BACKGROUND Infection with Ornithobilharzia turkestanicum has been reported in a wide range of animals worldwide. This study was undertaken to assess the utility of polymerase chain reaction (PCR), for detecting the infection with O. turkestanicum larvae stages in Lymnaea gedrosiana. METHODS A total of 6,759 Lymnaeidae snails were collected from six aquatic habitats in West Azarbaijan, northwe...

METHODS In this cross-sectional study, all 35-70 years old people living in Khameneh, a city in East Azarbaijan, Iran were invited to take part in the pilot phase of the AZAR Cohort Study. A total of...

This study aimed to determine biological activity and phytochemical study of Scutellaria platystegia (family Labiatae). Methanolic (MeOH) extract of aerial parts of S. platystegia and SPE fractions of methanolic extract (specially 20% and 40% methanolic fractions), growing in East-Azarbaijan province of Iran were found to have radical scavenging activity by DPPH (2, 2-diphenyl -1- pycryl hydraz...

Abstract Background Root-knot nematodes ( Meloidogyne spp.) are among the most important plant pathogens. Biological control is one of safety and effective methods for these nematodes. The aim present study was isolation identification endophytic bacteria from tomato fields in some areas Iran order to evaluate their biocontrol potential against root-knot nematode. In study, population collected...
