A Brief Introduction to Influenza A Virus in Swine

Influenza A viruses (IAV) of the Orthomyxoviridae virus family cause one of the most important respiratory diseases in pigs as well as humans. Repeated outbreaks and rapid spread of genetically and antigenically distinct IAVs represent a considerable challenge for animal production and public health. This overlap between human and animal health is a prime example of the “One Health” concept. Although only subtypes of H1N1, H1N2, and H3N2 are endemic in swine around the world, considerable diversity can be found not only in the hemagglutinin (HA) and neuraminidase (NA) genes, but in the other 6 genes as well. Human and swine IAV have demonstrated a particular propensity for interspecies transmission in the past century, leading to regular and sometimes sustained, incursions from man to pig and vice versa. The diversity of IAV in swine remains one of the critical challenges in diagnosis and control of this important pathogen for swine health, and in turn contributes to a significant public health risk.

Publication date: Available online 19 April 2019Source: Journal of Pharmaceutical and Biomedical AnalysisAuthor(s): Faegheh Farhadi, Saba Soltani, Satar Saberi, Mehrdad IranshahiAbstractFerula ovina (Boiss.) Boiss is one of the most important endemic medicinal plants in Iran, which has three main terpenoid compounds including ferutinin, stylosin and tschimgine. Ferutinin is the strongest natural phytoestrogen that has agonistic activity on estrogen receptors, particularly α-receptors. To determine the amount of ferutinin in F. ovina roots, we firstly used HPLC-UV method. In the HPLC method, the resolution of ferutini...

Authors: Sofizadeh A, Hanafi-Bojd AA, Shoraka HR Abstract Background &objectives: Zoonotic cutaneous leishmaniasis (ZCL) is among the most endemic zoonotic diseases in Golestan Province of Iran. The aim of this study was to find the high risk areas of this infection by considering the distribution of reservoirs and human infection. Methods: A cross-sectional study was conducted, in which Rhombomys opimus (Gerbils) were captured from different collection sites across the Golestan Province, Iran. records about the occurrence of Rh. opimus in the Province was obtained from earlier studies and were gathered in ...

Authors: Baruah A, Hazarika RA, Barman NN, Islam S, Gulati BR Abstract Background &objectives: Assam is the most vulnerable state for Japanese encephalitis (JE) in India. The situation warrants characterization of epidemiological patterns of JE in vectors, pigs and human population. This investigation was aimed to determine the relative abundance of mosquito species and seroprevalence of JE in pigs in order to draw an epidemiological association with reported human JE cases in Assam. Methods: Pig sera and mosquitoes from selected farms in Sivasagar and Kamrup districts of Assam were collected fortnightly fo...

Authors: Kadian K, Vijay S, Rawal R, Singh J, Anvikar A, Pande V, Sharma A Abstract Background &objectives: Plasmodium parasite harbours unique methylerythritol phosphate (MEP) pathway which is obligatory for the biosynthesis of isoprenoids. In malaria parasites, the isoprenoids are indispensable during hepatic, erythrocytic and gametocytic stages. Owing to the criticality of MEP pathway and the potential of its enzymes to act as antimalarial drug target, this study comprehensively investigated the genetic diversity and structural composition of 4-diphosphocytidyl-2C-methyl-D-erythritol kinase (IspE), fourth en...

Since the emergence of 2009 pandemic H1N1 (H1N1pdm) FLUAV, many outbreaks of respiratory disease were observed in pig herds. The aim of this study was to evaluate FLUAV infection in swine in 48 pig farms located in seven Brazilian states...
