“…Whereas, Pseudomonas fragi was isolated from lettuce (Edelman and Lin, 2014). Pseudomonas aeruginosa, a common opportunistic bacterium between humans and plants was isolated from diferent sources such as rhizosphere of corn (Tahmasebi et al, 2014) and tobacco leaf in China (Yu, 2008). Another important species was Pseudomonas fulva, a clinical isolate which has been reported mostly from aquatic environments including rice seed and fennel plants (Edelman and Lin, 2014).…”

In order to determine the factors of decay and sourness of fig fruits, in the summer of 2016-17, 60 leaf, fruit and stem samples from different regions of Tehran, Varamin (Qal'e No), Mazandaran (Amol, Noor and Sari), Lorestan from Iran and a branch of fig fruit sample from Italy were collected. We obtained 30 isolates from the sample. The pathogenicity of 30 isolates were confirmed by artificially inoculation using fig fruits. They were also characterized based on key phenotypic traits. All 30 isolates showed hypersensitivity reaction to tobacco, pelargonium and did not show pathogenicity to potato tubers. 16S rRNA gene of the 10 representative isolates were sequenced. Ten isolates were identified as Stenotrophomonas maltophilia, Pseudomonas aeruginosa, Pseudomonas fulva, Brevibacterium linens, Pseudomonas fragi, Bacillus licheniformis, Bacillus paralicheniformis and Bacillus cereus based on the determined sequences. None of the isolates caused fruit rot but typical disease symptoms were observed on fig leaves and fruits. This is the first report of the presence of pathogenic bacteria on fig trees in Iran.

“…P. aeruginosa-mediated fruit rot disease has occurred in India during round melon cultivation [337]. Similarly, P. aeruginosa was identified as the causal agent of bacterial leaf spots in tobacco seedlings in China [372]. Furthermore, this organism has caused collar rot in lily and root rot in ginseng and inhibited maize seed germination [338][339][340].…”

Pseudomonas aeruginosa is one of the most versatile bacteria with renowned pathogenicity and extensive drug resistance. The diverse habitats of this bacterium include fresh, saline and drainage waters, soil, moist surfaces, taps, showerheads, pipelines, medical implants, nematodes, insects, plants, animals, birds and humans. The arsenal of virulence factors produced by P. aeruginosa includes pyocyanin, rhamnolipids, siderophores, lytic enzymes, toxins and polysaccharides. All these virulent elements coupled with intrinsic, adaptive and acquired antibiotic resistance facilitate persistent colonization and lethal infections in different hosts. To date, treating pulmonary diseases remains complicated due to the chronic secondary infections triggered by hospital-acquired P. aeruginosa. On the contrary, this bacterium can improve plant growth by suppressing phytopathogens and insects. Notably, P. aeruginosa is one of the very few bacteria capable of trans-kingdom transmission and infection. Transfer of P. aeruginosa strains from plant materials to hospital wards, animals to humans, and humans to their pets occurs relatively often. Recently, we have identified that plant-associated P. aeruginosa strains could be pathologically similar to clinical isolates. In this review, we have highlighted the genomic and metabolic factors that facilitate the dominance of P. aeruginosa across different biological kingdoms and the varying roles of this bacterium in plant and human health.

“…E. mallotivora was first reported as the causal agent of bacterial leaf spot in Mallotus japonicas in Japan (2). In recent studies that included phenotypic observations, biochemical analysis, and genotypic information, E. mallotivora was identified as a close relative of E. papayae and the causal agent of the papaya dieback disease in Malaysia (3, 4). Thus, it is of great interest to uncover the genome sequence of the isolate obtained from papaya trees infected with dieback.…”
