Toxoplasma gondii 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 T. gondii oocysts or via 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 (Gallus domesticus) raised on the ground constitute a potential source of T. gondii. 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. Toxoplasma gondii 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. DNA extracted from 5 out of 50 tissue samples was positive for both genes by qPCR amplification. The 10% prevalence of Toxoplasma infection found in commercial free-range chickens raises public health issues.

A study was carried out to detect and identify the presence of coccidia oocysts in the faeces of village chicken from the district of Pasir Putih, Kelantan, West Malaysia. A total of 135 fecal samples were collected from 15 areas in the Pasir PutihDistrict. The faecal samples were examined by direct smear method (qualitative study). A pinch of the faeces was put onto the glassslide with 1-2 drops of normal saline and cover slip, which was then observed under the compound microscope to detect thecoccidia oocysts. The presence of coccidia oocyst was then identified by its size and shape. Results showed that ten out of 135 samples were positive for coccidia oocysts, and classified as Eimeria maxima and Eimeria mitis, both of which are from two locations at Kampung Chap Banir, Pasir Putih, Kelantan. The remaining 125 samples were observed to be negative. This may suggest that the chickens reared in the backyard (extensive)are less susceptible to the coccidia infection due to their environment with lower stocking density (mostly free ranging chicken), and no damp/wet litter as bedding which canfacilitate sporulation of the coccicia oocyst thereby spreading the infection. Further studies need to be done to elucididate other factors which may affect coccidial infections in free range chicken such as the availability of medications in feed or genetic hardiness and tolerance to field infections. The localvillage chicken industry is an up and coming facet of the poultry industry and needs concerted efforts to boost it.
