Preparing Bacterial Genomic DNA

Cold Spring Harbor Protocols, 2022
We describe two alternative procedures for purifying bacterial chromosomal DNA. The first procedure incorporates the use of a commercial kit based on silica membrane technology. This approach relies on the selective binding of DNA to a silica-based column in the presence of chaotropic salts (guanidine salts).

Chloramphenicol damages bacterial DNA

Biochemical and Biophysical Research Communications, 1977
L(+)-threo-chloramphenicol induces reversion of His−Salmonella typhimurium strains TA100 and TA1535 in the conventional Ames' assay without microsomal activation. Any mutagenicity of D(−)-threo-chloramphenicol was masked by toxicity. Similarly, a sensitive fluctuation test showed mutagenesis with L(+)-threo-chloramphenicol at concentrations of 0.5 μM ...

Bacterial DNA excision repair pathways

Nature Reviews Microbiology, 2022
Bacteria are continuously exposed to numerous endogenous and exogenous DNA-damaging agents. To maintain genome integrity and ensure cell survival, bacteria have evolved several DNA repair pathways to correct different types of DNA damage and non-canonical bases, including strand breaks, nucleotide modifications, cross-links, mismatches and ...

Comparing Bacterial DNA Microarray Fingerprints

Statistical Applications in Genetics and Molecular Biology, 2005
Epidemiologic and forensic investigations often require assays to detect subtle genetic differences between closely related microorganisms. Typically, gel electrophoresis is used to compare randomly amplified DNA fragments between microbial samples, where the patterns of DNA fragment sizes are viewed as genotype ‘fingerprints’.
