  2. 1. Chemical genetics and immunomodulation in Salmonella enterica serovar typhimurium infection

    Author : Speranta Banesaru; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Salmonella sp. are versatile bacteria that survive and replicate in a plethora of environmental niches and hosts, including humans. The illnesses caused by various serovars in humans range from mild gastroenteritis to severe systemic disease such as typhoid fever that still cause an important number of casualties especially in developing countries.

  4. 2. Formation of Thiolated Nucleosides in tRNA in Salmonella enterica serovar typhimurium

    Author : Hans Lundgren; Glenn Björk; Charles Lauhon; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; : tRNA; modified nucleosides; thiolation; sulfur metabolism; Salmonella; Molecular biology; Molekylärbiologi;

    Abstract : The presence and synthesis of transfer RNA (tRNA) is highly conserved in all organisms and a lot of genetic material is dedicated to its synthesis. tRNA contains a large number of modified nucleosides and several diverse functions have been found but much about their function is still unknown.

  5. 3. Pharmaceutical and mutational interference with virulence of Salmonella enterica serovar typhimurium

    Author : Aurel Negrea; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Within the species Salmonella enterica are a diverse range of bacteria that can cause illness in humans and many animals. Salmonellae are extremely versatile and can adapt to a variety of environments and hosts. Typhoid and paratyphoid fever, caused by human-restricted S. enterica serovars Typhi and Paratyphi are common in the developing world. READ MORE

  6. 4. Virulence of Salmonella enterica serovar typhimurium and innate antibacterial host responses

    Author : Eva Bjur; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Salmonella; LPS; macrophages; NOS; SPI-2; thioredoxin; TrxA; TRAPC;

    Abstract : The bacterial species Salmonella enterica consists of a collection of closely related enteric bacteria giving rise to diverse diseases in a wide range of hosts. In the murine infection model Salmonella enterica serovar Typhimurium (S. Typhimurium) causes an invasive disease which in many aspects resembles human typhoid fever. READ MORE

  7. 5. Function of wobble nucleoside modifications in tRNAs of Salmonella enterica Serovar Typhimurium

    Author : Peng Chen; Glenn R. Björk; Paul Agris; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; tRNA; wobble nucleoside; frameshifting; translation; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Transfer RNA from all organisms has modified nucleosides and position 34 (the wobble position) is one of the most extensively modified positions. Some wobble nucleoside modifications restrict codon choice (e.g. 5-methylaminomethyl-2-thiouridine, mnm5s2U) while some extend the decoding capacity (e. READ MORE
