Genetic tools for Sulfolobus spp.: vectors and first applications

New constitutive vectors: useful genetic engineering tools for biocatalysis.

Constitutive vectors are useful tools for genetic engineering. Two constitutive vectors with high levels of expression and broad host ranges were developed and used in a range of Pseudomonas hosts. The vectors showed superior characteristics compared to the inducible vectors as well as the potential to be used as improved genetic tools for biocatalysis.

Cockroaches as Reservoirs and Vectors of Drug Resistant Salmonella spp.

Cockroaches were collected from hospitals, houses and poultry sheds in various parts of Isfahan (Iran) and identified to species. In total, seven species of cockroaches in seven genera were identified: Blatta lateralis, Polyphaga aegyptiaca, Arenivaga roseni and Parcoblatta spp. Three species Periplaneta americana, Blattella germanica and Supella longipalpa (Blattidae and Blattellidae) were mor...

Genetic requirements for the function of the archaeal virus SSV1 in Sulfolobus solfataricus: construction and testing of viral shuttle vectors.

Directed open reading frame (ORF) disruption and a serial selection technique in Escherichia coli and the extremely thermophilic archaeon Sulfolobus solfataricus allowed the identification of otherwise cryptic crucial and noncrucial viral open reading frames in the genome of the archaeal virus SSV1. It showed that the 15. 5-kbp viral genome can incorporate a 2.96-kbp insertion without loss of v...

Plasmid Vectors and Molecular Building Blocks for the Development of Genetic Manipulation Tools for Trypanosoma cruzi

The post genomic era revealed the need for developing better performing, easier to use and more sophisticated genetic manipulation tools for the study of Trypanosoma cruzi, the etiological agent of Chagas disease. In this work a series of plasmids that allow genetic manipulation of this protozoan parasite were developed. First of all we focused on useful tools to establish selection strategies ...
