The level of acid resistance among Escherichia coli O157:H7 strains varies, and strains with higher resistance to acid may have a lower infectious dose. The complete genome sequences belonging to two strains of Escherichia coli O157:H7 with different levels of acid resistance are presented here.
BACKGROUND Zoledronic acid is an important osteotropic compound used in combination with anticancer agents to reduce the incidence of hypercalcemia and skeletal morbidity in patients with advanced breast cancer and bone metastases. Ineffectiveness of anticancer drugs during chemotherapy is a frequently observed situation in cancer chemotherapy. The resistance of tumor cells to more than one cyt...
Antimicrobial resistance of Shigella isolates in Bangladesh, during 2001-2002, was studied and compared with that of 1991-1992 to identify the changes in resistance patterns and trends. A significant increase in resistance to trimethoprim-sulphamethoxazole (from 52% to 72%, p < 0.01) and nalidixic acid (from 19% to 51%, p < 0.01) was detected. High, but unchanged, resistance to tetracycline, am...
BACKGROUND Obesity in children is now an increasing health risk worldwide in which the insulin-resistance can be present. Studies have linked a diet rich in n-3 fatty acids with a lower prevalence of insulin-resistance. OBJECTIVE To compare the levels of eicosapentaenoic acid among obese children with and without insulin-resistance. MATERIALS AND METHODS In 56 randomly school-age children w...
background bacterial resistance to antibiotics has become a major source of concern for public health. pseudomonas aeruginosa strains are important opportunistic pathogens. these bacteria have a high resistance to a wide range of existing antimicrobials and antibiotics. objectives the present study was performed to evaluate the frequency of kpc in p. aeruginosa isolated from clinical samples of...
as the canon is shaped by white male standards rewriting the canonical works of literature is one of the ways through which postcolonial writers subvert the authority of the masters. writing in the language of the masters the colonized writers use the very suppressive tool in the hands of the masters i.e. their language to question the validity of their norms. regarded by most critics to be the...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
The effects of pH (4.0–5.5), acid identity (acetic, citric, lactic, malic, and hydrochloric), and the induction of pH-dependent stationary phase acid resistance on the radiation resistance of E. coli O157:H7 Ent-C9490 was studied using cells grown in Tryptic Soy Broth with and without dextrose (induced and non-induced to acid resistance) and then resuspended in brain–heart infusion broth contai...
BACKGROUND The prevalence of resistance to rifampicin and fusidic acid among Malaysian strains of methicillin-resistant Staphylococcus aureus (MRSA) is increasing. This study aimed to determine the mechanisms of rifampicin and fusidic acid resistance and the genetic diversity of MRSA strains from a Malaysian tertiary hospital. METHODS Minimum inhibitory concentrations (MIC) for 21 MRSA strain...
conclusions there are many of different species of lactobacillus probiotics in traditional dairy products of the markazi province, based on the findings of this study. it is recommended for researchers to isolate these strains and investigate their probiotic characteristics in order to reproduce them for use in food production as well as for medical treatment. results nineteen gram-positive and...
