Karl CA, Andres D, Carlos M, Peña M, Juan HO, Jorge O. Farm management practices, biosecurity and influenza a virus detection in swine farms: a comprehensive study in colombia. Porcine Health Manag 2022; 8:42. [PMID: 36199147 PMCID: PMC9532805 DOI: 10.1186/s40813-022-00287-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 07/22/2022] [Accepted: 09/22/2022] [Indexed: 12/01/2022] Open
Abstract
Biosecurity protocols (BP) and good management practices are key to reduce the risk of introduction and transmission of infectious diseases into the pig farms. In this observational cross-sectional study, survey data were collected from 176 pig farms with inventories over 100 sows in Colombia. We analyzed a complex survey dataset to explore the structure and identify clustering patterns using Multiple Correspondence Analysis (MCA) of swine farms in Colombia, and estimated its association with Influenza A virus detection. Two principal dimensions contributed to 27.6% of the dataset variation. Farms with highest contribution to dimension 1 were larger farrow-to-finish farms, using self-replacement of gilts and implementing most of the measures evaluated. In contrast, farms with highest contribution to dimension 2 were medium to large farrow-to-finish farms, but implemented biosecurity in a lower degree. Additionally, two farm clusters were identified by Hierarchical Cluster Analysis (HCA), and the odds of influenza A virus detection was statistically different between clusters (OR 7.29, CI: 1.7,66, p = < 0.01). Moreover, after logistic regression analysis, three important variables were associated with higher odds of influenza detection: (1) “location in an area with a high density of pigs”, (2) “farm size”, and (3) “after cleaning and disinfecting, the facilities are allowed to dry before use”. Our results revealed two clustering patterns of swine farms. This systematic analysis of complex survey data identified relationships between biosecurity, husbandry practices and influenza status. This approach helped to identify gaps on biosecurity and key elements for designing successful strategies to prevent and control swine respiratory diseases in the swine industry.

[PMID: 35392932 PMCID: PMC8988477 DOI: 10.1186/s12985-022-01794-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Accepted: 03/16/2022] [Indexed: 11/25/2022] Open
Abstract
Background Influenza A virus infections occur in different species, causing mild-to-severe symptoms that lead to a heavy disease burden. H1N1, H1N2 and H3N2 are major subtypes of swine influenza A viruses in pigs and occasionally infect humans. Methods A case infected by novel influenza virus was found through laboratory surveillance system for influenza viruses. Clinical specimens were tested by virus culture and/or real-time RT–PCR. The virus was identified and characterized by gene sequencing and phylogenetic analysis. Results In 2021, for the first time in Taiwan, an influenza A(H1N2)v virus was isolated from a 5-year old girl who was suffering from fever, runny nose and cough. The isolated virus was designated A/Taiwan/1/2021(H1N2)v. Full-genome sequencing and phylogenetic analyses revealed that A/Taiwan/1/2021(H1N2)v is a novel reassortant virus containing hemagglutinin (HA) and neuraminidase (NA) gene segments derived from swine influenza A(H1N2) viruses that may have been circulating in Taiwan for decades, and the other 6 internal genes (PB2, PB2, PA, NP, M and NS) are from human A(H1N1)pdm09 viruses. Conclusion Notably, the HA and NA genes of A/Taiwan/1/2021(H1N2)v separately belong to specific clades that are unique for Taiwanese swine and were proposed to be introduced from humans in different time periods. Bidirectional transmission between humans and swine contributes to influenza virus diversity and poses the next pandemic threat.

Abstract
Using Luminex xMAP (x = analyte, MAP = multi-analyte profiling) technology, a serological method for the simultaneous detection of antibodies to Newcastle disease virus (NDV) and avian influenza virus (AIV) was established. Nano-magnetic beads coated with purified NDV protein and AIV nucleoprotein were incubated with serum samples. Using biotinylated rabbit anti-chicken IgY and streptavidin-R-phycoerythrin, the optical signals measured by a Luminex 200 detection system indicated the quantification of NDV or AIV antibodies in the serum. Specific pathogen-free (SPF) chicken serum was used as a negative control. The Luminex xMAP assay developed in this study demonstrated high specificity as there was no cross-reaction with antibodies to infectious laryngotracheitis virus, infectious bronchitis virus, infectious bursal disease virus, avian leukosis virus, and Marek's disease virus. The results from reproducibility experiments showed that intra-coefficients of variation were 3.36 and 9.23% and inter-coefficients of variation were 6.50 and 7.66% for NDV and AIV, respectively. The results also indicated that the Luminex xMAP assay was 16 times more sensitive for NDV antibody detection and 1,024 times more sensitive for AIV antibody detection compared to the enzyme-linked immunosorbent assay (ELISA). A total of 300 chicken serum samples were subjected to both Luminex xMAP assay and ELISA, showing the coincidence rates of 98.67 and 98% for NDV and AIV antibody detection, respectively. This study provides a new method for the simultaneous detection NDV and AIV antibodies in the serum with high specificity and sensitivity.

Abstract
An avian influenza H3N2 virus was isolated from domestic ducks in France in 2016. Although this French H3N2 virus possesses traits of an avian virus, the genetic distances observed for hemagglutinin (HA) and neuraminidase (NA) show that these two genes most likely evolved independently from other avian influenza sequences.

Abstract
One Health is defined as an approach of integrating animal, human, and environmental
health to mitigate diseases. One Health promotes public health by studying all factors,
such as agriculture, food, and water security, mechanisms of toxicity and pathogenesis
of acute and chronic diseases, sociology, economics, and ecosystem health (to name a
few). Such an approach is essential because human, animal, and ecosystem health are
inextricably linked; therefore, with this One Health approach, we are called to work
together to promote, improve, and defend the health and well-being of all by enhancing
cooperation and collaboration between physicians, veterinarians social scientists,
economists, psychologists, legal professionals, philosophers, and other scientific
health and environmental professionals. As such, the One Health movement and approach is
a growing vision in global health and is gaining increasing recognition by national and
international institutions, organizations, stakeholders, NGOs, and health policymakers.
Likewise, the role of world-class universities is pivotal in discovering One Health
scientific knowledge and translating them to policy and evidence-based practices.
Universities have responsibilities to train future professionals capable of solving
global health issues through interdisciplinary scientific knowledge, integrative
approaches to teaching, research collaboration, community linkages, and leadership. This
chapter discusses the importance of One Health and the role of higher education
institutions’ One Health partnerships to improve global health.

Front Microbiol 2016; 7:1068. [PMID: 27458456 PMCID: PMC4937032 DOI: 10.3389/fmicb.2016.01068] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2016] [Accepted: 06/24/2016] [Indexed: 01/26/2023] Open
Abstract
Southern China has long been considered to be an epicenter of pandemic influenza viruses. The special environment, breeding mode, and lifestyle in southern China provides more chances for wild aquatic birds, domestic poultry, pigs, and humans to be in contact. This creates the opportunity for interspecies transmission and generation of new influenza viruses. In this study, we reported a novel reassortant H1N2 influenza virus from pigs in southern China. According to the phylogenetic trees and homology of the nucleotide sequence, the virus was confirmed to be a novel triple-reassortant H1N2 virus containing genes from classical swine (PB2, PB1, HA, NP, and NS genes), triple-reassortant swine (PA and M genes), and recent human (NA gene) lineages. It indicated that the novel reassortment virus among human and swine influenza viruses occurred in pigs in southern China. The isolation of the novel reassortant H1N2 influenza viruses provides further evidence that pigs are “mixing vessels,” and swine influenza virus surveillance in southern China will provide important information about genetic evaluation and antigenic variation of swine influenza virus to formulate the prevention and control measures for the viruses.
