streptomycin resistance plasmid

These results suggest that another mechanism of streptomycin resistance was work-ing in addition to the direct usage of streptomycin. Plasmid-mediated high-level resistance to multiple antibiotics was reported in a clinical isolate of Yersinia pestis in Madagascar in 1997. So, what antibiotic concentration of Streptomycin … h�bbd``b`Z$��F ��H� �l ��HHOs��v�30R��ϸ�@� �� The streptomycin resistance genes in pIP1203 are part of the tnpR-strA-strB-IR cluster characteristic of the Tn5393 group of transposons. papulans, and Xanthomonas campestris pv.

Inventors: TOBA ... Amsterdam T. HASHIMOTO-GOTOH et al. Transfer occurred at high frequencies (3 x 10-1 per donor CFU) to Y. pestis (MIC = 1,024 mg/L) and Y. pseudotuberculosis (MIC = 256 mg/L) and at lower frequencies to E. coli (MIC = 128 mg/L); transfer to Y. enterocolitica was not detected. Her research interests are bacterial pathogenesis and antibiotic resistance. The size of the molecular weight markers in kilobases is indicated at the left of the gels. The subclone DNA hybridized with enzyme-digested genomic or plasmid DNA of three of 17 other resistant strains of X. c. vesicatoria as well as with the DNA from streptomycin-resistant strains Psp 34 and Psp 36 of Pseudomonas syringae pv. Analysis of plasmid pIP1203. These factors cannot get inserted into the bacterial chromosome. The plasmid has a copy number of about 25 per cell, and PBP1, which in addition mediates sulfonamide resistance, has been found to be disseminated in … Low-level resistance was usually indicative of small multicopy RC plasmids, such as pS194, which carries the streptomycin adenyltransferase-encoding gene str. This enzyme is encoded by the plasmid pBP1 in 80 % of all streptomycin resistant strains tested. %PDF-1.6 %���� The resistance determinant was subcloned by introducing a 2.7-kb HincII fragment of the 11-kb insert into pUC18, which generated pAT710. %%EOF Viva la (bacterial) resistance!

Upstream from strA, the sequence was identical to a portion of the tnpR resolvase-repressor gene of Tn5393, Tn5393a, and Tn5393b[20]. Attempts were made to transfer streptomycin resistance from Y. pestis 16/95 by conjugation to recipient strains (MIC ≤ 8 mg/L) (Table 2). 51 0 obj <>/Filter/FlateDecode/ID[<7C53C2982149824D9FD52FBF894999EC><7E8764B98FC8E249953CB5AA8699AABB>]/Index[42 28]/Info 41 0 R/Length 65/Prev 103505/Root 43 0 R/Size 70/Type/XRef/W[1 2 1]>>stream Several plasmids from Staph. 2). Figure 2. No incompatibility with prototype plasmids of incompatibility groups Inc FI, FII, I1, I2, N, 6-C, 7-M, 10-B-O, J, T, and W was observed[15]. Abstract. From this streptomycin-sensitive plasmid vector recombinant molecules can thus be directly selected. These results suggest that pCK41 is a virulence plasmid of substantial importance in the E. tarda pathogenesis to fish. Adding an antibiotic resistance gene to the plasmid solves both problems at once – it allows a scientist to easily detect plasmid-containing bacteria when the cells are grown on selective media, and provides those bacteria with a pressure to keep your plasmid. In experiments performed by reciprocal conjugation to assess the incompatibility group, pIP1203 exhibited strong incompatibility with plasmid RP4 (data not shown), which belongs to the IncP group. Like Tn5393a, pIP1203 possessed the TAG motif, which represents a putative insertion target for IS1133[20]. Genetic organization of the strA-strB genes.

Hence you need to know exactly what spectinomycin resistance gene your plasmid carries if you want to replace spectinomycin with the cheaper streptomycin. Meaning of Resistance Plasmid: Resistance factors or resistance plasmids are a group of conjugative plasmids which confer to their bacterial host resistance to specific antibiotics, such as, chloramphenicol, sulphonamide, streptomycin, tetracycline etc., and to several metal ions, e.g., Hg, As, Cd etc. Figure 1. Plasmids associated with resistance to streptomycin, to streptomycin plus chloramphenicol or to tetracycline in Staphylococcus hyicus isolated from the skin of pigs have been compared, by restriction endonuclease digest patterns, with similar staphylococci from human sources and with published DNA base sequences. A streptomycin-resistant Listeria monocytogenes LM35 harbouring a 54 kilobase plasmid and three small plasmids of 2.7, 2.8 and 3.0 kilobase in sizes (donor strain, see Figure 1), and streptomycin-sensitive and plasmidless L. monocytogenes LM65 and LM100 (recipient strains) isolated from imported frozen beef used in this study have been described previously .
