Multiplex polymerase chain reaction (PCR) assays were developed for detection of pathogenic strains belonging to Escherichia coli serogroups O22 and O91. The O-antigen gene cluster of E. coli O22 was sequenced to identify genes that could be employed as targets for serogroup-specific PCR assays. The wzx and wzy genes in the O-antigen gene clusters of E. coli O22 and E. coli O91 were selected as...

Increasing antibiotic resistance and ever stricter control on antibiotic use are a driving force to develop alternatives to antibiotics. One such strategy is the use of multifunctional Host Defense Peptides. Here we examined the protective effect of prophylactic treatment with the D analog of chicken cathelicidin-2 (D-CATH-2) against a respiratory E. coli infection. Chickens were treated with D...
Colibacillosis results from infection with avian pathogenic Escherichia coli bacteria. Healthy broilers are resistant to inhaled E. coli, but previous infection with vaccine or virulent strains of Infectious Bronchitis Virus (IBV) predisposes birds for severe colibacillosis. We investigated whether IBV affects recruitment and function of phagocytic cells and examined NO production, phagocytic a...
The molecular revolution in clinical and diagnostic microbiology has been fueled by such innovative technologies as polymerase chain reaction (PCR), matrix-assisted laser desorption ionization-time of flight mass spectroscopy (MALDI-TOF) and 16S rRNA and full genome sequencing [1,2]. This revolution has spurred numerous advancements in the field of microbiology in the area of rapid diagnostics,...
Autotransporters are secreted bacterial proteins exhibiting diverse virulence functions. Various autotransporters have been identified among Escherichia coli associated with intestinal or extraintestinal infections; however, the specific distribution of autotransporter sequences among a diversity of E. coli strains has not been investigated. We have validated the use of a multiplex PCR assay to...
