Brazil is the world leader in broiler production and export. It achieved this position mainly to its excellent supply chain structure and climate, which favor poultry and grain production throughout its territory. Although Brazilian egg production is not as important as broiler production, this segment presents great potential of increasing its share in the global market. However, as elsewhere ...
We analyzed ≈ 12 years of surveillance data on avian influenza in Hong Kong live poultry markets. A ban on keeping live poultry overnight in these markets reduced virus isolation rates by 84% in chickens (p = 0.006) and 100% (p = 0.01) in minor poultry.
We investigated the influence of a mass poultry vaccination campaign on passive surveillance of highly pathogenic avian influenza subtype (H5N1) outbreaks among poultry in Egypt. Passive reporting dropped during the campaign, although probability of infection remained unchanged. Future poultry vaccination campaigns should consider this negative impact on reporting for adapting surveillance stra...
The extensive system of poultry production (commonly known as “free-range”) is based on the practice of allowing the bird access to foraging areas outside the poultry house. This system was widely practiced prior to the development of more productive strains of poultry and better management facilities (automated feeding and watering, better housing, environmental control) around the middle of t...
Salmonella enterica subsp. enterica serovar Enteritidis is a prominent cause of human salmonellosis frequently linked to poultry products. In Canada, S. Enteritidis phage types 8, 13, and 13a predominate among both clinical and poultry isolates. Here, we report the complete genome and plasmid sequences of poultry isolates of these three phage types.

The global poultry sector is divided into a large-scale commercial sector dominated by international, highly vertically integrated companies, and a small-scale sector that provides up to 90 percent of total poultry production in some of the least developed countries. The fast reproduction cycle, low unit costs, economies of scale in research and appropriation and control of the produce are driv...
OBJECTIVE To identify the risk factors and source of infection leading to human infections with the Influenza A(H7N9) virus in urban and rural areas. METHODS We conducted a case-control investigation to identify potential exposures and risk factors. Controls were randomly selected from the same community as the cases using random digit dialing. We used exact conditional logistic regression to...
In the last two decades, two important avian influenza viruses infecting humans emerged in China, the highly pathogenic avian influenza (HPAI) H5N1 virus in the late nineties, and the low pathogenic avian influenza (LPAI) H7N9 virus in 2013. China is home to the largest population of chickens (4.83 billion) and ducks (0.694 billion), representing, respectively 23.1 and 58.6% of the 2013 world s...
In March 2017, highly pathogenic avian influenza A(H7N9) was detected at 2 poultry farms in Tennessee, USA. Surveillance data and genetic analyses indicated multiple introductions of low pathogenicity avian influenza virus before mutation to high pathogenicity and interfarm transmission. Poultry surveillance should continue because low pathogenicity viruses circulate and spill over into commerc...
