| interactions within susceptible hosts drive establishment of genetically distinct variants of an insect-borne pathogen. | coinfections are common, leading to pathogen interactions during transmission and establishment in a host. however, few studies have tested the relative strengths of pathogen interactions in vectors and hosts that determine the outcome of infection. we tested interactions between two genetically distinct variants of the mealybug-transmitted grapevine leafroll-associated virus 3. the transmission efficiency of each variant in single variant inoculations by two vector species was determined. the e ... | 2015 | 26470292 |
| Molecular and histological characterisation of primary (ß-proteobacteria) and secondary (?-proteobacteria) endosymbionts of three species of mealybugs (Pseudococcus longispinus, Pseudococcus calceolariae, Pseudococcus viburni) (Pseudococcidae, Hemiptera) and prediction of interactions of their GroEL homologs with Grape Leaf Roll-associated Virus-3. | Microscopic localization of endosymbiotic bacteria in three species of mealybug (Pseudococcus longispinus, long-tailed mealybug; Pseudococcus calceolariae, citrophilus mealybug; and Pseudococcus. viburni, obscure mealybug) showed these organisms were confined to bacteriocyte cells within a bacteriome centrally located within the haemocoel. Two species of bacteria were present, with the secondary endosymbiont, in all cases, living within the primary endosymbiont. DNA from the dissected bacteriome ... | 2011 | 22156418 |
