antibiotic resistance genes

During the past few Fridays (or least here and here), we've been looking at a paper that was published from China with some Β-lactamase sequences that were supposedly from Streptococcus pneumoniae. The amazing thing about these particular sequences is that Β-lactamase has never been seen in S. pneumoniae before, making this a rather significant (and possibly scary) discovery. If it's correct. tags: DNA sequence analysis, antiobiotic resistance , microbiology, blastn The way this sequence was identified as Β-lactamase was through a blastn search at the NCBI. And in fact, it was correct to…
