Avian Influenza H5N1 in Egypt: What we Know and What we have to Know?
... has experienced endemic outbreaks of avian influenza viruses (AIV) of subtype H5N1 in poultry since 2008. Since then, these viruses continue to evolve. In 2006-2008, outbreaks were reported mostly during the winter season, but in 2009-2012 they occurred year round. H5N1 AIV succeeded in infecting not only domesticated birds but also many other avian species and mammals. Infections of humans were accompanied by mutations in ...

... species, divided in two outbreaks, one year apart between 2016 and 2017, in a breeding farm in São Paulo State, Brazil. PSHv-1 was detected in 6 species (61 birds) through Nested-PCR, that tested negative for Influenza, Paramyxovirus, Flavivirus, and Adenovirus. Genetic sequencing and phylogenetic analysis support these results....

... the re-emergence of FMD outbreaks in Indonesia. First, the loss of the principle of maximum security. Indonesia’s success in freeing itself from FMD after 100 years is thanks to the implementation of maximum security policy by enacting a country-based system, which is to only import livestock and livestock products into the country from FMD-free countries. Second, the share of imports of boneless frozen beef/buffalo meat originating from India continued...

Therefore, the aim of the this work is to prepare a secure, sterile and potent an oil inactivated vaccine from a recent local isolate genotype VII 1.1 “NDV-CH-EGY-GIZA-VVTNRC-2021” and evaluates its efficacy against commercially available NDV genotype II vaccines in broiler chickens. Eighty chickens were housed in four groups (A, B, C and D) of 20 birds per group. Group A has been received the experimentally prep...

The use of bacteriophages, as a potential replacement, for antibiotics and as food antimicrobial agents to potentially target foodborne pathogens is gaining augmented attention. This study’s goal was to isolate and physiologically characterize lytic bacteriophages against Enteritidis, and to ascertain their efficacy in modulating bacterial population ...

Assessment or maternal antibodies in calves born to naturally infected dams is a matter of interest in order to determine the proper time of vaccination. Twenty-five pregnant Frisian cows in the last stage of pregnancy were naturally infected with BEFV during the Egyptian outbreak in summer 2004. Fo...

In this context, propolis, a natural substance produced by bees, looks like an attractive option owing to its antibacterial action against many pathogens in food. The aim of this study is to investigate the effect of propolis extract (PE) and propolis nanoemulsion (PN) on L. monocyto...
