We report the annotated genome sequence of the enterobacterial plant pathogen Pectobacterium atrosepticum strain 21A, isolated in Belarus from potato stem with blackleg symptoms.

BACKGROUND Clostridium chauvoei causes blackleg, an acute disease associated with high mortality in ruminants. The apparent primary port of entry is oral, during grazing on pasture contaminated by spores. Cases of blackleg can occur year after year on contaminated pastures. A method to determine the prevalence of C. chauvoei spores on pasture would be useful.The standard method for C. chauvoei ...

Integrative and conjugative elements (ICEs) play a central role in the evolution of bacterial virulence, their transmission between bacteria often leading to the acquisition of virulence factors that alter host range or aggressiveness. Much is known about the functions of the virulence determinants that ICEs harbor, but little is understood about the cryptic effects of ICEs on their host cell. ...

  Blackleg in cattle has been recognized since 1938 in Iran that mostly affects cattle in enzootic farm. Main object of this study was to prepare and formulate a concentrated potent vaccine for immunization of cattle against blackleg in Iran. Experimental concentrated blackleg vaccine was prepared according to the method described by FAO. The medium (Modified medium for production of experiment...

Clostridium chauvoei CH3 and Kad1 strains were found to cause marked changes in the blood parameters during the course of blackleg disease. These changes displayed by CH3 were found to be more marked than the local Kad1 strain. Results of changes in the haematological values in calves infected with blackleg organisms, showed an increase in RBC, PCV, Hb and the total leukocyte count. MCHC and MC...

The purpose of this study is to determine the effect vitamin C on immune system in cattle immunized against blackleg. employed 28 different breeds and genders, aged 15-20 months, bred Ardahan region. were broken down into four groups, seven each group. first group (control group) 2 ml saline, second (vitamin 5 mg/kg c, third (vaccination blackleg vaccine, fourth (vaccine-vitamin Blackleg vaccin...

Proteins containing valine-glutamine (VQ) motifs play important roles in plant growth and development as well defense responses to both abiotic biotic stresses. Blackleg disease, which is caused by Leptosphaeria maculans, the most disease canola (Brassica napus) worldwide; however, identification of Brassica napus VQs their functions response blackleg have not yet been reported. In this study, ...

in all biological systems growth is defined as increase of chemical compounds. bacteria can achieve to balanced growth if they are growing in a medium, which are completely adapted to it. clostridium chauvoei, (clostridium feseri) is an anaerobic, spore forming, motile, and polymorph bacteria, which its size varies from 0.5-1 to 3-8 micron and could be observed as individual bacterium, diplo, a...

Canola (Brassica napus L. and B. rapa L.), is one of the major oilseed crops grown worldwide. With significant expansion of acreage sown to canola during the past two decades, concern about blackleg, the most serious disease of canola, has increased (3,4). Blackleg disease is caused by Leptosphaeria maculans (Desmaz.) Ces. & De Not. (anamorph: Phoma lingam (Tode:Fr.) Desmaz.). The pathogen can ...

Dickeya chrysanthemi is well known as a plant pathogen that caused major blackleg in the European potato industry in the 1990s. D. chrysanthemi strain L11 was discovered in a recreational lake in Malaysia. Here, we present its draft genome sequence.
