Toxoplasma gondii is one of the most common zoonotic parasitic diseases in human and warm-blooded animals worldwide. Birds are one of important intermediate hosts of T. gondii. The aim of this study is molecular detection of T. gondii in the house sparrow by LAMP and PCR methods in Tehran, Iran. A total 200 sparrows were captured in different regions of Tehran. DNA was extracted from tissue samples of each sparrow. LAMP and conventional PCR assays were carried out with a set of primers to detect the 529 bp fragment of T. gondii. LAMP and PCR were detected T. gondii from 17 (8.5 %) and 15 (7.5 %) of 200 sparrows respectively. These results indicated that sensitivity of LAMP was higher than conventional PCR. In our knowledge, this study is the first report of detection of T. gondii by LAMP method in bird hosts. Also, these findings provided an insight into epidemiological pattern of T. gondii infection in sparrow in Iran.
