The effects of animal agriculture on the spread of antibiotic resistance (AR) are cross-cutting and thus require a multidisciplinary perspective. Here we use ecological, epidemiological, and ethnographic methods to examine populations of Escherichia coli circulating in the production poultry farming environment versus the domestic environment in rural Ecuador, where small-scale poultry producti...

Ducks and in-contact backyard chickens on 20 smallholder backyard farms in 4 districts of Shiraz, Southwest of Iran, were monitored for antibodies against H9N2 avian influenza virus using hemagglutinationinhibition (HI) test. A total of 200 unvaccinated ducks and backyard chickens were sampled. The mean H I titers and seroprevalence in ducks and backyard chickens were 8.3, 5.7 and 78.4, 62.9%, ...

Since 2002, following its introduction, the lineage 5d Newcastle disease virus (so-called Goose paramyxovirus - GPMV) strain has caused numerous disease outbreaks among commercial and backyard poultry in South Africa, raising questions about the ability of commercially available Newcastle disease vaccines to fully protect poultry against the strain.

The use of different types of Newcastle disease (ND) vaccine in different vaccination schemes has decreased the incidence of velogenic Newcastle disease (VND) in commercial poultry worldwide. In under-developed countries like Pakistan, these vaccination schemes are not successful due to free-range and backyard poultry production. This trial was conducted in 90 experimental chickens to develop a...
