Latent time period of 15, 15, and 20 min was documented for SEPL01, SEPL13, and SEPL20, respectively, with an average burst size of 110, 32, and 63 PFU CFU-1, respectively. All the three bacteriophages were tolerant of temperature range 4°C-70°C and pH between 3-12, thus providing a broader window of their application throughout the food chain. On chicken breast cuts, phage mix efficiently supported sustained ...

... characterization of GIO serotype of group A rotaviruses from fecal samples collected from camel farms suffering from diarrhea in Alexandria and Esmalia governorates. After preparation of fecal samples and inoculation on MA 104 cell line for five passages, eight isolates were successfully isolated with a clear and reproducible CPE on the inoculated cells. The isolates were identified antigenically using VP6 monoclonal antibodies (MAbs) based antigens capture E...

...ous bursal disease (IBD) serotype 1 viruses continue to cause major economic losses in the Egyptian poultry industry despite the implementation of intensive vaccination programs. A recent increase in IBD related mortality in vaccinated farms prompted this investigation into the genetic character of the circulating IBD virus (IBDV). Bursa and proventriculus samples were RT-PCR tested using novel primers flanking VP2 region coding the two major and two minor hyd...

...ates with different IBDV serotype I strains showed that isolate shared three unique a.a residues at positions 222A, 256I, and 294Ile that were found only in vvIBDV as well as the conserved serine rich heptapeptide region. Giza/2000 showed two additional unique a.a residues at positions 220Phe and 321Thr that resulted from two unique nucleotide substitution at positions 609 (A to T) and 911 (G to A). Surprisingly Giza/2000 shared the unique a.a residue at posit...

Although, the epidemiological investigation and antigenic typing by AC-CLISA test as well as pathogenicity study suggested that IBD field isolates are in the majority of highly virulent pathotype producing acute disease with severe clinical picture. The current study presents evidence of two variant isolates existing in commercial broiler and native Baladi farms with ...
