background: the main goal of the present study was to set up an axenic cultivation of acanthamoeba and assess the pathogenic ability of t4 genotypes from different clinical and environmental strains of acanthamoeba using two physical assays. methods: sixteen acanthamoeba isolates including 10 environmental and 6 clinical strains were cul-tured axenically. axenic cultivation was performed using ...
T cell receptor (TCR) recognition is intrinsically polyspecific. In the field of autoimmunity, recognition of both self- and microbial peptides by a single TCR has led to the concept of molecular mimicry. However, findings made by our group and others clearly demonstrate that a given TCR can also recognize multiple distinct self-peptides. Based on experimental data we argue that recognition of ...
Finished genome sequences are presented for four Escherichia coli strains isolated from bloodstream infections at San Francisco General Hospital. These strains provide reference sequences for four major fimH-identified sublineages within the multilocus sequence type (MLST) ST95 group, and provide insights into pathogenicity and differential antimicrobial susceptibility within this group.
Hasenclever, H. F. (U. S. Public Health Service, Bethesda, Md.), and William O. Mitchell. Antigenic studies of Candida. III. Comparative pathogenicity of Candida albicans group A, group B, and Candida stellatoidea. J. Bacteriol. 82:578-581. 1961.-Since the antigenic differences between Candida albicans group A and C. albicans group B had been established, the problem of a difference in pathogen...
in this research,the authors conducted a study comparing two groups of male and female english language learners studying in a elt institute,in terms of their performance on their achievement test including listening comprehension,vocabulary,grammar,and reading comprehension and found no significant difference between the group except in listening comprehension part of the test in which the f...
background: the aims of this study were to identify blastocystis subtypes (sts) in a cohort of turkish patients with various gastrointestinal symptoms using a novel real time pcr method developed recently for blastocystis detection and assess the relationship between blastocystis sts and patient symptoms. methods: totally, 617 stool samples of patients with gastrointestinal symptoms were examin...
abstract the present study tried to investigate the effect of visual aids (films) on the development of the speech act of disagreement among iranian efl intermediate learners. to this end, the researcher selected 40 homogeneous intermediate learners based on their scores on oxford placement test. .the subjects then divided into control group and experimental group. both classes were tested by ...
Bacterial co-infections can probably influence the pathogenicity of H9N2 low pathogenic avian influenza virus (AIV). This study aimed to evaluate the effect of exposure time to Escherichia coli (O:2) on the pathogenicity of H9N2 AIV in broiler chickens. Three hundred and sixty broiler chickens were randomly allocated to six equal groups. At the age of 26 days, all chicks except groups 5 and 6 w...
