To investigate the prevalence and cyst burden of Giardia duodenalis as well as the genetic identity and possible zoonotic potential of isolates in canine faeces left on soil, a total of 143 freshly passed faecal specimens were collected in four different green urban areas and examined by Real-time PCR. Overall, 30.8% of faeces from different dogs that defecated in urban areas were found to harbour Giardia cysts, with single area positivity proportions ranging from 4.2% to 47.8%; significant (P < 0.05) and highly significant (P < 0.01) differences were found in the prevalence among different areas investigated. The number of cysts ranged from 2 to 1428 per gram of faeces. Results emphasize that a high risk of clog-to-dog Giardia transmission may occur in public areas where high quantities of faeces from infected dogs are daily left to cumulate on the ground. Results suggest there is a low risk for zoonotic transmission of Giardia: only 0.6% of canine faeces contaminating urban areas were carrying subgenotype A1, which is considered as the most potentially transmissible to humans.
