Entry of Rickettsia tsutsugamushi into polymorphonuclear leukocytes.
Factors involved in the phagocytosis and entry into polymorphonuclear leukocytes (PMNs) of Rickettsia tsutsugamushi were studied by electron microscopy. R. tsutsugamushi propagated in baby hamster kidney cell cultures was incubated with guinea pig peritoneal PMNs in vitro at 35 degrees C. Structurally intact and degenerating rickettsiae were found in phagosomes, but only intact rickettsiae esca...
متن کاملEffect of immune serum on infectivity of Rickettsia tsutsugamushi.
Hyperimmune antirickettsial serum was shown to prevent the attachment/penetration stage of Rickettsia tsutsugamushi infection of suspended chicken cells. The extent of the inhibition depended on the serum concentration but not on the presence of complement. The neutralizing activity was reduced by prior adsorption of immune serum with staphylococcal protein A or with intact rickettsiae but was ...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولComparative studies on molecular techniques for detecting Rickettsia tsutsugamushi in Leptotrombidium deliense and mice
In order to establish the most sensitive and specific method in the detection of Rickettsia tsutsugamushi in Leptotrombidium deliense , mice and patients, a comparative study on DNA extraction, PCR, hybridization and PCR-hybridization was conducted. The results showed that the sensitivity of PCR-hybridization was 10 times higher than that of PCR and 1000 times higher than that of hybridization....
متن کاملAnalysis of antigenic characteristics of Rickettsia tsutsugamushi Boryong strain and antigenic heterogeneity of Rickettsia tsutsugamushi using monoclonal antibodies.
Twenty-four monoclonal antibodies were produced by immunizing BALB/c mice with Rickettsia tsutsugamushi Boryong strain and used for the analysis of antigenic characteristics of R.tsutsugamushi Boryong strain and antigenic heterogeneity of R.tsutsugamushi by indirect immunofluorescent(IF) test. R. tsutsugamushi Kato, Karp, Gilliam, TA686, TA716, TA763, TC586, TH1817, and Boryong were used for th...
