Pseudomonas syringae is a rod-shaped, Gram-negative bacterium with polar flagella. As a plant pathogen , it can infect a wide range of species, and exists as over 50 different pathovars , [ 2 ] all of which are available to researchers from international culture collections such as the NCPPB , ICMP , and others.
Pseudomonas syringae pv. glycinea attacks all of the above-ground parts of soybean, but symptoms are typically seen on the mid-upper canopy of leaves and pods. [5] After infection, small, water-soaked spots surrounded by a chlorotic halo appear on the leaves. The brown or black centers of these spots indicate that the tissue is dying.
Halo blight of bean is a bacterial disease caused by Pseudomonas syringae pv. phaseolicola. Halo blight’s pathogen is a gram-negative, aerobic, polar-flagellated and non-spore forming bacteria. This bacterial disease was first discovered in the early 1920s, and rapidly became the major disease of beans throughout the world.
P. syringae is a prolific plant pathogen. It exists as over 50 different pathovars, many of which demonstrate a high degree of host-plant specificity. Numerous other Pseudomonas species can act as plant pathogens, notably all of the other members of the P. syringae subgroup, but P. syringae is the most widespread and best-studied. [citation needed]
Pseudomonas infection refers to a disease caused by one of the species of the genus Pseudomonas. P. aeruginosa is a germ found in the environment and it is an opportunistic human pathogen most commonly infecting immunocompromised patients, such as those with cancer , diabetes , cystic fibrosis , [ 1 ] severe burns, AIDS , [ 2 ] or people who ...
"The symptoms of pneumonia can vary widely depending on the patient's age, other conditions, and the type of infection," Dr. Zweig added. He explained that symptoms can progress very quickly in ...
Pseudomonas syringae pv. Aesculi is a bacterium that causes bleeding canker of horse chestnut. The pathogen overwinters in the soil and can survive in the soil for about a year. [2] It is spread by water, rain, and tools that were used on the infected tree. [3] It causes lesions on the bark of the tree that can be near the base of the trunk or ...
Walking pneumonia, a lung infection caused by the bacterium Mycoplasma pneumoniae, tends to be most common among older children and adolescents but in 2024 has been rampant among young children.
