Simple sequence repeats in Haemophilus influenzae
Simple sequence repeat (SSRs) of DNA are subject to high rates of mutation and are important mediators of adaptation in Haemophilus influenzae. Previous studies of the Rd KW20 genome identified the primacy of tetranucleotide SSRs in mediating phase variation (the rapid reversible switching of gene expression) of surface exposed structures such as lipopolysaccharide. The recent sequencing of the...
متن کاملDNA repeats identify novel virulence genes in Haemophilus influenzae.
The whole genome sequence (1.83 Mbp) of Haemophilus influenzae strain Rd was searched to identify tandem oligonucleotide repeat sequences. Loss or gain of one or more nucleotide repeats through a recombination-independent slippage mechanism is known to mediate phase variation of surface molecules of pathogenic bacteria, including H. influenzae. This facilitates evasion of host defenses and adap...
متن کاملHaemophilus Influenzae B
یکی از شایع ترین مننژیت باکتریایی در شیرخواران، هموفیلوس آنفلوانزا از نوع B (HIB) می باشد. به منظور تهیه و عرضه واکسنی جهت حفظ کودکان در مقابل این بیماری به بازار جهانی، تحقیقاتی انجام و نوعی واکسن در بخش تحقیقاتی آکسفورد مورد آزمایش و ارزیابی قرار گرفت تا در صورت تمایل والدین و کارکنان بهداشتی، تجویز همزمان آن با واکسن سه گانه و فلج اطفال عملی گردد.
متن کاملSimple sequence repeats in prokaryotic genomes.
Simple sequence repeats (SSRs) in DNA sequences are composed of tandem iterations of short oligonucleotides and may have functional and/or structural properties that distinguish them from general DNA sequences. They are variable in length because of slip-strand mutations and may also affect local structure of the DNA molecule or the encoded proteins. Long SSRs (LSSRs) are common in eukaryotes b...
متن کاملFirst Complete Genome Sequence of Haemophilus influenzae Serotype a
Haemophilus influenzae is an important human pathogen that primarily infects small children. In recent years, H. influenzae serotype a has emerged as a significant cause of invasive disease among indigenous populations. Here, we present the first complete whole-genome sequence of H. influenzae serotype a.
