Autor: D. Alfi, Mansour Samadpour, Wudeneh Mulugeta, Marilyn C. Roberts, Christopher L. Kitts

Publikováno v: Letters in Applied Microbiology. 40:63-68

Aims: To compare antibiotic resistance and ribotyping patterns ability to identify triplicate isolates sent from a group of 40 Escherichia coli taken from seven host sources. Methods and Results: Of the 120 isolates, 22 isolates were resistant to amp

Prevalence of Shiga Toxin–Producing Escherichia coli in Ground Beef and Cattle Feces from King County, Washington

Autor: G. A. Depavia, Mansour Samadpour, J. Stewart, F. C. Buck, P. Yang, E. Mazengia, D. Alfi, M. Kubler

Publikováno v: Journal of Food Protection. 65:1322-1325

Shiga toxin-producing Escherichia coil (STEC) is increasingly recognized as a common cause of diarrhea. STEC infection is a major public health threat because of its ability to cause serious and potentially life-threatening illnesses. The main reserv

Characterization of the mouse thrombospondin gene and evaluation of the role of the first intron in human gene expression

Autor: Sreelekha Devarayalu, D Alfi, Paul Luo Li, Paul Framson, Paul Bornstein

Publikováno v: Journal of Biological Chemistry. 265:16691-16698

We have isolated the mouse thrombospondin (TS) gene and determined the DNA sequence of the first nine exons and eight introns. Comparison with the human cDNA sequence reveals a high degree of conservation in coding sequences. Exon 3 of the mouse gene

Molecular epidemiology of a fast-food restaurant-associated outbreak of Escherichia coli O157:H7 in Washington State

Autor: Linda M Grimm, Phillip I. Tarr, Jay H Lewis, D. Alfi, Mansour Samadpour, Steve L. Moseley, John Kobayashi, Jerry E. Ongerth, Ann Marie Perdichizzi, Marcia Goldoft

Publikováno v: Journal of clinical microbiology. 33(8)

We studied the molecular epidemiology of the recent fast-food restaurant chain-associated Escherichia coli O157:H7 outbreak in Washington State. Genomic DNAs prepared from strains isolated from 433 patients were probed with radiolabelled Shiga-like t

Molecular epidemiology of Escherichia coli O157:H7 strains by bacteriophage lambda restriction fragment length polymorphism analysis: application to a multistate foodborne outbreak and a day-care center cluster

Autor: Linda M Grimm, Phillip I. Tarr, D. Alfi, Mansour Samadpour, Jerry E. Ongerth, B Desai

Genomic DNAs prepared from 168 isolates of Escherichia coli O157:H7 were analyzed for restriction fragment length polymorphisms on Southern blots probed with bacteriophage lambda DNA. The isolates analyzed included strains from a recent large multist

Autor: Lynne Kiorpes, Ronald G. Boothe, D. Alfi, M. R. Carlson

Publikováno v: Journal of pediatric ophthalmology and strabismus. 22(2)

A colony of Macaca nemestrina monkeys was screened for naturally occurring strabismus. Thirteen cases of naturally occurring strabismus were documented, 12 esotropes and one exotrope. The characteristics of the strabismus in these monkeys were simila
