Introduction: is one of the most prevalent zoonotic protozoan parasites worldwide and affects the vast majority of warm-blooded animal species, including humans. Postnatal infection in humans occurs through the ingestion of sporulated oocysts or the oral intake of parasite tissue cysts during the consumption of raw or undercooked meat. In this regard, given their high exposure to oocysts, chickens () raised on the ground constitute a potential source of .
Material And Methods: For the first time in Spain, a survey was undertaken in commercial retail free-range poultry. A total of 50 thighs from different animals were analysed. The samples were homogenised and an acid pepsin digestion procedure was applied prior to molecular analysis. DNA was isolated from meat by qPCR. Two sets of primers were used for DNA amplification targeting the specific sequence of a 529 bp repeat element and another set of primers was utilised for the surface antigen protein-1 gene.
Results: DNA extracted from 5 out of 50 tissue samples was positive for both genes by qPCR amplification.
Conclusion: The 10% prevalence of infection found in commercial free-range chickens raises public health issues.

Ascaridia galli causes weight loss, emaciation, anemia, decreased egg production, and sometimes, intestinal obstruction and death in birds, leading to economic losses in the poultry industry. This research aimed to record the occurrence of A. galli in free-range chickens at farmers' houses in three villages in Ashmoun City, Minoufiya Governorate, Egypt.

Background And Aim: , a nematode that frequently infects the digestive tract of chickens, is a significant concern for poultry health. In response, the use of medicinal plant-derived anthelmintics was proposed as a potential solution. This study observed the effectiveness of a single, graded dose of the ethanol extract of , L.

Most poultry farming that has been conducted by smallholders in Thailand are free-range and housing systems, which have risks of parasitic infection from the environment, particularly from tapeworms in the genus Raillietina and trematodes in the family Echinostomatidae. These have become important health problems in the poultry industry, causing low feed conversion ratios and leading to the loss of economic value. Our objective was to develop and validate a molecular technique based on duplex loop-mediated isothermal amplification (LAMP) together with lateral flow dipstick (LFD) assay for discriminating the infections between the genus Raillietina (R.
