in 200 genera, and 15 microsporidian species have been reported in human infections.
