a new entomopathogenic nematode, steinernema anatoliense n. sp. (rhabditida: steinernematidae), from turkey.a description is given of steinernema anatoliense n. sp. (rhabditida: steinernematidae), an entomopathogenic nematode isolated from soil samples collected in the locality of kars, east anatolia, turkey. cross-hybridisation, morphological and molecular studies (rflp analysis) indicated the distinctness of s. anatoliense n. sp. from other steinernema species. diagnostic characters include: body length of third-stage infective juvenile (507-580 microm); lateral field pattern with 6-8 longitudinal r ...200312878850
ecological characterization of steinernema anatoliense (rhabditida: steinernematidae).our study describes the basic ecological characteristics of the entomopathogenic nematode steinernema anatoliense including its response to temperature, moisture, and host range. the effect of temperature and soil moisture on the infection of galleria mellonella larvae by s. anatoliense was determined. the temperature range for infectivity was greater than that for development. the optimal temperature for infection and development was 25 degrees c. although s. anatoliense infected the hosts at 1 ...200616564537
the xnp1 p2-like tail synthesis gene cluster encodes xenorhabdicin and is required for interspecies competition.xenorhabdus nematophila, the mutualistic bacterium of the nematode steinernema carpocapsae, produces the r-type bacteriocin called xenorhabdicin that is thought to confer a competitive advantage for growth in the insect host. we have identified a p2-like tail synthesis gene cluster (xnp1) that was required for xenorhabdicin production. the xnp1 genes were expressed constitutively during growth and were induced by mitomycin c. deletion of either the sheath (xnps1) or fiber (xnph1) genes eliminate ...201121602326
