Infection in Drosophila simulans with the endocellular symbiont Wolbachia pipientis results in egg lethality caused by failure to properly initiate diploid development (cytoplasmic incompatibility, CI). The relationship between Wolbachia infection and reproductive factors influencing male fitness has not been well examined. Here we compare infected and uninfected strains of D. simulans for (1) ...
Wolbachia pipientis is a bacterium that induces cytoplasmic incompatibility (CI), the phenomenon in which infected males are reproductively incompatible with uninfected females. CI spreads in a population of hosts because it reduces the fitness of uninfected females relative to infected females. CI encompasses two steps: modification (mod) of sperm of infected males and rescuing (resc) of these...
زمینه و اهداف: باکتری داخل سلولی wolbachia pipientis از جمله باکتری های ریکتزیایی است. ژن این باکتری در حشرات به صورت مادرزادی به ارث می رسد و می تواند عامل ایجاد ناسازگاری های سیتوپلاسمی باشد. این باکتری به طور بالقوه می تواند در دستکاری های ژنتیکی جمعیت و کنترل ناقلین برخی بیماری ها مفید باشد. در این مطالعه w. pipientis با استفاده از روشpcr در پشه خاکی گونه فلبوتوموس پاپاتاسی، ناقل بیماری لیش...
The Rickettsiaceae is a family of intracellular bacterial symbionts that includes both vertically transmitted parasites that spread by manipulating the reproduction of their host (Wolbachia in arthropods) and horizontally transmitted parasites (represented by Cowdria ruminantium), and mutualists (Wolbachia pipientis in nematode worms). We have investigated the nature of natural selection acting...
Wolbachia pipientis are obligate intracellular bacteria commonly found in many arthropods. They can induce various reproductive alterations in hosts, including cytoplasmic incompatibility, male-killing, feminization, and parthenogenetic development, and can provide host protection against some viruses and other pathogens. Wolbachia differ from many other primary endosymbionts in arthropods beca...
