Pathogenicity of bacterium, Xenorhabdus nematophila isolated from entomopathogenic nematode (Steinernema carpocapsae) and its secretion against Galleria mellonella larvae.
The entomopathogenic bacterium, Xenorhabdus nematophila was isolated from the hemolymph of Galleria mellonella infected with Steinernema carpocapsae. The bacterial cells and its metabolic secretions have been found lethal to the Galleria larvae. Toxic secretion in broth caused 95% mortality within 4 d of application whereas the bacterial cells caused 93% mortality after 6 d. When filter and san...
متن کاملIsolation and Identification of Photorhabdus Luminescens an Insect Pathogenic Bacteria Associated with Entomopathogenic Nematode
Photorhabdus luminescens is a gram negative symbiotic bacterium belonging to the family Enterobacteriaceae, and is a lethal pathogen of insects. It lives in the gut of an entomopathogenic nematode of the family Heterorhabditidae. When the nematode infects an insect, P. luminescensis released into the blood stream and rapidly kills the insect host by producing toxins. So the present study was ca...
متن کاملResponses of the entomopathogenic nematode, Steinernema riobrave to its insect hosts, Galleria mellonella and Tenebrio molitor.
Potential hosts for infective juveniles of entomopathogenic nematodes can vary considerably in quality based on the characteristics of the host species/stage, physiological status (e.g. stress, feeding on toxins), and infection status (heterospecific or conspecific infection). In this study, we investigated responses of the entomopathogenic nematode Steinernema riobrave to hosts (Galleria mello...
متن کاملSome effects of x-irradiation on larvae of Galleria mellonella.
During the summer of 1965, the fungus Spicaria rileyi was frequently associated with dead Pseudoplusia includens larvae on various crops in southeastern Alabama. Since this insect, sometimes referred to as the false looper, has become of increasing economic importance in Alabama (Canerday, J. Econ. Entomol., in press, 1966), the pathogenicity and potential control value of S. rileyi for P. k&de...
متن کاملThe involvement of protein kinase A in the immune response of Galleria mellonella larvae to bacteria.
The role of protein kinase A (PKA) in the humoral immune response of the greater wax moth Galleria mellonella larvae to live gram-positive bacteria Micrococcus lysodeikticus and gram-negative bacteria Escherichia coli was investigated. The immune challenge of larvae with both kinds of bacteria caused an increase in fat body PKA activity depending on the injected bacteria. Gram-positive M. lysod...
