    Abstract: Cohabitating nature of cockroach with humans is on the increase in most rural and underdeveloped areas of Cross River State including Calabar South. It is therefore important to screen the bacterial carriage of this pest because of shared ecological niche. Sticky trap method was used to capture the pest and properly identify by an Entomologist Dr O... Show More

    Abstract: An avirulent R. solanacearum strain named FJAT-1458 was isolated from living tomato vessel and it showed no toxicity to tomato, pepper and eggplant. Multilocus sequence analysis (MLSA) based on eight genes (egl, hrpB, mutS, pehA, recA, rpoA, rpoB and rpoC) and whole genome average nucleotide identity (ANI) analysis suggested that strain FJAT-1458 b...
