The bacterium that causes cucurbit yellow vine disease (CYVD) has been placed in the species Serratia marcescens based on 16S rDNA and groE sequence analysis. However, phenotypic comparison of the organism with S. marcescens strains isolated from a variety of ecological niches showed significant heterogeneity. In this study, we compared the genomic DNA of S. marcescens strains from different niches as well as type strains of other Serratia spp. through repetitive elements-based polymerase chain reaction (rep-PCR) and DNA-DNA hybridization. With the former, CYVD strains showed identical banding

Abstract Opportunistic pathogens are environmental microbes that are generally harmless and only occasionally cause disease. Unlike obligate pathogens, the growth and survival of opportunistic pathogens does not rely on host infection or transmission. Their versatile lifestyles make it challenging to decipher how and why virulence has evolved in opportunistic pathogens.
