Effects of medicinal plant powder as feed additives on growth performance, carcass characteristics, and immune response of Coturnix japonica against avian influenza and Newcastle disease vaccine virus

AbstractThe purpose of this study was to evaluate the potential effect of different levels ofGracilaria corticata (Gracilaria),Sargassum cristaefolium (Sargassum),Rhus coriaria (sumac), andPunica granatum (pomegranate) peel powdered on growth performance, carcass characteristics, and immune responses of Japanese quails against avian influenza and Newcastle disease killed vaccine virus. A total of 360 one-day-old Japanese quails were randomly distributed into nine dietary treatments with 4 replicates (10 quail/rep). Control group (C) received the diet free of medicinal plants supplementation and the other eight treatments received, 0.5 and 2% medicinal plants and algae-dried powder in diet for the 15  days at the end of experiment (in days 27–42). Live body weight, feed conversion ratio (FCR), carcass characteristics, and immune response evidences were recorded.G.corticata,S.cristafolium,R.coriaria, andP.granatum peel had significant (p

After the initial identification of the H1N1 pandemic influenza strain in Mexico in April 2009 and its subsequent global spread, several monovalent influenza vaccines were developed as part of the pandemic response. Three of these vaccines, Pandemrix, Arepanrix and Focetria were adjuvanted. One of these, the AS03-adjuvanted Pandemrix vaccine, was primarily used in Europe. Following widespread Pandemrix vaccine administration in Scandinavia, an increased risk of narcolepsy was noted in observational studies. Subsequently, this increased risk was also reported in other European countries as well. In contrast, studies from Ca...

In conclusion, co-infection of chicks with AIV and IBV, simultaneously or sequentially, affected the clinical signs, the virus replication dynamics as well as the internal organ integrity. The results proposed that infection with heterologous virus may result in temporary competition for cell receptors or competent cells for replication, most likely interferon-mediated.

In conclusion, oral administration of 1% IMU for six weeks can enhance the immune response after AI-H9N2 vaccination and reduce the pathogenicity of infection in stressed chickens. PMID: 31300109 [PubMed - in process]

Phylogenetic analysis of HA genes revealed that A/chicken/Gansu/XG2/2012 (CK/GS/XG2/12) belonged to clade 2.3.2.1a, while A/environment/Qinghai/1/2013 (EN/QH/1/13), A/chicken/Qinghai/QH1/2015 (CK/QH/QH1/15), A/chicken/Qinghai/QH2/2015 (CK/QH/QH2/15), A/chicken/Qinghai/QH3/2015 (CK/QH/QH3/15), and A/goose/Qinghai/QH6/201...

In 2013, the emergence of H7N9 virus in human beings and persistent human infection in China raised the most serious pandemic threat.

Abstract Avian influenza virus (AIV) is an extraordinarily diverse pathogen that causes significant morbidity in domesticated poultry populations and threatens human life with looming pandemic potential. Controlling avian influenza in susceptible populations requires highly effective, economical and broadly reactive vaccines. Several AIV vaccines have proven insufficient despite their wide use, and better technologies are needed to improve their immunogenicity and broaden effectiveness. Previously, we developed a "mosaic" H5 subtype hemagglutinin (HA) AIV vaccine and demonstrated its broad protection aga...

Abstract Subtype H7 avian influenza viruses have been found to be associated with human infection and represent a risk for global public health. In 2013, the emergence of H7N9 virus in human beings and persistent human infection in China raised the most serious pandemic threat. Here we identified a human monoclonal antibody, P52E03, targeting the hemagglutinin (HA) of subtype H7 influenza viruses (H7 antigen), from a convalescent patient infected with H7N9 in 2017. P52E03 showed in vitro hemagglutination inhibiting (HI) and neutralizing activity against subtype H7 viruses belonging to both North American and Euras...

We describe how CD8+ CTL memory is established following influenza virus infection, and how a robust CTL recall response can lead to more rapid virus elimination by destroying virus-infected cells, and recovery. Exploiting long-term, cross-reactive CTL against the continuously evolving and unpredictable influenza viruses provides a possible mechanism for preventing a disastrous pandemic comparable to the 1918-1919 H1N1 “Spanish flu”, which killed more than 50 million people worldwide.
