Abstract

Infectious bronchitis virus (IBV) infection continues to cause economically important diseases in poultry while different geno- and serotypes continue to circulate globally. Two infectious bronchitis viruses (IBV) were isolated from chickens with respiratory disease in Sudan. Sequence analysis of the hypervariable regions of the S1 gene revealed a close relation to the QX-like genotype which has not been detected in Sudan before. Whole genome analysis of IBV/Ck/Sudan/AR251-15/2014 isolate by next generation sequencing revealed a genome size of 27,646 nucleotides harbouring 13 open reading frames: 5'-1a-1b-S-3a-3b-E-M-4b-4c-5a-5b-N-6b-3'. Highest nucleotide sequence identity of 93% for the whole genome was found with the Chinese IBV strain Ck/CH/LHLJ/140906, the Italian IBV isolate ITA/90254/2005 and the 4/91 vaccine strain. Phylogenetic analysis of the S1 gene revealed that the IBV/Ck/Sudan/AR251-15/2014 isolate clustered together with viruses of the GI-19 lineage. Recombination analysis gave evidence for distinct patterns of origin of RNA in the Sudanese isolate in multiple genes. Several sites of recombination were scattered throughout the genome suggesting that the Sudan-QX-like strain emerged as a unique recombinant from multiple recombination events of parental viruses from 4/91, H120 and ITA/90254/2005 genotypes. The Sudanese QX-like isolate is plausibly genetically different from IBV strains previously reported in Africa and elsewhere.

Abstract

Salmonella enterica subsp. enterica serovar Gallinarum biovar Gallinarum (SG) causes fowl typhoid (FT), a septicaemic disease which can result in high mortality in poultry flocks. The absence of flagella in SG is thought to favour systemic invasion, since bacterial recognition via Toll-like receptor (TLR)-5 does not take place during the early stages of FT. In the present study, chicks susceptible to FT were inoculated with a wild type SG (SG) or its flagellated motile derivative (SG Fla(+)). In experiment 1, mortality and clinical signs were assessed, whereas in experiment 2, gross pathology, histopathology, systemic invasion and immune responses were evaluated. SG Fla(+) infection resulted in later development of clinical signs, lower mortality, lower bacterial numbers in the liver and spleen, and less severe pathological changes compared to SG. The CD8(+) T lymphocyte population was higher in the livers of chicks infected with SG at 4 days post-inoculation (dpi). Chicks infected with SG had increased expression of interleukin (IL)-6 mRNA in the caecal tonsil at 1 dpi and increased expression of IL-18 mRNA in the spleen at 4 dpi. In contrast, the CD4(+) T lymphocyte population was higher at 6 dpi in the livers of birds infected with SG Fla(+). Therefore, flagella appeared to modulate the chicken immune response towards a CD4(+) T profile, resulting in more efficient bacterial clearance from systemic sites and milder infection.
