R espiratory infections by the opportunistic pathogen Pseudomonas aeruginosa in immunocompromised patients or in patients with cystic fibrosis (CF) are the result of unique conditions that allow this Gram-negative bacterium to colonize the lung. This interaction between the pathogen and host leads to responses in both cells that ultimately lead to severe lung degeneration in individuals with CF...

The triphosphate tunnel metalloenzyme (TTM) superfamily represents a group of enzymes that is characterized by their ability to hydrolyze a range of tripolyphosphate substrates. Arabidopsis (Arabidopsis thaliana) encodes three TTM genes, AtTTM1, AtTTM2, and AtTTM3. Although AtTTM3 has previously been reported to have tripolyphosphatase activity, recombinantly expressed AtTTM2 unexpectedly exhib...

Reconstruction of host-pathogen protein interaction networks is of great significance to reveal the underlying microbic pathogenesis. However, the current experimentally-derived networks are generally small and should be augmented by computational methods for less-biased biological inference. From the point of view of computational modelling, data scarcity, data unavailability and negative data...

Plant WRKY transcription factors can function as either positive or negative regulators of plant basal disease resistance. Arabidopsis WRKY48 is induced by mechanical and/or osmotic stress due to infiltration and pathogen infection and, therefore, may play a role in plant defense responses. WRKY48 is localized to the nucleus, recognizes the TTGACC W-box sequence with a high affinity in vitro an...

BACKGROUND Merkel cell carcinomas (MCCs), clinically aggressive neuroendocrine skin cancers, are divided into Merkel cell polyomavirus (MCPyV)-positive and -negative tumors, which show different clinicopathological features and may develop through different mechanisms of carcinogenesis. Aberrant expression of activation-induced cytidine deaminase (AID) as a genomic modulator was demonstrated th...

Rapid and accurate identification of mastitis pathogens is important for disease control. Bacterial culture and isolate identification is considered the gold-standard in mastitis diagnosis but is time-consuming and results in many culture-negative samples. Identification of mastitis pathogens by PCR has been proposed as a fast and sensitive alternative to bacterial culture. The results of bacte...

Sphingomonas paucimobilis is an emerging gram-negative aerobic bacterium, generally causing infections in immunocompromised patients. Few data are available about peritonitis peritoneal dialysis due to this pathogen. The clinical courses and outcomes of variable, with a high frequency catheter removal withdrawal. No guidelines for the treatment related peritonitis, its role as pathogen, antibio...

The interaction of plants with bacterial pathogens involves the manipulation of programmed cell death (PCD) pathways. During a resistance interaction PCD is induced in a process termed the hypersensitive response (HR) which may function to limit pathogen spread. In a susceptible plant-pathogen interactions, the pathogen both inhibits and/or induces host PCD depending on the infection stage and ...

die-back disease caused by paecilomyces variotti is one of the most destructive diseases of pistachio in iran. in this study, genetic diversity of paecilomyces variotti isolates was investigated with ssr marker, using six primers pairs. sampling was done from pistachio gardens in different geographical zones of kerman province during summer 2013. various fungal isolates were isolated from infec...
