Biotechnology for developing countries. The case of the Central American isthmus.
Recent developments in the fields of chemistry, molecular biology, computer science, and communications promise to transform the way that many things will be done in the near future in diverse fields of scientific R&D. Fortunately for less developed countries (LDCs) some of the technologies involved are user friendly and safe, avoiding the need for radioactive precursors, large machines, or expensive reagents. For instance, tissue culture, polymerase chain reaction (PCR), dideoxi-sequencing, and recombinant DNA techniques have already invaded clinical laboratories, agricultural field stations, and natural history museums, even in some developing nations. Somatic cell culture for plant biotechnology and immunologic techniques for diagnosis have had wide applications for over a decade in all countries in the Central American Isthmus. More recently, recombinant DNA techniques, including PCR, have been introduced for diagnostic purposes and research at the two largest universities in Costa Rica and at other public institutions and are also used in Guatemala and Panama. Honduras and Nicaragua are only now acquiring these technologies for diagnostic purposes. Biotechnological applications in industry seem to be lagging behind, and presently no good links exist between research laboratories and industry for advanced applications. The application of biotechnologies in environmental problems is slowly underway, with molecular studies of natural wildlife populations and primary forest trees. A major effort is needed to create safe and effective ways of dealing with environmental degradation, wastes, and byproducts of tropical agriculture and industry. The creation of the National Biodiversity Institute (INBio) in Costa Rica to elaborate an inventory of flora and fauna and to prospect for useful substances provides a unique opportunity for biotechnological applications. In addition, government policies to promote biotechnological development are supported by CONICIT (National Research Council), the Ministry of Science and Technology, the newly established Costa Rican Academy of Science, and the national universities. Other countries in the region are beginning to take similar action. At the Cell and Molecular Biology Center (CIBCM) our strategy is to obtain the key components and infrastructure to handle nucleic acids and manage genetic information in databanks. Training has been an important priority during the last decade, with over 20 Central American students receiving graduate degrees in virology, molecular biology, genetics, and immunology, with support from German and Swedish governmental institutions. Diagnosis of viral diseases in cultivated plants and animals was done initially at CIBCM for research and later on a contractual basis for both the public and private agricultural sectors. DNA hybridization and PCR techniques are now replacing or being used concurrently with immunologic techniques.(ABSTRACT TRUNCATED AT 400 WORDS)
