...justify; ">Virulence and pathogenicity of Newcastle disease virus (NDV) is one of the major determinants for the clinicopathological manifestations in infected hosts. Recent studies showed that the host innate immune responses to infection play important role in the pathologenesis of NDV, and correlate with the severity of the clinical disease. Virulent strains of different genotypes induce distinct pathological manifestations in chicken organs, especially in ...

Phylogenetic analysis of the F and haemagglutinin-neuraminidase (HN) genes indicated that the isolate clustered with the PPMV-1 strains recently reported from Israel within subgenotype VIb. Our findings report the emergence of PPMV-1 in Egyptian pigeons and the potential role the...

Moreover O-antigen serotype was tested by slide agglutination test and a mouse model was built to assess the lethality of the E.coli isolates through subcutaneous-infection. Out of 81 E.coli isolates, the most prevalent gene detected was ompA (90.12%), followed by ETT2 (69.14%), irp2 (54.32%), EAST1 (46.91%...
