The microbiome plays a crucial role in controlling viral infections like the Human Papillomavirus. Getting infected by HPV is not always necessary or sufficient for progression of cervical cancer. According to many kinds research, it was shown that presence papillomavirus infection connected abundance Lactobacilli and L. gasseri. Besides some research data suggests an association cervicovaginal...

Arabidopsis (Arabidopsis thaliana) penetration (PEN) genes quantitatively contribute to the execution of different forms of plant immunity upon challenge with diverse leaf pathogens. PEN3 encodes a plasma membrane-resident pleiotropic drug resistance-type ATP-binding cassette transporter and is thought to act in a pathogen-inducible and PEN2 myrosinase-dependent metabolic pathway in extracellul...

In the present era of ever-increasing antibiotic resistance and increasingly complex and immunosuppressed patient populations, physicians and scientists are seeking novel approaches to battle difficult infectious disease conditions. Development of a serious infection implies a failure of innate immune capabilities in the patient, and one may consider whether pharmacological strategies exist to ...

background staphylococcus aureus is a common pathogen in hospitals and communities. antibiotic resistance is a major public health problem. objectives the aim of this study was the determination of antimicrobial susceptibility patterns and to perform molecular detection of macrolide and lincosamide-resistance genes in clinical s. aureus isolates from kerman, iran. conclusions a high prevalence ...

Plants cope with pathogen attacks by using mechanisms of resistance that rely both on preformed protective defenses and on inducible defenses. The latter are the most well studied, and progress is being made in determining which induced responses are responsible for limiting pathogen growth. Many plant-pathogen interactions are accompanied by plant cell death. Recent evidence suggests that this...

A model sentinel plant (phytosensor) capable of signaling pathogen attack in the field was obtained by transformation with a construct containing the green fluorescent protein (GFP) as a reporter gene, driven by the promoter of gn1 , a tobacco b-1,3glucanase gene. This is a first step towards the creation of sentinel plants for early disease diagnostics with an integral real-time, fluorescent-b...

Plants are continuously exposed to myriad pathogen stresses. However, the molecular mechanisms by which these stress signals are perceived and transduced are poorly understood. In this study, the maize gene GRMZM2G315431 was identified to be highly inducible by Rhizoctonia solani infection, suggesting that the promoter of GRMZM2G315431 (pGRMZM2G315431) might contain a specific cis-acting elemen...

RNA interference, mediated by small interfering RNAs (siRNAs), is a conserved regulatory process that has evolved as an antiviral defense mechanism in plants and animals. It is not known whether host cells also use siRNAs as an antibacterial defense mechanism in eukaryotes. Here, we report the discovery of an endogenous siRNA, nat-siRNAATGB2, that is specifically induced by the bacterial pathog...
