Isolation and characterization of a gene involved in hemagglutination by an avian pathogenic Escherichia coli strain.
In this article, we report the isolation and characterization of a gene that may be important in the adherence of avian pathogenic Escherichia coli to the avian respiratory tract. The E. coli strain HB101, which is unable to agglutinate chicken erythrocytes, was transduced with cosmid libraries from the avian pathogenic E. coli strain chi 7122. Enrichment of transductants that could agglutinate...
متن کاملpapA gene of avian pathogenic Escherichia coli.
P fimbrial adhesins may be associated with the virulence of avian pathogenic Escherichia coli (APEC). However, most APECs are unable to express P fimbriae even when they are grown under conditions that favor P fimbrial expression. This failure can be explained by the complete absence of the pap operon or the presence of an incomplete pap operon in Pap-negative APEC strains. In the present study...
متن کاملComplete Genomic Sequence of an Avian Pathogenic Escherichia coli Strain of Serotype O7:HNT
Avian pathogenic Escherichia coli (APEC) is associated with colibacillosis in poultry. Here, we present the first complete sequence of an APEC strain of the O7:HNT serotype and ST73 sequence type, isolated from a broiler with cellulitis. Complete genomes of APEC with distinct genetic backgrounds may be useful for comparative analysis.
متن کاملConstruction of an iss deleted mutant strain from a native avian pathogenic Escherichia coli O78: K80 and in vitro serum resistance evaluation of mutant
BACKGROUND: Colibacillosis, caused by different serotypes of avian pathogenic Escherichia coli (APEC), is one of the important diseases in poultry industry. The isolate O78 is the most prevalent serotype of APEC in Iran. One of the APEC virulence factors, increased serum survival (iss) gene, is related to serum resistance. The usual form of colibacillosis in avian is extraintestinal, and serum ...
متن کاملIncreased Pho regulon activation correlates with decreased virulence of an avian pathogenic Escherichia coli O78 strain.
Avian pathogenic Escherichia coli (APEC) strains are associated with respiratory infections, septicemia, cellulitis, peritonitis, and other conditions, since colibacillosis manifests in many ways. The Pho regulon is jointly controlled by the two-component regulatory system PhoBR and by the phosphate-specific transport (Pst) system. To determine the specific roles of the PhoBR regulon and the Ps...
