Scientists have become increasingly concerned about the occurrence of antibacterial resistance in the environment. In this study, Escherichia coli resistant to one or more antibiotics among nine antibiotics was screened from Wenyu River Basin in Beijing, China, with mean frequency of 48.7 +/- 8.7% of 388 isolates in summer and 47 +/- 6% of 236 isolates in winter. The mean multiantibiotic resist...

In this paper I propose an scenario for the top quark as a topological color soliton. I illustrate some features of the top quark as a soliton in a toy model based on nonlinear realization of the SUL(3) × SUR(3)/SUL+R(3) with SUL+R(3) being the color gauge group.

Deoxyribonucleate (DNA) preparations were extracted from Neisseria meningitidis (four isolates from spinal fluid and blood) and N. gonorrhoeae strains, all of which were resistant to sulfadiazine upon primary isolation. These DNA preparations, together with others from in vitro mutants of N. meningitidis and N. perflava, were examined in transformation tests by using as recipient a drug-suscept...

Stenotrophomonas maltophilia is a common nosocomial pathogen that causes high morbidity and mortality. Because of its inherent extended antibiotic resistance, therapeutic options for S. maltophilia are limited, and sulfamethoxazole/trimethoprim (SXT) is the only first-line antimicrobial recommended. However, with the spread of dihydropteroate synthase (sul1 and sul2) genes, global emergence of ...

Pediatra, Mestre em Pediatria pela Universidade Federal do Rio Grande do Sul. A atividade da lactase é determinada por um gene localizado no cromossomo 2 e a sua atividade na vida adulta tem herança autossômica dominante, enquanto a hipolactasia é herdada de forma auto...

A new simple, rapid and sensitive reversed-phase liquid chromatographic method was developed and validated for the simultaneous determination of sulpiride (SUL) and mebeverine Hydrochloride (MEB) in the presence of their impurities and degradation products. The separation of these compounds was achieved within 6 min on a 250 mm, 4.6 mm i.d., 5 m particle size Waters®-C18 column using isocractic...

We evaluated the effect of several compounds on their ability to reduce the production of sul®de in in vitro ruminal fermentations, when sulfur content of the diet was 1% (dry matter basis). Excess sulfur increased (p<0.05) ruminal sul®de production, but had no effects on VFA production. The effect of 1, 10 and 25 ppm ( ̄uid basis) of 9,10 anthraquinone (AQ) and molybdenum in high sulfur diets w...

The presence of Mycobacterium bovis in bovine carcasses with lesions suggestive of tuberculosis was evaluated. Seventy-two carcass samples were selected during slaughter inspection procedures in abattoirs in the state of Mato Grosso do Sul, Brazil. Seventeen (23.6%) of samples showed colonies suggestive of mycobacteria that were confirmed to be acid-fast bacilli by Ziehl-Neelsen staining. Polym...
