Abstract An outbreak of H5N1 highly pathogenic influenza A virus (HPIAV) has been detected in dairy cows the United States. Influenza (IAV) is a negative-sense, single-stranded, RNA that not previously associated with widespread infection cattle. As such, cattle are an extremely under-studied domestic IAV host species. receptors on cells sialic acids (SAs) bound to galactose either α2,3 or α2,6 linkage. Human IAVs preferentially bind SA-α2,6 (human receptor), whereas avian have preference for (avian receptor). The receptor can further be divided into two receptors: isolated from chickens generally more tightly SA-α2,3-Gal-β1,4 (chicken duck SA-α2,3-Gal-β1,3 (duck We found all were expressed, different degree, mammary gland, respiratory tract, and cerebrum beef and/or human widely expressed bovine chicken dominated tract.

The rapid geographic spread of the highly pathogenic avian influenza (HPAI) A(H5N1) virus in poultry, wild birds, and other mammalian hosts, including humans, raises significant health concerns globally. recent emergence HPAI agricultural animals such as cattle goats indicates ability to breach unconventional host interfaces, further expanding range.

However, long-standing viewpoint has been challenged by outbreaks dairy cows United States.

The widespread H5 clade 2.3.4.4b highly pathogenic avian influenza virus (HPAI) poses a significant threat to both domestic and wild mammals because of its rapid genetic evolution, cross-species transmissibility, host-range expansion. increasing number cases in mammalian species highlights the need for proactive measures driven by One Health approach. In this study, we explored potential use previously developed Newcastle disease (NDV)-vectored vaccine expressing hemagglutinin (rK148/22-H5) preclinical BALB/c mouse model. Two doses intramuscular vaccination with viable (107 EID50/0.1 mL) or inactivated rK148/22-H5 provided protection against lethal H5N1 HPAI. A greater than 100-fold reduction lung viral load was observed vaccinated group compared control group. Consistently, co-housed contact mice survived without evidence infection, whereas those became infected succumbed disease. demonstrated as HPAI candidate mammals, warranting further steps advance into clinical trials captive species.

The present study aimed to determine the dynamics of influenza A virus (IAV) infection in two endemically infected farms (F1 and F2), where a longitudinal follow-up piglets was performed from birth 8-12 weeks age. During study, highly virulent isolate porcine reproductive respiratory syndrome (PRRSV) introduced on both farms. This allowed us examine impact such introduction patterns infection, disease, antibody response pigs IAV infection. new PRRSV strain coincided with change In F1, cumulative incidence increased 20% before outbreak 67.5%, together existence animals that tested positive for (RT‒qPCR) nasal swabs or more consecutive samples.
