Afforestation efforts have resulted in extensive plantations of either native or non-native conifers, which in many regions has led to the spread of those conifers into surrounding natural vegetation. This process of species colonization can trigger profound changes in both community dynamics and ecosystem processes. Our study disentangled the complexity of a process of colonization in a hetero...

actinomycosis is an anaerobic infection that involves the craniofacial region and its colonization has rarely been reported in the developmental odontogenic cysts. in the present report, a case of odontogenic keratocyst (which is now called keratocystic odontogenic tumor) with the colonization of actinomyces is introduced and its significance is discussed.

Animal epithelial tissue becomes reproducibly colonized by specific environmental bacteria. The bacteria (microbiota) perform critical functions for the host's tissue development, immune system development, and nutrition; yet the processes by which bacterial diversity in the environment is selected to assemble the correct communities in the host are unclear. To understand the molecular determin...

OBJECTIVES:Prenatal infections are one of the fundamental causes of early puerperal complications in mothers and neonates. These infections are mostly due to colonized organisms in pregnant woman's genitor-urinary system. The aim of this study was to determine the incidence of streptococcus group B (GBS) colonization in parturient women and the rate of pathogen transmission to the newborn. METH...

This study was conducted to evaluate changes in antioxidants, free proline, relative water content and determination of root colonization of four commercial wheat (Triticum aestivum L.) cultivars (Azar2, Darab2, Shiraz, and Falat) inoculated with the fungus Glomus intraradices, under four water regimes of 100, 75, 50, and 25% of field capacity in the year 2010 at the School of Agriculture, Shir...

While many virulence factors promoting Streptococcus pyogenes invasive disease have been described, specific streptococcal factors and host properties influencing asymptomatic mucosal carriage remain uncertain. To address the need for a refined model of prolonged S. pyogenes asymptomatic mucosal colonization, we have adapted a preestrogenized murine vaginal colonization model for S. pyogenes. I...

OBJECTIVE The spread of nosocomial multiresistant microorganisms is affected by compliance with infection control measures and antibiotic use. We hypothesized that "colonization pressure" (ie, the proportion of other patients colonized) also is an important variable. We studied the effect of colonization pressure, compliance with infection control measures, antibiotic use, and other previously ...
