the recognition of seasonal patterns in infectious disease occurrence dates back at least as far as the hippocratic era, but the mechanisms underlying these fluctuations remain poorly understood. many classes of mechanistic hypotheses have been proposed to explain seasonality of various directly transmitted diseases, including at least the following; human activity, seasonal variability in huma...

conclusions finally, it can be suggested that the extracts of this plant be applied as antimicrobial agents against these pathogens, particularly in biofilm forms. results the results showed that the a. sativum l. extract discs did not have any zone of inhibition for the tested bacteria. however, the mic values of a. sativum l. extracts (0.078 - 2.5 mg/ml) confirmed the high ability of these ex...

different species of streptomyces are common in most types of soil. some certain species are plant pathogenic especially on potato. this study was conducted to evaluate genetic diversity among some local streptomyces spp. strains isolated from soil and infected tubers in potato farms in northwest of iran. repetitive dna elements (box, eric and rep) as genetic markers were used for diversity stu...
