A total of 205 Escherichia coli isolates from 88 diarrheal weanling (4- to 10-week-old) pigs from 59 farms were tested by slide agglutination for K88, K99, F41, and 987P antigens. K88 antigen was detected in 61% of the isolates representing 60% of the pigs and 56% of the farms. K88 antigen was associated with serogroup O149 and 91% of the K88+ isolates. K99, F41, and 987P were not detected. Of ...

Identification of Escherichia coli causing porcine postweaning diarrhea requires knowledge regarding the prevalent pathotypes within a given region. A total of 100 Escherichia coli isolates from piglets with diarrhea in Londrina city, Parana State, South Brazil, were screened for the presence of genes for F4, F5, F6, F18, F41 fimbrial antigens by specific probes and for enterotoxins (STa, STb, ...

Plasmid DNA hybridization with probes for virulence factors used for basic replicons of plasmids was used to identify the virulence plasmids of a collection of enterotoxigenic Escherichia coli isolates from cattle. The virulence probes were derived from the genes coding for the heat-stable enterotoxin STaP and for the F5 (K99) and F41 fimbrial adhesins. The replicon probes were derived from 16 ...

We model the world economy as one system of endogenous input-output relationships subject to frictions and study how world’s structure GDP change due changes in frictions. derive a sufficient statistic identify from observed matrix, which we fully match for year 2011. show internal impact whole that they have much larger effect on than external also use our approach role during Great Recession ...

A clone encoding the F41 f imbnal sub-unit gene from E coli B41, was isolated from an B1BL3 library using an oligonucleotide based on the published N-termlnal amino acid sequence (1). The DNA sequence of an t I66bp fragment revealed an open reading frame encoding a protein of 277 amino acids including a 22 amino acid leader sequence (dash underlined). This corresponds to a mature protein of 290...

This paper evaluates the hypothesis that during the 2008-2009 collapse in international trade, imports of higher quality goods experienced larger reductions compared to low-quality imports, using data on U.S. imports disaggregated by HS-10 product category and source country. We find little, if any, robust econometric evidence in support of this hypothesis. JEL Classifications: F41, F42
