Introduction Paromomycin1•`4) and aminosidineo are aminoglucoside antibiotics recently discovered. Identity of paromomycin and aminosidine has been reportedo. Knowledge of cross-resistance-relationships in respect to this antibiotic is very scanty. ARCAMONE et al. 5) stated that a neomycin-resistant strain of Staphylococcus aureus was resistant to paromomycin. The present study was carried out ...

The Zuotin-family J protein chaperone GlsA is essential for the asymmetric divisions that establish germ and somatic cell initials during embryogenesis in the green alga Volvox carteri, but it is not known on what cellular process GlsA acts to carry out this function. Most GlsA protein is nuclear, and GlsA possesses two SANT domains, suggesting that GlsA may function as a transcriptional regula...

UNLABELLED The emerging epidemic of drug resistance places the development of efficacious and safe antibiotics in the spotlight of current research. Here, we report the design of next-generation aminoglycosides. Discovery efforts were driven by rational synthesis focusing on 4' alkylations of the aminoglycoside paromomycin, with the goal to alleviate the most severe and disabling side effect of...

Translational leakiness (i.e., nonspecific suppression) of nonsense mutants of bacteriophage T4 is increased in cells of certain streptomycin-resistant strains previously grown in the presence of streptomycin. Concomitantly, ribosomes extracted from these streptomycin-grown cells possess a high level of misreading. Increased suppression ability as well as ribosomes that highly misread accumulat...

OBJECTIVE To compare the parasitological and clinical efficacy of four weeks versus two weeks of treatment with aminosidine (paromomycin) ointment in patients with cutaneous leishmaniasis caused by Leishmania major in the Islamic Republic of Iran. METHODS Double-blind, randomized trial of four weeks of aminosidine ointment (n = 108) vs two weeks of aminosidine ointment and two weeks of placeb...

The aminoglycoside antibiotics target a region of highly conserved nucleotides in the aminoacyl-tRNA site (A site) of 16 S RNA on the 30 S subunit. The structures of a prokaryotic decoding region A-site oligonucleotide free in solution and bound to the aminoglycosides paromomycin and gentamicin C1A have been determined. Here, the structure of a eukaryotic decoding region A-site oligonucleotide ...

Dientamoeba fragilis is a commonly encountered trichomonad which has been implicated as a cause of gastrointestinal disease in humans. Despite the frequency of reports recording infections with this parasite, little research has been undertaken in terms of antimicrobial susceptibility. The aim of this study was to evaluate the susceptibility of D. fragilis to several commonly used antiparasitic...

6-methylpurine (6mp) is a toxic analog of adenine that inhibits RNA and protein synthesis and interferes with adenine salvage mediated by adenine phosphoribosyltransferase (APRTase). Mutants of the ciliated protist Tetrahymena thermophila that are resistant to 6mp were isolated in 1974, but the mechanism of resistance has remained unknown. To investigate 6mp resistance in T. thermophila, we cre...

The genetic transformation of monocot grasses is a resource intensive process, the quality and efficiency of which is dependent in part upon the method of DNA introduction, as well as the ability to effectively separate transformed from wildtype tissue. Agrobacterium-mediated transformation of Brachypodium has relied mainly on Agrobacterium tumefaciens strain AGL1. Currently the antibiotic hygr...
