Transport Capacity of Salmonella typhimurium by Ascaridia galli Body Parts

The relationship between Salmonella tyohimurium and Ascaridia galli is a particular important issue in poultry, where both parasites are likely common. Several lines of evidence suggest that the nematode is responsible for the mechanical transmission of Salmonella. In an in vitro system, the parasite-parasite relation between Salmonella typhimurium and Ascaridia galli was studied. A total of312 adult’s worms (149 males and 163 females) were usedand 105 worms were ligatured by a thread tied around the body behind the mouth and anus. We evaluated the transport capacity of Salmonella typhimurium by different body parts of A. galliby placing the nematode and the bacteria in an in vitro medium and then incubated in a Salmonellas elective media. We observed association on the surface of body wall, digestive tract and on the uterus/eggs of both ligatured and unligatured male and female Ascaridia galli worms. These worms may effectively appear as vectors of Salmonella transmission. Control of Ascaridia galli may also contribute to the control of Salmonella infections.
