We studied the microbial flora in decomposing mangrove leaves in relation to changes in nitrogen and tannin levels, and in penaeid prawn assemblages. Senescent leaves of two mangrove species (Rhizophora apiculata and Avicennia marina) kept in nylon bags, were separately immersed for 80 days in five tanks full of mangrove water. A known amount of decomposing leaves was collected every ten days f...

The Lactobacillus (Doderlein's bacillus) (Wilson and Miles, 1964) had been regarded as the preponderant micro-organism in the vagina, at least after puberty. During the 1960s a re-examination of the microbiology of the vagina was prompted by the widespread use of potent antibacterial agents and of oral contraceptives (Krupp and St. Romain, 1960; Morris and Morris, 1967; Morris, 1969). During th...

To assess if (1-->3)-beta-D-glucan, a microbial cell wall agent normally present in pollen, has the ability to produce pollenlike response, sensitive persons received a nasal deposition of two doses of (1-->3)-beta-D-glucan. The percentage of eosinophils and amount of eotaxin were measured in nasal lavage 30 minutes and 24 hours after challenge. No effect could be demonstrated. The absence of a...

abstract introduction. cardiovascular disease is the most common cause of death in developed counteries and it’s morbidity and mortality is also increasing in asia. hypertension, hyperlipidemia and smoking are majore risk factors of atherosclerosis. in recent years infectious agents such as clamidia pneumoniae, helicobacter pylori and dental flora infections seems to be effective in development...

Allergic and autoimmune diseases had been attributed to lack of exposure to biodiversity, an important factor in regulating immune homeostasis in a healthy host. We posit that the microbiome of healthy dairy farmers (DF) will be richer than non-farmers (NF) living in urban settings due to exposure to a greater biodiversity in the dairy environment. However, no studies have investigated the rela...

The notion that the mucosal immune system maintains a tolerogenic response to harmless Ags while continually being challenged with microbial products seems an enigma. The aim of this study was to unravel mechanisms that are involved in regulating the development of tolerance under constant microbial pressure. The tolerogenic response to Ags administered via the nasal mucosa is dependent on the ...

OBJECTIVES/HYPOTHESIS Microbial biofilms have been implicated in the pathogenesis of chronic rhinosinusitis with nasal polyposis (CRSwNP). Although biofilms are characterized by an extremely high resistance against chemical and physical agents, low-frequency ultrasound (LFU) treatment has been suspected to be an efficient and safe method for biofilm disruption. STUDY DESIGN Basic science expe...

Background. The objective of this prospective study was to evaluate the clinical profile, microbiological flora and radiological features in primary atrophic rhinitis patients and to identify their association with the etiology of primary atrophic rhinitis. Study design. Prospective case study. Materials and methods. Patients with primary atrophic rhinitis over a two years period were included ...

OBJECTIVES The majority of nosocomial Staphylococcus aureus infections originate from the patients' own flora, with nasal carriage of S. aureus before surgical procedures being a risk factor for subsequent infection. The objective of this review was to assess whether intranasal mupirocin treatment of nasal S. aureus carriers before surgery results in a reduction of the post-operative S. aureus ...
