Staphylococcus aureus has clustered tRNA genes.
The polymerase chain reaction (PCR) was used to detect large tRNA gene clusters in Bacillus subtilis, Bacillus badius, Bacillus megaterium, Lactobacillus brevis, Lactobacillus casei, and Staphylococcus aureus. The primers were based on conserved sequences of known gram-positive bacterial tRNA(Arg) and tRNA(Phe) genes. This PCR procedure detected an unusually large tRNA gene cluster in S. aureus...
متن کاملDetection of Staphylococcus Aureus Enterotoxin Genes A-E
Abstract Background and Objective: The main cause of spreading staphylococcal infections among patients is the healthy carriers working in hospitals. With the secretion of different sorts of toxins such as entrotoxin, this bacteria can provide the conditions for attacking on the host. The main objective of this study is identification of the characteristics and differences in the Staphylococc...
متن کاملPanton-Valentine Leukocidin Genes in Staphylococcus aureus
To the Editor: The pathogenicity of Staphylococcus aureus depends on various bacterial surface components and extracellular proteins. However, the precise role of single virulence determinants in relation to infection is hard to establish. The frequent recovery of staphylococcal isolates that produce leukocidal toxins from patients with deep skin and soft tissue infections, particularly furuncu...
متن کاملRelaxed tRNA specificity of the Staphylococcus aureus aspartyl-tRNA synthetase enables RNA-dependent asparagine biosynthesis.
The human pathogen Staphylococcus aureus is an asparagine prototroph despite its genome not encoding an asparagine synthetase. S. aureus does use an asparaginyl-tRNA synthetase (AsnRS) to directly ligate asparagine to tRNA(Asn). The S. aureus genome also codes for one aspartyl-tRNA synthetase (AspRS). Here we demonstrate the lone S. aureus aspartyl-tRNA synthetase has relaxed tRNA specificity a...
متن کاملThe Frequency of Staphylococcus aureus Classical Enterotoxin Genes in Raw Milk Samples in Zanjan, Iran
Background: Staphylococcus aureus is one of the major causes of food poisoning. Since milk is a nutritious source of proteins and vitamins, it could provide the optimal conditions for the growth of several bacterial pathogens, such as S. aureus. The present study aimed to assess the frequency of Staphylococcus aureus classical enterotoxin genes in raw milk samples in Zanjan, Iran. Methods: In ...
