Phytopathogenic Characteristics of Clinical Pseudomonas Aeruginosa Isolates

Abstract

Existence of persistence ability of clinical isolates bacteria in plants, raises the question of their phytopathogenic characteristic and possibilities to cause pathological changes in the plants. The study included clinical isolates of Pseudomonas aeruginosa and their possibility to causing rot on potato tubers, slices of carrots, onion cloves, hypersensitive response (HR) on tobacco leaves and hydrolysis of starch. In the case of some isolates was observed potential symptoms of onion rot, while the other tests of phytopathogenic characteristics were negative.

Postojanje mogućnosti perzistencije kliničkih izolata bakterija u biljkama, otvara pitanje o njihovim fitopatogenim svojstvima i mogućnostima da izazovu patološke promene na biljkama. Ispitivanjima su obuhvaćeni klinički izolati Pseudomonas aeruginosa i njihova mogućnost prouzrokovanja truleži na krtolama krompira, kriškama mrkve, lukovicama crnog luka, kao i hipersenzitivne reakcije (HR) na duvanu i hidrolize skroba. Kod pojedinih izolata zabeležena je mogućnost pojave simptoma truleži glavica crnog luka, dok su ostala ispitivana fitopatogena svojstva negativna.
