tuberculosis remains as an important socioeconomical and medical problem throughout the world and especially in iran. early and timely diagnosis of pulmonary and extrapulmonary tuberculosis is vital to initiate prompt treatment. current diagnostic methods are either slow or lack enough sensitivity or specificity. several mycobacterial antigens are involved in the complex interaction with the im...

crustacean hemocyanins represent a unique case of molecular heterogeneity among oxygen-carrying proteins. two populations of gammarus lacustris and six populations of gammarus komareki were identified and isolated from aquatic habitats of ardabil (northwest of iran). the populations were nominated based on name of isolated region. principal component analysis of morphological absolute attribute...

sarcocystis is a genus of cyst-forming parasites infecting both animals and human. this study aimed to isolate coccidian tissue cysts from muscle of infected animals by a simple method in addition to molecular identification of sarcocystis cruzi from the samples. the samples were obtained from commercial source in babol, northern iran. five grams of calf muscle was cut into 2-3 pieces in 30 ml ...

The survival strategy of Actinoplanes is fascinating from an evolutionary perspective, combining a short motile phase in an otherwise nonmotile, filamentous life cycle and the somewhat paradoxical concept of spores-normally thought of as a resting stage-that swim. In the first paper to report a molecular genetic analysis of development in Actinoplanes, the authors identify a key regulator of th...
