Data Parameters From Participatory Surveillance Systems in Human, Animal, and Environmental Health From Around the Globe: Descriptive Analysis.

Background: Emerging pathogens and zoonotic spillover highlight the need for One Health surveillance to detect outbreaks as early as possible. Participatory surveillance empowers communities to collect data at the source on the health of animals, people, and the environment. Technological advances increase the use and scope of these systems.

Seroprevalence of the viral pig diseases among backyard pigs in Chiang Mai, Thailand.

The Participatory One-Health Disease Detection project (PODD) (www.cmonehealth.org) developed a health-based surveillance system with the local government of Chiang Mai community ownership that has been created a mobile application on smartphone for reporting an abnormal event, especially animal health.

A Knowledge, Attitudes and Practices (KAP) survey on canine rabies prevention and control in four rural areas of Sri Lanka.

Rabies is a fatal viral disease that affects all mammals. It causes an estimated 59,000 human deaths worldwide annually. Dogs are the main reservoir and transmitter of rabies to human in Sri Lanka.

A Participatory System for Preventing Pandemics of Animal Origins: Pilot Study of the Participatory One Health Disease Detection (PODD) System.

Background: Aiming for early disease detection and prompt outbreak control, digital technology with a participatory One Health approach was used to create a novel disease surveillance system called Participatory One Health Disease Detection (PODD). PODD is a community-owned surveillance system that collects data from volunteer reporters; identifies disease outbreak automatically; and notifies the local governments (LGs), surrounding villages, and relevant authorities. This system provides a direct and immediate benefit to the communities by empowering them to protect themselves.

Application of a non-species dependent ELISA for the detection of antibodies in sera of Burkholderia pseudomallei-immunized goats.

A modified, non-species dependent ELISA was performed to detect antibodies in sera of Burkholderia pseudomallei-immunized goats using protein G- or protein A-peroxidase conjugates. The rise of antibody titers during the immunization period exhibited corresponding results by modified ELISA comparison to conventional ELISA and the IHA. Regarding the increase of antibody levels from the pre-immunized baseline to the post-immunized status, the antibody titer detected by modified ELISA was higher than IHA but lower than conventional ELISA.

A cross-sectional study of Salmonella in pork products in Chiang Mai, Thailand.

The occurrence of Salmonella in food of animal origin in Chiang Mai province was investigated by using a cross-sectional study during several phases of the pork production chain (cutting, transport, and retail) and of the environment in the cutting unit of a slaughterhouse. In total, 173 pork samples were obtained during the cutting phase, 173 samples from transported pork, 200 samples from retail products, and 300 samples from the slaughterhouse environment. Salmonella was detected in 55.

Cross-sectional study of Trichinella spp in pigs in CDR, Nepal using pepsin digestion and ELISA serology.

This epidemiological cross-sectional study was conducted in five major pig-producing districts of CDR, Nepal from November 2006 to April 2007. A total of 576 slaughtered pigs were randomly selected and diaphragmatic crus muscles (n = 551), corresponding sera (n = 487) and sera only (n = 25) were collected from them. Meat samples were examined by pepsin digestion to evaluate for larvae of Trichinella spp.

The epidemiology of Dirofilaria immitis infection in outpatient dogs at Chiang Mai University Small Animal Hospital, Thailand.

Five hundred eighty-nine dog blood samples from the small animal hospital of Chiang Mai University were examined for Dirofilaria immitis prevalence using a microhematocrit tube technique for microfilaria detection. In parallel, a once a month follow-up study on 36 D. immitis negative dogs was conducted to detect the time of acquiring infection in each animal.

Microbial contamination of pig carcasses at a slaughterhouse in Vientiane capital, Lao PDR.

A cross-sectional study was conducted to determine microbial contamination of pig carcasses at a slaughterhouse in Vientiane, capital of Lao People Democratic Republic (Lao PDR). Between November 2004 and April 2005, 62 pig carcasses were randomly selected. From each carcass, pooled swabs (from "1" prior to and "2" after evisceration) and 25 g of tissue of mesenteric lymph nodes (MLN) were collected.
