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 ...

Should treatment of low-level rifampicin mono-resistant tuberculosis be different?

Journal of Clinical Tuberculosis and Other Mycobacterial Diseases, 2021
Background: Rifampicin resistant tuberculosis (RR-TB) was frequently detected in Suriname after the introduction of Xpert MTB/RIF in 2012. Subsequent phenotypic drug-susceptibility testing (DST) was not conclusive at that moment, while RR-TB patients ...

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.

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.

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.

Resistance of Mycobacterium tuberculosis strains to Rifampicin: A systematic review and meta-analysis

Heliyon, 2019
Introduction: Antitubercular drug resistance strain is a horrifying barrier to effective TB treatment and prevention. The present study aimed to determine the prevalence and geographical distribution of rifampicin-resistance M. tuberculosis (MTB) strains.

Rifampicin impregnated dacron grafts: No development of rifampicin resistance in an animal model

European Journal of Vascular and Endovascular Surgery, 1995
Rifampicin impregnated Dacron grafts have been shown to be effective at preventing vascular graft infection in different animal models. The development of resistance to rifampicin would be a major drawback to the widespread use of such a graft. We aimed to determine how readily this would occur by using a sheep animal model.Under general anaesthetic a ...

Clinical perspectives on treatment of rifampicin-resistant/multidrug-resistant TB [PDF]

The International Journal of Tuberculosis and Lung Disease, 2020
Rapid diagnostics, newer drugs, repurposed medications, and shorter regimens have radically altered the landscape for treating rifampicin-resistant TB (RR-TB) and multidrug-resistant TB (MDR-TB). There are multiple ongoing clinical trials aiming to build a robust evidence base to guide RR/MDR-TB treatment, and both observational studies and ...
