Three gene libraries of Campylobacter jejuni 72Dz/92 DNA were prepared using lambda gt11, pSupercos and pWSK129 cloning vectors. Screening of the libraries with Escherichia coli absorbed antiserum generated against whole C. jejuni revealed several immunoreactive clones of apparent molecular masses 19, 28, 30 and 50 kDa. The most commonly isolated clones expressed 30 kDa protein. The nucleotide sequence of the 1768 bp C. jejuni DNA yielded one complete (ORF2) and two partial open reading frames (ORF1 and ORF3). ORF2 encoded CjaA protein exhibits relevant overall homology to several prokaryotic solute binding proteins (family 3), components of the ABC transport system, while the product of the truncated ORF3 (CjaB protein) shows extensive homology to Gram-negative bacterial proteins, members of the sugar transporter family. The genetic organization of the putative cjaAB operon was studied. The cjaA gene fragment (616 bp) was amplified from three C. jejuni strains isolated from patients with acute bloody diarrhea, whereas it was not amplified from strains which caused acute diarrhea with no blood in the stools. The gene was introduced into avirulent Salmonella typhimurium vaccine strain where it is expressed at a reasonably high level.

Noroviruses (NoVs) are one of the major etiological agents of acute gastroenteritis in all age groups. In this study, we identified an intergenotype NoV recombinant strain in the fecal specimens of two male infants with acute diarrhea in Bangladesh. Phylogenetic analysis showed that the identified strains were recombinant NoV strains with a GII.3 capsid and a GII.16 polymerase gene. The recombination breakpoint was located in the ORF1/ORF2 overlap region. To the best of our knowledge this is the first report of a NoV recombinant GII.16/GII.3 strain worldwide.
