Detection of A2142C, A2142G, and A2143G Mutations in 23s rRNA Gene Conferring Resistance to Clarithromycin among Helicobacter pylori Isolates in Kerman, Iran [PDF]

Iranian Journal of Medical Sciences, 2011
Background: Clarithromycin resistance in Helicbacter pylori has been found to be associated with point mutations in 23s rRNA gene leads to reduced affinity of the antibiotic to its ribosomal target or changing the site of methylation.

Selection of Resistance to Clarithromycin in Mycobacterium abscessus Subspecies [PDF]

Antimicrobial Agents and Chemotherapy, 2017
ABSTRACT Mycobacterium abscessus is an emerging pathogen against which clarithromycin is the main drug used. Clinical failures are commonly observed and were first attributed to acquired mutations in rrl encoding 23S rRNA but were then attributed to the intrinsic production of the ...

Lack of association between rrl and erm(41) mutations and clarithromycin resistance in Mycobacterium abscessus complex

Memorias do Instituto Oswaldo Cruz
BACKGROUND Mycobacterium abscessus complex (MABC) includes species with high resistance rates among mycobacterial pathogens. In fact, MABC infections may not respond to clarithromycin treatment, which has historically been very effective against MABC ...
