Gamma Proteobacteria

The most diverse class of gram-negative bacteria is Gammaproteobacteria, and it includes a number of human pathogens. For example, a large and diverse family, Pseudomonaceae, includes the genus Pseudomonas. Within this genus is the species P. aeruginosa, a pathogen responsible for diverse infections in various regions of the body.

P. aeruginosa is a strictly aerobic, nonfermenting, highly motile bacterium. It often infects wounds and burns, can be the cause of chronic urinary tract infections, and can be an important cause of respiratory infections in patients with cystic fibrosis or patients on mechanical ventilators. Infections by P. aeruginosa are often difficult to treat because the bacterium is resistant to many antibiotics and has a remarkable ability to form biofilms.

ERWINIA QUERCINA

Class:	Gamma Proteobacteria
Genus:	Erwinia
Species:	Erwinia quercina
Description:	This species is known as “Lonsdalea quercina”.It was firstly reported in Oaks at California(U.S.A) in 1967 .After that it was found in forest oaks at Spain. It was gram negative, oxidase negative, facultatively anaerobic,urease negative and also negative for nitrate reduction.
Synonyms:	Lonsdalea quercina;Brenneria quercina.
Source:	It was found near at Madrid and Segoviain in Spain and California in U.S.A .
Pathogenicity:	Brenneria quercina(Erwinia quercina)is the causal agent of "Drippy nut" disease of oaks in Quercus species(Quercus agrifolia and Quercus wislizenii) in the California (U.S.A). It is also responsible for "bleeding bark cankers and bacterial ooze on leaf buds" on Quercus pyrenaica and Quercus ilex in Spain.
