PLoS ONE, 2020 BackgroundPakistan is among top five high burden countries for tuberculosis and drug resistant TB. Among rifampicin sensitive new pulmonary TB (PTB), prevalence of isoniazid resistance is 8.3% (95%CI: 7.0-10.7) and resistance to fluoroquinolone is higher

Microbiology Spectrum, 2022 Due to increasing rates of antimicrobial resistance (AMR) in Neisseria gonorrhoeae, alternative treatments should be considered. To assess rifampicin’s potential as a gonorrhea treatment, we used rpoB mutations to estimate rifampicin resistance in ...

Genetic Transformation of Rifampicin Resistance in Lactobacillus acidophilus [PDF]
Microbiology, 1986 Lactobacillus acidophilus strain 100-33, originally isolated from swine faeces, was transformed to rifampicin resistance with DNA from spontaneous rifampicin-resistant mutants derived from it. Cells of the recipient strain were treated with lysozyme and mutanolysin, mixed with donor DNA and polyethylene glycol and grown on a regeneration medium ...

Diagnosis of rifampicin-resistant tuberculosis: Discordant results by diagnostic methods
African Journal of Laboratory Medicine, 2018 The performance of the Xpert© MTB/RIF and MTBDRplus assays for the detection of rifampicin resistant Mycobacterium tuberculosis was compared to culture-based drug susceptibility testing in 30 specimens with rifampicin-resistant and rifampicin ...

Chylothorax in a child with rifampicin-resistant tuberculosis
African Journal of Thoracic and Critical Care Medicine, 2019 Chylothorax is rare in children. Only a few cases of tuberculosis (TB)-associated chylothorax have been reported. We present a child on standard four-drug TB treatment who presented with wheezing and a chylothorax. Bronchoscopy showed caseating lymph nodes, and rifampicin-resistant TB was identified from the bronchoalveolar lavage specimen.

Daptomycin-reversible rifampicin resistance in vancomycin-resistant Enterococcus faecium [PDF]
Journal of Antimicrobial Chemotherapy, 2007 In a previous study, we observed marked synergy between daptomycin and rifampicin against 73% of rifampicin-resistant, vancomycin-resistant Enterococcus faecium (VRE), with approximately 100-fold reductions in rifampicin MICs observed at one-eighth to one-fourth daptomycin MIC.

rpoB mutations and their association with rifampicin resistance in clinical Staphylococcus epidermidis. [PDF]
J Antimicrob ChemotherBackground: Staphylococcus epidermidis is a ubiquitous member of the healthy skin and mucous microbiota but is also an opportunistic pathogen responsible for various infections, often treated with antibiotics like rifampicin.

Virulence of Rifampicin-Resistant Mutants of Bacteria
Nippon Saikingaku Zasshi, 1971 1. ネズミチフス菌LT-2株および黄色ブドウ球菌209P株で,rifampicin (RFP)耐性の上昇は,ストレプトマイシン型を示した。2. ネズミチフス菌LT-2株におけるone-step RFP高度耐性菌の出現頻度は約10-8,黄色ブドウ球菌209P株では約10-7であつた。3. LT-2株に紫外線を照射するとRFP高度耐性菌の出現頻度は高くなるが,形質発現にかなりの時間を要するので,劣性変異と考えられる。4. LT-2株,209P株ともに,one-step RFP高度耐性菌は比較的高頻度にRFP耐性を失う。5.
