Shiga toxin-producing Escherichia coli (STEC) are a common cause for food-borne diarrheal illness outbreaks and sporadic cases. Here, we report the availability of the draft genome sequences of 228 STEC strains representing 32 serotypes with known pulsed-field gel electrophoresis (PFGE) types and epidemiological relationships, as well as 12 strains representing other diarrheagenic E. coli patho...
The detection of virulence determinants harbored by pathogenic Escherichia coli is important for establishing the pathotype responsible for infection. A sensitive and specific miniaturized virulence microarray containing 60 oligonucleotide probes was developed. It detected six E. coli pathotypes and will be suitable in the future for high-throughput use.
T h e nor thern root-knot nematode, Meloidogyne hapla Chitwood, 1949, parasitizes a number of impor tant crops in Washington (1). M. hapla is widespread on Concord grapes (Vitis labrusca L.), and heavy infestations have been associated with vines with poor growth. All the same, a greenhouse pathogenicity study with an isolate of M. hapla from alfalfa (Medicago sativum L.) showed that Concord gr...
Leaf rust is one of the most important diseases of wheat and is caused by Puccinia triticina, a highly variable rust pathogen prevalent worldwide. Decoding the genome of this pathogen will help in unraveling the molecular basis of its evolution and in the identification of genes responsible for its various biological functions. We generated high quality draft genome sequences (approximately 100...
Cattle are the main reservoirs for Shiga-toxin-producing Escherichia coli (STEC), the only known zoonotic intestinal E. coli pathotype. However, there are other intestinal pathotypes that can cause disease in humans, whose presence has been seldom investigated. Thus, our aim was to identify the effects of anthropic pressure and of wild and domestic ungulate abundance on the distribution and div...
Resistance to Soybean mosaic virus (SMV; Genus Potyvirus; Family Potyviridae) is controlled by single dominant genes at three distinct loci, Rsv1, Rsv3 and Rsv4, in soybean (Glycine max [L.] Merr.). SMV isolates are classified into pathotypes G1 through G7 based on the differential reactions on resistant soybean cultivars. Most SMV isolated in the USA is of the G1 to G3 pathotypes. Since the cu...
Aim In the present study, we investigated the prevalence of E. coli pathotypes and Shigella sero-groups and their antimicrobial profiles among diarrheic children in Nairobi city, Kenya. Background Although diarrheagenic E. coli pathotypes and Shigella sero-groups are leading causes of diarrhea in children under five years in developing countries, their distribution and antimicrobial resistanc...
Clubroot disease resistance has been introgressed from Brassica rapa into canola following different approaches including a B. napus × interspecific cross; however, the details of this cross are not available. To extend our knowledge for introgression to multiple pathotypes, we crossed clubroot-resistant turnip with susceptible and backcrossed F1′s canola. The backcross population was subjected...
To the Editor: Feline coronaviruses (FCoVs) occur as 2 pathotypes, feline infectious peritonitis virus (FIPV) and feline enteric coronavirus (FECV). FECV is common in cats, causing mild transient enteritis in kittens, but is asymptomatic in adult cats. In contrast, FIPV occurs sporadically but is lethal. It replicates in monocytes and macrophages and rapidly disseminates throughout the body cau...
