The prevalence of Infectious Bronchitis (IB) in some chicken farms in Egypt: I. Spotlight on the status of IB outbreaks in some chicken flocks [PDF]

Journal of Veterinary Medical Research, 2010
Twenty five isolates of IBV were isolated from 36 broiler and layer chicken farms collected from 13 governorates during 2 years started from January 2003. Sixteen farms were vaccinated against IB, and 9 farms were not vaccinated.

The prevalence of Infectious Bronchitis (IB) in some chicken farms in Egypt: III. Cross protection of vaccinated chickens versus field IB virus [PDF]

Journal of Veterinary Medical Research, 2010
Four groups of one-day-old SPF chicks were inoculated with the four IBV variants at 1 day old to study the virulence of these isolates. The results at 2 weeks post infection (PI) revealed that all isolates were able to induce serological resposne ...

The prevalence of Infectious Bronchitis (IB) outbreaks in some chicken farms: II. Molecular characterization of field isolates of IB virus [PDF]

Journal of Veterinary Medical Research, 2010
Twenty five isolates of IBV were isolated from 36 broiler and layer chicken farms collected from 13 governorates during 2 years started from January 2003. All the examined farms were vaccinated using the commercial live IB-H120 vaccine in addition to the

Low pathogenic avian influenza virus isolates with different levels of defective genome segments vary in pathogenicity and transmission efficiency

Veterinary Research, 2020
Defective interfering particles (DIPs) of influenza virus are generated through incorporation of highly truncated forms of genome segments, mostly those coding polymerase complex proteins (PB2, PB1, PA).

Bacterial and viral rodent-borne infections on poultry farms. An attempt at a systematic review

Journal of Veterinary Research, 2023
Rodents are quite common at livestock production sites. Their adaptability, high reproductive capacity and omnivorousness make them apt to become a source of disease transmission to humans and animals.
