Abstract
Background and Aim Campylobacteriosis causes gastrointestinal tract lesions in adults and children and may result in severe complications. The primary sources of infection are infected animals and animal products. Immunochemical methods effectively diagnose intestinal infections but require highly specific antigens to detect their antibodies. This study aimed to obtain two recombinant immunogenic antigens of Campylobacter jejuni, an outer membrane protein with a molecular weight of 18 kDa (Omp18) and the major outer membrane protein (MOMP) with a molecular weight of 45 kDa, and evaluate their suitability for the serological diagnosis of campylobacteriosis using immunochromatographic assay (ICA). Materials and Methods The C. jejuni Omp18 and MOMP gene sequences were synthesized de novo (Macrogen, Korea) and cloned into the pET32 expression plasmid. Using these genetic constructs, electrocompetent cells of the Escherichia coli BL21 strain were transformed and cultured under various conditions. Antigens were purified and refolded using metal affinity chromatography. The properties of the purified proteins were studied by western blotting, liquid chromatography with tandem mass spectrometry, and enzyme-linked immunosorbent assay (ELISA). Results We developed two recombinant E. coli BL21 cells producing rOmp18 and Recombinant MOMP (rMOMP) antigens with molecular weights of 36 and 64 kDa, respectively. Amino acid sequence analysis of the obtained antigens showed complete homology with the reference sequences in the PubMed NCBI database. Western blotting using positive-control sera demonstrated the specificity of the recombinant antigens. The results of ELISA with 94 bovine sera showed the interaction of recombinant antigens with specific antibodies. Conclusion The obtained rOmp18 and rMOMP antigens can detect antibodies in the serum of infected or recovered animals and can be used to develop ICA.

Abstract
The accurate and rapid detection of Campylobacter spp. is critical for optimal surveillance throughout poultry processing in the United States. The further development of highly specific and sensitive assays to detect Campylobacter in poultry matrices has tremendous utility and potential for aiding the reduction of foodborne illness. The introduction and development of molecular methods such as polymerase chain reaction (PCR) have enhanced the diagnostic capabilities of the food industry to identify the presence of foodborne pathogens throughout poultry production. Further innovations in various methodologies, such as immune-based typing and detection as well as high throughput analyses, will provide important epidemiological data such as the identification of unique or region-specific Campylobacter. Comparable to traditional microbiology and enrichment techniques, molecular techniques/methods have the potential to have improved sensitivity and specificity, as well as speed of data acquisition. This review will focus on the development and application of rapid molecular methods for identifying and quantifying Campylobacter in U.S. poultry and the emergence of novel methods that are faster and more precise than traditional microbiological techniques.

Abstract
The genus Yersinia includes species with a wide range of eukaryotic hosts (from fish, insects, and plants to mammals and humans). One of the major outer membrane proteins, the porin OmpC, is preferentially expressed in the host gut, where osmotic pressure, temperature, and the concentrations of nutrients and toxic products are relatively high. We consider here the molecular evolution and phylogeny of Yersinia ompC. The maximum likelihood gene tree reflects the macroevolution processes occurring within the genus Yersinia. Positive selection and horizontal gene transfer are the key factors of ompC diversification, and intraspecies recombination was revealed in two Yersinia species. The impact of recombination on ompC evolution was different from that of another major porin gene, ompF, possibly due to the emergence of additional functions and conservation of the basic transport function. The predicted antigenic determinants of OmpC were located in rapidly evolving regions, which may indicate the evolutionary mechanisms of Yersinia adaptation to the host immune system.

Abstract
Pork meat is one of the major sources for human infections with Salmonella enterica subspecies enterica serovars. Further, zoonoses caused by S. enterica subspecies enterica serovars are responsible for substantial economical losses in industrial countries. Quick and reliable detection of this infection is urgently needed to improve consumer security. Due to its capability to identify infections independent of the species, a competitive ELISA is the preferable method for the detection of anti-Salmonella antibodies in serum. Recombinant antibody fragments (scFvs) were isolated from the naive human antibody gene library HAL7 by phage display. Recombinant produced outer membrane protein D (OmpD) of Salmonella Typhimurium was used as antigen. The characterization of the isolated single chain Fv (scFv) antibodies was done by enzyme-linked immunosorbent assay (ELISA), immunoblot, sequencing, epitope mapping and size exclusion chromatography (SEC). The detection of anti-OmpD IgGs in swine sera by competitive ELISA was shown in a proof of principle concept. Furthermore, the developed competitive ELISA would be compatible to a recently published DIVA vaccine, allow to distinguish between infected and vaccinated pigs.

Abstract
Campylobacter species are a group of spiral-shaped bacteria that can cause disease in humans and animals. We developed a high-affinity monoclonal antibody (MAb) probe that recognizes Campylobacter jejuni cells. Cell suspensions grown under microaerobic conditions at 42 degrees C for 20 h on Bolton agar plates with lysed horse blood were used as live and heat-killed preparations, centrifuged at 8,000 x g for 20 min, and resuspended in carbonate buffer (pH 9.6) for coating on the enzyme-linked immunosorbent assay plates. BALB/c mice were immunized with C. jejuni sonicated cells at 10(7) CFU/ml to generate MAb-producing hybridoma clones. Of about 500 initial hybridoma clones, MAb 33D2, which reacted with C. jejuni and Campylobacter coli, was selected for further evaluation. MAb 33D2 is in the immunoglobulin subclass G2a and had relatively weaker reactivity with the C. coli strains tested. MAb 33D2 did not show any cross-reactions with the nine non-Campylobacter bacteria tested in the enzyme-linked immunosorbent assay and had a stronger affinity for C. jejuni as live versus heat-killed cells. In Western blot assays, MAb 33D2 recognized two major antigens of 62 and 43 kDa in extracts from C. jejuni cells but only one antigen of 62 kDa in extracts from C. coli cells.

Abstract
Campylobacter species are major enteric pathogens causing diarrhea illness in humans and animals. Immunological tests are needed for accurate and rapid identification of C. coli, in conjunction with the use of standard biochemical tests. We initiated the creation of monoclonal antibodies (MAbs) using whole C. coli cells as antigen. Four positive clones were identified, namely MAb2G6, MAb3B9, MAb4A10 and MAb5B9. Dot-blot assay and ELISA revealed that only MAb2G6 did not cross react with C. jejuni and other Campylobacter isolates. As demonstrated by dot-blot assay, MAb2G6 reacted with all 23 C. coli isolates tested but did not react with 29 isolates of C. jejuni, 3 other Campylobacter spp. isolates and 19 non-Campylobacter isolates, with the lowest detection limit was in the range of 10(3) to 10(4) bacteria. Western blots and dot blots showed that the antigen of MAb2G6 was a native protein, with immunoprecipitation assay showed that MAb2G6 bound to a protein band of approximately 43 kDa in size, corresponding to major outer membrane protein (MOMP) of C. coli revealed by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF-MS). Immunofluorescence assay (IFA) showed that MOMP of C. coli was indeed the antigen of MAb2G6, with immunogold-electron microscopy demonstrated that MAb2G6 conjugated with immunogold particles bound to all over the surface of C. coli cells. MAb2G6 also showed potential usage in direct detection of C. coli in faecal samples.
