Rodent Animal Research in UTx
2019
The rodents, mouse, and rat represent well-characterized animal sources for basic research in any field of biological sciences. The animals are cheap compared to other type of animals, easy to husbandry, and are extremely well characterized from genetic and physiology point of views, especially when it comes to immunological and reproductive aspects. Availability of gene-modified strains, easy embryo transfer, and the accessibility of specific recombinant proteins and monoclonal antibodies are further advantages. Hence, the first experiments done in the modern era of uterus transplantation used mouse and rat as the main animal models. In this chapter, we describe important key steps of the …
Epidemiology ofSalmonella typhimurium: ribosomal DNA analysis of strains from human and animal sources
1993
SUMMARYSalmonella typhimuriumis the most frequently identified serovar ofSalmonellain Italy. This serovar is characterized by the widespread dissemination among human and non-human sources of phenotypically and genetically well-differentiated clones.In this study 457 strains ofS. typhimuriumisolated in Italy in the years 1982–91 from human and animal sources were submitted to characterization by the rDNA fingerprinting technique. Application of this typing method, after digestion of chromosomal DNA withHincII endonuclease, confirmed the greatest genetic differentiation of clones ofS. typhimurium, allowing reliable identification of 45 rDNA patterns linked into 9 major clusters. rDNA pattern…
