Researchers have unveiled the evolutionary origin of the different chromosomal architectures found in three species of Agrobacterium.
University and government researchers have linked a bacteria species commonly found in sheep to human illness, a report in a U.S.
Researchers at North Carolina State University and the Centers for Disease Control and Prevention have produced the first link between a species of bacteria most commonly found in sheep and human illness.
Bacteria that can cause serious heart disease in humans are being spread by rat fleas, sparking concern that the infections could become a bigger problem in humans.
By Choi, Hyong Woo Lee, Byung Gil; Kim, Nak Hyun; Park, Yong; Lim, Chae Woo; Song, Hyun Kyu; Hwang, Byung Kook Plants elaborate a vast array of enzymes that synthesize defensive secondary metabolites in response to pathogen attack.
By Dan, Yinghui Abstract Browning and necrosis of transformed cells/ tissues, and difficulty to regenerate transgenic plants from the transformed cells/tissues (recalcitrance) are common in Agrobacterium-mediated transformation process in many plant species.
By Sussex, Ian M One of the stellar achievements of twentieth century plant biologywas the genetic transformation of somatic cells enabling the regeneration of whole plants that were stably transformed and capable of transmitting the inserted genetic material to subsequent generations.
Research carried out with the participation of the University of Navarra has shown how a determinate molecule helps an important pathogen, Brucella abortus, escape destruction within the cells charged with eliminating infectious agents (macrophages). This research has been published in Nature Immunology scientific magazine.
Bartonella henselae is a proteobacterium that can cause bacteremia, endocarditis, bacillary angiomatosis, and peliosis hepatis. It is a causative agent of cat-scratch disease which occurs after a cat bite or scratch. The disease is characterized by swelling of the lymph nodes and fever. B. henselae can cause Peliosis hepatic which may develop with cutaneous bacillary angiomatosis or bacteremia. Those with peliosis hepatitis can have gastrointestinal symptoms, fever, chills, and an enlarged...
Agrobacterium tumefaciens is the causal agent of crown gall disease (the formation of tumours) in over 140 species of dicot. It is rod shaped. Symptoms are caused by the insertion of a small segment of DNA into the plant cell. It is an alphaproteobacterium of the family Rhizobiaceae which includes the nitrogen fixing legume symbionts. They are pathogenic and provide no benefit to the plant. It also affects a wide variety of plants. In an economical sense it affects walnuts, grape vines,...
