Aquaculture is rapidly growing in economic importance in the USA, where California (CA) is considered as an emergent leader aquaculture industry worth an estimated $110 million per year. The primary aquaculture species in the state are salmonids, particularly Oncorhynchus sp. However, these fish are affected by many endemic infectious agents such hematopoietic necrosis virus (IHNV), cutthroat trout virus (CTV), bacterial kidney disease (BKD), Flavobacterium columnare and F. psychrophilum.
Transmission of infectious diseases mostly occurs due to contacts among infected and susceptible individuals. Therefore, the characterization of the contact patterns among individuals is a prerequisite to better understand and even predict the spread of diseases in a population. California is one of the most important states for livestock production and trade, particularly cattle and poultry.
Workshop intended to provide hands-on-practice using the Disease BioPortal platform (http://bioportal.ucdavis.edu), which is an on-line, user-friendly, tool for the advanced integration, visualization and analysis of genomic, epidemiologic and environmental data to support real-time decision making.
Aquaculture is rapidly growing in economic importance in the USA, where California (CA) is considered as an emergent leader aquaculture industry that worth an estimated $110 million [1]. Primary aquaculture species in the state are rainbow trout and various salmon species for which endemic infectious hematopoietic necrosis virus (IHNV), an acute systemic disease [2] and notifiable for the World Animal Health Organization (OIE), that causes high mortality and significant economic and social losses in hatchery stocks and wild salmonids in fresh waters [3].
This WP will describe spatial and temporal dynamics of fish transportation and characterize the contact network patterns among the fish holdings based on the transportations, characterize infection-inducing contact patterns, identify the highly connected sites, and elucidate implications of the contact pattern on controlling disease spread.
The meat and cattle industry is the largest segment of U.S. agriculture. In 2015 the US commercial slaughter 28.74 million head with the commercial carcass weight of 23.69 billion pounds (National Cattlemen’s Beef Association). Based on the data obtained from USDA in 2015, 141,450 carcasses were condemned in the US which is approximately 0.5% of the total cattle carcasses produced in the US.
The recent cases of highly pathogenic avian influenza (HPAI) in a commertial Turkey flock in Stanislaus country (H5N8, Jan 2015) and a commertial poultry flock (broiler chickens and ducks) in Kings county (H5N8, Feb 2015) highlights the urgent need to develop and implement solutions to protect California poultry operations (PO) against avian influenza (AI) outbreaks.
The goal of this interdisciplinary, multi-institution, research-extension project within the "Critical Agricultural Research and Extension (CARE)" priority is to develop an innovative early-warning system for better prevention and control of Avian Influenza (AI) outbreaks in US poultry industry.
The Center for Animal Disease Modeling and Surveillance (CADMS) at the University of California Davis (Principal Investigator, Dr. Beatriz-Martinez Lopez) proposes to work collaboratively with and provide epidemiological and information management development and support services to the Iowa State University Veterinary Diagnostic Laboratory (Principal Investigator, Dr.
