...icius was collected from poultry flocks of Punjab Pakistan for isolation of IBD virus by inoculating in embryonated chicken eggs through chorioallantoic membrane. The two hundred birds were divided into 4 groups A, B, C and D). The birds in group A were commercial broiler chicks having maternal derived antibodies and were challenged with IBDV field isolate at the rate of 0.1ml of EID50 (virus titer 105.50/100μl) on 2nd week of age thro...

...culating in the Egyptian poultry flocks during 2015 -2016 was conducted. Twenty one vaccinated chicken flocks suffering from different form of lymphomas, representing different governorates in the Egyptian Delta, were screened for MDV infection. Pathological findings in the visceral tumours and presence of viral DNAs with variable mitotic figures were observed in the examined visceral organs. Eight samples were screened positive for the major MDV-encoded oncog...

...ed significant losses in poultry flocks throughout Pakistan in recent years. To identify the serotype and gain a better understanding of the genetic properties of the FAdV strains responsible for recent outbreaks, the sequence analysis of hexon gene of 10 isolates associated with IBH and HPS was determined. Sequence alignment and phylogenetic analysis based on direct sequencing of hypervariable region of hexon gene grouped these sequences into two distinct gro...

... is still a havoc to the poultry flocks and outbreaks have occurred even in vaccinated flocks. Commercial Newcastle disease virus vaccines can provide various levels of protection against challenge with different NDV genotypes, raising the importance of the relationship between vaccines and field strains. The aim of the current work is to evaluate the effect of moisture percentage and pH on the persistence of velogenic NDV genotype VII in the poultry manure wh...

...presenting 1180 backyard poultry flocks were collected based on the surveillance conducted by the GOVS (General Organization for Veterinary Services), Egypt during the period from May 2017 to August 2018. 11 positive cases were confirmed in seven governorates with a prevalence rate of 0.93% and the positive samples were mainly located in Upper Egypt. The sequence of partial HA gene was performed for 10 positive samples and they were genetically characterized a...

...sues were collected from poultry flocks showing clinical signs of HHS and investigated using PCR assay for FAdVs. The FAdVs were detected in 8 samples collected from different flocks. Positive PCR amplicons were sequenced to genetically identify the FAdVs. Phylogenetic analysis revealed two distinct clusters among FAdVs. One cluster containing 3 strains belonged to the FAdV- C species and serotyped as FAdV-4 and showed close proximity at the nucleotide level. ...
