Biofilm

root canal system after endodontic treatment. These newly introduced microbes were not part of the previous infection and may have entered the root canal system through recurrent caries, exposed dentinal tubules or open marginal restorations. Unlike biofilms of primary endodontic infections which are polymicrobial, the bacteria causing persistent and secondary endodontic infections are usually composed of one or few species. It is thought that facultative bacteria are more resistant than…

aureus ability to adhere and form biofilm on host surfaces, and resistance to phagocytosis [210]. The production of biofilm by the microbes is reflected as a significant virulence factor responsible for connection of these microorganisms with living or non-living surfaces. Biofilm contents make a publication of bacteria and support them to stay alive in unfavorable environmental conditions. Staphylococcus aureus isolates which create biofilm lead to chronic mastitis in dairy animals as…

Without mechanical disruption, the biofilm will grow into a thick mature biofilm extending into the subgingival area (subgingival biofilm). The subgingival biofilms are comprised of mostly Gram-negative, anaerobic bacteria which lead to the deposition of virulence factors into the gingival crevicular fluid (GCF). These substances can cause injury to…

In a series of trials, treating of DUWLs with sodium hypochlorite, glutaraldehyde, and isopropanol was investigated. These agents reduced microorganisms in effluent water but did not destroy the biofilm matrix in the DUWLs, even with periodic treatments [ 8].Similar results were obtained for Listerine, Bio 2000, Rembrandt, and Sodium fluoride [ 23].There are now an increasing number of commercial disinfectants that practice managers can use to reduce…

colonize available surfaces and form biofilms (Huang et al., 2007). Marine bacteria transition from planktonic organisms to members of a firmly attached benthic community. Biofilms play an important role in many marine invertebrate lifecycles that similarly transition from a planktonic to sessile benthic phase. The larvae of marine invertebrates like sponges and polychaetes settle in response to chemical cues from biofilms. Hydroides elegans is a model organism for biofilm-induced settlement as…

The formation of a biofilm continued even in the presence of this poison, suggesting that nanobacteria may not be alive after all. However, it could be that nanobacteria are immune or highly insusceptible to sodium azide, which would explain why the formation of biofilm continued even after the inhibitor was added. It’s salient to note that traditional microbiological methods fail to reveal nanobacteria…

Conclusion The bathroom stands as an important point in the transmission of infection in the community and the entire environment as it houses various varieties of microorganisms, which may be potential pathogens or pathogenic themselves, in the form of biofilms, and may become a threat to immono-compromised or ill persons as shown by the results of this study. Continous use of these bathrooms without knowing the different type of organisms colonizing these areas therefore, is a public health…

Table 2. Results for the antimicrobial susceptibility tests using the BSAC method Organism Microbial Resistance (mm) CFX CXM CTX CPM Control 310217 704476/2 706498 310258 CFX = Cefalexin. CXM = Cefuroxime. CTX = Cefotaxime. CPM = Cefepime. R = Resistant. S = Sensitive. Table 2 highlights resistance/sensitive of the dissimilar microorganisms to the different sorts of antibiotics. Data of table 2 demonstrates that E.coli strains produced sort of difference in resistance.…

However, the staphylococcal intoxication remains a very common food poisoning. Bacteria most commonly live by adhering to surfaces and forming organized communities called biofilms (Malheiros et al., 2010). Staphylococcus aureus also known as pathogenic bacterium that capable in developing biofilms formation especially on food processing surfaces in which that is a pathway leading to cross contamination of foods (Ciccio et al., 2015). The human beings are a major reservoir for the post-process…

e. Mulgaon and Kulgaon. From this survey an attempt was made to correlate the food habits, oral hygiene and their influence in dental plaque formation. The data obtained from the patients from rural and urban region were compared with the type of biofilm and the type of clinical symptoms. Frequency of each individual parameter was calculated and it was checked for its relation with the dental plaque formation. A questionnaire was designed which included gender, age, food habit, frequency of tea…
