Campylobacter concisus, a member of the human’s oral microflora, is Gram-negative, fastidious, microaerophilic bacterium. However, it debatable whether should be recognised as commensal human cavity, or an opportunistic pathogen has been linked to and gastrointestinal infections. But there no doubt that its biofilm-forming capacity enhanced survival mechanism pathogen. Hence, through our invest...
Food allergy, other adverse immune responses to foods, inflammatory bowel disease, and eosinophilic esophagitis have become increasingly common in the last 30 years. It has been proposed in the "hygiene hypothesis" that dysregulated immune responses to environmental microbial stimuli may modify the balance between tolerance and sensitization in some patients. Of the pattern recognition receptor...
Listeria monocytogenes is one of several enteric microbes that is acquired orally, invades the gastric mucosa, and then disseminates to peripheral tissues to cause systemic disease in humans. Intravenous (i.v.) inoculation of mice with L. monocytogenes has been the most widely-used small animal model of listeriosis over the past few decades. The infection is highly reproducible and has been inv...
Human-associated microbial communities vary across individuals: possible contributing factors include (genetic) relatedness, diet, and age. However, our surroundings, including individuals with whom we interact, also likely shape our microbial communities. To quantify this microbial exchange, we surveyed fecal, oral, and skin microbiota from 60 families (spousal units with children, dogs, both,...
مقدمه: سینوزیت مزمن، یک مشکل درمانی است که در حدود 15% از افراد جامعه به آن مبتلا هستند. این بیماری با مصرف طولانی مدت آنتی بیوتیک های مختلف و دوره های بهبودی نسبی و موقت بیماری و عود مجدد، گذشته از هزینه های بالای تجویز آنتی بیوتیک های وسیع الطیف و همچنین عوارض جانبی آنها باعث تشکیل سوش های مقاوم به درمان های رایج می شود. علت اصلی این مسئله عدم شناخت کافی از سوش های عامل بیماری و درمان crs است...
Stress is defined as a physical, mental or emotional response to events that causes bodily or mental tension. Every organ in the human body is affected by various types of diseases like infection caused by microbes, immunological, metabolic, endocrinal disturbances etc., Etiopathogenesis of many diseases are discovered and managed at any early stage, still some diseases are considered as idiopa...
Microorganisms play an unequivocal role in infecting root canal system. Endodontic infections are different from the other oral infections in the fact that they occur in an environment which is closed to begin with since the root canal system is an enclosed one, surrounded by hard tissues all around [1,2]. Most of the diseases of dental pulp and periradicular tissues are associated with microor...
Discriminating between commensal and pathogenic states of opportunistic pathogens is critical for host mucosal defense and homeostasis. The opportunistic human fungal pathogen Candida albicans is also a constituent of the normal oral flora and grows either as yeasts or hyphae. We demonstrate that oral epithelial cells orchestrate an innate response to C. albicans via NF-κB and a biphasic MAPK r...
