Confocal laser endomicroscopy is a new imaging modality for recognition of intramucosal bacteria in inflammatory bowel disease in vivo.

2011

International audience; BACKGROUND AND OBJECTIVES: Interaction of bacteria with the immune system within the intestinal mucosa plays a key role in the pathogenesis of inflammatory bowel disease (IBD). The aim of the current study was to develop a fluorescein-aided confocal laser endomicroscopy (CLE) method to visualise intramucosal enteric bacteria in vivo and to determine the involved mucosal area in the colon and ileum in patients with ulcerative colitis (UC) and Crohn's disease (CD). METHODS: Initially, E coli strains expressing enhanced green fluorescent protein (pEGFP) were endomicroscopically imaged in mice. In addition, ex vivo and in vivo imaging of fluorescent human enteric bacteri…

Corrective factors of intestinal microflora disorders in the perinatal period

2019

Intestinal microflora is found at approximately 104 bacteria per ml of intestinal fluid. Although this ecosystem is very diverse with dynamic changes taking place within it, there is a certain stability in the type and number of species, referred to as the core microbiome, found in 95% of the human population. Genetic variation of microorganisms is relatively small, and their functions are strictly defined and highly conservative. The microbiome exists symbiotically with the host, protecting it against colonization by pathogenic microorganisms, providing essential metabolites, and stimulating the immune system. Colonization begins prenatally and its development is greatly influenced by the …

Microbial analysis of raw cows' milk used for cheese-making: influence of storage treatments on microbial composition and other technological traits

2010

Raw milk used to produce Grana cheese was subjected to several treatment regimes, including varying temperatures and storage times. Milk from morning and evening milking were transferred to a dairy factory sepa- rately (double delivery) or together (single delivery), after storage at the farm for 12 h; in the former case, milk was stored at 12 or 8°C, whereas, in the latter, it was kept at ambient temperature or 18°C. Values of pH of the vat milk were lower for milk samples kept at room temperature, while other physico-chemical parameters and rheological characteristics tested did not show significant differ- ences linked to the different storage temperatures of milk used for ‘‘Grana Trenti…

From gut microflora imbalance to mycobacteria infection: is there a relationship with chronic intestinal inflammatory diseases?

2011

The gut of a healthy adult harbours a myriad of different microbial species. It is estimated that approximately 10 14 are present in total bacterial colony forming units (CFU). Each colony colonizes a specific intestinal tract. In healthy adult, the main control of intestinal bacterial colonization occurs through gastric acidity but also other factors can influence the intestinal microenvironment such as pH, temperature, competition among different bacterial strains, peristalsis, drugs, radiotherapy and much more. Impaired microbial homeostasis leads to an alteration of the permeability of tissue, together with the activation of the intestinal immune system MALT (mucosal associated lymphoid…

Studies on the response of soil microflora to the application of the fungicide fenhexamid

2007

The aim of this work was to evaluate the impact of the fungicide fenhexamid (FEX) on the genetic structure of soil bacterial communities using the Ribosomal Intergenic Spacer Analysis molecular technique. Using real-time PCR, we also tried to quantify the pcaH sequences which encode the dioxygenases involved in the degradation process of a variety of aromatic compounds. Soil taken from a vineyard in the Etna Park (Sicily, Italy) was treated with FEX in the ratio 2 µg g-1 soil every 7 days, the process being repeated four times. The analyses were carried out before treatment and 7 days after each further application of FEX. At the same time, the degradation rate was evaluated. The use of FEX…

Enhanced isoproturon mineralisation in a clay silt loam agricultural soil

2005

International audience; 14C-ring-labelled isoproturon mineralisation was investigated in a French agricultural soil previously exposed to isoproturon. 50 different soil samples collected every 2 m along a transect of 100 m in length were treated one or two times with isoproturon under laboratory conditions and analysed by radiorespirometry. 94% of the soil samples showed a high ability to mineralise isoproturon with a relatively low variability in the cumulative percentage of mineralisation ranging from 30 to 51% of the initially added radioactivity for the samples treated once with the herbicide. About 45 to 67% of the initially added radioactivity was transformed into 14CO2 in soil sample…

Probiotiku izvēle atopiskā dermatīta gadījumos

2018

Alerģijas epidēmijas veicināšanā lielu lomu spēlē mūsdienu attīstītās sabiedrības dzīvesveids, kuru raksturo mikrobiālas floras nomākšana, tā izmainot cilvēka mikrobiotu un negatīvi ietekmējot imūno regulāciju (Fiocchi et al 2015). Maģistra darba mērķis bija noskaidrot dermatologu viedokli par atopisko dermatītu, ņemot vērā ārstēšanas vadlīnijas, un, izanalizējot zinātniskās publikācijas, izpētīt atopiskā dermatīta ārstēšanas tendences Latvijā, un izpētīt probiotiķu lomu atopiskā dermatīta profilaksē. Anketas aizpildīja ārsti – dermatologi (praktizējošie ārsti). Datu analīzei tika izmantotas 70 aptaujas. Secinājumi: Atopiskā dermatīta ārstēšanā visbiežāk izvēlas topiski lietojamos glokokort…
