During the period from 1997 to 1998, samples of wheat leaves were collected from different wheat farms in Fars and Kohgiluyeh & Boyrahmad provinces to identify the causal agent of wheat leaf blight. On the basis of LOPAT tests and production of fluorescent pigment on KB medium, 181 bacterial isolates were recovered from the samples. Based on biochemical, physiological and pathogenicity tests, t...
Bacterial wilt is a soil-borne disease that causes severe damage in ginger-growing regions of Japan (eight prefectures the Shikoku, Kyushu, and Honshu regions). Because pathogen Ralstonia pseudosolanacearum usually lives deeper soil infects host plants via roots, it not easy to eliminate even with chemical pesticides (such as fumigants). In our previous study, we found anaerobic disinfestation ...
The aim of this study was to conduct an epidemiological and laboratory surveillance of Influenza-Like Illnesses (ILI) in Polish Armed Forces, civilian military personnel and their families in 2011/2012 epidemic season, under the United States Department of Defense-Global Emerging Infections Surveillance and Response System (DoD-GEIS). ILI incidence data were analyzed in relation to age, gender,...
Bacteria Etiological Agents Causing Lower Respiratory Tract Infections and Their Resistance Patterns
Background: Lower respiratory tract infections (LTRIs) are among the most common infectious diseases with potential life-threatening complications. Methods: The study consisted of 426 patients with suspected LTRIs from mid and far western region of Nepal between September 2011 and July 2014. The specimens were collected and processed according to the standard microbiological methods at the Cent...
The contribution of CCR6 and phagocyte recruitment to the initiation of T cell responses to a local pathogen is unclear. CD4 T cell activation to an injected soluble antigen occurred rapidly and was completely CCR6-independent. In marked contrast, the tempo of pathogen-specific CD4 T cell activation depended on whether the antigen was secreted or cell-associated. Furthermore, lymph node pathoge...
The use of plant protoplast transient expression system has facilitated the discovery and dissection of many signal transduction pathways in response to hormones, metabolites, and stresses. Recently, Arabidopsis protoplasts also have been used successfully to study plant innate immune responses triggered by pathogen-derived elicitors. Here, we describe the detailed protocols for studying innate...
Previous studies in lower termites revealed unexpected synergies between nicotinoid insecticides and fungal entomopathogens. The present study investigated molecular mechanisms of nicotinoid-pathogen synergy in the lower termite Reticulitermes flavipes, using the nicotinoid, imidacloprid, in combination with fungal and bacterial entomopathogens. Particular focus was placed on metatranscriptome ...
In vertebrates, variability at genes of the Major Histocompatibility Complex (MHC) represents an important adaptation for pathogen resistance, whereby high allelic diversity confers resistance to a greater number of pathogens. Pathogens can maintain diversifying selection pressure on their host's immune system that can vary in intensity based on pathogen richness, pathogen virulence, and length...
Symbiotic bacteria may dampen the impacts of infectious diseases on hosts by inhibiting pathogen growth. However, our understanding of the generality of pathogen inhibition by different bacterial taxa across pathogen genotypes and environmental conditions is limited. Bacterial inhibitory properties are of particular interest for the amphibian-killing fungal pathogens (Batrachochytrium dendrobat...
