conclusions the results showed that e. coli isolated from patients with uti had eight virulence factors with high frequencies. moreover, these results alleged a direct connection between virulence factors and antimicrobial resistance in e. coli. results the frequency of virulence factors papc, afa, sfa/foc, fimh, hly, neuc, ibea, and iucc were 53.3%, 51.7%, 53.3%, 56.7%, 23.3%, 31.7%, 20%, and ...

In this paper, we revisit the disorder–order transition in 1-chloro-adamantane and present new data on 1-bromo-adamantane. Rayleigh scattering Raman-active optical lattice phonons are used to easily characterize phase change. Unlike Cl-derivative, Br-derivative shows a semiordered structure vicinity of ambient P,T conditions, which is peculiar compound seems be due more reduced rotational disor...

The Mo(CO)6-mediated photoinduced ring-opening reactions of adamantane isoxazolines involve novel rearrangement that provide enaminoketones as major products and b-hydroxy ketones as minor ones; in contrast, only b-hydroxy ketones and a,b-unsaturated ketones were obtained under thermal condition. 2006 Elsevier Ltd.

The title adamantane derivative, C(19)H(25)NO(2), was synthesized as part of a study into potential anti-tuberculosis agents. The adamantane skeleton displays shorter than normal C-C bond lengths ranging between 1.5230 (15) and 1.5329 (16) Å. The structure displays O-H⋯O hydrogen bonding and an inter-digitated layered packing structure with distinct hydro-philic and hydro-phobic regions.

The stability,optimized structure,binding energy,dipole moment and electronic gap of adamantane, C10H16,incorporating cage-centered small atoms and ions (X@cage, where X = Li, Be, Na, Mg, He, and Ne) have been studied at the B3LYP hybrid level of theory. A wide variety of atoms and ions can be encapsulated by adamantane. The complexes are more stable for smaller and more highly charged metallic...

background : multi drug-resistant mycobacterium tuberculosis (mdr-tb) is an infection with a causative bacillus which is resistant to at least two drugs, isoniazid and rifampin. the purpose of this study is to evaluate the prevalence of tb resistance to first-line drugs of newly diagnosed active pulmonary tuberculosis. methods : this cross-sectional study was performed on 77 patients with newly...

background pseudomonas aeruginosa is an opportunistic pathogen mostly affecting hospitalized and immunodeficient patients. considering the extent of attention paid to the issue of antibiotic resistance and the origin of such resistance and the growing number of treatment failures in patients with burn injury, it seems that investigating the degree of ampc gene expression could be beneficial for...

conclusions findings of this study showed that integron can have a limited frequency in s. aureus isolated from clinical sample in tehran. results among the 200 samples, 1% of the strains (two isolates) contained the class 1 integron gene. the results of this study showed that the highest frequency of the obtained samples belonged to males and the isolates occurred mostly in individuals aged 51...

bacteremia is an important infectious disease which may lead to death. common bacteria and pattern of antibiotic resistance in different communities are different and understanding these differences is important. in the present study, relative frequency and pattern of drug resistance have been examined in bacteria isolated from blood cultures in razi hospital laboratory. the method of the study...
