in the current iranian poultry industry, antibiotics are the most frequently used additive in feeds to increase the productivity. regarding the negative effects on human health due to consuming chicken whose feeds contain antibiotics, finding an appropriate alternative is of a great importance. this study aims to find an appropriate and harmless feed additive to increase the quality and quantit...

conclusions the bacterial isolates exhibited strong biofilm formation potential, while the extracts of acacia arabica significantly inhibited biofilm formation among the isolates and, therefore, could be executed in the development of cost-effective biofilm inhibitor medicines. results pseudomonas aeruginosa (kc417303-05), staphylococcus hemolyticus (kc417306), and staphylococcus hominis (kc417...

This study revealed that the quantity of baeteria filtered from the base of Class V cavity restorations were directly related to the type of medicament used. Of the brands studied: composite, amalgam, sitieate, and guttapereha eaeh produeed varying numbers of bacterial eolonies, whereas zinc oxide and eugenol eement showed none. Histopathology of the pulps eorrelated direetly to the mierobiolog...

Bacterial T3SS needles formed by the protein MxiH are studied using DNP-enhanced ssNMR spectroscopy at 14.1 T (600 MHz). This technique provides spectra of good resolution, allowing us to draw conclusions about the protein dynamics. With the obtained signal enhancement, samples of limited quantity now get within reach of ssNMR studies.

Methods Defects were created in the stablised femurs of anaethetised rats, contaminated with Staphylococcus aureus and then debrided and irrigated six hours later. After 14 days, the bone and implants were harvested for separate microbiological analysis. This basic model was developed in several studies by varying the quantity of bacterial inoculation, introducing various doses of systemic anti...

The duration of infection and the quantity of Ag presented in vivo are commonly assumed to influence, if not determine, the magnitude of T cell responses. Although the cessation of in vivo T cell expansion coincides with bacterial clearance in mice infected with Listeria monocytogenes, closer analysis suggests that control of T cell expansion and contraction is more complex. In this report, we ...

Abstract Bacterial solutions have been studied to promote self-healing of cementitious matrices, however, the concentration this varied between studies. Consequently, objective study was evaluate potential different concentrations Bacillus subtilis AP91 encapsulated in expanded perlite (EP). Visual examination and capillary absorption water measured over time. Test samples were also subjected s...
