The conjunctivitis produced by Neisseria gonorrhoeae is the less frequently reported clinical form of gonococcal infection. We aim to phenotypically characterize N. gonorrhoeae isolated from conjunctivae sites. A total of six cases of this disease were notified in the Camagüey province, Cuba. All the strains isolated were penicillin-producing, showed the serogroup WI and exhibited the same anti...
In this report, we present cationic dimeric (gemini) lipids for significant plasmid DNA (pDNA) delivery to different cell lines without any marked toxicity in the presence of serum. Six gemini lipids based on α-tocopherol were synthesized, which differed in their spacer chain lengths. Each of these gemini lipids mixed with a helper lipid, 1,2-dioleoyl phosphatidyl ethanolamine (DOPE), was capab...
CTX-M-131 is a natural Asp240Gly variant from the CTX-M-2 group detected in a Providencia rettgeri clinical strain from Brazil. Molecular analysis showed that blaCTX-M-131 was inserted in a complex class 1 integron harbored by a 112-kb plasmid, which has not been previously described as a platform for CTX-M-encoding genes with the Asp240Gly mutation. Steady-state kinetic parameters showed that ...
BACKGROUND Today, significant increase in the prevalence and emergence of methicillin-resistant Staphylococcus aureus (MRSA) is a serious public health concern and is likely to have a dramatic negative impact on many current medical practices. Therefore, identification of MRSA strains is important for both clinical and epidemiological implications. OBJECTIVES The present study was carried out...
BACKGROUND & OBJECTIVES The multiple drug resistance (MDR) is a serious health problem and major challenge to the global drug discovery programmes. Most of the genetic determinants that confer resistance to antibiotics are located on R-plasmids in bacteria. The present investigation was undertaken to investigate the ability of organic extract of the fruits of Helicteres isora to cure R-plasmids...
Nonpolar virB mutants of Agrobacterium tumefaciens were tested for RSF1010 mobilization and extracellular complementation. virB2 to virB11 were essential for transfer in both assays. virB1 was essential only for high frequency transfer of RSF1010 and VirE2. Coordinated transfer of a preassembled T complex is supported by these data and competition studies.
Background Carbapenemase-producing Enterobacteriaceae (CPE), including KPC-producing Klebsiella pneumoniae (KPC-Kpn), are an increasing threat to patient safety. Objectives To use WGS to investigate the extent and complexity of carbapenemase gene dissemination in a controlled KPC outbreak. Materials and methods Enterobacteriaceae with reduced ertapenem susceptibility recovered from rectal s...
the aim of the study was to determine the resistance patterns of pseudomonas aeruginosa isolates recovered from patients with surgical wounds in hospitals and also to investigate their epidemiological relatedness using molecular typing techniques. twenty pseudomonas sp. isolated from surgical wounds were subjected to antibiotic susceptibility testing by disk diffusion, plasmid profile, sds-page...
a total of twenty seven bacterial strains were isolated from cankerous tissues of apricot, nectarine, peach, plum, sour cherry and sweet cherry trees in tehran province and identified as pseudomonas syringae pv. syringae (pss), the causal agent of the bacterial canker disease, on the basis of lopat (levan production, oxidase test, potato rot, arginine dihydrolase and tobacco hypersensitive ...
Cellular gene delivery via polycations has wide implications for the potential of therapy, but it remained a challenge due to plethora pre- and post-uptake barriers that must be overcome reach desired efficiency. Herein we report poly(hexamethylene biguanide) (PHMB) as nano-vector intracellular plasmid DNA (pDNA) oligodeoxynucleotides (ODNs). PHMB pDNA or ODNs self-assembled into complex nanopa...
