Mutations at this same site confer SmR in Escherichia coli. 2019 Jul 25;11(1):45. doi: 10.1186/s13073-019-0660-8. The objectives of this study were to characterise mutations in rrs, rpsL and gidB genes in Mycobacterium tuberculosis isolates from Thailand and to examine possible associations between mutations and strain genotypes. Finken M, Kirschner P, Meier A, Wrede A, Böttger EC. DNA sequencing analysis, streptomycin (SM) resistance associated mutations in rpsL, rrs and gidB genes were examined in 101 Mycobacterium tuberculosis (MTB) clinical isolates with various lineages backgrounds from Thailand (46 SM resistant and 55 SM susceptible isolates). Streptomycin resistance in both gram-positive and gram-negative bacteria is usually caused by a single mutation in the rpsL gene. A 1.3-kb cassette was constructed comprising a kanamycin (Kn) resistance marker ( kan ) and a counterselectable rpsL +marker. HHS eCollection 2020 Nov. World J Microbiol Biotechnol. Streptomycin-resistant mutants Sm6 and Sm13, transformed with a plasmid carrying wt rpsL, pRpsL-wt (A), or rpsL having multiple silent mutations, pRpsL-sil (B), become more sensitive to streptomycin than mutants transformed with a plasmid carrying a mock gene, pRpsLΔ4. rapid detection of drug resistance against isoniazid, rifampicin, amikacin, capreomycin, streptomycin and fluoroquinolones in Mycobacterium tuberculosis. Other molecular mechanisms, such as reduced cell permeability to aminoglycosides or presence of drug-modifying enzymes, might contribute to its streptomycin resistance. A prerequisite for this system is acquiring a streptomycin-resistant strain due to rpsL mutations, which encodes the ribosomal protein S12. We amplified, sequenced and compared the rpsL gene of the wild‐type and kan r strains. Dr. Mohammad Arjomandzadegan The presence of the aadE gene encoding aminoglycoside 6-adenylyltransferase was also evaluated. In this report, we have examined the mechanism of resistance to streptomycin (Sm) in M. tuberculosis through the cloning and nucleotide sequence analysis of the gene encoding the ribosomal S R protein (rpsL gene) from streptomycin‐resistant strains and their streptomycin‐sensitive parental strains. Streptomycin (SM) is one of the most effective drugs for the treatment of multidrug-resistant (MDR) tuberculosis. The rpsL gene and streptomycin resistance in single and multiple drug‐resistant strains of Mycobacterium tuberculosis Jaygopal Nair Laboratory of Mycobacteria, Center for Biologics Evaluation and Research, United States Food and Drug Administration, 8800 … The rpsL genes of various bacteria have consensus regions in their sequences. Frequencies of streptomycin-resistance associated rpsL and rrs mutations in 86 Mycobacterium tuberculosis Beijing and non-Beijing strains with acquired resistance Beijing Non-Beijing rpsL codon 43 mutation 58 (88) 8 (40) rpsL codon 88 mutations 3 (4.5) 7 (35) rrs mutations 2 (3) 3 (15) Wild type 3 (4.5) 2 (10) Total 66 (100) 20 (100) 2. The hot mutation sites in H. parasuis also indicates that the K → R mutations in 43rd and 88th codons in rpsL, which encodes the highly conserved RpsL protein of the ribosomal accuracy centre (Toivonen, Boocock & Jacobs, 1999), have a greater propensity to confer drug resistance to streptomycin than rrs and other mutation sites. 6 Mutations associated with streptomycin resistance in Mycobacterium tuberculosis have been identified in the rpsL and rrs genes, which encode the ribosomal protein S12 and 16S rRNA, respectively. C onclusions: Streptomycin resistance is mainly related to mutation at codons 43 and 88 "rpsL" gene and to a lesser extent "rrs" that are the greatest cause of drug resistance to streptomycin. The presence of the aadE gene encoding aminoglycoside 6-adenylyltransferase was also evaluated. Copyright © 2021 Elsevier B.V. or its licensors or contributors. The cassette conferred dominant streptomycin (Sm) sensitivity in an Sm-resistant background in S. pneumoniae . Susceptibility tests were carried out using the fluorometric method, and rrs and rpsL DNA sequencing was performed by capillary electrophoresis. In contrast, two other multiple drug-resistant M. tuberculosis strains that are resistant to Sm have rpsL genes that have the same nucleotide sequence as their drug-sensitive parent strains, suggesting that different resistance mechanisms are involved in these strains. Genotypes of the isolates were identified … Erwinia amylovora can rapidly become highly resistant to applications of the antibiotic streptomycin through a single nucleotide mutation in the rpsL gene, which causes an amino acid substitution that prevents inhibitory binding of streptomycin while preserving the functionality of the ribosome.

However, resistance to SM is increasingly reported mainly due to mutations in rpsL … Molecular mechanisms of multiple drug resistance in clinical isolates of Mycobacterium tuberculosis. Streptomycin resistance frequently results from a mutation in the open reading frame of rpsL (Ochi et al. Surprisingly, in media with poorer carbon sources, the same Str R mutants grow faster than wild type. Recall that certain mutations in the rpsl gene of Bacteria can lead to streptomycin-resistance. The strB gene, encoding an aminoglycoside 6‐phosphotransferase that inactivates streptomycin, was detected in all Chilean strains, including sensitive and resistant strains. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. The rpsL gene encodes the S12 protein of the ribosomal complex. Streptomycin-resistant mutants Sm6 and Sm13, transformed with a plasmid carrying wt rpsL, pRpsL-wt (A), or rpsL having multiple silent mutations, pRpsL-sil (B), become more sensitive to streptomycin than mutants transformed with a plasmid carrying a mock gene, pRpsLΔ4. Wepreviously reported that certain mutations in rpsL (encoding the ribosomal S12 protein) not only confer resistance to streptomycin but also activate the production of secondary metabolites (antibiotic production) in various bacteria10'11\ Wewere interested in determining whether aminoglycoside antibiotics other than streptomycin exert Here we investigated the fitness effects of three different streptomycin resistance mutations K42N, K42R, and P90S, all located in ribosomal protein S12 encoded by the rpsL gene.

The mutation pattern and frequency related to SM resistance  |  It is shown here that streptomycin resistance in some clinical isolates of Mycobacterium tuberculosis is associated either with missense mutations in the rpsL … In conclusion, the streptomycin resistance caused by rpsL the highest frequency in streptomycin-resistant clinical isolates of mutations usually made the bacteria less competitive than its wild- Mycobacterium tuberculosis, while the K87R mutant was also type strain in the absence of … Most of the STR-resistant isolates (80.9%) carried putative resistance-associated mutations in the analysed genes. Resistance to streptomycin is mainly associated with two genes: rpsL and rrs. Molecular basis of streptomycin resistance in Mycobacterium tuberculosis: alterations of the ribosomal protein S12 gene and point mutations within a functional 16S ribosomal RNA pseudoknot. However, resistance to SM is increasingly reported mainly due to mutations in rpsL and rrs genes. [Google Scholar] Ohama T, Yamao F, Muto A, Osawa S. Organization and codon usage of the streptomycin operon in Micrococcus luteus, a bacterium with a high genomic G + C content. Nat Commun. The variety and presence or absence of the mutations found suggest the circulation of an important diversity of strains and the existence of additional mechanisms contributing to streptomycin resistance in the region. rpsL carried by plasmids efficiently sensitizes streptomycin-resistant mutants. Mutations in rpsL were observed in 18 isolates (19%) in codons 43 (A→G, K/R, n = 12) and 88 (A→G, K/R, n = 4; A→C, K/Q, n = 2). In total, 110 streptomycin (STR)-resistant M. tuberculosis isolates and 51 STR-susceptible isolates obtained from a sample collection in Thailand during 1999-2011 were sequenced for mutation analysis in rrs, rpsL and gidB. 2. Mycobacteria were isolated from patients with suspected drug-resistant tuberculosis. 6 Mutations associated with streptomycin resistance in Mycobacterium tuberculosis have been identified in the rpsL and rrs genes, which encode the ribosomal protein S12 and 16S rRNA, respectively. The rpsL genes of various bacteria have consensus regions in their sequences. A strain of Streptomyces lividans, TK24, was found to produce a pigmented antibiotic, actinorhodin, although S. lividans normally does not produce this antibiotic. 2019 Oct 22;35(11):165. doi: 10.1007/s11274-019-2749-z. We have demonstrated that five singly SmR M. tuberculosis strains and an SmR isolate that has reduced sensitivity to multiple antibiotics have identical point mutations at codon 43 of the rpsL gene. COVID-19 is an emerging, rapidly evolving situation. Copyright © 2012 Published by Elsevier Taiwan LLC. In this report, we have examined the mechanism of resistance to streptomycin (Sm) in M. tuberculosis through the cloning and nucleotide sequence analysis of the gene encoding the ribosomal S12 protein (rpsL gene) from streptomycin-resistant strains and their streptomycin-sensitive parental strains.

Molecular genetic basis of antimicrobial agent resistance in Mycobacterium tuberculosis: 1998 update. 1996 ). (PMID 7968530) Resistomes. Antimicrob Agents Chemother. However, in this study no streptomycin resistance was found to be caused by rpsL mutations in all 127 clinical strains of Klebsiella pneumoniae isolated … Recently, the gidB gene was found to be associated with low-level streptomycin resistance in Mycobacterium tuberculosis. Streptomycin resistance frequently results from a mutation in the open reading frame of rpsL (Ochi et al. The goal of this study was to characterize these mutations in isolates of streptomycin-resistant mycobacteria originating from southeast Mexico. Cohen KA, Manson AL, Desjardins CA, Abeel T, Earl AM. Mutation K43R in rpsL was strongly associated with high-level streptomycin resistance (P < 0.01), while mutations in rrs and gidB potentially contributed to low-level resistance (P < 0.05).

Streptomycin acts on the ribosome, inhibiting the translation of mRNA and thereby disrupting protein synthesis. Streptomycin, the first antibiotic used in tuberculosis control programs, perturbs protein synthesis at the ribosome level. The K42N and P90S mutations increase the accuracy of translation, leading to a consequential reduction in translation rate and thereby reduced fitness in rich medium and in mice ( K urland et al. Interestingly, the four streptomycin‐sensitive … Genome shuffling for improving the activity of alkaline pectinase in Bacillus subtilis FS105 and its molecular mechanism. 2018 Oct 17;9(1):4306. doi: 10.1038/s41467-018-06634-y. The recent emergence of indolent and rapidly fatal drug-resistant strains of Mycobacterium tuberculosis has renewed interest in defining the molecular mechanisms of drug resistance in the tubercle bacilli. 1998;79(1):3-29. doi: 10.1054/tuld.1998.0002. Beijing strains were related not only to single resistance-associated mutations in rpsL or rrs but usually harboured a second mutation in gidB. Two genes (rpsL and rrs) with mutations associated with streptomycin resistance in Mycobacterium tuberculosis were characterized in 78 streptomycin-resistant and 61 streptomycin-susceptible isolates recovered from patients living in the United States, South America, Europe, Africa, and Asia. 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 Mutations in rrs were observed in 26 isolates (28%). Read 1 answer by scientists to the question asked by Merijn L M Salverda on Feb 13, 2020 6,7,8,9 Recent studies have also shown that low-level streptomycin resistance (MIC ≥ 10 mg/L) is determined by different genes from high-level streptomycin resistance (MIC ≥ 160 mg/L). Currently, mutations in three genes, namely rrs, rpsL, and gidB, encoding 16S rRNA, ribosomal protein S12, and 16S rRNA-specific methyltransferase, respectively, are considered to be involved in conferring resistance to streptomycin (STR) in Mycobacterium tuberculosis. See Help:Gene_nomenclaturefor help with entering information in the Gene Nomenclature table. Incidence of resistance is increasingly reported. Mol Microbiol. Point mutations in rpsL, the gene encoding S12, have been identified as the key factor conferring streptomycin resistance and at the same time activate the expression of cryptic antibiotics, like the blue-colored actinorodhin (40, 41). Mutations therefore genetically alter the number of rpsL and rrs alleles contained in the bacterial genome. To characterize the mechanisms of streptomycin (STR) resistance in Campylobacter coli, we chose 17 isolates that were resistant to STR, erythromycin (ERY), or both, and the putative STR resistance target genes rpsL, rrs, and gidB were analyzed for mutations. Some 136 drug-resistant isolates were recovered, of which 91(67%) exhibited resistance to streptomycin. The streptomycin resistance (Str R) mutations K42N and P90S in ribosomal protein S12 impair growth on rich medium. Recently, the gidB gene was found to be associated with low-level streptomycin resistance in Mycobacterium tuberculosis. This site needs JavaScript to work properly. Would you like email updates of new search results? From literature, 25–52% of streptomycin-resistant MTB isolates harbored wildtype rpsL and rrs genes [23,24,25]. In addition to rpsL, the rrs gene (which encodes 16S ribosomal RNA) has been implicated in streptomycin resistance with a frequency of about 10%. Mechanisms of drug-resistance in Mycobacterium tuberculosis--genetic mechanisms of drug-resistance]. Key words: Mycobacterium tuberculosis, Streptomycin, drug resistance, rpsL gene, rrs gene. 2004).

Sci Rep. 2019 Jul 16;9(1):10283. doi: 10.1038/s41598-019-46756-x. Streptomycin inhibits protein synthesis by binding to the small ribosomal subunit. In summary, most of the K. pneumoniae strains with streptomycin resistance caused by rpsL mutations are less virulent than their parental strain in the absence of streptomycin. 1993 Nov; 10 (3):521–527. This means that mutations in the RRs conferring streptomycin resistance could be selected and isolated altering the coding of the gene, protein, and cell structure involved. Background/PurposeMutations in rpsL and rrs genes are associated with resistance to streptomycin in tuberculosis, but important geographical variation exists in these mutations. In the 21 resistant strains, a mutation in codon 43 of the rpsL gene was determined, conferring high streptomycin resistance. 1995 Apr;171(4):954-60. doi: 10.1093/infdis/171.4.954. Point mutations in streptomycin resistant isolates have been reported in rpsL genes in 65–67% of STR resistant isolates (Ramaswamy et al.,1998).Mutations in the rpsL gene at codon 43 (AAG-AGG/ACG) (Lys-Arg/Thr) and codon 88 (AAGAGG/CAG) (Lys-Arg/Gln) are associated with streptomycin resistance. Streptomycin resistance in both gram-positive and gram-negative bacteria is usually caused by a single mutation in the rpsL gene. Mutations related to streptomycin resistance in the rpsL and rrs genes are well known and can explain about 70% of this phenotypic resistance. Other molecular mechanisms, such as reduced cell permeability to aminoglycosides or presence of drug-modifying enzymes, might contribute to its streptomycin resistance. However, resistance to SM is increasingly reported, mainly due to mutations in the rpsL and rrs genes. rpsL in streptomycin resistant M. tuberculosis strains.The purpose of the study described here was (i) to characterize the level of resistance associated with the different molecular mechanisms and (ii) to investigate whether a permeability barrier contributes to drug resistance in streptomycin resistant isolates with wild-type rpsL.
